+Cross-Thread Return Address Predictions
+=======================================
+
+Certain AMD and Hygon processors are subject to a cross-thread return address
+predictions vulnerability. When running in SMT mode and one sibling thread
+transitions out of C0 state, the other sibling thread could use return target
+predictions from the sibling thread that transitioned out of C0.
+
+The Spectre v2 mitigations protect the Linux kernel, as it fills the return
+address prediction entries with safe targets when context switching to the idle
+thread. However, KVM does allow a VMM to prevent exiting guest mode when
+transitioning out of C0. This could result in a guest-controlled return target
+being consumed by the sibling thread.
+
+Affected processors
+-------------------
+
+The following CPUs are vulnerable:
+
+    - AMD Family 17h processors
+    - Hygon Family 18h processors
+
+Related CVEs
+------------
+
+The following CVE entry is related to this issue:
+
+   ==============  =======================================
+   CVE-2022-27672  Cross-Thread Return Address Predictions
+   ==============  =======================================
+
+Problem
+-------
+
+Affected SMT-capable processors support 1T and 2T modes of execution when SMT
+is enabled. In 2T mode, both threads in a core are executing code. For the
+processor core to enter 1T mode, it is required that one of the threads
+requests to transition out of the C0 state. This can be communicated with the
+HLT instruction or with an MWAIT instruction that requests non-C0.
+When the thread re-enters the C0 state, the processor transitions back
+to 2T mode, assuming the other thread is also still in C0 state.
+
+In affected processors, the return address predictor (RAP) is partitioned
+depending on the SMT mode. For instance, in 2T mode each thread uses a private
+16-entry RAP, but in 1T mode, the active thread uses a 32-entry RAP. Upon
+transition between 1T/2T mode, the RAP contents are not modified but the RAP
+pointers (which control the next return target to use for predictions) may
+change. This behavior may result in return targets from one SMT thread being
+used by RET predictions in the sibling thread following a 1T/2T switch. In
+particular, a RET instruction executed immediately after a transition to 1T may
+use a return target from the thread that just became idle. In theory, this
+could lead to information disclosure if the return targets used do not come
+from trustworthy code.
+
+Attack scenarios
+----------------
+
+An attack can be mounted on affected processors by performing a series of CALL
+instructions with targeted return locations and then transitioning out of C0
+state.
+
+Mitigation mechanism
+--------------------
+
+Before entering idle state, the kernel context switches to the idle thread. The
+context switch fills the RAP entries (referred to as the RSB in Linux) with safe
+targets by performing a sequence of CALL instructions.
+
+Prevent a guest VM from directly putting the processor into an idle state by
+intercepting HLT and MWAIT instructions.
+
+Both mitigations are required to fully address this issue.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+
+Use existing Spectre v2 mitigations that will fill the RSB on context switch.
+
+Mitigation control for KVM - module parameter
+---------------------------------------------
+
+By default, the KVM hypervisor mitigates this issue by intercepting guest
+attempts to transition out of C0. A VMM can use the KVM_CAP_X86_DISABLE_EXITS
+capability to override those interceptions, but since this is not common, the
+mitigation that covers this path is not enabled by default.
+
+The mitigation for the KVM_CAP_X86_DISABLE_EXITS capability can be turned on
+using the boolean module parameter mitigate_smt_rsb, e.g.:
+        kvm.mitigate_smt_rsb=1

+GDS - Gather Data Sampling
+==========================
+
+Gather Data Sampling is a hardware vulnerability which allows unprivileged
+speculative access to data which was previously stored in vector registers.
+
+Problem
+-------
+When a gather instruction performs loads from memory, different data elements
+are merged into the destination vector register. However, when a gather
+instruction that is transiently executed encounters a fault, stale data from
+architectural or internal vector registers may get transiently forwarded to the
+destination vector register instead. This will allow a malicious attacker to
+infer stale data using typical side channel techniques like cache timing
+attacks. GDS is a purely sampling-based attack.
+
+The attacker uses gather instructions to infer the stale vector register data.
+The victim does not need to do anything special other than use the vector
+registers. The victim does not need to use gather instructions to be
+vulnerable.
+
+Because the buffers are shared between Hyper-Threads cross Hyper-Thread attacks
+are possible.
+
+Attack scenarios
+----------------
+Without mitigation, GDS can infer stale data across virtually all
+permission boundaries:
+
+	Non-enclaves can infer SGX enclave data
+	Userspace can infer kernel data
+	Guests can infer data from hosts
+	Guest can infer guest from other guests
+	Users can infer data from other users
+
+Because of this, it is important to ensure that the mitigation stays enabled in
+lower-privilege contexts like guests and when running outside SGX enclaves.
+
+The hardware enforces the mitigation for SGX. Likewise, VMMs should  ensure
+that guests are not allowed to disable the GDS mitigation. If a host erred and
+allowed this, a guest could theoretically disable GDS mitigation, mount an
+attack, and re-enable it.
+
+Mitigation mechanism
+--------------------
+This issue is mitigated in microcode. The microcode defines the following new
+bits:
+
+ ================================   ===   ============================
+ IA32_ARCH_CAPABILITIES[GDS_CTRL]   R/O   Enumerates GDS vulnerability
+                                          and mitigation support.
+ IA32_ARCH_CAPABILITIES[GDS_NO]     R/O   Processor is not vulnerable.
+ IA32_MCU_OPT_CTRL[GDS_MITG_DIS]    R/W   Disables the mitigation
+                                          0 by default.
+ IA32_MCU_OPT_CTRL[GDS_MITG_LOCK]   R/W   Locks GDS_MITG_DIS=0. Writes
+                                          to GDS_MITG_DIS are ignored
+                                          Can't be cleared once set.
+ ================================   ===   ============================
+
+GDS can also be mitigated on systems that don't have updated microcode by
+disabling AVX. This can be done by setting gather_data_sampling="force" or
+"clearcpuid=avx" on the kernel command-line.
+
+If used, these options will disable AVX use by turning off XSAVE YMM support.
+However, the processor will still enumerate AVX support.  Userspace that
+does not follow proper AVX enumeration to check both AVX *and* XSAVE YMM
+support will break.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+The mitigation can be disabled by setting "gather_data_sampling=off" or
+"mitigations=off" on the kernel command line. Not specifying either will default
+to the mitigation being enabled. Specifying "gather_data_sampling=force" will
+use the microcode mitigation when available or disable AVX on affected systems
+where the microcode hasn't been updated to include the mitigation.
+
+GDS System Information
+------------------------
+The kernel provides vulnerability status information through sysfs. For
+GDS this can be accessed by the following sysfs file:
+
+/sys/devices/system/cpu/vulnerabilities/gather_data_sampling

+=========================================
+Processor MMIO Stale Data Vulnerabilities
+=========================================
+
+Processor MMIO Stale Data Vulnerabilities are a class of memory-mapped I/O
+(MMIO) vulnerabilities that can expose data. The sequences of operations for
+exposing data range from simple to very complex. Because most of the
+vulnerabilities require the attacker to have access to MMIO, many environments
+are not affected. System environments using virtualization where MMIO access is
+provided to untrusted guests may need mitigation. These vulnerabilities are
+not transient execution attacks. However, these vulnerabilities may propagate
+stale data into core fill buffers where the data can subsequently be inferred
+by an unmitigated transient execution attack. Mitigation for these
+vulnerabilities includes a combination of microcode update and software
+changes, depending on the platform and usage model. Some of these mitigations
+are similar to those used to mitigate Microarchitectural Data Sampling (MDS) or
+those used to mitigate Special Register Buffer Data Sampling (SRBDS).
+
+Data Propagators
+================
+Propagators are operations that result in stale data being copied or moved from
+one microarchitectural buffer or register to another. Processor MMIO Stale Data
+Vulnerabilities are operations that may result in stale data being directly
+read into an architectural, software-visible state or sampled from a buffer or
+register.
+
+Fill Buffer Stale Data Propagator (FBSDP)
+-----------------------------------------
+Stale data may propagate from fill buffers (FB) into the non-coherent portion
+of the uncore on some non-coherent writes. Fill buffer propagation by itself
+does not make stale data architecturally visible. Stale data must be propagated
+to a location where it is subject to reading or sampling.
+
+Sideband Stale Data Propagator (SSDP)
+-------------------------------------
+The sideband stale data propagator (SSDP) is limited to the client (including
+Intel Xeon server E3) uncore implementation. The sideband response buffer is
+shared by all client cores. For non-coherent reads that go to sideband
+destinations, the uncore logic returns 64 bytes of data to the core, including
+both requested data and unrequested stale data, from a transaction buffer and
+the sideband response buffer. As a result, stale data from the sideband
+response and transaction buffers may now reside in a core fill buffer.
+
+Primary Stale Data Propagator (PSDP)
+------------------------------------
+The primary stale data propagator (PSDP) is limited to the client (including
+Intel Xeon server E3) uncore implementation. Similar to the sideband response
+buffer, the primary response buffer is shared by all client cores. For some
+processors, MMIO primary reads will return 64 bytes of data to the core fill
+buffer including both requested data and unrequested stale data. This is
+similar to the sideband stale data propagator.
+
+Vulnerabilities
+===============
+Device Register Partial Write (DRPW) (CVE-2022-21166)
+-----------------------------------------------------
+Some endpoint MMIO registers incorrectly handle writes that are smaller than
+the register size. Instead of aborting the write or only copying the correct
+subset of bytes (for example, 2 bytes for a 2-byte write), more bytes than
+specified by the write transaction may be written to the register. On
+processors affected by FBSDP, this may expose stale data from the fill buffers
+of the core that created the write transaction.
+
+Shared Buffers Data Sampling (SBDS) (CVE-2022-21125)
+----------------------------------------------------
+After propagators may have moved data around the uncore and copied stale data
+into client core fill buffers, processors affected by MFBDS can leak data from
+the fill buffer. It is limited to the client (including Intel Xeon server E3)
+uncore implementation.
+
+Shared Buffers Data Read (SBDR) (CVE-2022-21123)
+------------------------------------------------
+It is similar to Shared Buffer Data Sampling (SBDS) except that the data is
+directly read into the architectural software-visible state. It is limited to
+the client (including Intel Xeon server E3) uncore implementation.
+
+Affected Processors
+===================
+Not all the CPUs are affected by all the variants. For instance, most
+processors for the server market (excluding Intel Xeon E3 processors) are
+impacted by only Device Register Partial Write (DRPW).
+

+
+If a CPU is in the affected processor list, but not affected by a variant, it
+is indicated by new bits in MSR IA32_ARCH_CAPABILITIES. As described in a later
+section, mitigation largely remains the same for all the variants, i.e. to
+clear the CPU fill buffers via VERW instruction.
+
+New bits in MSRs
+================
+Newer processors and microcode update on existing affected processors added new
+bits to IA32_ARCH_CAPABILITIES MSR. These bits can be used to enumerate
+specific variants of Processor MMIO Stale Data vulnerabilities and mitigation
+capability.
+
+MSR IA32_ARCH_CAPABILITIES
+--------------------------
+Bit 13 - SBDR_SSDP_NO - When set, processor is not affected by either the
+	 Shared Buffers Data Read (SBDR) vulnerability or the sideband stale
+	 data propagator (SSDP).
+Bit 14 - FBSDP_NO - When set, processor is not affected by the Fill Buffer
+	 Stale Data Propagator (FBSDP).
+Bit 15 - PSDP_NO - When set, processor is not affected by Primary Stale Data
+	 Propagator (PSDP).
+Bit 17 - FB_CLEAR - When set, VERW instruction will overwrite CPU fill buffer
+	 values as part of MD_CLEAR operations. Processors that do not
+	 enumerate MDS_NO (meaning they are affected by MDS) but that do
+	 enumerate support for both L1D_FLUSH and MD_CLEAR implicitly enumerate
+	 FB_CLEAR as part of their MD_CLEAR support.
+Bit 18 - FB_CLEAR_CTRL - Processor supports read and write to MSR
+	 IA32_MCU_OPT_CTRL[FB_CLEAR_DIS]. On such processors, the FB_CLEAR_DIS
+	 bit can be set to cause the VERW instruction to not perform the
+	 FB_CLEAR action. Not all processors that support FB_CLEAR will support
+	 FB_CLEAR_CTRL.
+
+MSR IA32_MCU_OPT_CTRL
+---------------------
+Bit 3 - FB_CLEAR_DIS - When set, VERW instruction does not perform the FB_CLEAR
+action. This may be useful to reduce the performance impact of FB_CLEAR in
+cases where system software deems it warranted (for example, when performance
+is more critical, or the untrusted software has no MMIO access). Note that
+FB_CLEAR_DIS has no impact on enumeration (for example, it does not change
+FB_CLEAR or MD_CLEAR enumeration) and it may not be supported on all processors
+that enumerate FB_CLEAR.
+
+Mitigation
+==========
+Like MDS, all variants of Processor MMIO Stale Data vulnerabilities  have the
+same mitigation strategy to force the CPU to clear the affected buffers before
+an attacker can extract the secrets.
+
+This is achieved by using the otherwise unused and obsolete VERW instruction in
+combination with a microcode update. The microcode clears the affected CPU
+buffers when the VERW instruction is executed.
+
+Kernel reuses the MDS function to invoke the buffer clearing:
+
+	mds_clear_cpu_buffers()
+
+On MDS affected CPUs, the kernel already invokes CPU buffer clear on
+kernel/userspace, hypervisor/guest and C-state (idle) transitions. No
+additional mitigation is needed on such CPUs.
+
+For CPUs not affected by MDS or TAA, mitigation is needed only for the attacker
+with MMIO capability. Therefore, VERW is not required for kernel/userspace. For
+virtualization case, VERW is only needed at VMENTER for a guest with MMIO
+capability.
+
+Mitigation points
+-----------------
+Return to user space
+^^^^^^^^^^^^^^^^^^^^
+Same mitigation as MDS when affected by MDS/TAA, otherwise no mitigation
+needed.
+
+C-State transition
+^^^^^^^^^^^^^^^^^^
+Control register writes by CPU during C-state transition can propagate data
+from fill buffer to uncore buffers. Execute VERW before C-state transition to
+clear CPU fill buffers.
+
+Guest entry point
+^^^^^^^^^^^^^^^^^
+Same mitigation as MDS when processor is also affected by MDS/TAA, otherwise
+execute VERW at VMENTER only for MMIO capable guests. On CPUs not affected by
+MDS/TAA, guest without MMIO access cannot extract secrets using Processor MMIO
+Stale Data vulnerabilities, so there is no need to execute VERW for such guests.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+The kernel command line allows to control the Processor MMIO Stale Data
+mitigations at boot time with the option "mmio_stale_data=". The valid
+arguments for this option are:
+
+  ==========  =================================================================
+  full        If the CPU is vulnerable, enable mitigation; CPU buffer clearing
+              on exit to userspace and when entering a VM. Idle transitions are
+              protected as well. It does not automatically disable SMT.
+  full,nosmt  Same as full, with SMT disabled on vulnerable CPUs. This is the
+              complete mitigation.
+  off         Disables mitigation completely.
+  ==========  =================================================================
+
+If the CPU is affected and mmio_stale_data=off is not supplied on the kernel
+command line, then the kernel selects the appropriate mitigation.
+
+Mitigation status information
+-----------------------------
+The Linux kernel provides a sysfs interface to enumerate the current
+vulnerability status of the system: whether the system is vulnerable, and
+which mitigations are active. The relevant sysfs file is:
+

+SRBDS - Special Register Buffer Data Sampling
+=============================================
+
+SRBDS is a hardware vulnerability that allows MDS :doc:`mds` techniques to
+infer values returned from special register accesses.  Special register
+accesses are accesses to off core registers.  According to Intel's evaluation,
+the special register reads that have a security expectation of privacy are
+RDRAND, RDSEED and SGX EGETKEY.
+
+When RDRAND, RDSEED and EGETKEY instructions are used, the data is moved
+to the core through the special register mechanism that is susceptible
+to MDS attacks.
+
+Affected processors
+--------------------
+Core models (desktop, mobile, Xeon-E3) that implement RDRAND and/or RDSEED may
+be affected.
+
+A processor is affected by SRBDS if its Family_Model and stepping is
+in the following list, with the exception of the listed processors
+exporting MDS_NO while Intel TSX is available yet not enabled. The
+latter class of processors are only affected when Intel TSX is enabled
+by software using TSX_CTRL_MSR otherwise they are not affected.

+    ==============  =====  =====================================
+
+Attack scenarios
+----------------
+An unprivileged user can extract values returned from RDRAND and RDSEED
+executed on another core or sibling thread using MDS techniques.
+
+
+Mitigation mechanism
+-------------------
+Intel will release microcode updates that modify the RDRAND, RDSEED, and
+EGETKEY instructions to overwrite secret special register data in the shared
+staging buffer before the secret data can be accessed by another logical
+processor.
+
+During execution of the RDRAND, RDSEED, or EGETKEY instructions, off-core
+accesses from other logical processors will be delayed until the special
+register read is complete and the secret data in the shared staging buffer is
+overwritten.
+
+This has three effects on performance:
+
+#. RDRAND, RDSEED, or EGETKEY instructions have higher latency.
+
+#. Executing RDRAND at the same time on multiple logical processors will be
+   serialized, resulting in an overall reduction in the maximum RDRAND
+   bandwidth.
+
+#. Executing RDRAND, RDSEED or EGETKEY will delay memory accesses from other
+   logical processors that miss their core caches, with an impact similar to
+   legacy locked cache-line-split accesses.
+
+The microcode updates provide an opt-out mechanism (RNGDS_MITG_DIS) to disable
+the mitigation for RDRAND and RDSEED instructions executed outside of Intel
+Software Guard Extensions (Intel SGX) enclaves. On logical processors that
+disable the mitigation using this opt-out mechanism, RDRAND and RDSEED do not
+take longer to execute and do not impact performance of sibling logical
+processors memory accesses. The opt-out mechanism does not affect Intel SGX
+enclaves (including execution of RDRAND or RDSEED inside an enclave, as well
+as EGETKEY execution).
+
+IA32_MCU_OPT_CTRL MSR Definition
+--------------------------------
+Along with the mitigation for this issue, Intel added a new thread-scope
+IA32_MCU_OPT_CTRL MSR, (address 0x123). The presence of this MSR and
+RNGDS_MITG_DIS (bit 0) is enumerated by CPUID.(EAX=07H,ECX=0).EDX[SRBDS_CTRL =
+9]==1. This MSR is introduced through the microcode update.
+
+Setting IA32_MCU_OPT_CTRL[0] (RNGDS_MITG_DIS) to 1 for a logical processor
+disables the mitigation for RDRAND and RDSEED executed outside of an Intel SGX
+enclave on that logical processor. Opting out of the mitigation for a
+particular logical processor does not affect the RDRAND and RDSEED mitigations
+for other logical processors.
+
+Note that inside of an Intel SGX enclave, the mitigation is applied regardless
+of the value of RNGDS_MITG_DS.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+The kernel command line allows control over the SRBDS mitigation at boot time
+with the option "srbds=".  The option for this is:
+
+  ============= =============================================================
+  off           This option disables SRBDS mitigation for RDRAND and RDSEED on
+                affected platforms.
+  ============= =============================================================
+
+SRBDS System Information
+-----------------------
+The Linux kernel provides vulnerability status information through sysfs.  For
+SRBDS this can be accessed by the following sysfs file:
+/sys/devices/system/cpu/vulnerabilities/srbds

+
+SRBDS Default mitigation
+------------------------
+This new microcode serializes processor access during execution of RDRAND,
+RDSEED ensures that the shared buffer is overwritten before it is released for

+RDRAND and RDSEED.

+Assembler Annotations
+=====================
+
+Copyright (c) 2017-2019 Jiri Slaby
+
+This document describes the new macros for annotation of data and code in
+assembly. In particular, it contains information about ``SYM_FUNC_START``,
+``SYM_FUNC_END``, ``SYM_CODE_START``, and similar.
+
+Rationale
+---------
+Some code like entries, trampolines, or boot code needs to be written in
+assembly. The same as in C, such code is grouped into functions and
+accompanied with data. Standard assemblers do not force users into precisely
+marking these pieces as code, data, or even specifying their length.
+Nevertheless, assemblers provide developers with such annotations to aid
+debuggers throughout assembly. On top of that, developers also want to mark
+some functions as *global* in order to be visible outside of their translation
+units.
+
+Over time, the Linux kernel has adopted macros from various projects (like
+``binutils``) to facilitate such annotations. So for historic reasons,
+developers have been using ``ENTRY``, ``END``, ``ENDPROC``, and other
+annotations in assembly.  Due to the lack of their documentation, the macros
+are used in rather wrong contexts at some locations. Clearly, ``ENTRY`` was
+intended to denote the beginning of global symbols (be it data or code).
+``END`` used to mark the end of data or end of special functions with
+*non-standard* calling convention. In contrast, ``ENDPROC`` should annotate
+only ends of *standard* functions.
+
+When these macros are used correctly, they help assemblers generate a nice
+object with both sizes and types set correctly. For example, the result of
+``arch/x86/lib/putuser.S``::
+
+   Num:    Value          Size Type    Bind   Vis      Ndx Name
+    25: 0000000000000000    33 FUNC    GLOBAL DEFAULT    1 __put_user_1
+    29: 0000000000000030    37 FUNC    GLOBAL DEFAULT    1 __put_user_2
+    32: 0000000000000060    36 FUNC    GLOBAL DEFAULT    1 __put_user_4
+    35: 0000000000000090    37 FUNC    GLOBAL DEFAULT    1 __put_user_8
+
+This is not only important for debugging purposes. When there are properly
+annotated objects like this, tools can be run on them to generate more useful
+information. In particular, on properly annotated objects, ``objtool`` can be
+run to check and fix the object if needed. Currently, ``objtool`` can report
+missing frame pointer setup/destruction in functions. It can also
+automatically generate annotations for :doc:`ORC unwinder <x86/orc-unwinder>`
+for most code. Both of these are especially important to support reliable
+stack traces which are in turn necessary for :doc:`Kernel live patching
+<livepatch/livepatch>`.
+
+Caveat and Discussion
+---------------------
+As one might realize, there were only three macros previously. That is indeed
+insufficient to cover all the combinations of cases:
+
+* standard/non-standard function
+* code/data
+* global/local symbol
+
+There was a discussion_ and instead of extending the current ``ENTRY/END*``
+macros, it was decided that brand new macros should be introduced instead::
+
+    So how about using macro names that actually show the purpose, instead
+    of importing all the crappy, historic, essentially randomly chosen
+    debug symbol macro names from the binutils and older kernels?
+
+.. _discussion: https://lkml.kernel.org/r/20170217104757.28588-1-jslaby@suse.cz
+
+Macros Description
+------------------
+
+The new macros are prefixed with the ``SYM_`` prefix and can be divided into
+three main groups:
+
+1. ``SYM_FUNC_*`` -- to annotate C-like functions. This means functions with
+   standard C calling conventions, i.e. the stack contains a return address at
+   the predefined place and a return from the function can happen in a
+   standard way. When frame pointers are enabled, save/restore of frame
+   pointer shall happen at the start/end of a function, respectively, too.
+
+   Checking tools like ``objtool`` should ensure such marked functions conform
+   to these rules. The tools can also easily annotate these functions with
+   debugging information (like *ORC data*) automatically.
+
+2. ``SYM_CODE_*`` -- special functions called with special stack. Be it
+   interrupt handlers with special stack content, trampolines, or startup
+   functions.
+
+   Checking tools mostly ignore checking of these functions. But some debug
+   information still can be generated automatically. For correct debug data,
+   this code needs hints like ``UNWIND_HINT_REGS`` provided by developers.
+
+3. ``SYM_DATA*`` -- obviously data belonging to ``.data`` sections and not to
+   ``.text``. Data do not contain instructions, so they have to be treated
+   specially by the tools: they should not treat the bytes as instructions,
+   nor assign any debug information to them.
+
+Instruction Macros
+~~~~~~~~~~~~~~~~~~
+This section covers ``SYM_FUNC_*`` and ``SYM_CODE_*`` enumerated above.
+
+* ``SYM_FUNC_START`` and ``SYM_FUNC_START_LOCAL`` are supposed to be **the
+  most frequent markings**. They are used for functions with standard calling
+  conventions -- global and local. Like in C, they both align the functions to
+  architecture specific ``__ALIGN`` bytes. There are also ``_NOALIGN`` variants
+  for special cases where developers do not want this implicit alignment.
+
+  ``SYM_FUNC_START_WEAK`` and ``SYM_FUNC_START_WEAK_NOALIGN`` markings are
+  also offered as an assembler counterpart to the *weak* attribute known from
+  C.
+
+  All of these **shall** be coupled with ``SYM_FUNC_END``. First, it marks
+  the sequence of instructions as a function and computes its size to the
+  generated object file. Second, it also eases checking and processing such
+  object files as the tools can trivially find exact function boundaries.
+
+  So in most cases, developers should write something like in the following
+  example, having some asm instructions in between the macros, of course::
+
+    SYM_FUNC_START(function_hook)
+        ... asm insns ...
+    SYM_FUNC_END(function_hook)
+
+  In fact, this kind of annotation corresponds to the now deprecated ``ENTRY``
+  and ``ENDPROC`` macros.
+
+* ``SYM_FUNC_START_ALIAS`` and ``SYM_FUNC_START_LOCAL_ALIAS`` serve for those
+  who decided to have two or more names for one function. The typical use is::
+
+    SYM_FUNC_START_ALIAS(__memset)
+    SYM_FUNC_START(memset)
+        ... asm insns ...
+    SYM_FUNC_END(memset)
+    SYM_FUNC_END_ALIAS(__memset)
+
+  In this example, one can call ``__memset`` or ``memset`` with the same
+  result, except the debug information for the instructions is generated to
+  the object file only once -- for the non-``ALIAS`` case.
+
+* ``SYM_CODE_START`` and ``SYM_CODE_START_LOCAL`` should be used only in
+  special cases -- if you know what you are doing. This is used exclusively
+  for interrupt handlers and similar where the calling convention is not the C
+  one. ``_NOALIGN`` variants exist too. The use is the same as for the ``FUNC``
+  category above::
+
+    SYM_CODE_START_LOCAL(bad_put_user)
+        ... asm insns ...
+    SYM_CODE_END(bad_put_user)
+
+  Again, every ``SYM_CODE_START*`` **shall** be coupled by ``SYM_CODE_END``.
+
+  To some extent, this category corresponds to deprecated ``ENTRY`` and
+  ``END``. Except ``END`` had several other meanings too.
+
+* ``SYM_INNER_LABEL*`` is used to denote a label inside some
+  ``SYM_{CODE,FUNC}_START`` and ``SYM_{CODE,FUNC}_END``.  They are very similar
+  to C labels, except they can be made global. An example of use::
+
+    SYM_CODE_START(ftrace_caller)
+        /* save_mcount_regs fills in first two parameters */
+        ...
+
+    SYM_INNER_LABEL(ftrace_caller_op_ptr, SYM_L_GLOBAL)
+        /* Load the ftrace_ops into the 3rd parameter */
+        ...
+
+    SYM_INNER_LABEL(ftrace_call, SYM_L_GLOBAL)
+        call ftrace_stub
+        ...
+        retq
+    SYM_CODE_END(ftrace_caller)
+
+Data Macros
+~~~~~~~~~~~
+Similar to instructions, there is a couple of macros to describe data in the
+assembly.
+
+* ``SYM_DATA_START`` and ``SYM_DATA_START_LOCAL`` mark the start of some data
+  and shall be used in conjunction with either ``SYM_DATA_END``, or
+  ``SYM_DATA_END_LABEL``. The latter adds also a label to the end, so that
+  people can use ``lstack`` and (local) ``lstack_end`` in the following
+  example::
+
+    SYM_DATA_START_LOCAL(lstack)
+        .skip 4096
+    SYM_DATA_END_LABEL(lstack, SYM_L_LOCAL, lstack_end)
+
+* ``SYM_DATA`` and ``SYM_DATA_LOCAL`` are variants for simple, mostly one-line
+  data::
+
+    SYM_DATA(HEAP,     .long rm_heap)
+    SYM_DATA(heap_end, .long rm_stack)
+
+  In the end, they expand to ``SYM_DATA_START`` with ``SYM_DATA_END``
+  internally.
+
+Support Macros
+~~~~~~~~~~~~~~
+All the above reduce themselves to some invocation of ``SYM_START``,
+``SYM_END``, or ``SYM_ENTRY`` at last. Normally, developers should avoid using
+these.
+
+Further, in the above examples, one could see ``SYM_L_LOCAL``. There are also
+``SYM_L_GLOBAL`` and ``SYM_L_WEAK``. All are intended to denote linkage of a
+symbol marked by them. They are used either in ``_LABEL`` variants of the
+earlier macros, or in ``SYM_START``.
+
+
+Overriding Macros
+~~~~~~~~~~~~~~~~~
+Architecture can also override any of the macros in their own
+``asm/linkage.h``, including macros specifying the type of a symbol
+(``SYM_T_FUNC``, ``SYM_T_OBJECT``, and ``SYM_T_NONE``).  As every macro
+described in this file is surrounded by ``#ifdef`` + ``#endif``, it is enough
+to define the macros differently in the aforementioned architecture-dependent
+header.

+			CGroup Namespaces
+
+CGroup Namespace provides a mechanism to virtualize the view of the
+/proc/<pid>/cgroup file. The CLONE_NEWCGROUP clone-flag can be used with
+clone() and unshare() syscalls to create a new cgroup namespace.
+The process running inside the cgroup namespace will have its /proc/<pid>/cgroup
+output restricted to cgroupns-root. cgroupns-root is the cgroup of the process
+at the time of creation of the cgroup namespace.
+
+Prior to CGroup Namespace, the /proc/<pid>/cgroup file used to show complete
+path of the cgroup of a process. In a container setup (where a set of cgroups
+and namespaces are intended to isolate processes), the /proc/<pid>/cgroup file
+may leak potential system level information to the isolated processes.
+
+For Example:
+  $ cat /proc/self/cgroup
+  0:cpuset,cpu,cpuacct,memory,devices,freezer,hugetlb:/batchjobs/container_id1
+
+The path '/batchjobs/container_id1' can generally be considered as system-data
+and its desirable to not expose it to the isolated process.
+
+CGroup Namespaces can be used to restrict visibility of this path.
+For Example:
+  # Before creating cgroup namespace
+  $ ls -l /proc/self/ns/cgroup
+  lrwxrwxrwx 1 root root 0 2014-07-15 10:37 /proc/self/ns/cgroup -> cgroup:[4026531835]
+  $ cat /proc/self/cgroup
+  0:cpuset,cpu,cpuacct,memory,devices,freezer,hugetlb:/batchjobs/container_id1
+
+  # unshare(CLONE_NEWCGROUP) and exec /bin/bash
+  $ ~/unshare -c
+  [ns]$ ls -l /proc/self/ns/cgroup
+  lrwxrwxrwx 1 root root 0 2014-07-15 10:35 /proc/self/ns/cgroup -> cgroup:[4026532183]
+  # From within new cgroupns, process sees that its in the root cgroup
+  [ns]$ cat /proc/self/cgroup
+  0:cpuset,cpu,cpuacct,memory,devices,freezer,hugetlb:/
+
+  # From global cgroupns:
+  $ cat /proc/<pid>/cgroup
+  0:cpuset,cpu,cpuacct,memory,devices,freezer,hugetlb:/batchjobs/container_id1
+
+  # Unshare cgroupns along with userns and mountns
+  # Following calls unshare(CLONE_NEWCGROUP|CLONE_NEWUSER|CLONE_NEWNS), then
+  # sets up uid/gid map and execs /bin/bash
+  $ ~/unshare -c -u -m
+  # Originally, we were in /batchjobs/container_id1 cgroup. Mount our own cgroup
+  # hierarchy.
+  [ns]$ mount -t cgroup cgroup /tmp/cgroup
+  [ns]$ ls -l /tmp/cgroup
+  total 0
+  -r--r--r-- 1 root root 0 2014-10-13 09:32 cgroup.controllers
+  -r--r--r-- 1 root root 0 2014-10-13 09:32 cgroup.populated
+  -rw-r--r-- 1 root root 0 2014-10-13 09:25 cgroup.procs
+  -rw-r--r-- 1 root root 0 2014-10-13 09:32 cgroup.subtree_control
+
+The cgroupns-root (/batchjobs/container_id1 in above example) becomes the
+filesystem root for the namespace specific cgroupfs mount.
+
+The virtualization of /proc/self/cgroup file combined with restricting
+the view of cgroup hierarchy by namespace-private cgroupfs mount
+should provide a completely isolated cgroup view inside the container.
+
+In its current form, the cgroup namespaces patcheset provides following
+behavior:
+
+(1) The 'cgroupns-root' for a cgroup namespace is the cgroup in which
+    the process calling unshare is running.
+    For ex. if a process in /batchjobs/container_id1 cgroup calls unshare,
+    cgroup /batchjobs/container_id1 becomes the cgroupns-root.
+    For the init_cgroup_ns, this is the real root ('/') cgroup
+    (identified in code as cgrp_dfl_root.cgrp).
+
+(2) The cgroupns-root cgroup does not change even if the namespace
+    creator process later moves to a different cgroup.
+    $ ~/unshare -c # unshare cgroupns in some cgroup
+    [ns]$ cat /proc/self/cgroup
+    0:cpuset,cpu,cpuacct,memory,devices,freezer,hugetlb:/
+    [ns]$ mkdir sub_cgrp_1
+    [ns]$ echo 0 > sub_cgrp_1/cgroup.procs
+    [ns]$ cat /proc/self/cgroup
+    0:cpuset,cpu,cpuacct,memory,devices,freezer,hugetlb:/sub_cgrp_1
+
+(3) Each process gets its CGROUPNS specific view of /proc/<pid>/cgroup
+(a) Processes running inside the cgroup namespace will be able to see
+    cgroup paths (in /proc/self/cgroup) only inside their root cgroup
+    [ns]$ sleep 100000 &  # From within unshared cgroupns
+    [1] 7353
+    [ns]$ echo 7353 > sub_cgrp_1/cgroup.procs
+    [ns]$ cat /proc/7353/cgroup
+    0:cpuset,cpu,cpuacct,memory,devices,freezer,hugetlb:/sub_cgrp_1
+
+(b) From global cgroupns, the real cgroup path will be visible:
+    $ cat /proc/7353/cgroup
+    0:cpuset,cpu,cpuacct,memory,devices,freezer,hugetlb:/batchjobs/container_id1/sub_cgrp_1
+
+(c) From a sibling cgroupns (cgroupns root-ed at a different cgroup), cgroup
+    path relative to its own cgroupns-root will be shown:
+    # ns2's cgroupns-root is at '/batchjobs/container_id2'
+    [ns2]$ cat /proc/7353/cgroup
+    0:cpuset,cpu,cpuacct,memory,devices,freezer,hugetlb:/../container_id2/sub_cgrp_1
+
+    Note that the relative path always starts with '/' to indicate that its
+    relative to the cgroupns-root of the caller.
+
+(4) Processes inside a cgroupns can move in-and-out of the cgroupns-root
+    (if they have proper access to external cgroups).
+    # From inside cgroupns (with cgroupns-root at /batchjobs/container_id1), and
+    # assuming that the global hierarchy is still accessible inside cgroupns:
+    $ cat /proc/7353/cgroup
+    0:cpuset,cpu,cpuacct,memory,devices,freezer,hugetlb:/sub_cgrp_1
+    $ echo 7353 > batchjobs/container_id2/cgroup.procs
+    $ cat /proc/7353/cgroup
+    0:cpuset,cpu,cpuacct,memory,devices,freezer,hugetlb:/../container_id2
+
+    Note that this kind of setup is not encouraged. A task inside cgroupns
+    should only be exposed to its own cgroupns hierarchy. Otherwise it makes
+    the virtualization of /proc/<pid>/cgroup less useful.
+
+(5) Setns to another cgroup namespace is allowed when:
+    (a) the process has CAP_SYS_ADMIN in its current userns
+    (b) the process has CAP_SYS_ADMIN in the target cgroupns' userns
+    No implicit cgroup changes happen with attaching to another cgroupns. It
+    is expected that the somone moves the attaching process under the target
+    cgroupns-root.
+
+(6) When some thread from a multi-threaded process unshares its
+    cgroup-namespace, the new cgroupns gets applied to the entire process (all
+    the threads). For the unified-hierarchy this is expected as it only allows
+    process-level containerization.  For the legacy hierarchies this may be
+    unexpected.  So all the threads in the process will have the same cgroup.
+
+(7) The cgroup namespace is alive as long as there is atleast 1
+    process inside it. When the last process exits, the cgroup
+    namespace is destroyed. The cgroupns-root and the actual cgroups
+    remain though.
+
+(8) Namespace specific cgroup hierarchy can be mounted by a process running
+    inside cgroupns:
+    $ mount -t cgroup -o __DEVEL__sane_behavior cgroup $MOUNT_POINT
+
+    This will mount the unified cgroup hierarchy with cgroupns-root as the
+    filesystem root. The process needs CAP_SYS_ADMIN in its userns and mntns.

+Broadcom BCM283x Camera Interface (Unicam)
+------------------------------------------
+
+The Unicam block on BCM283x SoCs is the receiver for either
+CSI-2 or CCP2 data from image sensors or similar devices.
+
+The main platform using this SoC is the Raspberry Pi family of boards.
+On the Pi the VideoCore firmware can also control this hardware block,
+and driving it from two different processors will cause issues.
+To avoid this, the firmware checks the device tree configuration
+during boot. If it finds device tree nodes called csi0 or csi1 then
+it will stop the firmware accessing the block, and it can then
+safely be used via the device tree binding.
+
+Required properties:
+===================
+- compatible	: must be "brcm,bcm2835-unicam".
+- reg		: physical base address and length of the register sets for the
+		  device.
+- interrupts	: should contain the IRQ line for this Unicam instance.
+- clocks	: list of clock specifiers, corresponding to entries in
+		  clock-names property.
+- clock-names	: must contain "lp" and "vpu" entries, matching entries in the
+		  clocks property.
+
+Unicam supports a single port node. It should contain one 'port' child node
+with child 'endpoint' node. Please refer to the bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Within the endpoint node the "remote-endpoint" and "data-lanes" properties
+are mandatory.
+Data lane reordering is not supported so the data lanes must be in order,
+starting at 1. The number of data lanes should represent the number of
+usable lanes for the hardware block. That may be limited by either the SoC or
+how the platform presents the interface, and the lower value must be used.
+
+Lane reordering is not supported on the clock lane either, so the optional
+property "clock-lane" will implicitly be <0>.
+Similarly lane inversion is not supported, therefore "lane-polarities" will
+implicitly be <0 0 0 0 0>.
+Neither of these values will be checked.
+
+Example:
+	csi1: csi1@7e801000 {
+		compatible = "brcm,bcm2835-unicam";
+		reg = <0x7e801000 0x800>,
+		      <0x7e802004 0x4>;
+		interrupts = <2 7>;
+		clocks = <&clocks BCM2835_CLOCK_CAM1>,
+			 <&firmware_clocks 4>;
+		clock-names = "lp", "vpu";
+		port {
+			csi1_ep: endpoint {
+				remote-endpoint = <&tc358743_0>;
+				data-lanes = <1 2>;
+			};
+		};
+	};
+
+	i2c0: i2c@7e205000 {
+		tc358743: csi-hdmi-bridge@0f {
+			compatible = "toshiba,tc358743";
+			reg = <0x0f>;
+
+			clocks = <&tc358743_clk>;
+			clock-names = "refclk";
+
+			tc358743_clk: bridge-clk {
+				compatible = "fixed-clock";
+				#clock-cells = <0>;
+				clock-frequency = <27000000>;
+			};
+
+			port {
+				tc358743_0: endpoint {
+					remote-endpoint = <&csi1_ep>;
+					clock-lanes = <0>;
+					data-lanes = <1 2>;
+					clock-noncontinuous;
+					link-frequencies =
+						/bits/ 64 <297000000>;
+				};
+			};
+		};

-- rotation: The device, typically an image sensor, is not mounted upright,
-  but a number of degrees counter clockwise. Typical values are 0 and 180
-  (upside down).
+- rotation: The camera rotation is expressed as the angular difference in
+  degrees between two reference systems, one relative to the camera module, and
+  one defined on the external world scene to be captured when projected on the
+  image sensor pixel array.
 
+  A camera sensor has a 2-dimensional reference system 'Rc' defined by
+  its pixel array read-out order. The origin is set to the first pixel
+  being read out, the X-axis points along the column read-out direction
+  towards the last columns, and the Y-axis along the row read-out
+  direction towards the last row.
+
+  A typical example for a sensor with a 2592x1944 pixel array matrix
+  observed from the front is:
+
+              2591       X-axis          0

+
+  The external world scene reference system 'Rs' is a 2-dimensional
+  reference system on the focal plane of the camera module. The origin is
+  placed on the top-left corner of the visible scene, the X-axis points
+  towards the right, and the Y-axis points towards the bottom of the
+  scene. The top, bottom, left and right directions are intentionally not
+  defined and depend on the environment in which the camera is used.
+
+  A typical example of a (very common) picture of a shark swimming from
+  left to right, as seen from the camera, is:

+               0               X-axis

+
+  When projected on the sensor's pixel array, the image and the associated
+  reference system 'Rs' are typically (but not always) inverted, due to
+  the camera module's lens optical inversion effect.
+
+  Assuming the above represented scene of the swimming shark, the lens
+  inversion projects the scene and its reference system onto the sensor
+  pixel array, seen from the front of the camera sensor, as follows:
+
+            Y-axis
+               ^
+               !
+               !

+               0               X-axis
+
+  Note the shark being upside-down.
+
+  The resulting projected reference system is named 'Rp'.
+
+  The camera rotation property is then defined as the angular difference
+  in the counter-clockwise direction between the camera reference system
+  'Rc' and the projected scene reference system 'Rp'. It is expressed in
+  degrees as a number in the range [0, 360[.

+  Example two - Phone camera
+
+  A camera installed on the back side of a mobile device facing away from
+  the user. The captured images are meant to be displayed in portrait mode
+  (height > width) to match the device screen orientation and the device
+  usage orientation used when taking the picture.
+
+  The camera sensor is typically mounted with its pixel array longer side
+  aligned to the device longer side, upside-down mounted to compensate for
+  the lens optical inversion effect:

+
+  The two reference systems are not aligned and the 'Rp' reference
+  system is rotated by 90 degrees in the counter-clockwise direction
+  relatively to the 'Rc' reference system.

+  system where the device is installed on.
+  Possible values are:
+  0 - Front. The device is mounted on the front facing side of the system.
+  For mobile devices such as smartphones, tablets and laptops the front side is
+  the user facing side.
+  1 - Back. The device is mounted on the back side of the system, which is
+  defined as the opposite side of the front facing one.
+  2 - External. The device is not attached directly to the system but is
+  attached in a way that allows it to move freely.

+
+- reg -- the register start address and length for the PCIe reg block.
+- interrupts -- two interrupts are specified; the first interrupt is for
+     the PCI host controller and the second is for MSI if the built-in
+     MSI controller is to be used.
+- interrupt-names -- names of the interrupts (above): "pcie" and "msi".
+- #address-cells -- set to <3>.
+- #size-cells -- set to <2>.
+- #interrupt-cells: set to <1>.
+- interrupt-map-mask and interrupt-map, standard PCI properties to define the

+- ranges: ranges for the PCI memory and I/O regions.
+- linux,pci-domain -- should be unique per host controller.
+
+Optional Properties:
+- clocks -- phandle of pcie clock.
+- clock-names -- set to "sw_pcie" if clocks is used.
+- dma-ranges -- Specifies the inbound memory mapping regions when
+     an "identity map" is not possible.
+- msi-controller -- this property is typically specified to have the

+Howto use the configfs overlay interface.
+
+A device-tree configfs entry is created in /config/device-tree/overlays
+and and it is manipulated using standard file system I/O.
+Note that this is a debug level interface, for use by developers and
+not necessarily something accessed by normal users due to the
+security implications of having direct access to the kernel's device tree.
+
+* To create an overlay you mkdir the directory:
+
+	# mkdir /config/device-tree/overlays/foo
+
+* Either you echo the overlay firmware file to the path property file.
+
+	# echo foo.dtbo >/config/device-tree/overlays/foo/path
+
+* Or you cat the contents of the overlay to the dtbo file
+
+	# cat foo.dtbo >/config/device-tree/overlays/foo/dtbo
+
+The overlay file will be applied, and devices will be created/destroyed
+as required.
+
+To remove it simply rmdir the directory.
+
+	# rmdir /config/device-tree/overlays/foo
+
+The rationalle of the dual interface (firmware & direct copy) is that each is
+better suited to different use patterns. The firmware interface is what's
+intended to be used by hardware managers in the kernel, while the copy interface
+make sense for developers (since it avoids problems with namespaces).

+Aufs5 -- advanced multi layered unification filesystem version 5.x
+http://aufs.sf.net
+Junjiro R. Okajima
+
+
+0. Introduction
+----------------------------------------
+In the early days, aufs was entirely re-designed and re-implemented
+Unionfs Version 1.x series. Adding many original ideas, approaches,
+improvements and implementations, it became totally different from
+Unionfs while keeping the basic features.
+Later, Unionfs Version 2.x series began taking some of the same
+approaches to aufs1's.
+Unionfs was being developed by Professor Erez Zadok at Stony Brook
+University and his team.
+
+Aufs5 supports linux-v5.0 and later, If you want older kernel version
+support,
+- for linux-v4.x series, try aufs4-linux.git or aufs4-standalone.git
+- for linux-v3.x series, try aufs3-linux.git or aufs3-standalone.git
+- for linux-v2.6.16 and later, try aufs2-2.6.git, aufs2-standalone.git
+  or aufs1 from CVS on SourceForge.
+
+Note: it becomes clear that "Aufs was rejected. Let's give it up."
+      According to Christoph Hellwig, linux rejects all union-type
+      filesystems but UnionMount.
+<http://marc.info/?l=linux-kernel&m=123938533724484&w=2>
+
+PS. Al Viro seems have a plan to merge aufs as well as overlayfs and
+    UnionMount, and he pointed out an issue around a directory mutex
+    lock and aufs addressed it. But it is still unsure whether aufs will
+    be merged (or any other union solution).
+<http://marc.info/?l=linux-kernel&m=136312705029295&w=1>
+
+
+1. Features
+----------------------------------------
+- unite several directories into a single virtual filesystem. The member
+  directory is called as a branch.
+- you can specify the permission flags to the branch, which are 'readonly',
+  'readwrite' and 'whiteout-able.'
+- by upper writable branch, internal copyup and whiteout, files/dirs on
+  readonly branch are modifiable logically.
+- dynamic branch manipulation, add, del.
+- etc...
+
+Also there are many enhancements in aufs, such as:
+- test only the highest one for the directory permission (dirperm1)
+- copyup on open (coo=)
+- 'move' policy for copy-up between two writable branches, after
+  checking free space.
+- xattr, acl
+- readdir(3) in userspace.
+- keep inode number by external inode number table
+- keep the timestamps of file/dir in internal copyup operation
+- seekable directory, supporting NFS readdir.
+- whiteout is hardlinked in order to reduce the consumption of inodes
+  on branch
+- do not copyup, nor create a whiteout when it is unnecessary
+- revert a single systemcall when an error occurs in aufs
+- remount interface instead of ioctl
+- maintain /etc/mtab by an external command, /sbin/mount.aufs.
+- loopback mounted filesystem as a branch
+- kernel thread for removing the dir who has a plenty of whiteouts
+- support copyup sparse file (a file which has a 'hole' in it)
+- default permission flags for branches
+- selectable permission flags for ro branch, whether whiteout can
+  exist or not
+- export via NFS.
+- support <sysfs>/fs/aufs and <debugfs>/aufs.
+- support multiple writable branches, some policies to select one
+  among multiple writable branches.
+- a new semantics for link(2) and rename(2) to support multiple
+  writable branches.
+- no glibc changes are required.
+- pseudo hardlink (hardlink over branches)
+- allow a direct access manually to a file on branch, e.g. bypassing aufs.
+  including NFS or remote filesystem branch.
+- userspace wrapper for pathconf(3)/fpathconf(3) with _PC_LINK_MAX.
+- and more...
+
+Currently these features are dropped temporary from aufs5.
+See design/08plan.txt in detail.
+- nested mount, i.e. aufs as readonly no-whiteout branch of another aufs
+  (robr)
+- statistics of aufs thread (/sys/fs/aufs/stat)
+
+Features or just an idea in the future (see also design/*.txt),
+- reorder the branch index without del/re-add.
+- permanent xino files for NFSD
+- an option for refreshing the opened files after add/del branches
+- light version, without branch manipulation. (unnecessary?)
+- copyup in userspace
+- inotify in userspace
+- readv/writev
+
+
+2. Download
+----------------------------------------
+There are three GIT trees for aufs5, aufs5-linux.git,
+aufs5-standalone.git, and aufs-util.git. Note that there is no "5" in
+"aufs-util.git."
+While the aufs-util is always necessary, you need either of aufs5-linux
+or aufs5-standalone.
+
+The aufs5-linux tree includes the whole linux mainline GIT tree,
+git://git.kernel.org/.../torvalds/linux.git.
+And you cannot select CONFIG_AUFS_FS=m for this version, eg. you cannot
+build aufs5 as an external kernel module.
+Several extra patches are not included in this tree. Only
+aufs5-standalone tree contains them. They are described in the later
+section "Configuration and Compilation."
+
+On the other hand, the aufs5-standalone tree has only aufs source files
+and necessary patches, and you can select CONFIG_AUFS_FS=m.
+But you need to apply all aufs patches manually.
+
+You will find GIT branches whose name is in form of "aufs5.x" where "x"
+represents the linux kernel version, "linux-5.x". For instance,
+"aufs5.0" is for linux-5.0. For latest "linux-5.x-rcN", use
+"aufs5.x-rcN" branch.
+
+o aufs5-linux tree
+$ git clone --reference /your/linux/git/tree \
+	git://github.com/sfjro/aufs5-linux.git aufs5-linux.git
+- if you don't have linux GIT tree, then remove "--reference ..."
+$ cd aufs5-linux.git
+$ git checkout origin/aufs5.0
+
+Or You may want to directly git-pull aufs into your linux GIT tree, and
+leave the patch-work to GIT.
+$ cd /your/linux/git/tree
+$ git remote add aufs5 git://github.com/sfjro/aufs5-linux.git
+$ git fetch aufs5
+$ git checkout -b my5.0 v5.0
+$ (add your local change...)
+$ git pull aufs5 aufs5.0
+- now you have v5.0 + your_changes + aufs5.0 in you my5.0 branch.
+- you may need to solve some conflicts between your_changes and
+  aufs5.0. in this case, git-rerere is recommended so that you can
+  solve the similar conflicts automatically when you upgrade to 5.1 or
+  later in the future.
+
+o aufs5-standalone tree
+$ git clone git://github.com/sfjro/aufs5-standalone.git aufs5-standalone.git
+$ cd aufs5-standalone.git
+$ git checkout origin/aufs5.0
+
+o aufs-util tree
+$ git clone git://git.code.sf.net/p/aufs/aufs-util aufs-util.git
+- note that the public aufs-util.git is on SourceForge instead of
+  GitHUB.
+$ cd aufs-util.git
+$ git checkout origin/aufs5.0
+
+Note: The 5.x-rcN branch is to be used with `rc' kernel versions ONLY.
+The minor version number, 'x' in '5.x', of aufs may not always
+follow the minor version number of the kernel.
+Because changes in the kernel that cause the use of a new
+minor version number do not always require changes to aufs-util.
+
+Since aufs-util has its own minor version number, you may not be
+able to find a GIT branch in aufs-util for your kernel's
+exact minor version number.
+In this case, you should git-checkout the branch for the
+nearest lower number.
+
+For (an unreleased) example:
+If you are using "linux-5.10" and the "aufs5.10" branch
+does not exist in aufs-util repository, then "aufs5.9", "aufs5.8"
+or something numerically smaller is the branch for your kernel.
+
+Also you can view all branches by
+	$ git branch -a
+
+
+3. Configuration and Compilation
+----------------------------------------
+Make sure you have git-checkout'ed the correct branch.
+
+For aufs5-linux tree,
+- enable CONFIG_AUFS_FS.
+- set other aufs configurations if necessary.
+
+For aufs5-standalone tree,
+There are several ways to build.
+
+1.
+- apply ./aufs5-kbuild.patch to your kernel source files.
+- apply ./aufs5-base.patch too.
+- apply ./aufs5-mmap.patch too.
+- apply ./aufs5-standalone.patch too, if you have a plan to set
+  CONFIG_AUFS_FS=m. otherwise you don't need ./aufs5-standalone.patch.
+- copy ./{Documentation,fs,include/uapi/linux/aufs_type.h} files to your
+  kernel source tree. Never copy $PWD/include/uapi/linux/Kbuild.
+- enable CONFIG_AUFS_FS, you can select either
+  =m or =y.
+- and build your kernel as usual.
+- install the built kernel.
+- install the header files too by "make headers_install" to the
+  directory where you specify. By default, it is $PWD/usr.
+  "make help" shows a brief note for headers_install.
+- and reboot your system.
+
+2.
+- module only (CONFIG_AUFS_FS=m).
+- apply ./aufs5-base.patch to your kernel source files.
+- apply ./aufs5-mmap.patch too.
+- apply ./aufs5-standalone.patch too.
+- build your kernel, don't forget "make headers_install", and reboot.
+- edit ./config.mk and set other aufs configurations if necessary.
+  Note: You should read $PWD/fs/aufs/Kconfig carefully which describes
+  every aufs configurations.
+- build the module by simple "make".
+- you can specify ${KDIR} make variable which points to your kernel
+  source tree.
+- install the files
+  + run "make install" to install the aufs module, or copy the built
+    $PWD/aufs.ko to /lib/modules/... and run depmod -a (or reboot simply).
+  + run "make install_headers" (instead of headers_install) to install
+    the modified aufs header file (you can specify DESTDIR which is
+    available in aufs standalone version's Makefile only), or copy
+    $PWD/usr/include/linux/aufs_type.h to /usr/include/linux or wherever
+    you like manually. By default, the target directory is $PWD/usr.
+- no need to apply aufs5-kbuild.patch, nor copying source files to your
+  kernel source tree.
+
+Note: The header file aufs_type.h is necessary to build aufs-util
+      as well as "make headers_install" in the kernel source tree.
+      headers_install is subject to be forgotten, but it is essentially
+      necessary, not only for building aufs-util.
+      You may not meet problems without headers_install in some older
+      version though.
+
+And then,
+- read README in aufs-util, build and install it
+- note that your distribution may contain an obsoleted version of
+  aufs_type.h in /usr/include/linux or something. When you build aufs
+  utilities, make sure that your compiler refers the correct aufs header
+  file which is built by "make headers_install."
+- if you want to use readdir(3) in userspace or pathconf(3) wrapper,
+  then run "make install_ulib" too. And refer to the aufs manual in
+  detail.
+
+There several other patches in aufs5-standalone.git. They are all
+optional. When you meet some problems, they will help you.
+- aufs5-loopback.patch
+  Supports a nested loopback mount in a branch-fs. This patch is
+  unnecessary until aufs produces a message like "you may want to try
+  another patch for loopback file".
+- proc_mounts.patch
+  When there are many mountpoints and many mount(2)/umount(2) are
+  running, then /proc/mounts may not show the all mountpoints.  This
+  patch makes /proc/mounts always show the full mountpoints list.
+  If you don't want to apply this patch and meet such problem, then you
+  need to increase the value of 'ProcMounts_Times' make-variable in
+  aufs-util.git as a second best solution.
+- vfs-ino.patch
+  Modifies a system global kernel internal function get_next_ino() in
+  order to stop assigning 0 for an inode-number. Not directly related to
+  aufs, but recommended generally.
+- tmpfs-idr.patch
+  Keeps the tmpfs inode number as the lowest value. Effective to reduce
+  the size of aufs XINO files for tmpfs branch. Also it prevents the
+  duplication of inode number, which is important for backup tools and
+  other utilities. When you find aufs XINO files for tmpfs branch
+  growing too much, try this patch.
+- lockdep-debug.patch
+  Because aufs is not only an ordinary filesystem (callee of VFS), but
+  also a caller of VFS functions for branch filesystems, subclassing of
+  the internal locks for LOCKDEP is necessary. LOCKDEP is a debugging
+  feature of linux kernel. If you enable CONFIG_LOCKDEP, then you will
+  need to apply this debug patch to expand several constant values.
+  If you don't know what LOCKDEP is, then you don't have apply this
+  patch.
+
+
+4. Usage
+----------------------------------------
+At first, make sure aufs-util are installed, and please read the aufs
+manual, aufs.5 in aufs-util.git tree.
+$ man -l aufs.5
+
+And then,
+$ mkdir /tmp/rw /tmp/aufs
+# mount -t aufs -o br=/tmp/rw:${HOME} none /tmp/aufs
+
+Here is another example. The result is equivalent.
+# mount -t aufs -o br=/tmp/rw=rw:${HOME}=ro none /tmp/aufs
+  Or
+# mount -t aufs -o br:/tmp/rw none /tmp/aufs
+# mount -o remount,append:${HOME} /tmp/aufs
+
+Then, you can see whole tree of your home dir through /tmp/aufs. If
+you modify a file under /tmp/aufs, the one on your home directory is
+not affected, instead the same named file will be newly created under
+/tmp/rw. And all of your modification to a file will be applied to
+the one under /tmp/rw. This is called the file based Copy on Write
+(COW) method.
+Aufs mount options are described in aufs.5.
+If you run chroot or something and make your aufs as a root directory,
+then you need to customize the shutdown script. See the aufs manual in
+detail.
+
+Additionally, there are some sample usages of aufs which are a
+diskless system with network booting, and LiveCD over NFS.
+See sample dir in CVS tree on SourceForge.
+
+
+5. Contact
+----------------------------------------
+When you have any problems or strange behaviour in aufs, please let me
+know with:

+- /sys/module/aufs/*
+- /sys/fs/aufs/* (if you have them)
+- /debug/aufs/* (if you have them)
+- linux kernel version
+  if your kernel is not plain, for example modified by distributor,

+
+AUFS is a filesystem with features:
+- multi layered stackable unification filesystem, the member directory
+  is called as a branch.
+- branch permission and attribute, 'readonly', 'real-readonly',
+  'readwrite', 'whiteout-able', 'link-able whiteout', etc. and their
+  combination.
+- internal "file copy-on-write".
+- logical deletion, whiteout.
+- dynamic branch manipulation, adding, deleting and changing permission.
+- allow bypassing aufs, user's direct branch access.
+- external inode number translation table and bitmap which maintains the
+  persistent aufs inode number.
+- seekable directory, including NFS readdir.
+- file mapping, mmap and sharing pages.
+- pseudo-link, hardlink over branches.
+- loopback mounted filesystem as a branch.
+- several policies to select one among multiple writable branches.
+- revert a single systemcall when an error occurs in aufs.
+- and more...
+
+
+Multi Layered Stackable Unification Filesystem
+----------------------------------------------------------------------
+Most people already knows what it is.
+It is a filesystem which unifies several directories and provides a
+merged single directory. When users access a file, the access will be
+passed/re-directed/converted (sorry, I am not sure which English word is
+correct) to the real file on the member filesystem. The member
+filesystem is called 'lower filesystem' or 'branch' and has a mode
+'readonly' and 'readwrite.' And the deletion for a file on the lower
+readonly branch is handled by creating 'whiteout' on the upper writable
+branch.
+
+On LKML, there have been discussions about UnionMount (Jan Blunck,
+Bharata B Rao and Valerie Aurora) and Unionfs (Erez Zadok). They took
+different approaches to implement the merged-view.
+The former tries putting it into VFS, and the latter implements as a
+separate filesystem.
+(If I misunderstand about these implementations, please let me know and
+I shall correct it. Because it is a long time ago when I read their
+source files last time).
+
+UnionMount's approach will be able to small, but may be hard to share
+branches between several UnionMount since the whiteout in it is
+implemented in the inode on branch filesystem and always
+shared. According to Bharata's post, readdir does not seems to be
+finished yet.
+There are several missing features known in this implementations such as
+- for users, the inode number may change silently. eg. copy-up.
+- link(2) may break by copy-up.
+- read(2) may get an obsoleted filedata (fstat(2) too).
+- fcntl(F_SETLK) may be broken by copy-up.
+- unnecessary copy-up may happen, for example mmap(MAP_PRIVATE) after
+  open(O_RDWR).
+
+In linux-3.18, "overlay" filesystem (formerly known as "overlayfs") was
+merged into mainline. This is another implementation of UnionMount as a
+separated filesystem. All the limitations and known problems which
+UnionMount are equally inherited to "overlay" filesystem.
+
+Unionfs has a longer history. When I started implementing a stackable
+filesystem (Aug 2005), it already existed. It has virtual super_block,
+inode, dentry and file objects and they have an array pointing lower
+same kind objects. After contributing many patches for Unionfs, I
+re-started my project AUFS (Jun 2006).
+
+In AUFS, the structure of filesystem resembles to Unionfs, but I
+implemented my own ideas, approaches and enhancements and it became
+totally different one.
+
+Comparing DM snapshot and fs based implementation
+- the number of bytes to be copied between devices is much smaller.
+- the type of filesystem must be one and only.
+- the fs must be writable, no readonly fs, even for the lower original
+  device. so the compression fs will not be usable. but if we use
+  loopback mount, we may address this issue.
+  for instance,
+	mount /cdrom/squashfs.img /sq
+	losetup /sq/ext2.img
+	losetup /somewhere/cow
+	dmsetup "snapshot /dev/loop0 /dev/loop1 ..."
+- it will be difficult (or needs more operations) to extract the
+  difference between the original device and COW.
+- DM snapshot-merge may help a lot when users try merging. in the
+  fs-layer union, users will use rsync(1).
+
+You may want to read my old paper "Filesystems in LiveCD"
+(http://aufs.sourceforge.net/aufs2/report/sq/sq.pdf).
+
+
+Several characters/aspects/persona of aufs
+----------------------------------------------------------------------
+
+Aufs has several characters, aspects or persona.
+1. a filesystem, callee of VFS helper
+2. sub-VFS, caller of VFS helper for branches
+3. a virtual filesystem which maintains persistent inode number
+4. reader/writer of files on branches such like an application
+
+1. Callee of VFS Helper
+As an ordinary linux filesystem, aufs is a callee of VFS. For instance,
+unlink(2) from an application reaches sys_unlink() kernel function and
+then vfs_unlink() is called. vfs_unlink() is one of VFS helper and it
+calls filesystem specific unlink operation. Actually aufs implements the
+unlink operation but it behaves like a redirector.
+
+2. Caller of VFS Helper for Branches
+aufs_unlink() passes the unlink request to the branch filesystem as if
+it were called from VFS. So the called unlink operation of the branch
+filesystem acts as usual. As a caller of VFS helper, aufs should handle
+every necessary pre/post operation for the branch filesystem.
+- acquire the lock for the parent dir on a branch
+- lookup in a branch
+- revalidate dentry on a branch
+- mnt_want_write() for a branch
+- vfs_unlink() for a branch
+- mnt_drop_write() for a branch
+- release the lock on a branch
+
+3. Persistent Inode Number
+One of the most important issue for a filesystem is to maintain inode
+numbers. This is particularly important to support exporting a
+filesystem via NFS. Aufs is a virtual filesystem which doesn't have a
+backend block device for its own. But some storage is necessary to
+keep and maintain the inode numbers. It may be a large space and may not
+suit to keep in memory. Aufs rents some space from its first writable
+branch filesystem (by default) and creates file(s) on it. These files
+are created by aufs internally and removed soon (currently) keeping
+opened.
+Note: Because these files are removed, they are totally gone after
+      unmounting aufs. It means the inode numbers are not persistent
+      across unmount or reboot. I have a plan to make them really
+      persistent which will be important for aufs on NFS server.
+
+4. Read/Write Files Internally (copy-on-write)
+Because a branch can be readonly, when you write a file on it, aufs will
+"copy-up" it to the upper writable branch internally. And then write the
+originally requested thing to the file. Generally kernel doesn't
+open/read/write file actively. In aufs, even a single write may cause a
+internal "file copy". This behaviour is very similar to cp(1) command.
+
+Some people may think it is better to pass such work to user space
+helper, instead of doing in kernel space. Actually I am still thinking
+about it. But currently I have implemented it in kernel space.

+
+Basic Aufs Internal Structure
+
+Superblock/Inode/Dentry/File Objects
+----------------------------------------------------------------------
+As like an ordinary filesystem, aufs has its own
+superblock/inode/dentry/file objects. All these objects have a
+dynamically allocated array and store the same kind of pointers to the
+lower filesystem, branch.
+For example, when you build a union with one readwrite branch and one
+readonly, mounted /au, /rw and /ro respectively.
+- /au = /rw + /ro
+- /ro/fileA exists but /rw/fileA
+
+Aufs lookup operation finds /ro/fileA and gets dentry for that. These
+pointers are stored in a aufs dentry. The array in aufs dentry will be,
+- [0] = NULL (because /rw/fileA doesn't exist)
+- [1] = /ro/fileA
+
+This style of an array is essentially same to the aufs
+superblock/inode/dentry/file objects.
+
+Because aufs supports manipulating branches, ie. add/delete/change
+branches dynamically, these objects has its own generation. When
+branches are changed, the generation in aufs superblock is
+incremented. And a generation in other object are compared when it is
+accessed. When a generation in other objects are obsoleted, aufs
+refreshes the internal array.
+
+
+Superblock
+----------------------------------------------------------------------
+Additionally aufs superblock has some data for policies to select one
+among multiple writable branches, XIB files, pseudo-links and kobject.
+See below in detail.
+About the policies which supports copy-down a directory, see
+wbr_policy.txt too.
+
+
+Branch and XINO(External Inode Number Translation Table)
+----------------------------------------------------------------------
+Every branch has its own xino (external inode number translation table)
+file. The xino file is created and unlinked by aufs internally. When two
+members of a union exist on the same filesystem, they share the single
+xino file.
+The struct of a xino file is simple, just a sequence of aufs inode
+numbers which is indexed by the lower inode number.
+In the above sample, assume the inode number of /ro/fileA is i111 and
+aufs assigns the inode number i999 for fileA. Then aufs writes 999 as
+4(8) bytes at 111 * 4(8) bytes offset in the xino file.
+
+When the inode numbers are not contiguous, the xino file will be sparse
+which has a hole in it and doesn't consume as much disk space as it
+might appear. If your branch filesystem consumes disk space for such
+holes, then you should specify 'xino=' option at mounting aufs.
+
+Aufs has a mount option to free the disk blocks for such holes in XINO
+files on tmpfs or ramdisk. But it is not so effective actually. If you
+meet a problem of disk shortage due to XINO files, then you should try
+"tmpfs-ino.patch" (and "vfs-ino.patch" too) in aufs4-standalone.git.
+The patch localizes the assignment inumbers per tmpfs-mount and avoid
+the holes in XINO files.
+
+Also a writable branch has three kinds of "whiteout bases". All these
+are existed when the branch is joined to aufs, and their names are
+whiteout-ed doubly, so that users will never see their names in aufs
+hierarchy.
+1. a regular file which will be hardlinked to all whiteouts.
+2. a directory to store a pseudo-link.
+3. a directory to store an "orphan"-ed file temporary.
+
+1. Whiteout Base
+   When you remove a file on a readonly branch, aufs handles it as a
+   logical deletion and creates a whiteout on the upper writable branch
+   as a hardlink of this file in order not to consume inode on the
+   writable branch.
+2. Pseudo-link Dir
+   See below, Pseudo-link.
+3. Step-Parent Dir
+   When "fileC" exists on the lower readonly branch only and it is
+   opened and removed with its parent dir, and then user writes
+   something into it, then aufs copies-up fileC to this
+   directory. Because there is no other dir to store fileC. After
+   creating a file under this dir, the file is unlinked.
+
+Because aufs supports manipulating branches, ie. add/delete/change
+dynamically, a branch has its own id. When the branch order changes,
+aufs finds the new index by searching the branch id.
+
+
+Pseudo-link
+----------------------------------------------------------------------
+Assume "fileA" exists on the lower readonly branch only and it is
+hardlinked to "fileB" on the branch. When you write something to fileA,
+aufs copies-up it to the upper writable branch. Additionally aufs
+creates a hardlink under the Pseudo-link Directory of the writable
+branch. The inode of a pseudo-link is kept in aufs super_block as a
+simple list. If fileB is read after unlinking fileA, aufs returns
+filedata from the pseudo-link instead of the lower readonly
+branch. Because the pseudo-link is based upon the inode, to keep the
+inode number by xino (see above) is essentially necessary.
+
+All the hardlinks under the Pseudo-link Directory of the writable branch
+should be restored in a proper location later. Aufs provides a utility
+to do this. The userspace helpers executed at remounting and unmounting
+aufs by default.
+During this utility is running, it puts aufs into the pseudo-link
+maintenance mode. In this mode, only the process which began the
+maintenance mode (and its child processes) is allowed to operate in
+aufs. Some other processes which are not related to the pseudo-link will
+be allowed to run too, but the rest have to return an error or wait
+until the maintenance mode ends. If a process already acquires an inode
+mutex (in VFS), it has to return an error.
+
+
+XIB(external inode number bitmap)
+----------------------------------------------------------------------
+Addition to the xino file per a branch, aufs has an external inode number
+bitmap in a superblock object. It is also an internal file such like a
+xino file.
+It is a simple bitmap to mark whether the aufs inode number is in-use or
+not.
+To reduce the file I/O, aufs prepares a single memory page to cache xib.
+
+As well as XINO files, aufs has a feature to truncate/refresh XIB to
+reduce the number of consumed disk blocks for these files.
+
+
+Virtual or Vertical Dir, and Readdir in Userspace
+----------------------------------------------------------------------
+In order to support multiple layers (branches), aufs readdir operation
+constructs a virtual dir block on memory. For readdir, aufs calls
+vfs_readdir() internally for each dir on branches, merges their entries
+with eliminating the whiteout-ed ones, and sets it to file (dir)
+object. So the file object has its entry list until it is closed. The
+entry list will be updated when the file position is zero and becomes
+obsoleted. This decision is made in aufs automatically.
+
+The dynamically allocated memory block for the name of entries has a
+unit of 512 bytes (by default) and stores the names contiguously (no
+padding). Another block for each entry is handled by kmem_cache too.
+During building dir blocks, aufs creates hash list and judging whether
+the entry is whiteouted by its upper branch or already listed.
+The merged result is cached in the corresponding inode object and
+maintained by a customizable life-time option.
+
+Some people may call it can be a security hole or invite DoS attack
+since the opened and once readdir-ed dir (file object) holds its entry
+list and becomes a pressure for system memory. But I'd say it is similar
+to files under /proc or /sys. The virtual files in them also holds a
+memory page (generally) while they are opened. When an idea to reduce
+memory for them is introduced, it will be applied to aufs too.
+For those who really hate this situation, I've developed readdir(3)
+library which operates this merging in userspace. You just need to set
+LD_PRELOAD environment variable, and aufs will not consume no memory in
+kernel space for readdir(3).
+
+
+Workqueue
+----------------------------------------------------------------------
+Aufs sometimes requires privilege access to a branch. For instance,
+in copy-up/down operation. When a user process is going to make changes
+to a file which exists in the lower readonly branch only, and the mode
+of one of ancestor directories may not be writable by a user
+process. Here aufs copy-up the file with its ancestors and they may
+require privilege to set its owner/group/mode/etc.
+This is a typical case of a application character of aufs (see
+Introduction).
+
+Aufs uses workqueue synchronously for this case. It creates its own
+workqueue. The workqueue is a kernel thread and has privilege. Aufs
+passes the request to call mkdir or write (for example), and wait for
+its completion. This approach solves a problem of a signal handler
+simply.
+If aufs didn't adopt the workqueue and changed the privilege of the
+process, then the process may receive the unexpected SIGXFSZ or other
+signals.
+
+Also aufs uses the system global workqueue ("events" kernel thread) too
+for asynchronous tasks, such like handling inotify/fsnotify, re-creating a
+whiteout base and etc. This is unrelated to a privilege.
+Most of aufs operation tries acquiring a rw_semaphore for aufs
+superblock at the beginning, at the same time waits for the completion
+of all queued asynchronous tasks.
+
+
+Whiteout
+----------------------------------------------------------------------
+The whiteout in aufs is very similar to Unionfs's. That is represented
+by its filename. UnionMount takes an approach of a file mode, but I am
+afraid several utilities (find(1) or something) will have to support it.
+
+Basically the whiteout represents "logical deletion" which stops aufs to
+lookup further, but also it represents "dir is opaque" which also stop
+further lookup.
+
+In aufs, rmdir(2) and rename(2) for dir uses whiteout alternatively.
+In order to make several functions in a single systemcall to be
+revertible, aufs adopts an approach to rename a directory to a temporary
+unique whiteouted name.
+For example, in rename(2) dir where the target dir already existed, aufs
+renames the target dir to a temporary unique whiteouted name before the
+actual rename on a branch, and then handles other actions (make it opaque,
+update the attributes, etc). If an error happens in these actions, aufs
+simply renames the whiteouted name back and returns an error. If all are
+succeeded, aufs registers a function to remove the whiteouted unique
+temporary name completely and asynchronously to the system global
+workqueue.
+
+
+Copy-up
+----------------------------------------------------------------------
+It is a well-known feature or concept.
+When user modifies a file on a readonly branch, aufs operate "copy-up"
+internally and makes change to the new file on the upper writable branch.
+When the trigger systemcall does not update the timestamps of the parent
+dir, aufs reverts it after copy-up.
+
+
+Move-down (aufs3.9 and later)
+----------------------------------------------------------------------
+"Copy-up" is one of the essential feature in aufs. It copies a file from
+the lower readonly branch to the upper writable branch when a user
+changes something about the file.
+"Move-down" is an opposite action of copy-up. Basically this action is
+ran manually instead of automatically and internally.
+For desgin and implementation, aufs has to consider these issues.
+- whiteout for the file may exist on the lower branch.
+- ancestor directories may not exist on the lower branch.
+- diropq for the ancestor directories may exist on the upper branch.
+- free space on the lower branch will reduce.
+- another access to the file may happen during moving-down, including
+  UDBA (see "Revalidate Dentry and UDBA").
+- the file should not be hard-linked nor pseudo-linked. they should be
+  handled by auplink utility later.
+
+Sometimes users want to move-down a file from the upper writable branch
+to the lower readonly or writable branch. For instance,
+- the free space of the upper writable branch is going to run out.
+- create a new intermediate branch between the upper and lower branch.
+- etc.
+
+For this purpose, use "aumvdown" command in aufs-util.git.

+
+Support for a branch who has its ->atomic_open()
+----------------------------------------------------------------------
+The filesystems who implement its ->atomic_open() are not majority. For
+example NFSv4 does, and aufs should call NFSv4 ->atomic_open,
+particularly for open(O_CREAT|O_EXCL, 0400) case. Other than
+->atomic_open(), NFSv4 returns an error for this open(2). While I am not
+sure whether all filesystems who have ->atomic_open() behave like this,
+but NFSv4 surely returns the error.
+
+In order to support ->atomic_open() for aufs, there are a few
+approaches.
+
+A. Introduce aufs_atomic_open()
+   - calls one of VFS:do_last(), lookup_open() or atomic_open() for
+     branch fs.
+B. Introduce aufs_atomic_open() calling create, open and chmod. this is
+   an aufs user Pip Cet's approach
+   - calls aufs_create(), VFS finish_open() and notify_change().
+   - pass fake-mode to finish_open(), and then correct the mode by
+     notify_change().
+C. Extend aufs_open() to call branch fs's ->atomic_open()
+   - no aufs_atomic_open().
+   - aufs_lookup() registers the TID to an aufs internal object.
+   - aufs_create() does nothing when the matching TID is registered, but
+     registers the mode.
+   - aufs_open() calls branch fs's ->atomic_open() when the matching
+     TID is registered.
+D. Extend aufs_open() to re-try branch fs's ->open() with superuser's
+   credential
+   - no aufs_atomic_open().
+   - aufs_create() registers the TID to an internal object. this info
+     represents "this process created this file just now."
+   - when aufs gets EACCES from branch fs's ->open(), then confirm the
+     registered TID and re-try open() with superuser's credential.
+
+Pros and cons for each approach.
+
+A.
+   - straightforward but highly depends upon VFS internal.
+   - the atomic behavaiour is kept.
+   - some of parameters such as nameidata are hard to reproduce for
+     branch fs.
+   - large overhead.
+B.
+   - easy to implement.
+   - the atomic behavaiour is lost.
+C.
+   - the atomic behavaiour is kept.
+   - dirty and tricky.
+   - VFS checks whether the file is created correctly after calling
+     ->create(), which means this approach doesn't work.
+D.
+   - easy to implement.
+   - the atomic behavaiour is lost.
+   - to open a file with superuser's credential and give it to a user
+     process is a bad idea, since the file object keeps the credential
+     in it. It may affect LSM or something. This approach doesn't work
+     either.
+
+The approach A is ideal, but it hard to implement. So here is a
+variation of A, which is to be implemented.
+
+A-1. Introduce aufs_atomic_open()
+     - calls branch fs ->atomic_open() if exists. otherwise calls
+       vfs_create() and finish_open().
+     - the demerit is that the several checks after branch fs
+       ->atomic_open() are lost. in the ordinary case, the checks are
+       done by VFS:do_last(), lookup_open() and atomic_open(). some can
+       be implemented in aufs, but not all I am afraid.

+
+Lookup in a Branch
+----------------------------------------------------------------------
+Since aufs has a character of sub-VFS (see Introduction), it operates
+lookup for branches as VFS does. It may be a heavy work. But almost all
+lookup operation in aufs is the simplest case, ie. lookup only an entry
+directly connected to its parent. Digging down the directory hierarchy
+is unnecessary. VFS has a function lookup_one_len() for that use, and
+aufs calls it.
+
+When a branch is a remote filesystem, aufs basically relies upon its
+->d_revalidate(), also aufs forces the hardest revalidate tests for
+them.
+For d_revalidate, aufs implements three levels of revalidate tests. See
+"Revalidate Dentry and UDBA" in detail.
+
+
+Test Only the Highest One for the Directory Permission (dirperm1 option)
+----------------------------------------------------------------------
+Let's try case study.
+- aufs has two branches, upper readwrite and lower readonly.
+  /au = /rw + /ro
+- "dirA" exists under /ro, but /rw. and its mode is 0700.
+- user invoked "chmod a+rx /au/dirA"
+- the internal copy-up is activated and "/rw/dirA" is created and its
+  permission bits are set to world readable.
+- then "/au/dirA" becomes world readable?
+
+In this case, /ro/dirA is still 0700 since it exists in readonly branch,
+or it may be a natively readonly filesystem. If aufs respects the lower
+branch, it should not respond readdir request from other users. But user
+allowed it by chmod. Should really aufs rejects showing the entries
+under /ro/dirA?
+
+To be honest, I don't have a good solution for this case. So aufs
+implements 'dirperm1' and 'nodirperm1' mount options, and leave it to
+users.
+When dirperm1 is specified, aufs checks only the highest one for the
+directory permission, and shows the entries. Otherwise, as usual, checks
+every dir existing on all branches and rejects the request.
+
+As a side effect, dirperm1 option improves the performance of aufs
+because the number of permission check is reduced when the number of
+branch is many.
+
+
+Revalidate Dentry and UDBA (User's Direct Branch Access)
+----------------------------------------------------------------------
+Generally VFS helpers re-validate a dentry as a part of lookup.
+0. digging down the directory hierarchy.
+1. lock the parent dir by its i_mutex.
+2. lookup the final (child) entry.
+3. revalidate it.
+4. call the actual operation (create, unlink, etc.)
+5. unlock the parent dir
+
+If the filesystem implements its ->d_revalidate() (step 3), then it is
+called. Actually aufs implements it and checks the dentry on a branch is
+still valid.
+But it is not enough. Because aufs has to release the lock for the
+parent dir on a branch at the end of ->lookup() (step 2) and
+->d_revalidate() (step 3) while the i_mutex of the aufs dir is still
+held by VFS.
+If the file on a branch is changed directly, eg. bypassing aufs, after
+aufs released the lock, then the subsequent operation may cause
+something unpleasant result.
+
+This situation is a result of VFS architecture, ->lookup() and
+->d_revalidate() is separated. But I never say it is wrong. It is a good
+design from VFS's point of view. It is just not suitable for sub-VFS
+character in aufs.
+
+Aufs supports such case by three level of revalidation which is
+selectable by user.
+1. Simple Revalidate
+   Addition to the native flow in VFS's, confirm the child-parent
+   relationship on the branch just after locking the parent dir on the
+   branch in the "actual operation" (step 4). When this validation
+   fails, aufs returns EBUSY. ->d_revalidate() (step 3) in aufs still
+   checks the validation of the dentry on branches.
+2. Monitor Changes Internally by Inotify/Fsnotify
+   Addition to above, in the "actual operation" (step 4) aufs re-lookup
+   the dentry on the branch, and returns EBUSY if it finds different
+   dentry.
+   Additionally, aufs sets the inotify/fsnotify watch for every dir on branches
+   during it is in cache. When the event is notified, aufs registers a
+   function to kernel 'events' thread by schedule_work(). And the
+   function sets some special status to the cached aufs dentry and inode
+   private data. If they are not cached, then aufs has nothing to
+   do. When the same file is accessed through aufs (step 0-3) later,
+   aufs will detect the status and refresh all necessary data.
+   In this mode, aufs has to ignore the event which is fired by aufs
+   itself.
+3. No Extra Validation
+   This is the simplest test and doesn't add any additional revalidation
+   test, and skip the revalidation in step 4. It is useful and improves
+   aufs performance when system surely hide the aufs branches from user,
+   by over-mounting something (or another method).

+
+Branch Manipulation
+
+Since aufs supports dynamic branch manipulation, ie. add/remove a branch
+and changing its permission/attribute, there are a lot of works to do.
+
+
+Add a Branch
+----------------------------------------------------------------------
+o Confirm the adding dir exists outside of aufs, including loopback
+  mount, and its various attributes.
+o Initialize the xino file and whiteout bases if necessary.
+  See struct.txt.
+
+o Check the owner/group/mode of the directory
+  When the owner/group/mode of the adding directory differs from the
+  existing branch, aufs issues a warning because it may impose a
+  security risk.
+  For example, when a upper writable branch has a world writable empty
+  top directory, a malicious user can create any files on the writable
+  branch directly, like copy-up and modify manually. If something like
+  /etc/{passwd,shadow} exists on the lower readonly branch but the upper
+  writable branch, and the writable branch is world-writable, then a
+  malicious guy may create /etc/passwd on the writable branch directly
+  and the infected file will be valid in aufs.
+  I am afraid it can be a security issue, but aufs can do nothing except
+  producing a warning.
+
+
+Delete a Branch
+----------------------------------------------------------------------
+o Confirm the deleting branch is not busy
+  To be general, there is one merit to adopt "remount" interface to
+  manipulate branches. It is to discard caches. At deleting a branch,
+  aufs checks the still cached (and connected) dentries and inodes. If
+  there are any, then they are all in-use. An inode without its
+  corresponding dentry can be alive alone (for example, inotify/fsnotify case).
+
+  For the cached one, aufs checks whether the same named entry exists on
+  other branches.
+  If the cached one is a directory, because aufs provides a merged view
+  to users, as long as one dir is left on any branch aufs can show the
+  dir to users. In this case, the branch can be removed from aufs.
+  Otherwise aufs rejects deleting the branch.
+
+  If any file on the deleting branch is opened by aufs, then aufs
+  rejects deleting.
+
+
+Modify the Permission of a Branch
+----------------------------------------------------------------------
+o Re-initialize or remove the xino file and whiteout bases if necessary.
+  See struct.txt.
+
+o rw --> ro: Confirm the modifying branch is not busy
+  Aufs rejects the request if any of these conditions are true.
+  - a file on the branch is mmap-ed.
+  - a regular file on the branch is opened for write and there is no
+    same named entry on the upper branch.

+
+Policies to Select One among Multiple Writable Branches
+----------------------------------------------------------------------
+When the number of writable branch is more than one, aufs has to decide
+the target branch for file creation or copy-up. By default, the highest
+writable branch which has the parent (or ancestor) dir of the target
+file is chosen (top-down-parent policy).
+By user's request, aufs implements some other policies to select the
+writable branch, for file creation several policies, round-robin,
+most-free-space, and other policies. For copy-up, top-down-parent,
+bottom-up-parent, bottom-up and others.
+
+As expected, the round-robin policy selects the branch in circular. When
+you have two writable branches and creates 10 new files, 5 files will be
+created for each branch. mkdir(2) systemcall is an exception. When you
+create 10 new directories, all will be created on the same branch.
+And the most-free-space policy selects the one which has most free
+space among the writable branches. The amount of free space will be
+checked by aufs internally, and users can specify its time interval.
+
+The policies for copy-up is more simple,
+top-down-parent is equivalent to the same named on in create policy,
+bottom-up-parent selects the writable branch where the parent dir
+exists and the nearest upper one from the copyup-source,
+bottom-up selects the nearest upper writable branch from the
+copyup-source, regardless the existence of the parent dir.
+
+There are some rules or exceptions to apply these policies.
+- If there is a readonly branch above the policy-selected branch and
+  the parent dir is marked as opaque (a variation of whiteout), or the
+  target (creating) file is whiteout-ed on the upper readonly branch,
+  then the result of the policy is ignored and the target file will be
+  created on the nearest upper writable branch than the readonly branch.
+- If there is a writable branch above the policy-selected branch and
+  the parent dir is marked as opaque or the target file is whiteouted
+  on the branch, then the result of the policy is ignored and the target
+  file will be created on the highest one among the upper writable
+  branches who has diropq or whiteout. In case of whiteout, aufs removes
+  it as usual.
+- link(2) and rename(2) systemcalls are exceptions in every policy.
+  They try selecting the branch where the source exists as possible
+  since copyup a large file will take long time. If it can't be,
+  ie. the branch where the source exists is readonly, then they will
+  follow the copyup policy.
+- There is an exception for rename(2) when the target exists.
+  If the rename target exists, aufs compares the index of the branches
+  where the source and the target exists and selects the higher
+  one. If the selected branch is readonly, then aufs follows the
+  copyup policy.

+
+Special handling for renaming a directory (DIRREN)
+----------------------------------------------------------------------
+First, let's assume we have a simple usecase.
+
+- /u = /rw + /ro
+- /rw/dirA exists
+- /ro/dirA and /ro/dirA/file exist too
+- there is no dirB on both branches
+- a user issues rename("dirA", "dirB")
+
+Now, what should aufs behave against this rename(2)?
+There are a few possible cases.
+
+A. returns EROFS.
+   since dirA exists on a readonly branch which cannot be renamed.
+B. returns EXDEV.
+   it is possible to copy-up dirA (only the dir itself), but the child
+   entries ("file" in this case) should not be. it must be a bad
+   approach to copy-up recursively.
+C. returns a success.
+   even the branch /ro is readonly, aufs tries renaming it. Obviously it
+   is a violation of aufs' policy.
+D. construct an extra information which indicates that /ro/dirA should
+   be handled as the name of dirB.
+   overlayfs has a similar feature called REDIRECT.
+
+Until now, aufs implements the case B only which returns EXDEV, and
+expects the userspace application behaves like mv(1) which tries
+issueing rename(2) recursively.
+
+A new aufs feature called DIRREN is introduced which implements the case
+D. There are several "extra information" added.
+
+1. detailed info per renamed directory
+   path: /rw/dirB/$AUFS_WH_DR_INFO_PFX.<lower branch-id>
+2. the inode-number list of directories on a branch
+   path: /rw/dirB/$AUFS_WH_DR_BRHINO
+
+The filename of "detailed info per directory" represents the lower
+branch, and its format is
+- a type of the branch id
+  one of these.
+  + uuid (not implemented yet)
+  + fsid
+  + dev
+- the inode-number of the branch root dir
+
+And it contains these info in a single regular file.
+- magic number
+- branch's inode-number of the logically renamed dir
+- the name of the before-renamed dir
+
+The "detailed info per directory" file is created in aufs rename(2), and
+loaded in any lookup.
+The info is considered in lookup for the matching case only. Here
+"matching" means that the root of branch (in the info filename) is same
+to the current looking-up branch. After looking-up the before-renamed
+name, the inode-number is compared. And the matched dentry is used.
+
+The "inode-number list of directories" is a regular file which contains
+simply the inode-numbers on the branch. The file is created or updated
+in removing the branch, and loaded in adding the branch. Its lifetime is
+equal to the branch.
+The list is refered in lookup, and when the current target inode is
+found in the list, the aufs tries loading the "detailed info per
+directory" and get the changed and valid name of the dir.
+
+Theoretically these "extra informaiton" may be able to be put into XATTR
+in the dir inode. But aufs doesn't choose this way because
+1. XATTR may not be supported by the branch (or its configuration)
+2. XATTR may have its size limit.
+3. XATTR may be less easy to convert than a regular file, when the
+   format of the info is changed in the future.
+At the same time, I agree that the regular file approach is much slower
+than XATTR approach. So, in the future, aufs may take the XATTR or other
+better approach.
+
+This DIRREN feature is enabled by aufs configuration, and is activated
+by a new mount option.
+
+For the more complicated case, there is a work with UDBA option, which
+is to dected the direct access to the branches (by-passing aufs) and to
+maintain the cashes in aufs. Since a single cached aufs dentry may
+contains two names, before- and after-rename, the name comparision in
+UDBA handler may not work correctly. In this case, the behaviour will be
+equivalen to udba=reval case.

+File-based Hierarchical Storage Management (FHSM)
+----------------------------------------------------------------------
+Hierarchical Storage Management (or HSM) is a well-known feature in the
+storage world. Aufs provides this feature as file-based with multiple
+writable branches, based upon the principle of "Colder, the Lower".
+Here the word "colder" means that the less used files, and "lower" means
+that the position in the order of the stacked branches vertically.
+These multiple writable branches are prioritized, ie. the topmost one
+should be the fastest drive and be used heavily.
+
+o Characters in aufs FHSM story
+- aufs itself and a new branch attribute.
+- a new ioctl interface to move-down and to establish a connection with
+  the daemon ("move-down" is a converse of "copy-up").
+- userspace tool and daemon.
+
+The userspace daemon establishes a connection with aufs and waits for
+the notification. The notified information is very similar to struct
+statfs containing the number of consumed blocks and inodes.
+When the consumed blocks/inodes of a branch exceeds the user-specified
+upper watermark, the daemon activates its move-down process until the
+consumed blocks/inodes reaches the user-specified lower watermark.
+
+The actual move-down is done by aufs based upon the request from
+user-space since we need to maintain the inode number and the internal
+pointer arrays in aufs.
+
+Currently aufs FHSM handles the regular files only. Additionally they
+must not be hard-linked nor pseudo-linked.
+
+
+o Cowork of aufs and the user-space daemon
+  During the userspace daemon established the connection, aufs sends a
+  small notification to it whenever aufs writes something into the
+  writable branch. But it may cost high since aufs issues statfs(2)
+  internally. So user can specify a new option to cache the
+  info. Actually the notification is controlled by these factors.
+  + the specified cache time.
+  + classified as "force" by aufs internally.
+  Until the specified time expires, aufs doesn't send the info
+  except the forced cases. When aufs decide forcing, the info is always
+  notified to userspace.
+  For example, the number of free inodes is generally large enough and
+  the shortage of it happens rarely. So aufs doesn't force the
+  notification when creating a new file, directory and others. This is
+  the typical case which aufs doesn't force.
+  When aufs writes the actual filedata and the files consumes any of new
+  blocks, the aufs forces notifying.
+
+
+o Interfaces in aufs
+- New branch attribute.
+  + fhsm
+    Specifies that the branch is managed by FHSM feature. In other word,
+    participant in the FHSM.
+    When nofhsm is set to the branch, it will not be the source/target
+    branch of the move-down operation. This attribute is set
+    independently from coo and moo attributes, and if you want full
+    FHSM, you should specify them as well.
+- New mount option.
+  + fhsm_sec
+    Specifies a second to suppress many less important info to be
+    notified.
+- New ioctl.
+  + AUFS_CTL_FHSM_FD
+    create a new file descriptor which userspace can read the notification
+    (a subset of struct statfs) from aufs.
+- Module parameter 'brs'
+  It has to be set to 1. Otherwise the new mount option 'fhsm' will not
+  be set.
+- mount helpers /sbin/mount.aufs and /sbin/umount.aufs
+  When there are two or more branches with fhsm attributes,
+  /sbin/mount.aufs invokes the user-space daemon and /sbin/umount.aufs
+  terminates it. As a result of remounting and branch-manipulation, the
+  number of branches with fhsm attribute can be one. In this case,
+  /sbin/mount.aufs will terminate the user-space daemon.
+
+
+Finally the operation is done as these steps in kernel-space.
+- make sure that,
+  + no one else is using the file.
+  + the file is not hard-linked.
+  + the file is not pseudo-linked.
+  + the file is a regular file.
+  + the parent dir is not opaqued.
+- find the target writable branch.
+- make sure the file is not whiteout-ed by the upper (than the target)
+  branch.
+- make the parent dir on the target branch.
+- mutex lock the inode on the branch.
+- unlink the whiteout on the target branch (if exists).
+- lookup and create the whiteout-ed temporary name on the target branch.
+- copy the file as the whiteout-ed temporary name on the target branch.
+- rename the whiteout-ed temporary name to the original name.
+- unlink the file on the source branch.
+- maintain the internal pointer array and the external inode number
+  table (XINO).
+- maintain the timestamps and other attributes of the parent dir and the
+  file.
+
+And of course, in every step, an error may happen. So the operation
+should restore the original file state after an error happens.

+mmap(2) -- File Memory Mapping
+----------------------------------------------------------------------
+In aufs, the file-mapped pages are handled by a branch fs directly, no
+interaction with aufs. It means aufs_mmap() calls the branch fs's
+->mmap().
+This approach is simple and good, but there is one problem.
+Under /proc, several entries show the mmapped files by its path (with
+device and inode number), and the printed path will be the path on the
+branch fs's instead of virtual aufs's.
+This is not a problem in most cases, but some utilities lsof(1) (and its
+user) may expect the path on aufs.
+
+To address this issue, aufs adds a new member called vm_prfile in struct
+vm_area_struct (and struct vm_region). The original vm_file points to
+the file on the branch fs in order to handle everything correctly as
+usual. The new vm_prfile points to a virtual file in aufs, and the
+show-functions in procfs refers to vm_prfile if it is set.
+Also we need to maintain several other places where touching vm_file
+such like
+- fork()/clone() copies vma and the reference count of vm_file is
+  incremented.
+- merging vma maintains the ref count too.
+
+This is not a good approach. It just fakes the printed path. But it
+leaves all behaviour around f_mapping unchanged. This is surely an
+advantage.
+Actually aufs had adopted another complicated approach which calls
+generic_file_mmap() and handles struct vm_operations_struct. In this
+approach, aufs met a hard problem and I could not solve it without
+switching the approach.
+
+There may be one more another approach which is
+- bind-mount the branch-root onto the aufs-root internally
+- grab the new vfsmount (ie. struct mount)
+- lazy-umount the branch-root internally
+- in open(2) the aufs-file, open the branch-file with the hidden
+  vfsmount (instead of the original branch's vfsmount)
+- ideally this "bind-mount and lazy-umount" should be done atomically,
+  but it may be possible from userspace by the mount helper.
+
+Adding the internal hidden vfsmount and using it in opening a file, the
+file path under /proc will be printed correctly. This approach looks
+smarter, but is not possible I am afraid.
+- aufs-root may be bind-mount later. when it happens, another hidden
+  vfsmount will be required.
+- it is hard to get the chance to bind-mount and lazy-umount
+  + in kernel-space, FS can have vfsmount in open(2) via
+    file->f_path, and aufs can know its vfsmount. But several locks are
+    already acquired, and if aufs tries to bind-mount and lazy-umount
+    here, then it may cause a deadlock.
+  + in user-space, bind-mount doesn't invoke the mount helper.
+- since /proc shows dev and ino, aufs has to give vma these info. it
+  means a new member vm_prinode will be necessary. this is essentially
+  equivalent to vm_prfile described above.
+
+I have to give up this "looks-smater" approach.

+
+Listing XATTR/EA and getting the value
+----------------------------------------------------------------------
+For the inode standard attributes (owner, group, timestamps, etc.), aufs
+shows the values from the topmost existing file. This behaviour is good
+for the non-dir entries since the bahaviour exactly matches the shown
+information. But for the directories, aufs considers all the same named
+entries on the lower branches. Which means, if one of the lower entry
+rejects readdir call, then aufs returns an error even if the topmost
+entry allows it. This behaviour is necessary to respect the branch fs's
+security, but can make users confused since the user-visible standard
+attributes don't match the behaviour.
+To address this issue, aufs has a mount option called dirperm1 which
+checks the permission for the topmost entry only, and ignores the lower
+entry's permission.
+
+A similar issue can happen around XATTR.
+getxattr(2) and listxattr(2) families behave as if dirperm1 option is
+always set. Otherwise these very unpleasant situation would happen.
+- listxattr(2) may return the duplicated entries.
+- users may not be able to remove or reset the XATTR forever,
+
+
+XATTR/EA support in the internal (copy,move)-(up,down)
+----------------------------------------------------------------------
+Generally the extended attributes of inode are categorized as these.
+- "security" for LSM and capability.
+- "system" for posix ACL, 'acl' mount option is required for the branch
+  fs generally.
+- "trusted" for userspace, CAP_SYS_ADMIN is required.
+- "user" for userspace, 'user_xattr' mount option is required for the
+  branch fs generally.
+
+Moreover there are some other categories. Aufs handles these rather
+unpopular categories as the ordinary ones, ie. there is no special
+condition nor exception.
+
+In copy-up, the support for XATTR on the dst branch may differ from the
+src branch. In this case, the copy-up operation will get an error and
+the original user operation which triggered the copy-up will fail. It
+can happen that even all copy-up will fail.
+When both of src and dst branches support XATTR and if an error occurs
+during copying XATTR, then the copy-up should fail obviously. That is a
+good reason and aufs should return an error to userspace. But when only
+the src branch support that XATTR, aufs should not return an error.
+For example, the src branch supports ACL but the dst branch doesn't
+because the dst branch may natively un-support it or temporary
+un-support it due to "noacl" mount option. Of course, the dst branch fs
+may NOT return an error even if the XATTR is not supported. It is
+totally up to the branch fs.
+
+Anyway when the aufs internal copy-up gets an error from the dst branch
+fs, then aufs tries removing the just copied entry and returns the error
+to the userspace. The worst case of this situation will be all copy-up
+will fail.
+
+For the copy-up operation, there two basic approaches.
+- copy the specified XATTR only (by category above), and return the
+  error unconditionally if it happens.
+- copy all XATTR, and ignore the error on the specified category only.
+
+In order to support XATTR and to implement the correct behaviour, aufs
+chooses the latter approach and introduces some new branch attributes,
+"icexsec", "icexsys", "icextr", "icexusr", and "icexoth".
+They correspond to the XATTR namespaces (see above). Additionally, to be
+convenient, "icex" is also provided which means all "icex*" attributes
+are set (here the word "icex" stands for "ignore copy-error on XATTR").
+
+The meaning of these attributes is to ignore the error from setting
+XATTR on that branch.
+Note that aufs tries copying all XATTR unconditionally, and ignores the
+error from the dst branch according to the specified attributes.
+
+Some XATTR may have its default value. The default value may come from
+the parent dir or the environment. If the default value is set at the
+file creating-time, it will be overwritten by copy-up.
+Some contradiction may happen I am afraid.
+Do we need another attribute to stop copying XATTR? I am unsure. For
+now, aufs implements the branch attributes to ignore the error.

+Export Aufs via NFS
+----------------------------------------------------------------------
+Here is an approach.
+- like xino/xib, add a new file 'xigen' which stores aufs inode
+  generation.
+- iget_locked(): initialize aufs inode generation for a new inode, and
+  store it in xigen file.
+- destroy_inode(): increment aufs inode generation and store it in xigen
+  file. it is necessary even if it is not unlinked, because any data of
+  inode may be changed by UDBA.
+- encode_fh(): for a root dir, simply return FILEID_ROOT. otherwise
+  build file handle by
+  + branch id (4 bytes)
+  + superblock generation (4 bytes)
+  + inode number (4 or 8 bytes)
+  + parent dir inode number (4 or 8 bytes)
+  + inode generation (4 bytes))
+  + return value of exportfs_encode_fh() for the parent on a branch (4
+    bytes)
+  + file handle for a branch (by exportfs_encode_fh())

+Show Whiteout Mode (shwh)
+----------------------------------------------------------------------
+Generally aufs hides the name of whiteouts. But in some cases, to show
+them is very useful for users. For instance, creating a new middle layer
+(branch) by merging existing layers.
+
+(borrowing aufs1 HOW-TO from a user, Michael Towers)
+When you have three branches,
+- Bottom: 'system', squashfs (underlying base system), read-only
+- Middle: 'mods', squashfs, read-only
+- Top: 'overlay', ram (tmpfs), read-write
+
+The top layer is loaded at boot time and saved at shutdown, to preserve
+the changes made to the system during the session.
+When larger changes have been made, or smaller changes have accumulated,
+the size of the saved top layer data grows. At this point, it would be
+nice to be able to merge the two overlay branches ('mods' and 'overlay')
+and rewrite the 'mods' squashfs, clearing the top layer and thus
+restoring save and load speed.
+
+This merging is simplified by the use of another aufs mount, of just the
+two overlay branches using the 'shwh' option.
+# mount -t aufs -o ro,shwh,br:/livesys/overlay=ro+wh:/livesys/mods=rr+wh \
+	aufs /livesys/merge_union
+
+A merged view of these two branches is then available at
+/livesys/merge_union, and the new feature is that the whiteouts are
+visible!
+Note that in 'shwh' mode the aufs mount must be 'ro', which will disable
+writing to all branches. Also the default mode for all branches is 'ro'.
+It is now possible to save the combined contents of the two overlay
+branches to a new squashfs, e.g.:
+# mksquashfs /livesys/merge_union /path/to/newmods.squash
+
+This new squashfs archive can be stored on the boot device and the
+initramfs will use it to replace the old one at the next boot.

+Dynamically customizable FS operations
+----------------------------------------------------------------------
+Generally FS operations (struct inode_operations, struct
+address_space_operations, struct file_operations, etc.) are defined as
+"static const", but it never means that FS have only one set of
+operation. Some FS have multiple sets of them. For instance, ext2 has
+three sets, one for XIP, for NOBH, and for normal.
+Since aufs overrides and redirects these operations, sometimes aufs has
+to change its behaviour according to the branch FS type. More importantly
+VFS acts differently if a function (member in the struct) is set or
+not. It means aufs should have several sets of operations and select one
+among them according to the branch FS definition.
+
+In order to solve this problem and not to affect the behaviour of VFS,
+aufs defines these operations dynamically. For instance, aufs defines
+dummy direct_IO function for struct address_space_operations, but it may
+not be set to the address_space_operations actually. When the branch FS
+doesn't have it, aufs doesn't set it to its address_space_operations
+while the function definition itself is still alive. So the behaviour
+itself will not change, and it will return an error when direct_IO is
+not set.
+
+The lifetime of these dynamically generated operation object is
+maintained by aufs branch object. When the branch is removed from aufs,
+the reference counter of the object is decremented. When it reaches
+zero, the dynamically generated operation object will be freed.
+
+This approach is designed to support AIO (io_submit), Direct I/O and
+XIP (DAX) mainly.
+Currently this approach is applied to address_space_operations for
+regular files only.

+==============================
+Building Linux with Clang/LLVM
+==============================
+
+This document covers how to build the Linux kernel with Clang and LLVM
+utilities.
+
+About
+-----
+
+The Linux kernel has always traditionally been compiled with GNU toolchains
+such as GCC and binutils. Ongoing work has allowed for `Clang
+<https://clang.llvm.org/>`_ and `LLVM <https://llvm.org/>`_ utilities to be
+used as viable substitutes. Distributions such as `Android
+<https://www.android.com/>`_, `ChromeOS
+<https://www.chromium.org/chromium-os>`_, and `OpenMandriva
+<https://www.openmandriva.org/>`_ use Clang built kernels.  `LLVM is a
+collection of toolchain components implemented in terms of C++ objects
+<https://www.aosabook.org/en/llvm.html>`_. Clang is a front-end to LLVM that
+supports C and the GNU C extensions required by the kernel, and is pronounced
+"klang," not "see-lang."
+
+Clang
+-----
+
+The compiler used can be swapped out via `CC=` command line argument to `make`.
+`CC=` should be set when selecting a config and during a build.
+
+	make CC=clang defconfig
+
+	make CC=clang
+
+Cross Compiling
+---------------
+
+A single Clang compiler binary will typically contain all supported backends,
+which can help simplify cross compiling.
+
+	ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make CC=clang
+
+`CROSS_COMPILE` is not used to prefix the Clang compiler binary, instead
+`CROSS_COMPILE` is used to set a command line flag: `--target <triple>`. For
+example:
+
+	clang --target aarch64-linux-gnu foo.c
+
+LLVM Utilities
+--------------
+
+LLVM has substitutes for GNU binutils utilities. Kbuild supports `LLVM=1`
+to enable them.
+
+	make LLVM=1
+
+They can be enabled individually. The full list of the parameters:
+
+	make CC=clang LD=ld.lld AR=llvm-ar NM=llvm-nm STRIP=llvm-strip \\
+	  OBJCOPY=llvm-objcopy OBJDUMP=llvm-objdump OBJSIZE=llvm-size \\
+	  READELF=llvm-readelf HOSTCC=clang HOSTCXX=clang++ HOSTAR=llvm-ar \\

+Read-only sub-device userspace API
+----------------------------------
+
+Bridge drivers that control their connected subdevices through direct calls to
+the kernel API realized by :c:type:`v4l2_subdev_ops` structure do not usually
+want userspace to be able to change the same parameters through the subdevice
+device node and thus do not usually register any.
+
+It is sometimes useful to report to userspace the current subdevice
+configuration through a read-only API, that does not permit applications to
+change to the device parameters but allows interfacing to the subdevice device
+node to inspect them.
+
+For instance, to implement cameras based on computational photography, userspace
+needs to know the detailed camera sensor configuration (in terms of skipping,
+binning, cropping and scaling) for each supported output resolution. To support
+such use cases, bridge drivers may expose the subdevice operations to userspace
+through a read-only API.
+
+To create a read-only device node for all the subdevices registered with the
+``V4L2_SUBDEV_FL_HAS_DEVNODE`` set, the :c:type:`v4l2_device` driver should call
+:c:func:`v4l2_device_register_ro_subdev_nodes`.
+
+Access to the following ioctls for userspace applications is restricted on
+sub-device device nodes registered with
+:c:func:`v4l2_device_register_ro_subdev_nodes`.
+
+``VIDIOC_SUBDEV_S_FMT``,
+``VIDIOC_SUBDEV_S_CROP``,
+``VIDIOC_SUBDEV_S_SELECTION``:
+
+	These ioctls are only allowed on a read-only subdevice device node
+	for the :ref:`V4L2_SUBDEV_FORMAT_TRY <v4l2-subdev-format-whence>`
+	formats and selection rectangles.
+
+``VIDIOC_SUBDEV_S_FRAME_INTERVAL``,
+``VIDIOC_SUBDEV_S_DV_TIMINGS``,
+``VIDIOC_SUBDEV_S_STD``:
+
+	These ioctls are not allowed on a read-only subdevice node.
+
+In case the ioctl is not allowed, or the format to modify is set to
+``V4L2_SUBDEV_FORMAT_ACTIVE``, the core returns a negative error code and
+the errno variable is set to ``-EPERM``.

+    as a position relative to the device's intended usage orientation. For
+    example, a camera installed on the user-facing side of a phone, a tablet or

+    orientation, while a camera installed on the opposite side of the front one
+    is said to be have ``V4L2_CAMERA_ORIENTATION_BACK`` orientation. Camera
+    sensors not directly attached to the device, or attached in a way that

+    Example one - Webcam
+
+    Assuming you can bring your laptop with you while swimming with sharks,
+    the camera module of the laptop is installed on the user facing part of a
+    laptop screen casing, and is typically used for video calls. The captured
+    images are meant to be displayed in landscape mode (width > height) on the
+    laptop screen.
+
+    The camera is typically mounted upside-down to compensate the lens optical
+    inversion effect. In this case the value of the
+    V4L2_CID_CAMERA_SENSOR_ROTATION control is 0, no rotation is required to
+    display images correctly to the user.
+
+    If the camera sensor is not mounted upside-down it is required to compensate
+    the lens optical inversion effect and the value of the
+    V4L2_CID_CAMERA_SENSOR_ROTATION control is 180 degrees, as images will

+    Example two - Phone camera
+
+    It is more handy to go and swim with sharks with only your mobile phone
+    with you and take pictures with the camera that is installed on the back
+    side of the device, facing away from the user. The captured images are meant
+    to be displayed in portrait mode (height > width) to match the device screen
+    orientation and the device usage orientation used when taking the picture.
+
+    The camera sensor is typically mounted with its pixel array longer side
+    aligned to the device longer side, upside-down mounted to compensate for
+    the lens optical inversion effect.
+
+    The images once captured to memory will be rotated and the value of the
+    V4L2_CID_CAMERA_SENSOR_ROTATION will report a 90 degree rotation. ::

+own custom format for this ancillary data. Some vendors follow a generic
+CSI-2/SMIA embedded data format as described in the `CSI-2 specification.
+<https://mipi.org/specifications/csi-2>`_
+
+The size of the embedded buffer is defined as a single line with a pixel width
+width specified in bytes. This is obtained by a call to the
+:c:type:`VIDIOC_SUBDEV_G_FMT` ioctl on the sensor subdevice where the ``pad``
+field in :c:type:`v4l2_subdev_format` is set to 1.  Note that this size is fixed
+and cannot be modified with a call to :c:type:`VIDIOC_SUBDEV_S_FMT`.

+V4L2_PIX_FMT_NV21_COL128
+Formats with ½ horizontal and vertical chroma resolution. This format
+has two planes - one for luminance and one for chrominance. Chroma
+samples are interleaved. The difference to ``V4L2_PIX_FMT_NV12`` is the
+memory layout. The image is split into columns of 128 bytes wide rather than
+being in raster order.
+
+V4L2_PIX_FMT_NV12_10_COL128
+Follows the same pattern as ``V4L2_PIX_FMT_NV21_COL128`` with 128 byte, but is
+a 10bit format with 3 10-bit samples being packed into 4 bytes. Each 128 byte
+wide column therefore contains 96 samples.
+
+
+Description
+===========
+
+This is the two-plane versions of the YUV 4:2:0 format where data is
+grouped into 128 byte wide columns. The three components are separated into
+two sub-images or planes. The Y plane has one byte per pixel and pixels
+are grouped into 128 byte wide columns. The CbCr plane has the same width,
+in bytes, as the Y plane (and the image), but is half as tall in pixels.
+The chroma plane is also in 128 byte columns, reflecting 64 Cb and 64 Cr
+samples.
+
+The chroma samples for a column follow the luma samples. If there is any
+paddding, then that will be reflected via the selection API.
+The luma height must be a multiple of 2 lines.
+
+The normal bytesperline is effectively fixed at 128. However the format
+requires knowledge of the stride between columns, therefore the bytesperline
+value has been repurposed to denote the number of 128 byte long lines between
+the start of each column.

+3 10-bit values are packed into 4 bytes as bits 9:0, 19:10, and 29:20, with
+bits 30 & 31 unused. For the luma plane, bits 9:0 are Y0, 19:10 are Y1, and

+These four pixel formats are raw sRGB / Bayer formats with 14 bits per
+colour. Each sample is stored in a 16-bit word, with two unused high
+bits filled with zeros. Each n-pixel row contains n/2 green samples
+and n/2 blue or red samples, with alternating red and blue rows. Bytes
+are stored in memory in little endian order. They are conventionally
+described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an
+example of a small V4L2_PIX_FMT_SBGGR14 image:

+BCM2835 ISP Driver
+==================
+
+Introduction
+------------
+
+The BCM2835 Image Sensor Pipeline (ISP) is a fixed function hardware pipeline
+for performing image processing operations.  Images are fed to the input
+of the ISP through memory frame buffers.  These images may be in various YUV,
+RGB, or Bayer formats.  A typical use case would have Bayer images obtained from
+an image sensor by the BCM2835 Unicam peripheral, written to a memory
+frame buffer, and finally fed into the input of the ISP.  Two concurrent output
+images may be generated in YUV or RGB format at different resolutions.
+Statistics output is also generated for Bayer input images.
+
+The bcm2835-isp driver exposes the following media pads as V4L2 device nodes:

+Configuration Flags and Socket Options
+======================================
+
+These are the various configuration flags that can be used to control
+and monitor the behavior of AF_XDP sockets.
+
+XDP_COPY and XDP_ZERO_COPY bind flags
+-------------------------------------
+
+When you bind to a socket, the kernel will first try to use zero-copy
+copy. If zero-copy is not supported, it will fall back on using copy
+mode, i.e. copying all packets out to user space. But if you would
+like to force a certain mode, you can use the following flags. If you
+pass the XDP_COPY flag to the bind call, the kernel will force the
+socket into copy mode. If it cannot use copy mode, the bind call will
+fail with an error. Conversely, the XDP_ZERO_COPY flag will force the
+socket into zero-copy mode or fail.
+
+XDP_SHARED_UMEM bind flag
+-------------------------
+
+This flag enables you to bind multiple sockets to the same UMEM, but
+only if they share the same queue id. In this mode, each socket has
+their own RX and TX rings, but the UMEM (tied to the fist socket
+created) only has a single FILL ring and a single COMPLETION
+ring. To use this mode, create the first socket and bind it in the normal
+way. Create a second socket and create an RX and a TX ring, or at
+least one of them, but no FILL or COMPLETION rings as the ones from
+the first socket will be used. In the bind call, set he
+XDP_SHARED_UMEM option and provide the initial socket's fd in the
+sxdp_shared_umem_fd field. You can attach an arbitrary number of extra
+sockets this way.
+
+What socket will then a packet arrive on? This is decided by the XDP
+program. Put all the sockets in the XSK_MAP and just indicate which
+index in the array you would like to send each packet to. A simple
+round-robin example of distributing packets is shown below:
+
+.. code-block:: c
+
+   #include <linux/bpf.h>
+   #include "bpf_helpers.h"
+
+   #define MAX_SOCKS 16
+
+   struct {
+        __uint(type, BPF_MAP_TYPE_XSKMAP);
+        __uint(max_entries, MAX_SOCKS);
+        __uint(key_size, sizeof(int));
+        __uint(value_size, sizeof(int));
+   } xsks_map SEC(".maps");
+
+   static unsigned int rr;
+
+   SEC("xdp_sock") int xdp_sock_prog(struct xdp_md *ctx)
+   {
+	rr = (rr + 1) & (MAX_SOCKS - 1);
+
+	return bpf_redirect_map(&xsks_map, rr, 0);
+   }
+
+Note, that since there is only a single set of FILL and COMPLETION
+rings, and they are single producer, single consumer rings, you need
+to make sure that multiple processes or threads do not use these rings
+concurrently. There are no synchronization primitives in the
+libbpf code that protects multiple users at this point in time.
+
+XDP_USE_NEED_WAKEUP bind flag
+-----------------------------
+
+This option adds support for a new flag called need_wakeup that is
+present in the FILL ring and the TX ring, the rings for which user
+space is a producer. When this option is set in the bind call, the
+need_wakeup flag will be set if the kernel needs to be explicitly
+woken up by a syscall to continue processing packets. If the flag is
+zero, no syscall is needed.
+
+If the flag is set on the FILL ring, the application needs to call
+poll() to be able to continue to receive packets on the RX ring. This
+can happen, for example, when the kernel has detected that there are no
+more buffers on the FILL ring and no buffers left on the RX HW ring of
+the NIC. In this case, interrupts are turned off as the NIC cannot
+receive any packets (as there are no buffers to put them in), and the
+need_wakeup flag is set so that user space can put buffers on the
+FILL ring and then call poll() so that the kernel driver can put these
+buffers on the HW ring and start to receive packets.
+
+If the flag is set for the TX ring, it means that the application
+needs to explicitly notify the kernel to send any packets put on the
+TX ring. This can be accomplished either by a poll() call, as in the
+RX path, or by calling sendto().
+
+An example of how to use this flag can be found in
+samples/bpf/xdpsock_user.c. An example with the use of libbpf helpers
+would look like this for the TX path:
+
+.. code-block:: c
+
+   if (xsk_ring_prod__needs_wakeup(&my_tx_ring))
+      sendto(xsk_socket__fd(xsk_handle), NULL, 0, MSG_DONTWAIT, NULL, 0);
+
+I.e., only use the syscall if the flag is set.
+
+We recommend that you always enable this mode as it usually leads to
+better performance especially if you run the application and the
+driver on the same core, but also if you use different cores for the
+application and the kernel driver, as it reduces the number of
+syscalls needed for the TX path.
+
+XDP_{RX|TX|UMEM_FILL|UMEM_COMPLETION}_RING setsockopts
+------------------------------------------------------
+
+These setsockopts sets the number of descriptors that the RX, TX,
+FILL, and COMPLETION rings respectively should have. It is mandatory
+to set the size of at least one of the RX and TX rings. If you set
+both, you will be able to both receive and send traffic from your
+application, but if you only want to do one of them, you can save
+resources by only setting up one of them. Both the FILL ring and the
+COMPLETION ring are mandatory if you have a UMEM tied to your socket,
+which is the normal case. But if the XDP_SHARED_UMEM flag is used, any
+socket after the first one does not have a UMEM and should in that
+case not have any FILL or COMPLETION rings created.
+
+XDP_UMEM_REG setsockopt
+-----------------------
+
+This setsockopt registers a UMEM to a socket. This is the area that
+contain all the buffers that packet can recide in. The call takes a
+pointer to the beginning of this area and the size of it. Moreover, it
+also has parameter called chunk_size that is the size that the UMEM is
+divided into. It can only be 2K or 4K at the moment. If you have an
+UMEM area that is 128K and a chunk size of 2K, this means that you
+will be able to hold a maximum of 128K / 2K = 64 packets in your UMEM
+area and that your largest packet size can be 2K.
+
+There is also an option to set the headroom of each single buffer in
+the UMEM. If you set this to N bytes, it means that the packet will
+start N bytes into the buffer leaving the first N bytes for the
+application to use. The final option is the flags field, but it will
+be dealt with in separate sections for each UMEM flag.
+
+SO_BINDTODEVICE setsockopt
+--------------------------
+
+This is a generic SOL_SOCKET option that can be used to tie AF_XDP
+socket to a particular network interface.  It is useful when a socket
+is created by a privileged process and passed to a non-privileged one.
+Once the option is set, kernel will refuse attempts to bind that socket
+to a different interface.  Updating the value requires CAP_NET_RAW.
+
+XDP_STATISTICS getsockopt
+-------------------------
+
+Gets drop statistics of a socket that can be useful for debug
+purposes. The supported statistics are shown below:
+
+.. code-block:: c
+
+   struct xdp_statistics {
+	  __u64 rx_dropped; /* Dropped for reasons other than invalid desc */
+	  __u64 rx_invalid_descs; /* Dropped due to invalid descriptor */
+	  __u64 tx_invalid_descs; /* Dropped due to invalid descriptor */
+   };
+
+XDP_OPTIONS getsockopt
+----------------------
+
+Gets options from an XDP socket. The only one supported so far is
+XDP_OPTIONS_ZEROCOPY which tells you if zero-copy is on or not.

+Realtek PC Beep Hidden Register
+===============================
+
+This file documents the "PC Beep Hidden Register", which is present in certain
+Realtek HDA codecs and controls a muxer and pair of passthrough mixers that can
+route audio between pins but aren't themselves exposed as HDA widgets. As far
+as I can tell, these hidden routes are designed to allow flexible PC Beep output
+for codecs that don't have mixer widgets in their output paths. Why it's easier
+to hide a mixer behind an undocumented vendor register than to just expose it
+as a widget, I have no idea.
+
+Register Description
+====================
+
+The register is accessed via processing coefficient 0x36 on NID 20h. Bits not
+identified below have no discernible effect on my machine, a Dell XPS 13 9350::

+1Ah input select (B): 2 bits
+  When zero, expose the PC Beep line (from the internal beep generator, when
+  enabled with the Set Beep Generation verb on NID 01h, or else from the
+  external PCBEEP pin) on the 1Ah pin node. When nonzero, expose the headphone
+  jack (or possibly Line In on some machines) input instead. If PC Beep is
+  selected, the 1Ah boost control has no effect.
+
+Amplify 1Ah loopback, left (L): 1 bit
+  Amplify the left channel of 1Ah before mixing it into outputs as specified
+  by h and S bits. Does not affect the level of 1Ah exposed to other widgets.
+
+Amplify 1Ah loopback, right (R): 1 bit
+  Amplify the right channel of 1Ah before mixing it into outputs as specified
+  by h and S bits. Does not affect the level of 1Ah exposed to other widgets.
+
+Loopback 1Ah to 21h [active low] (h): 1 bit
+  When zero, mix 1Ah (possibly with amplification, depending on L and R bits)
+  into 21h (headphone jack on my machine). Mixed signal respects the mute
+  setting on 21h.
+
+Loopback 1Ah to 14h (S): 1 bit
+  When one, mix 1Ah (possibly with amplification, depending on L and R bits)
+  into 14h (internal speaker on my machine). Mixed signal **ignores** the mute
+  setting on 14h and is present whenever 14h is configured as an output.

+
+Background
+==========
+
+All Realtek HDA codecs have a vendor-defined widget with node ID 20h which
+provides access to a bank of registers that control various codec functions.
+Registers are read and written via the standard HDA processing coefficient
+verbs (Set/Get Coefficient Index, Set/Get Processing Coefficient). The node is
+named "Realtek Vendor Registers" in public datasheets' verb listings and,
+apart from that, is entirely undocumented.
+
+This particular register, exposed at coefficient 0x36 and named in commits from
+Realtek, is of note: unlike most registers, which seem to control detailed
+amplifier parameters not in scope of the HDA specification, it controls audio
+routing which could just as easily have been defined using standard HDA mixer
+and selector widgets.
+
+Specifically, it selects between two sources for the input pin widget with Node
+ID (NID) 1Ah: the widget's signal can come either from an audio jack (on my
+laptop, a Dell XPS 13 9350, it's the headphone jack, but comments in Realtek
+commits indicate that it might be a Line In on some machines) or from the PC
+Beep line (which is itself multiplexed between the codec's internal beep
+generator and external PCBEEP pin, depending on if the beep generator is
+enabled via verbs on NID 01h). Additionally, it can mix (with optional
+amplification) that signal onto the 21h and/or 14h output pins.
+
+The register's reset value is 0x3717, corresponding to PC Beep on 1Ah that is
+then amplified and mixed into both the headphones and the speakers. Not only
+does this violate the HDA specification, which says that "[a vendor defined
+beep input pin] connection may be maintained *only* while the Link reset
+(**RST#**) is asserted", it means that we cannot ignore the register if we care
+about the input that 1Ah would otherwise expose or if the PCBEEP trace is
+poorly shielded and picks up chassis noise (both of which are the case on my
+machine).
+
+Unfortunately, there are lots of ways to get this register configuration wrong.
+Linux, it seems, has gone through most of them. For one, the register resets
+after S3 suspend: judging by existing code, this isn't the case for all vendor
+registers, and it's led to some fixes that improve behavior on cold boot but
+don't last after suspend. Other fixes have successfully switched the 1Ah input
+away from PC Beep but have failed to disable both loopback paths. On my
+machine, this means that the headphone input is amplified and looped back to
+the headphone output, which uses the exact same pins! As you might expect, this
+causes terrible headphone noise, the character of which is controlled by the
+1Ah boost control. (If you've seen instructions online to fix XPS 13 headphone
+noise by changing "Headphone Mic Boost" in ALSA, now you know why.)
+
+The information here has been obtained through black-box reverse engineering of
+the ALC256 codec's behavior and is not guaranteed to be correct. It likely
+also applies for the ALC255, ALC257, ALC235, and ALC236, since those codecs
+seem to be close relatives of the ALC256. (They all share one initialization
+function.) Additionally, other codecs like the ALC225 and ALC285 also have this
+register, judging by existing fixups in ``patch_realtek.c``, but specific
+data (e.g. node IDs, bit positions, pin mappings) for those codecs may differ
+from what I've described here.

+Logical read/write:

+Access logical memory, i.e. translate the given guest address to an absolute
+address given the state of the VCPU and use the absolute address as target of
+the access. "ar" designates the access register number to be used; the valid

+  * ``KVM_S390_MEMOP_F_SKEY_PROTECTION``
+
+The KVM_S390_MEMOP_F_CHECK_ONLY flag can be set to check whether the

+In this case, "buf" is unused and can be NULL.

+In case an access exception occurred during the access (or would occur

+Absolute read/write:
+
+Access absolute memory. This operation is intended to be used with the
+KVM_S390_MEMOP_F_SKEY_PROTECTION flag, to allow accessing memory and performing
+the checks required for storage key protection as one operation (as opposed to
+user space getting the storage keys, performing the checks, and accessing
+memory thereafter, which could lead to a delay between check and access).
+Absolute accesses are permitted for the VM ioctl if KVM_CAP_S390_MEM_OP_EXTENSION
+is > 0.
+Currently absolute accesses are not permitted for VCPU ioctls.
+Absolute accesses are permitted for non-protected guests only.

+s390 (IBM Z) Boot/IPL of Protected VMs
+======================================
+
+Summary
+-------
+The memory of Protected Virtual Machines (PVMs) is not accessible to
+I/O or the hypervisor. In those cases where the hypervisor needs to
+access the memory of a PVM, that memory must be made accessible.
+Memory made accessible to the hypervisor will be encrypted. See
+:doc:`s390-pv` for details."
+
+On IPL (boot) a small plaintext bootloader is started, which provides
+information about the encrypted components and necessary metadata to
+KVM to decrypt the protected virtual machine.
+
+Based on this data, KVM will make the protected virtual machine known
+to the Ultravisor (UV) and instruct it to secure the memory of the
+PVM, decrypt the components and verify the data and address list
+hashes, to ensure integrity. Afterwards KVM can run the PVM via the
+SIE instruction which the UV will intercept and execute on KVM's
+behalf.
+
+As the guest image is just like an opaque kernel image that does the
+switch into PV mode itself, the user can load encrypted guest
+executables and data via every available method (network, dasd, scsi,
+direct kernel, ...) without the need to change the boot process.
+
+
+Diag308
+-------
+This diagnose instruction is the basic mechanism to handle IPL and
+related operations for virtual machines. The VM can set and retrieve
+IPL information blocks, that specify the IPL method/devices and
+request VM memory and subsystem resets, as well as IPLs.
+
+For PVMs this concept has been extended with new subcodes:
+
+Subcode 8: Set an IPL Information Block of type 5 (information block
+for PVMs)
+Subcode 9: Store the saved block in guest memory
+Subcode 10: Move into Protected Virtualization mode
+
+The new PV load-device-specific-parameters field specifies all data
+that is necessary to move into PV mode.
+
+* PV Header origin
+* PV Header length
+* List of Components composed of
+   * AES-XTS Tweak prefix
+   * Origin
+   * Size
+
+The PV header contains the keys and hashes, which the UV will use to
+decrypt and verify the PV, as well as control flags and a start PSW.
+
+The components are for instance an encrypted kernel, kernel parameters
+and initrd. The components are decrypted by the UV.
+
+After the initial import of the encrypted data, all defined pages will
+contain the guest content. All non-specified pages will start out as
+zero pages on first access.
+
+
+When running in protected virtualization mode, some subcodes will result in
+exceptions or return error codes.
+
+Subcodes 4 and 7, which specify operations that do not clear the guest
+memory, will result in specification exceptions. This is because the
+UV will clear all memory when a secure VM is removed, and therefore
+non-clearing IPL subcodes are not allowed.
+
+Subcodes 8, 9, 10 will result in specification exceptions.
+Re-IPL into a protected mode is only possible via a detour into non
+protected mode.
+
+Keys
+----
+Every CEC will have a unique public key to enable tooling to build
+encrypted images.
+See  `s390-tools <https://github.com/ibm-s390-tools/s390-tools/>`_
+for the tooling.

+=========================================
+s390 (IBM Z) Ultravisor and Protected VMs
+=========================================
+
+Summary
+-------
+Protected virtual machines (PVM) are KVM VMs that do not allow KVM to
+access VM state like guest memory or guest registers. Instead, the
+PVMs are mostly managed by a new entity called Ultravisor (UV). The UV
+provides an API that can be used by PVMs and KVM to request management
+actions.
+
+Each guest starts in non-protected mode and then may make a request to
+transition into protected mode. On transition, KVM registers the guest
+and its VCPUs with the Ultravisor and prepares everything for running
+it.
+
+The Ultravisor will secure and decrypt the guest's boot memory
+(i.e. kernel/initrd). It will safeguard state changes like VCPU
+starts/stops and injected interrupts while the guest is running.
+
+As access to the guest's state, such as the SIE state description, is
+normally needed to be able to run a VM, some changes have been made in
+the behavior of the SIE instruction. A new format 4 state description
+has been introduced, where some fields have different meanings for a
+PVM. SIE exits are minimized as much as possible to improve speed and
+reduce exposed guest state.
+
+
+Interrupt injection
+-------------------
+Interrupt injection is safeguarded by the Ultravisor. As KVM doesn't
+have access to the VCPUs' lowcores, injection is handled via the
+format 4 state description.
+
+Machine check, external, IO and restart interruptions each can be
+injected on SIE entry via a bit in the interrupt injection control
+field (offset 0x54). If the guest cpu is not enabled for the interrupt
+at the time of injection, a validity interception is recognized. The
+format 4 state description contains fields in the interception data
+block where data associated with the interrupt can be transported.
+
+Program and Service Call exceptions have another layer of
+safeguarding; they can only be injected for instructions that have
+been intercepted into KVM. The exceptions need to be a valid outcome
+of an instruction emulation by KVM, e.g. we can never inject a
+addressing exception as they are reported by SIE since KVM has no
+access to the guest memory.
+
+
+Mask notification interceptions
+-------------------------------
+KVM cannot intercept lctl(g) and lpsw(e) anymore in order to be
+notified when a PVM enables a certain class of interrupt.  As a
+replacement, two new interception codes have been introduced: One
+indicating that the contents of CRs 0, 6, or 14 have been changed,
+indicating different interruption subclasses; and one indicating that
+PSW bit 13 has been changed, indicating that a machine check
+intervention was requested and those are now enabled.
+
+Instruction emulation
+---------------------
+With the format 4 state description for PVMs, the SIE instruction already
+interprets more instructions than it does with format 2. It is not able
+to interpret every instruction, but needs to hand some tasks to KVM;
+therefore, the SIE and the ultravisor safeguard emulation inputs and outputs.
+
+The control structures associated with SIE provide the Secure
+Instruction Data Area (SIDA), the Interception Parameters (IP) and the
+Secure Interception General Register Save Area.  Guest GRs and most of
+the instruction data, such as I/O data structures, are filtered.
+Instruction data is copied to and from the SIDA when needed.  Guest
+GRs are put into / retrieved from the Secure Interception General
+Register Save Area.
+
+Only GR values needed to emulate an instruction will be copied into this
+save area and the real register numbers will be hidden.
+
+The Interception Parameters state description field still contains the
+the bytes of the instruction text, but with pre-set register values
+instead of the actual ones. I.e. each instruction always uses the same
+instruction text, in order not to leak guest instruction text.
+This also implies that the register content that a guest had in r<n>
+may be in r<m> from the hypervisor's point of view.
+
+The Secure Instruction Data Area contains instruction storage
+data. Instruction data, i.e. data being referenced by an instruction
+like the SCCB for sclp, is moved via the SIDA. When an instruction is
+intercepted, the SIE will only allow data and program interrupts for
+this instruction to be moved to the guest via the two data areas
+discussed before. Other data is either ignored or results in validity
+interceptions.
+
+
+Instruction emulation interceptions
+-----------------------------------
+There are two types of SIE secure instruction intercepts: the normal
+and the notification type. Normal secure instruction intercepts will
+make the guest pending for instruction completion of the intercepted
+instruction type, i.e. on SIE entry it is attempted to complete
+emulation of the instruction with the data provided by KVM. That might
+be a program exception or instruction completion.
+
+The notification type intercepts inform KVM about guest environment
+changes due to guest instruction interpretation. Such an interception
+is recognized, for example, for the store prefix instruction to provide
+the new lowcore location. On SIE reentry, any KVM data in the data areas
+is ignored and execution continues as if the guest instruction had
+completed. For that reason KVM is not allowed to inject a program
+interrupt.

+Introduction
+============
+
+This directory contains Device Tree overlays. Device Tree makes it possible
+to support many hardware configurations with a single kernel and without the
+need to explicitly load or blacklist kernel modules. Note that this isn't a
+"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices
+are still configured by the board support code, but the intention is to
+eventually reach that goal.
+
+On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By
+default, the Raspberry Pi kernel boots with device tree enabled. You can
+completely disable DT usage (for now) by adding:
+
+    device_tree=
+
+to your config.txt, which should cause your Pi to revert to the old way of
+doing things after a reboot.
+
+In /boot you will find a .dtb for each base platform. This describes the
+hardware that is part of the Raspberry Pi board. The loader (start.elf and its
+siblings) selects the .dtb file appropriate for the platform by name, and reads
+it into memory. At this point, all of the optional interfaces (i2c, i2s, spi)
+are disabled, but they can be enabled using Device Tree parameters:
+
+    dtparam=i2c=on,i2s=on,spi=on
+
+However, this shouldn't be necessary in many use cases because loading an
+overlay that requires one of those interfaces will cause it to be enabled
+automatically, and it is advisable to only enable interfaces if they are
+needed.
+
+Configuring additional, optional hardware is done using Device Tree overlays
+(see below).
+
+GPIO numbering uses the hardware pin numbering scheme (aka BCM scheme) and
+not the physical pin numbers.
+
+raspi-config
+============
+
+The Advanced Options section of the raspi-config utility can enable and disable
+Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it
+is possible to both enable an interface and blacklist the driver, if for some
+reason you should want to defer the loading.
+
+Modules
+=======
+
+As well as describing the hardware, Device Tree also gives enough information
+to allow suitable driver modules to be located and loaded, with the corollary
+that unneeded modules are not loaded. As a result it should be possible to
+remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can
+have its contents deleted (or commented out).
+
+Using Overlays
+==============
+
+Overlays are loaded using the "dtoverlay" config.txt setting. As an example,
+consider I2C Real Time Clock drivers. In the pre-DT world these would be loaded
+by writing a magic string comprising a device identifier and an I2C address to
+a special file in /sys/class/i2c-adapter, having first loaded the driver for
+the I2C interface and the RTC device - something like this:
+
+    modprobe i2c-bcm2835
+    modprobe rtc-ds1307
+    echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
+
+With DT enabled, this becomes a line in config.txt:
+
+    dtoverlay=i2c-rtc,ds1307
+
+This causes the file /boot/overlays/i2c-rtc.dtbo to be loaded and a "node"
+describing the DS1307 I2C device to be added to the Device Tree for the Pi. By
+default it usees address 0x68, but this can be modified with an additional DT
+parameter:
+
+    dtoverlay=i2c-rtc,ds1307,addr=0x68
+
+Parameters usually have default values, although certain parameters are
+mandatory. See the list of overlays below for a description of the parameters
+and their defaults.
+
+Making new Overlays based on existing Overlays
+==============================================
+
+Recent overlays have been designed in a more general way, so that they can be
+adapted to hardware by changing their parameters. When you have additional
+hardware with more than one device of a kind, you end up using the same overlay
+multiple times with other parameters, e.g.
+
+    # 2 CAN FD interfaces on spi but with different pins
+    dtoverlay=mcp251xfd,spi0-0,interrupt=25
+    dtoverlay=mcp251xfd,spi0-1,interrupt=24
+
+    # a realtime clock on i2c
+    dtoverlay=i2c-rtc,pcf85063
+
+While this approach does work, it requires knowledge about the hardware design.
+It is more feasible to simplify things for the end user by providing a single
+overlay as it is done the traditional way.
+
+A new overlay can be generated by using ovmerge utility.
+https://github.com/raspberrypi/utils/blob/master/ovmerge/ovmerge
+
+To generate an overlay for the above configuration we pass the configuration
+to ovmerge and add the -c flag.
+
+    ovmerge -c mcp251xfd-overlay.dts,spi0-0,interrupt=25 \
+               mcp251xfd-overlay.dts,spi0-1,interrupt=24 \
+               i2c-rtc-overlay.dts,pcf85063 \
+    >> merged-overlay.dts
+
+The -c option writes the command above as a comment into the overlay as
+a marker that this overlay is generated and how it was generated.
+After compiling the overlay it can be loaded in a single line.
+
+    dtoverlay=merged
+
+It does the same as the original configuration but without parameters.

+
+        N.B. It is recommended to only enable those interfaces that are needed.
+        Leaving all interfaces enabled can lead to unwanted behaviour (i2c_vc
+        interfering with Pi Camera, I2S and SPI hogging GPIO pins, etc.)
+        Note also that i2c, i2c_arm and i2c_vc are aliases for the physical
+        interfaces i2c0 and i2c1. Use of the numeric variants is still possible
+        but deprecated because the ARM/VC assignments differ between board
+        revisions. The same board-specific mapping applies to i2c_baudrate,
+        and the other i2c baudrate parameters.

+Name:   fbtft
+Info:   Overlay for SPI-connected displays using the fbtft drivers.
+
+        This overlay seeks to replace the functionality provided by fbtft_device
+        which is now gone from the kernel.
+
+        Most displays from fbtft_device have been ported over.
+        Example:
+          dtoverlay=fbtft,spi0-0,rpi-display,reset_pin=23,dc_pin=24,led_pin=18,rotate=270
+
+        It is also possible to specify the controller (this will use the default
+        init sequence in the driver).
+        Example:
+          dtoverlay=fbtft,spi0-0,ili9341,bgr,reset_pin=23,dc_pin=24,led_pin=18,rotate=270
+
+        For devices on spi1 or spi2, the interfaces should be enabled
+        with one of the spi1-1/2/3cs and/or spi2-1/2/3cs overlays.
+
+        The following features of fbtft_device have not been ported over:
+        - parallel bus is not supported
+        - the init property which overrides the controller initialization
+          sequence is not supported as a parameter due to memory limitations in
+          the bootloader responsible for applying the overlay.
+
+        See https://github.com/notro/fbtft/wiki/FBTFT-RPI-overlays for how to
+        create an overlay.

+
+Name:   gpio-shutdown
+Info:   Initiates a shutdown when GPIO pin changes. The given GPIO pin
+        is configured as an input key that generates KEY_POWER events.
+
+        This event is handled by systemd-logind by initiating a
+        shutdown. Systemd versions older than 225 need an udev rule
+        enable listening to the input device:
+
+                ACTION!="REMOVE", SUBSYSTEM=="input", KERNEL=="event*", \
+                        SUBSYSTEMS=="platform", DRIVERS=="gpio-keys", \
+                        ATTRS{keys}=="116", TAG+="power-switch"
+
+        Alternatively this event can be handled also on systems without
+        systemd, just by traditional SysV init daemon. KEY_POWER event
+        (keycode 116) needs to be mapped to KeyboardSignal on console
+        and then kb::kbrequest inittab action which is triggered by
+        KeyboardSignal from console can be configured to issue system
+        shutdown. Steps for this configuration are:
+
+            Add following lines to the /etc/console-setup/remap.inc file:
+
+                # Key Power as special keypress
+                keycode 116 = KeyboardSignal
+
+            Then add following lines to /etc/inittab file:
+
+                # Action on special keypress (Key Power)
+                kb::kbrequest:/sbin/shutdown -t1 -a -h -P now
+
+            And finally reload configuration by calling following commands:
+
+                # dpkg-reconfigure console-setup
+                # service console-setup reload
+                # init q
+
+        This overlay only handles shutdown. After shutdown, the system
+        can be powered up again by driving GPIO3 low. The default
+        configuration uses GPIO3 with a pullup, so if you connect a
+        button between GPIO3 and GND (pin 5 and 6 on the 40-pin header),
+        you get a shutdown and power-up button. Please note that
+        Raspberry Pi 1 Model B rev 1 uses GPIO1 instead of GPIO3.

+        N.B.:
+          1) Pin 18 is the only one available on all platforms, and
+             it is the one used by the I2S audio interface.
+             Pins 12 and 13 might be better choices on an A+, B+ or Pi2.
+          2) The onboard analogue audio output uses both PWM channels.
+          3) So be careful mixing audio and PWM.
+          4) Currently the clock must have been enabled and configured
+             by other means.

+Troubleshooting
+===============
+
+If you are experiencing problems that you think are DT-related, enable DT
+diagnostic output by adding this to /boot/config.txt:
+
+    dtdebug=on
+
+and rebooting. Then run:
+
+    sudo vcdbg log msg
+
+and look for relevant messages.

+ * PiFace Digital, Device Tree Overlay.
+ * Copyright (C) 2020 Thomas Preston <thomas.preston@codethink.co.uk>
+ *
+ * The PiFace Digital is a convenient breakout board for the Microchip mcp23s17
+ * SPI GPIO port expander.
+ *
+ * The first eight GPIOs 0..7 (bank A) are connected to eight output terminals
+ * and LEDs, plus two relays on the first two outputs. These output loads are
+ * active-high.
+ *
+ * The next eight GPIOs 8..15 (bank B) are connected to eight input terminals
+ * with four on-board switches connecting them to ground. Inputs devices are
+ * therefore expected to bridge terminals to ground, so the mcp23s17 pullups are
+ * activated for GPIO bank B.
+ *
+ * On PiFace Digital, the mcp23s17 is connected to the Raspberry Pi's SPI0 CS0
+ * bus. Each SPI bus supports up to eight addressable child devices. The PiFace
+ * Digital only supports addresses 0-4, which can be configured by jumpers JP1
+ * and JP2.
+ *
+ * You can tell the driver about these jumper configurations with the
+ * spi-present-mask bitmask:
+ *
+ *     | JP1 | JP2 | dtoverlay line in /boot/config.txt         |
+ *     | --- | --- | ------------------------------------------ |
+ *     |  0  |  0  | dtoverlay=pifacedigital                    |
+ *     |  0  |  0  | dtoverlay=pifacedigital:spi-present-mask=1 |
+ *     |  0  |  1  | dtoverlay=pifacedigital:spi-present-mask=2 |
+ *     |  1  |  0  | dtoverlay=pifacedigital:spi-present-mask=4 |
+ *     |  1  |  1  | dtoverlay=pifacedigital:spi-present-mask=8 |
+ *
+ * # Example
+ * Set the dtoverlay config in /boot/config.txt and power off the Raspberry Pi:
+ *
+ *     $ grep pifacedigital /boot/config.txt
+ *     dtoverlay=pifacedigital
+ *     $ sudo systemctl poweroff
+ *
+ * Attach the PiFace Digital and power on the Raspberry Pi.
+ * Then use the libgpiod tools to query the device:
+ *
+ *     $ sudo apt install gpiod
+ *     $ gpiodetect | grep mcp23s17
+ *     gpiochip2 [mcp23s17.0] (16 lines)
+ *
+ * Set GPIO outputs 0, 2 and 5:
+ *
+ *     $ gpioset gpiochip2 0=1 2=1 5=1
+ *
+ * Get GPIO status (input GPIO 8..15 are high, because they are active-low):
+ *
+ *     $ gpioget gpiochip2 {8..15}
+ *     1 1 1 1 1 1 1 1
+ *
+ * And even monitor interrupts:
+ *
+ *     $ gpiomon gpiochip2 {8..15}
+ *     event: FALLING EDGE offset: 11 timestamp: [1597361662.926741667]
+ *     event:  RISING EDGE offset: 11 timestamp: [1597361663.062555051]

+	 * U-Boot port for Turris Mox has a bug which always expects that "ranges" DT property
+	 * contains exactly 2 ranges with 3 (child) address cells, 2 (parent) address cells and
+	 * 2 size cells and also expects that the second range starts at 16 MB offset. Also it
+	 * expects that first range uses same address for PCI (child) and CPU (parent) cells (so
+	 * no remapping) and that this address is the lowest from all specified ranges. If these
+	 * conditions are not met then U-Boot crashes during loading kernel DTB file. PCIe address
+	 * space is 128 MB long, so the best split between MEM and IO is to use fixed 16 MB window
+	 * for IO and the rest 112 MB (64+32+16) for MEM, despite that maximal IO size is just 64 kB.
+	 * This bug is not present in U-Boot ports for other Armada 3700 devices and is fixed in
+	 * U-Boot version 2021.07. See relevant U-Boot commits (the last one contains fix):
+	 * https://source.denx.de/u-boot/u-boot/-/commit/cb2ddb291ee6fcbddd6d8f4ff49089dfe580f5d7

+	  that may need to compute untrusted bytecode during their
+	  execution. By using pipes or other transports made available to
+	  the process as file descriptors supporting the read/write
+	  syscalls, it's possible to isolate those applications in

+	  and the task is only allowed to execute a few safe syscalls
+	  defined by each seccomp mode.

- * Copyright IBM Corp. 2017, 2018

  * Author(s): Harald Freudenberger
- *
- * The s390_arch_random_generate() function may be called from random.c
- * in interrupt context. So this implementation does the best to be very
- * fast. There is a buffer of random data which is asynchronously checked
- * and filled by a workqueue thread.
- * If there are enough bytes in the buffer the s390_arch_random_generate()
- * just delivers these bytes. Otherwise false is returned until the
- * worker thread refills the buffer.
- * The worker fills the rng buffer by pulling fresh entropy from the
- * high quality (but slow) true hardware random generator. This entropy
- * is then spread over the buffer with an pseudo random generator PRNG.
- * As the arch_get_random_seed_long() fetches 8 bytes and the calling
- * function add_interrupt_randomness() counts this as 1 bit entropy the
- * distribution needs to make sure there is in fact 1 bit entropy contained
- * in 8 bytes of the buffer. The current values pull 32 byte entropy
- * and scatter this into a 2048 byte buffer. So 8 byte in the buffer
- * will contain 1 bit of entropy.
- * The worker thread is rescheduled based on the charge level of the
- * buffer but at least with 500 ms delay to avoid too much CPU consumption.
- * So the max. amount of rng data delivered via arch_get_random_seed is
- * limited to 4k bytes per second.

- * The SMP TLB coherency scheme we use works as follows:

- *    space has (potentially) executed on, this is the heuristic
- *    we use to avoid doing cross calls.

- *    cross calls.
- *
- *    One invariant is that when a cpu switches to a process, and
- *    that processes tsk->active_mm->cpu_vm_mask does not have the
- *    current cpu's bit set, that tlb context is flushed locally.
- *
- *    If the address space is non-shared (ie. mm->count == 1) we avoid
- *    cross calls when we want to flush the currently running process's

- *    flush locally only.  This will force any subsequent cpus which run
- *    this task to flush the context from the local tlb if the process
- *    migrates to another cpu (again).
- *
- * 3) For shared address spaces (threads) and swapping we bite the
- *    bullet for most cases and perform the cross call (but only to
- *    the cpus listed in cpu_vm_mask).
- *
- *    The performance gain from "optimizing" away the cross call for threads is
- *    questionable (in theory the big win for threads is the massive sharing of

+ *
+ * AMD RAPL interface for Fam17h is described in the public PPR:
+ * https://bugzilla.kernel.org/show_bug.cgi?id=206537
+ *
+ * RAPL provides more controls than just reporting energy consumption
+ * however here we only expose the 3 energy consumption free running
+ * counters (pp0, pkg, dram).
+ *
+ * Each of those counters increments in a power unit defined by the
+ * RAPL_POWER_UNIT MSR. On SandyBridge, this unit is 1/(2^16) Joules
+ * but it can vary.
+ *
+ * Counter to rapl events mappings:
+ *
+ *  pp0 counter: consumption of all physical cores (power plane 0)
+ * 	  event: rapl_energy_cores
+ *    perf code: 0x1
+ *
+ *  pkg counter: consumption of the whole processor package
+ *	  event: rapl_energy_pkg
+ *    perf code: 0x2
+ *
+ * dram counter: consumption of the dram domain (servers only)
+ *	  event: rapl_energy_dram
+ *    perf code: 0x3
+ *
+ * gpu counter: consumption of the builtin-gpu domain (client only)
+ *	  event: rapl_energy_gpu
+ *    perf code: 0x4
+ *
+ *  psys counter: consumption of the builtin-psys domain (client only)
+ *	  event: rapl_energy_psys
+ *    perf code: 0x5
+ *
+ * We manage those counters as free running (read-only). They may be
+ * use simultaneously by other tools, such as turbostat.
+ *
+ * The events only support system-wide mode counting. There is no
+ * sampling support because it does not make sense and is not
+ * supported by the RAPL hardware.
+ *
+ * Because we want to avoid floating-point operations in the kernel,
+ * the events are all reported in fixed point arithmetic (32.32).
+ * Tools must adjust the counts to convert them to Watts using
+ * the duration of the measurement. Tools may use a function such as
+ * ldexp(raw_count, -32);

+==================
+Config Annotations
+==================
+
+:Author: Andrea Righi
+
+Overview
+========
+
+Each Ubuntu kernel needs to maintain its own .config for each supported
+architecture and each flavour.
+
+Every time a new patch is applied or a kernel is rebased on top of a new
+one, we need to update the .config's accordingly (config options can be
+added, removed and also renamed).
+
+So, we need to make sure that some critical config options are always
+matching the desired value in order to have a functional kernel.
+
+State of the art
+================
+
+At the moment configs are maintained as a set of Kconfig chunks (inside
+`debian.<kernel>/config/`): a global one, plus per-arch / per-flavour
+chunks.
+
+In addition to that, we need to maintain also a file called
+'annotations'; the purpose of this file is to make sure that some
+critical config options are not silently removed or changed when the
+real .config is re-generated (for example after a rebase or after
+applying a new set of patches).
+
+The main problem with this approach is that, often, we have duplicate
+information that is stored both in the Kconfig chunks *and* in the
+annotations files and, at the same time, the whole .config's information
+is distributed between Kconfig chunks and annotations, making it hard to
+maintain, review and manage in general.
+
+Proposed solution
+=================
+
+The proposed solution is to store all the config information into the
+"annotations" format and get rid of the config chunks (basically the
+real .config's can be produced "compiling" annotations).
+
+Implementation
+==============
+
+To help the management of the annotations an helper script is provided
+(`debian/scripts/misc/annotations`):
+
+```
+usage: annotations [-h] [--version] [--file FILE] [--arch ARCH] [--flavour FLAVOUR] [--config CONFIG]
+                   (--query | --export | --import FILE | --update FILE | --check FILE)
+
+Manage Ubuntu kernel .config and annotations
+
+options:
+  -h, --help            show this help message and exit
+  --version, -v         show program's version number and exit
+  --file FILE, -f FILE  Pass annotations or .config file to be parsed
+  --arch ARCH, -a ARCH  Select architecture
+  --flavour FLAVOUR, -l FLAVOUR
+                        Select flavour (default is "generic")
+  --config CONFIG, -c CONFIG
+                        Select a specific config option
+
+Action:
+  --query, -q           Query annotations
+  --export, -e          Convert annotations to .config format
+  --import FILE, -i FILE
+                        Import a full .config for a specific arch and flavour into annotations
+  --update FILE, -u FILE
+                        Import a partial .config into annotations (only resync configs specified in FILE)
+  --check FILE, -k FILE
+                        Validate kernel .config with annotations
+```
+
+This script allows to query config settings (per arch/flavour/config),
+export them into the Kconfig format (generating the real .config files)
+and check if the final .config matches the rules defined in the
+annotations.
+
+Examples (annotations is defined as an alias to `debian/scripts/annotations`):
+
+ - Show settings for `CONFIG_DEBUG_INFO_BTF` for master kernel across all the
+   supported architectures and flavours:
+
+```
+$ annotations --query --config CONFIG_DEBUG_INFO_BTF
+{
+    "policy": {
+        "amd64": "y",
+        "arm64": "y",
+        "armhf": "n",
+        "ppc64el": "y",
+        "riscv64": "y",
+        "s390x": "y"
+    },
+    "note": "'Needs newer pahole for armhf'"
+}
+```
+
+ - Dump kernel .config for arm64 and flavour generic-64k:
+
+```
+$ annotations --arch arm64 --flavour generic-64k --export
+CONFIG_DEBUG_FS=y
+CONFIG_DEBUG_KERNEL=y
+CONFIG_COMPAT=y
+...
+```
+
+ - Update annotations file with a new kernel .config for amd64 flavour
+   generic:
+
+```
+$ annotations --arch amd64 --flavour generic --import build/.config
+```
+
+Moreover, an additional kernelconfig commands are provided
+(via debian/rules targets):
+ - `migrateconfigs`: automatically merge all the previous configs into
+   annotations (local changes still need to be committed)
+
+Annotations headers
+===================
+
+The main annotations file should contain a header to define the architectures
+and flavours that are supported.
+
+Here is the format of the header for the generic kernel:
+```
+# Menu: HEADER
+# FORMAT: 4
+# ARCH: amd64 arm64 armhf ppc64el riscv64 s390x
+# FLAVOUR: amd64-generic arm64-generic arm64-generic-64k armhf-generic armhf-generic-lpae ppc64el-generic riscv64-generic s390x-generic
+
+```
+
+Example header of a derivative (linux-aws):
+```
+# Menu: HEADER
+# FORMAT: 4

+```
+
+Pros and Cons
+=============
+
+ Pros:
+  - avoid duplicate information in .config's and annotations
+  - allow to easily define groups of config settings (for a specific
+    environment or feature, such as annotations.clouds, annotations.ubuntu,
+    annotations.snapd, etc.)
+  - config options are more accessible, easy to change and review
+  - we can easily document how config options are managed (and external
+    contributors won't be discouraged anymore when they need to to change a
+    config option)
+
+ Cons:
+  - potential regressions: the new tool/scripts can have potential bugs,
+    so we could experience regressions due to some missed config changes
+  - kernel team need to understand the new process (even if everything
+    is transparent, kernel cranking process is the same, there might be
+    corner cases that need to be addressed and resolved manually)
+
+TODO
+====
+
+ - Migrate all flavour and arch definitions into annotations (rather
+   than having this information defined in multiple places inside
+   debian/scripts); right now this information is "partially" migrated,
+   meaning that we need to define arches and flavours in the headers
+   section of annotations (so that the annotations tool can figure out
+   the list of supported arches and flavours), but arches and flavours
+   are still defined elsewhere, ideally we would like to have arches and
+   flavours defined only in one place: annotations.

+Description: Linux kernel source for version PKGVER with Ubuntu patches
+ This package provides the source code for the Linux kernel version
+ PKGVER.
+ .
+ This package is mainly meant for other packages to use, in order to build
+ custom flavours.
+ .
+ If you wish to use this package to create a custom Linux kernel, then it
+ is suggested that you investigate the package kernel-package, which has
+ been designed to ease the task of creating kernel image packages.
+ .
+ If you are simply trying to build third-party modules for your kernel,
+ you do not want this package. Install the appropriate linux-headers
+ package instead.

+This README describes the reason for, and the use of, module
+inclusion lists.
+
+The original Hardy release had the notion of sub-flavours,
+e.g., a flavour that was constructed as a subset of an existing flavour.
+For example, the virtual flavour was extracted from the server flavour using
+a subset of the server flavour modules. However, there were some difficult
+mainteneance issues with regard to packaging, make rules, and scripts. This
+re-implementation of the sub-flavours philosophy is hopefully simpler,
+and retrofitable to all releases.
+
+A module inclusion list looks at the problem of of constructing a package
+from the perspective of what modules do we _want_ in the package, as opposed
+to what modules we _don't_ want. As the kernel matures, more and more devices are added
+which makes the problem of configuration maintenance a real pain in the ass.
+If we took the approach of disabling all of the config options that we don't want,
+then the differences between flavours will quickly become quite large, making
+it difficult to quickly compare the individual flavour configs.  Each time a
+new config option is added then we also have to make a decision about disabling in
+order to continue to keep the minimal number of modules.
+
+A module inclusion list is applied on a per-flavour basis. For example,
+debian.<BRANCH>/control.d/${flavour}.inclusion-list. For example, the
+config for virtual is very close to server and generic, but the inclusion list
+causes the virtual package to be constructed with _only_ the modules described 
+in the inclusion list.
+
+The inclusion list format is a simple bash regular expression list of files. For example,
+
+arch/*/{crypto,kernel,oprofile}
+drivers/acpi/*
+drivers/ata/ahci.ko
+
+These 3 regular expression forms are suitable for expansion by bash and as inputs to 'find'.
+See debian/scripts/module-inclusion for details.
+
+There are 2 log files created as a side effect of the application of the module
+inclusion list; $(flavour).inclusion-list.log and $(flavour).depmod.log.
+
+$(flavour).inclusion-list.log : This log is created while the inclusion list
+modules are being copied. If any are missing, then those warnings go in this log.
+While its not considered a fatal error, you should endevour to correct your inclusion
+list such that there are no missing modules.
+
+$(flavour).depmod.log : The log is created as a result of running depmod on the
+resulting set of modules. If there are missing symbols then you'll find that information
+here. Again, you should modify your inclusion list such that there are no missing
+symbols.

+
+DPKG_ARCH     : The dpkg architecture (e.g. "amd64")
+KERN_ARCH     : The kernel architecture (e.g. "x86_64")

+PREV_REVISION : The revision prior to this one
+ABI_NUM       : The specific ABI number for this build (e.g. 2)

+BUILD_DIR     : The directory where this build took place
+INSTALL_DIR   : The directory where the package is prepared
+SOURCE_DIR    : Where the main kernel source is
+
+Scripts are expected to have a zero exit status when no problems occur,
+and non-zero when an error occurs that should stop the build. Scripts
+should print whatever info they deem needed to deduce the problem.

- * (now, with legal B.S. out of the way.....)
- *
- * This routine gathers environmental noise from device drivers, etc.,
- * and returns good random numbers, suitable for cryptographic use.
- * Besides the obvious cryptographic uses, these numbers are also good
- * for seeding TCP sequence numbers, and other places where it is
- * desirable to have numbers which are not only random, but hard to
- * predict by an attacker.
- *
- * Theory of operation
- * ===================
- *
- * Computers are very predictable devices.  Hence it is extremely hard
- * to produce truly random numbers on a computer --- as opposed to
- * pseudo-random numbers, which can easily generated by using a
- * algorithm.  Unfortunately, it is very easy for attackers to guess
- * the sequence of pseudo-random number generators, and for some
- * applications this is not acceptable.  So instead, we must try to
- * gather "environmental noise" from the computer's environment, which
- * must be hard for outside attackers to observe, and use that to
- * generate random numbers.  In a Unix environment, this is best done
- * from inside the kernel.
- *
- * Sources of randomness from the environment include inter-keyboard
- * timings, inter-interrupt timings from some interrupts, and other
- * events which are both (a) non-deterministic and (b) hard for an
- * outside observer to measure.  Randomness from these sources are
- * added to an "entropy pool", which is mixed using a CRC-like function.
- * This is not cryptographically strong, but it is adequate assuming
- * the randomness is not chosen maliciously, and it is fast enough that
- * the overhead of doing it on every interrupt is very reasonable.
- * As random bytes are mixed into the entropy pool, the routines keep
- * an *estimate* of how many bits of randomness have been stored into
- * the random number generator's internal state.
- *
- * When random bytes are desired, they are obtained by taking the SHA
- * hash of the contents of the "entropy pool".  The SHA hash avoids
- * exposing the internal state of the entropy pool.  It is believed to
- * be computationally infeasible to derive any useful information
- * about the input of SHA from its output.  Even if it is possible to
- * analyze SHA in some clever way, as long as the amount of data
- * returned from the generator is less than the inherent entropy in
- * the pool, the output data is totally unpredictable.  For this
- * reason, the routine decreases its internal estimate of how many
- * bits of "true randomness" are contained in the entropy pool as it
- * outputs random numbers.
- *
- * If this estimate goes to zero, the routine can still generate
- * random numbers; however, an attacker may (at least in theory) be
- * able to infer the future output of the generator from prior
- * outputs.  This requires successful cryptanalysis of SHA, which is
- * not believed to be feasible, but there is a remote possibility.
- * Nonetheless, these numbers should be useful for the vast majority
- * of purposes.
- *
- * Exported interfaces ---- output
- * ===============================
- *
- * There are four exported interfaces; two for use within the kernel,
- * and two or use from userspace.
- *
- * Exported interfaces ---- userspace output
- * -----------------------------------------

- * The userspace interfaces are two character devices /dev/random and
- * /dev/urandom.  /dev/random is suitable for use when very high
- * quality randomness is desired (for example, for key generation or
- * one-time pads), as it will only return a maximum of the number of
- * bits of randomness (as estimated by the random number generator)
- * contained in the entropy pool.
- *
- * The /dev/urandom device does not have this limit, and will return
- * as many bytes as are requested.  As more and more random bytes are
- * requested without giving time for the entropy pool to recharge,
- * this will result in random numbers that are merely cryptographically
- * strong.  For many applications, however, this is acceptable.
- *
- * Exported interfaces ---- kernel output
- * --------------------------------------
- *
- * The primary kernel interface is
- *
- * 	void get_random_bytes(void *buf, int nbytes);
- *
- * This interface will return the requested number of random bytes,
- * and place it in the requested buffer.  This is equivalent to a
- * read from /dev/urandom.
- *
- * For less critical applications, there are the functions:
- *
- * 	u32 get_random_u32()
- * 	u64 get_random_u64()
- * 	unsigned int get_random_int()
- * 	unsigned long get_random_long()
- *
- * These are produced by a cryptographic RNG seeded from get_random_bytes,
- * and so do not deplete the entropy pool as much.  These are recommended
- * for most in-kernel operations *if the result is going to be stored in
- * the kernel*.
- *
- * Specifically, the get_random_int() family do not attempt to do
- * "anti-backtracking".  If you capture the state of the kernel (e.g.
- * by snapshotting the VM), you can figure out previous get_random_int()
- * return values.  But if the value is stored in the kernel anyway,
- * this is not a problem.
- *
- * It *is* safe to expose get_random_int() output to attackers (e.g. as
- * network cookies); given outputs 1..n, it's not feasible to predict
- * outputs 0 or n+1.  The only concern is an attacker who breaks into
- * the kernel later; the get_random_int() engine is not reseeded as
- * often as the get_random_bytes() one.
- *
- * get_random_bytes() is needed for keys that need to stay secret after
- * they are erased from the kernel.  For example, any key that will
- * be wrapped and stored encrypted.  And session encryption keys: we'd
- * like to know that after the session is closed and the keys erased,
- * the plaintext is unrecoverable to someone who recorded the ciphertext.
- *
- * But for network ports/cookies, stack canaries, PRNG seeds, address
- * space layout randomization, session *authentication* keys, or other
- * applications where the sensitive data is stored in the kernel in
- * plaintext for as long as it's sensitive, the get_random_int() family
- * is just fine.
- *
- * Consider ASLR.  We want to keep the address space secret from an
- * outside attacker while the process is running, but once the address
- * space is torn down, it's of no use to an attacker any more.  And it's
- * stored in kernel data structures as long as it's alive, so worrying
- * about an attacker's ability to extrapolate it from the get_random_int()
- * CRNG is silly.
- *
- * Even some cryptographic keys are safe to generate with get_random_int().
- * In particular, keys for SipHash are generally fine.  Here, knowledge
- * of the key authorizes you to do something to a kernel object (inject
- * packets to a network connection, or flood a hash table), and the
- * key is stored with the object being protected.  Once it goes away,
- * we no longer care if anyone knows the key.
- *
- * prandom_u32()
- * -------------
- *
- * For even weaker applications, see the pseudorandom generator
- * prandom_u32(), prandom_max(), and prandom_bytes().  If the random
- * numbers aren't security-critical at all, these are *far* cheaper.
- * Useful for self-tests, random error simulation, randomized backoffs,
- * and any other application where you trust that nobody is trying to
- * maliciously mess with you by guessing the "random" numbers.
- *
- * Exported interfaces ---- input
- * ==============================
- *
- * The current exported interfaces for gathering environmental noise
- * from the devices are:
- *
- *	void add_device_randomness(const void *buf, unsigned int size);
- * 	void add_input_randomness(unsigned int type, unsigned int code,
- *                                unsigned int value);
- *	void add_interrupt_randomness(int irq, int irq_flags);
- * 	void add_disk_randomness(struct gendisk *disk);
- *
- * add_device_randomness() is for adding data to the random pool that
- * is likely to differ between two devices (or possibly even per boot).
- * This would be things like MAC addresses or serial numbers, or the
- * read-out of the RTC. This does *not* add any actual entropy to the
- * pool, but it initializes the pool to different values for devices
- * that might otherwise be identical and have very little entropy
- * available to them (particularly common in the embedded world).
- *
- * add_input_randomness() uses the input layer interrupt timing, as well as
- * the event type information from the hardware.
- *
- * add_interrupt_randomness() uses the interrupt timing as random
- * inputs to the entropy pool. Using the cycle counters and the irq source
- * as inputs, it feeds the randomness roughly once a second.
- *
- * add_disk_randomness() uses what amounts to the seek time of block
- * layer request events, on a per-disk_devt basis, as input to the
- * entropy pool. Note that high-speed solid state drives with very low
- * seek times do not make for good sources of entropy, as their seek
- * times are usually fairly consistent.
+ * This driver produces cryptographically secure pseudorandom data. It is divided
+ * into roughly six sections, each with a section header:
  *
- * All of these routines try to estimate how many bits of randomness a
- * particular randomness source.  They do this by keeping track of the
- * first and second order deltas of the event timings.
- *
- * Ensuring unpredictability at system startup
- * ============================================
- *
- * When any operating system starts up, it will go through a sequence
- * of actions that are fairly predictable by an adversary, especially
- * if the start-up does not involve interaction with a human operator.
- * This reduces the actual number of bits of unpredictability in the
- * entropy pool below the value in entropy_count.  In order to
- * counteract this effect, it helps to carry information in the
- * entropy pool across shut-downs and start-ups.  To do this, put the
- * following lines an appropriate script which is run during the boot
- * sequence:
- *
- *	echo "Initializing random number generator..."
- *	random_seed=/var/run/random-seed
- *	# Carry a random seed from start-up to start-up
- *	# Load and then save the whole entropy pool
- *	if [ -f $random_seed ]; then
- *		cat $random_seed >/dev/urandom
- *	else
- *		touch $random_seed
- *	fi
- *	chmod 600 $random_seed
- *	dd if=/dev/urandom of=$random_seed count=1 bs=512
- *
- * and the following lines in an appropriate script which is run as
- * the system is shutdown:
- *
- *	# Carry a random seed from shut-down to start-up
- *	# Save the whole entropy pool
- *	echo "Saving random seed..."
- *	random_seed=/var/run/random-seed
- *	touch $random_seed
- *	chmod 600 $random_seed
- *	dd if=/dev/urandom of=$random_seed count=1 bs=512
- *
- * For example, on most modern systems using the System V init
- * scripts, such code fragments would be found in
- * /etc/rc.d/init.d/random.  On older Linux systems, the correct script
- * location might be in /etc/rcb.d/rc.local or /etc/rc.d/rc.0.
- *
- * Effectively, these commands cause the contents of the entropy pool
- * to be saved at shut-down time and reloaded into the entropy pool at
- * start-up.  (The 'dd' in the addition to the bootup script is to
- * make sure that /etc/random-seed is different for every start-up,
- * even if the system crashes without executing rc.0.)  Even with
- * complete knowledge of the start-up activities, predicting the state
- * of the entropy pool requires knowledge of the previous history of
- * the system.
- *
- * Configuring the /dev/random driver under Linux
- * ==============================================
- *
- * The /dev/random driver under Linux uses minor numbers 8 and 9 of
- * the /dev/mem major number (#1).  So if your system does not have
- * /dev/random and /dev/urandom created already, they can be created
- * by using the commands:
- *
- * 	mknod /dev/random c 1 8
- * 	mknod /dev/urandom c 1 9
- *
- * Acknowledgements:
- * =================
- *
- * Ideas for constructing this random number generator were derived
- * from Pretty Good Privacy's random number generator, and from private
- * discussions with Phil Karn.  Colin Plumb provided a faster random
- * number generator, which speed up the mixing function of the entropy
- * pool, taken from PGPfone.  Dale Worley has also contributed many
- * useful ideas and suggestions to improve this driver.
- *
- * Any flaws in the design are solely my responsibility, and should
- * not be attributed to the Phil, Colin, or any of authors of PGP.
- *
- * Further background information on this topic may be obtained from
- * RFC 1750, "Randomness Recommendations for Security", by Donald
- * Eastlake, Steve Crocker, and Jeff Schiller.
+ *   - Initialization and readiness waiting.
+ *   - Fast key erasure RNG, the "crng".
+ *   - Entropy accumulation and extraction routines.
+ *   - Entropy collection routines.
+ *   - Userspace reader/writer interfaces.
+ *   - Sysctl interface.
+ *
+ * The high level overview is that there is one input pool, into which
+ * various pieces of data are hashed. Prior to initialization, some of that
+ * data is then "credited" as having a certain number of bits of entropy.
+ * When enough bits of entropy are available, the hash is finalized and
+ * handed as a key to a stream cipher that expands it indefinitely for
+ * various consumers. This key is periodically refreshed as the various
+ * entropy collectors, described below, add data to the input pool.

- * Thanks to Colin Plumb for suggesting this.

- * The mixing operation is much less sensitive than the output hash,
- * where we use SHA-1.  All that we want of mixing operation is that
- * it be a good non-cryptographic hash; i.e. it not produce collisions
- * when fed "random" data of the sort we expect to see.  As long as
- * the pool state differs for different inputs, we have preserved the
- * input entropy and done a good job.  The fact that an intelligent
- * attacker can construct inputs that will produce controlled
- * alterations to the pool's state is not important because we don't
- * consider such inputs to contribute any randomness.  The only
- * property we need with respect to them is that the attacker can't
- * increase his/her knowledge of the pool's state.  Since all
- * additions are reversible (knowing the final state and the input,
- * you can reconstruct the initial state), if an attacker has any
- * uncertainty about the initial state, he/she can only shuffle that
- * uncertainty about, but never cause any collisions (which would
- * decrease the uncertainty).
- *
- * Our mixing functions were analyzed by Lacharme, Roeck, Strubel, and
- * Videau in their paper, "The Linux Pseudorandom Number Generator
- * Revisited" (see: http://eprint.iacr.org/2012/251.pdf).  In their
- * paper, they point out that we are not using a true Twisted GFSR,
- * since Matsumoto & Kurita used a trinomial feedback polynomial (that
- * is, with only three taps, instead of the six that we are using).
- * As a result, the resulting polynomial is neither primitive nor
- * irreducible, and hence does not have a maximal period over
- * GF(2**32).  They suggest a slight change to the generator
- * polynomial which improves the resulting TGFSR polynomial to be
- * irreducible, which we have made here.

+ *
+ * add_device_randomness() adds data to the input pool that
+ * is likely to differ between two devices (or possibly even per boot).
+ * This would be things like MAC addresses or serial numbers, or the
+ * read-out of the RTC. This does *not* credit any actual entropy to
+ * the pool, but it initializes the pool to different values for devices
+ * that might otherwise be identical and have very little entropy
+ * available to them (particularly common in the embedded world).
+ *
+ * add_hwgenerator_randomness() is for true hardware RNGs, and will credit
+ * entropy as specified by the caller. If the entropy pool is full it will
+ * block until more entropy is needed.
+ *
+ * add_bootloader_randomness() is called by bootloader drivers, such as EFI
+ * and device tree, and credits its input depending on whether or not the
+ * configuration option CONFIG_RANDOM_TRUST_BOOTLOADER is set.
+ *
+ * add_interrupt_randomness() uses the interrupt timing as random
+ * inputs to the entropy pool. Using the cycle counters and the irq source
+ * as inputs, it feeds the input pool roughly once a second or after 64
+ * interrupts, crediting 1 bit of entropy for whichever comes first.
+ *
+ * add_input_randomness() uses the input layer interrupt timing, as well
+ * as the event type information from the hardware.
+ *
+ * add_disk_randomness() uses what amounts to the seek time of block
+ * layer request events, on a per-disk_devt basis, as input to the
+ * entropy pool. Note that high-speed solid state drives with very low
+ * seek times do not make for good sources of entropy, as their seek
+ * times are usually fairly consistent.
+ *
+ * The last two routines try to estimate how many bits of entropy
+ * to credit. They do this by keeping track of the first and second
+ * order deltas of the event timings.

+ * the LINUX_EFI_MOK_VARIABLE_TABLE_GUID.
+ *
+ * This EFI configuration table provides a more robust alternative to

+ * more authoritative.
+ *
+ * This module includes code that validates and maps the EFI MOK table,
+ * if it's presence was detected very early in boot.
+ *
+ * Kernel interface routines are provided to walk through all the
+ * entries in the MOK config table or to search for a specific named
+ * entry.
+ *
+ * The contents of the individual named MOK config table entries are

+	 * step 4: apply_ctx_for_surface - program dchubp
+	 * step 5: pipe_control_lock(false) - dchubp register change take effect
+	 * step 6: optimize_bandwidth --> dc_post_update_surfaces_to_stream
+	 * for full_date, optimize clock to save power
+	 *
+	 * at end of step 1, dcn clocks (dprefclk, dispclk, dppclk) may be
+	 * changed for new dchubp configuration. but real dcn hub dchubps are
+	 * still running with old configuration until end of step 5. this need
+	 * clocks settings at step 1 should not less than that before step 1.

+	 * new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz)
+	 * 2. request_dpp_div = new_clocks->dispclk_khz > new_clocks->dppclk_khz
+	 *
+	 * the second condition is based on new dchubp configuration. dppclk
+	 * for new dchubp may be different from dppclk before step 1.
+	 * for example, before step 1, dchubps are as below:
+	 * pipe 0: recout=(0,40,1920,980) viewport=(0,0,1920,979)
+	 * pipe 1: recout=(0,0,1920,1080) viewport=(0,0,1920,1080)
+	 * for dppclk for pipe0 need dppclk = dispclk

+	 * new dchubp pipe split configuration:
+	 * pipe 0: recout=(0,0,960,1080) viewport=(0,0,960,1080)
+	 * pipe 1: recout=(960,0,960,1080) viewport=(960,0,960,1080)
+	 * dppclk only needs dppclk = dispclk /2.
+	 *
+	 * dispclk, dppclk are not lock by otg master lock. they take effect
+	 * after step 1. during this transition, dispclk are the same, but
+	 * dppclk is changed to half of previous clock for old dchubp
+	 * configuration between step 1 and step 6. This may cause p-state
+	 * warning intermittently.
+	 *
+	 * for new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz, we

+ * On some Intel PCIe bridge controllers doing a

+ * Skipping the intermediate D3hot step seems to make it work again. This is
+ * probably caused by not meeting the expectation the involved AML code has
+ * when the GPU is put into D3hot state before invoking it.
+ *
+ * This leads to various manifestations of this issue:
+ *  - AML code execution to power on the GPU hits an infinite loop (as the
+ *    code waits on device memory to change).
+ *  - kernel crashes, as all PCI reads return -1, which most code isn't able
+ *    to handle well enough.
+ *
+ * In all cases dmesg will contain at least one line like this:
+ * 'nouveau 0000:01:00.0: Refused to change power state, currently in D3'
+ * followed by a lot of nouveau timeouts.
+ *
+ * In the \_SB.PCI0.PEG0.PG00._OFF code deeper down writes bit 0x80 to the not
+ * documented PCI config space register 0x248 of the Intel PCIe bridge
+ * controller (0x1901) in order to change the state of the PCIe link between
+ * the PCIe port and the GPU. There are alternative code paths using other
+ * registers, which seem to work fine (executed pre Windows 8):
+ *  - 0xbc bit 0x20 (publicly available documentation claims 'reserved')
+ *  - 0xb0 bit 0x10 (link disable)
+ * Changing the conditions inside the firmware by poking into the relevant
+ * addresses does resolve the issue, but it seemed to be ACPI private memory
+ * and not any device accessible memory at all, so there is no portable way of
+ * changing the conditions.
+ * On a XPS 9560 that means bits [0,3] on \CPEX need to be cleared.
+ *
+ * The only systems where this behavior can be seen are hybrid graphics laptops
+ * with a secondary Nvidia Maxwell, Pascal or Turing GPU. It's unclear whether
+ * this issue only occurs in combination with listed Intel PCIe bridge
+ * controllers and the mentioned GPUs or other devices as well.
+ *
+ * documentation on the PCIe bridge controller can be found in the
+ * "7th Generation Intel® Processor Families for H Platforms Datasheet Volume 2"
+ * Section "12 PCI Express* Controller (x16) Registers"

+ * initialize the sensor over I2C, and then exit the software standby.
+ *
+ * This start-up time can be optimized a bit more, if we start the writes
+ * over I2C after (t4+t6), but before (t4+t5) expires. But then sensor
+ * initialization over I2C may complete before (t4+t5) expires, and we must
+ * ensure that capture is not started before (t4+t5).
+ *
+ * This delay doesn't account for the power supply startup time. If needed,

+ *
+ * Copyright (C) 2017-2020 - Raspberry Pi (Trading) Ltd.
+ *
+ * Dave Stevenson <dave.stevenson@raspberrypi.com>
+ *
+ * Based on TI am437x driver by
+ *   Benoit Parrot <bparrot@ti.com>
+ *   Lad, Prabhakar <prabhakar.csengg@gmail.com>
+ *
+ * and TI CAL camera interface driver by
+ *    Benoit Parrot <bparrot@ti.com>
+ *
+ *
+ * There are two camera drivers in the kernel for BCM283x - this one
+ * and bcm2835-camera (currently in staging).
+ *
+ * This driver directly controls the Unicam peripheral - there is no
+ * involvement with the VideoCore firmware. Unicam receives CSI-2 or
+ * CCP2 data and writes it into SDRAM.
+ * The only potential processing options are to repack Bayer data into an
+ * alternate format, and applying windowing.
+ * The repacking does not shift the data, so can repack V4L2_PIX_FMT_Sxxxx10P
+ * to V4L2_PIX_FMT_Sxxxx10, or V4L2_PIX_FMT_Sxxxx12P to V4L2_PIX_FMT_Sxxxx12,
+ * but not generically up to V4L2_PIX_FMT_Sxxxx16. The driver will add both
+ * formats where the relevant formats are defined, and will automatically
+ * configure the repacking as required.
+ * Support for windowing may be added later.
+ *
+ * It should be possible to connect this driver to any sensor with a
+ * suitable output interface and V4L2 subdevice driver.
+ *
+ * bcm2835-camera uses the VideoCore firmware to control the sensor,
+ * Unicam, ISP, and all tuner control loops. Fully processed frames are
+ * delivered to the driver by the firmware. It only has sensor drivers
+ * for Omnivision OV5647, and Sony IMX219 sensors.
+ *
+ * The two drivers are mutually exclusive for the same Unicam instance.
+ * The VideoCore firmware checks the device tree configuration during boot.
+ * If it finds device tree nodes called csi0 or csi1 it will block the
+ * firmware from accessing the peripheral, and bcm2835-camera will
+ * not be able to stream data.

+	 *    a) The clock divisor for SDR12, SDR25, and SDR50 is too small.
+	 *       This results in clock frequencies that are 2x higher than
+	 *       acceptable. i.e., SDR12 = 25 MHz, SDR25 = 50 MHz, SDR50 =
+	 *       100 MHz.x
+	 *    b) The HS200 and HS400 driver strengths don't match.
+	 *       By default, the SDR104 preset register has a driver strength of
+	 *       A, but the (internal) HS400 preset register has a driver
+	 *       strength of B. As part of initializing HS400, HS200 tuning
+	 *       needs to be performed. Having different driver strengths
+	 *       between tuning and operation is wrong. It results in different
+	 *       rise/fall times that lead to incorrect sampling.
+	 * 2) Firmware with properly initialized presets.
+	 *    These presets have proper clock divisors. i.e., SDR12 => 12MHz,
+	 *    SDR25 => 25 MHz, SDR50 => 50 MHz. Additionally the HS200 and
+	 *    HS400 preset driver strengths match.
+	 *
+	 *    Enabling presets for HS400 doesn't work for the following reasons:
+	 *    1) sdhci_set_ios has a hard coded list of timings that are used
+	 *       to determine if presets should be enabled.
+	 *    2) sdhci_get_preset_value is using a non-standard register to
+	 *       read out HS400 presets. The AMD controller doesn't support this
+	 *       non-standard register. In fact, it doesn't expose the HS400
+	 *       preset register anywhere in the SDHCI memory map. This results
+	 *       in reading a garbage value and using the wrong presets.
+	 *
+	 *       Since HS400 and HS200 presets must be identical, we could
+	 *       instead use the the SDR104 preset register.
+	 *
+	 *    If the above issues are resolved we could remove this quirk for
+	 *    firmware that that has valid presets (i.e., SDR12 <= 12 MHz).

+		DPAA FMan erratum A050385 software workaround implementation:
+		align buffers, data start, SG fragment length to avoid FMan DMA
+		splits.
+		FMAN DMA read or writes under heavy traffic load may cause FMAN
+		internal resource leak thus stopping further packet processing.
+		The FMAN internal queue can overflow when FMAN splits single
+		read or write transactions into multiple smaller transactions
+		such that more than 17 AXI transactions are in flight from FMAN
+		to interconnect. When the FMAN internal queue overflows, it can
+		stall further packet processing. The issue can occur with any
+		one of the following three conditions:
+		1. FMAN AXI transaction crosses 4K address boundary (Errata
+		A010022)
+		2. FMAN DMA address for an AXI transaction is not 16 byte
+		aligned, i.e. the last 4 bits of an address are non-zero
+		3. Scatter Gather (SG) frames have more than one SG buffer in
+		the SG list and any one of the buffers, except the last
+		buffer in the SG list has data size that is not a multiple
+		of 16 bytes, i.e., other than 16, 32, 48, 64, etc.
+		With any one of the above three conditions present, there is
+		likelihood of stalled FMAN packet processing, especially under
+		stress with multiple ports injecting line-rate traffic.

-/* Locking scheme -
- * The shared resource which needs to be protected is realdev->rx_handler_data.
- * For the writer path, this is using rtnl_lock(). The writer paths are
- * rmnet_newlink(), rmnet_dellink() and rmnet_force_unassociate_device(). These
- * paths are already called with rtnl_lock() acquired in. There is also an
- * ASSERT_RTNL() to ensure that we are calling with rtnl acquired. For
- * dereference here, we will need to use rtnl_dereference(). Dev list writing
- * needs to happen with rtnl_lock() acquired for netdev_master_upper_dev_link().
- * For the reader path, the real_dev->rx_handler_data is called in the TX / RX
- * path. We only need rcu_read_lock() for these scenarios. In these cases,
- * the rcu_read_lock() is held in __dev_queue_xmit() and
- * netif_receive_skb_internal(), so readers need to use rcu_dereference_rtnl()
- * to get the relevant information. For dev list reading, we again acquire
- * rcu_read_lock() in rmnet_dellink() for netdev_master_upper_dev_get_rcu().
- * We also use unregister_netdevice_many() to free all rmnet devices in
- * rmnet_force_unassociate_device() so we dont lose the rtnl_lock() and free in
- * same context.

+ *    Upgraded it to 2.1.43
+ * Francois-Rene Rideau <fare@tunes.org> 19971012
+ *    Upgraded it to 2.1.57
+ *    to please Linus T., replaced huge #ifdef's between little/big endian
+ *    by nestedly #include'd files.
+ * Francois-Rene Rideau <fare@tunes.org> 19971205
+ *    Made it to 2.1.71; now a facelift:
+ *    Put files under include/linux/byteorder/
+ *    Split swab from generic support.
+ *
+ * TODO:
+ *   = Regular kernel maintainers could also replace all these manual
+ *    byteswap macros that remain, disseminated among drivers,
+ *    after some grep or the sources...
+ *   = Linus might want to rename all these macros and files to fit his taste,
+ *    to fit his personal naming scheme.
+ *   = it seems that a few drivers would also appreciate
+ *    nybble swapping support...
+ *   = every architecture could add their byteswap macro in asm/byteorder.h
+ *    see how some architectures already do (i386, alpha, ppc, etc)
+ *   = cpu_to_beXX and beXX_to_cpu might some day need to be well
+ *    distinguished throughout the kernel. This is not the case currently,
+ *    since little endian, big endian, and pdp endian machines needn't it.

+	 * will know to send outbound memory downstream and everything else

+	 *
+	 * For example:
+	 *
+	 * - The best-case scenario, memory up to 3GB, is to place the inbound

+	 *   as well, since some devices require a 32bit MSI target address.
+	 *
+	 * - If the system memory is 4GB or larger we cannot start the inbound
+	 *   region at location 0 (since we have to allow some space for
+	 *   outbound memory @ 3GB). So instead it will  start at the 1x

-	 * The signal type is GPIO if the signal name has "GPIO" as a prefix.
-	 * strncmp (rather than strcmp) is used to implement the prefix
-	 * requirement.
+	 * We need to differentiate between GPIO and non-GPIO signals to
+	 * implement the gpio_request_enable() interface. For better or worse
+	 * the ASPEED pinctrl driver uses the expression names to determine
+	 * whether an expression will mux a pin for GPIO.
 	 *
-	 * expr->signal might look like "GPIOT3" in the GPIO case.
+	 * Generally we have the following - A GPIO such as B1 has:
+	 *
+	 *    - expr->signal set to "GPIOB1"
+	 *    - expr->function set to "GPIOB1"
+	 *
+	 * Using this fact we can determine whether the provided expression is
+	 * a GPIO expression by testing the signal name for the string prefix
+	 * "GPIO".
+	 *
+	 * However, some GPIOs are input-only, and the ASPEED datasheets name
+	 * them differently. An input-only GPIO such as T0 has:
+	 *
+	 *    - expr->signal set to "GPIT0"
+	 *    - expr->function set to "GPIT0"
+	 *
+	 * It's tempting to generalise the prefix test from "GPIO" to "GPI" to
+	 * account for both GPIOs and GPIs, but in doing so we run aground on
+	 * another feature:
+	 *
+	 * Some pins in the ASPEED BMC SoCs have a "pass-through" GPIO
+	 * function where the input state of one pin is replicated as the
+	 * output state of another (as if they were shorted together - a mux
+	 * configuration that is typically enabled by hardware strapping).
+	 * This feature allows the BMC to pass e.g. power button state through
+	 * to the host while the BMC is yet to boot, but take control of the
+	 * button state once the BMC has booted by muxing each pin as a
+	 * separate, pin-specific GPIO.
+	 *
+	 * Conceptually this pass-through mode is a form of GPIO and is named
+	 * as such in the datasheets, e.g. "GPID0". This naming similarity
+	 * trips us up with the simple GPI-prefixed-signal-name scheme
+	 * discussed above, as the pass-through configuration is not what we
+	 * want when muxing a pin as GPIO for the GPIO subsystem.
+	 *
+	 * On e.g. the AST2400, a pass-through function "GPID0" is grouped on
+	 * balls A18 and D16, where we have:
+	 *
+	 *    For ball A18:
+	 *    - expr->signal set to "GPID0IN"
+	 *    - expr->function set to "GPID0"
+	 *
+	 *    For ball D16:
+	 *    - expr->signal set to "GPID0OUT"
+	 *    - expr->function set to "GPID0"
+	 *
+	 * By contrast, the pin-specific GPIO expressions for the same pins are
+	 * as follows:
+	 *
+	 *    For ball A18:
+	 *    - expr->signal looks like "GPIOD0"
+	 *    - expr->function looks like "GPIOD0"
+	 *
+	 *    For ball D16:
+	 *    - expr->signal looks like "GPIOD1"
+	 *    - expr->function looks like "GPIOD1"
+	 *
+	 * Testing both the signal _and_ function names gives us the means
+	 * differentiate the pass-through GPIO pinmux configuration from the
+	 * pin-specific configuration that the GPIO subsystem is after: An
+	 * expression is a pin-specific (non-pass-through) GPIO configuration
+	 * if the signal prefix is "GPI" and the signal name matches the
+	 * function name.

+ * Cherry Trail SoC + AXP288 PMIC, Type-C,    DMI_BOARD_NAME: "813E"
+ * Cherry Trail SoC + TI PMIC,     Type-C,    DMI_BOARD_NAME: "827C" or "82F4"
+ *
+ * The variants with the AXP288 + Type-C connector are all kinds of special:
+ *
+ * 1. They use a Type-C connector which the AXP288 does not support, so when
+ * using a Type-C charger it is not recognized. Unlike most AXP288 devices,
+ * this model actually has mostly working ACPI AC / Battery code, the ACPI code
+ * "solves" this by simply setting the input_current_limit to 3A.
+ * There are still some issues with the ACPI code, so we use this native driver,
+ * and to solve the charging not working (500mA is not enough) issue we hardcode
+ * the 3A input_current_limit like the ACPI code does.
+ *
+ * 2. If no charger is connected the machine boots with the vbus-path disabled.
+ * Normally this is done when a 5V boost converter is active to avoid the PMIC
+ * trying to charge from the 5V boost converter's output. This is done when
+ * an OTG host cable is inserted and the ID pin on the micro-B receptacle is
+ * pulled low and the ID pin has an ACPI event handler associated with it
+ * which re-enables the vbus-path when the ID pin is pulled high when the
+ * OTG host cable is removed. The Type-C connector has no ID pin, there is
+ * no ID pin handler and there appears to be no 5V boost converter, so we
+ * end up not charging because the vbus-path is disabled, until we unplug
+ * the charger which automatically clears the vbus-path disable bit and then
+ * on the second plug-in of the adapter we start charging. To solve the not
+ * charging on first charger plugin we unconditionally enable the vbus-path at
+ * probe on this model, which is safe since there is no 5V boost converter.

+ * Description:
+ * This routine is the entry point for the debugfs open file operation. It gets

+ * for the log, fills the buffer from the in-memory log for this vport, and then

+ *
+ * Returns:
+ * This function returns zero if successful. On error it will return a negative

  * lpfc_sli4_enable_msix - Enable MSI-X interrupt mode to SLI-4 device

  *
  * This routine is invoked to enable the MSI-X interrupt vectors to device
- * with SLI-4 interface spec.
+ * with SLI-4 interface spec.  It also allocates MSI-X vectors and maps them
+ * to cpus on the system.
+ *
+ * When cfg_irq_numa is enabled, the adapter will only allocate vectors for
+ * the number of cpus on the same numa node as this adapter.  The vectors are
+ * allocated without requesting OS affinity mapping.  A vector will be
+ * allocated and assigned to each online and offline cpu.  If the cpu is
+ * online, then affinity will be set to that cpu.  If the cpu is offline, then
+ * affinity will be set to the nearest peer cpu within the numa node that is
+ * online.  If there are no online cpus within the numa node, affinity is not
+ * assigned and the OS may do as it pleases. Note: cpu vector affinity mapping
+ * is consistent with the way cpu online/offline is handled when cfg_irq_numa is
+ * configured.
+ *
+ * If numa mode is not enabled and there is more than 1 vector allocated, then
+ * the driver relies on the managed irq interface where the OS assigns vector to
+ * cpu affinity.  The driver will then use that affinity mapping to setup its
+ * cpu mapping table.
  *
  * Return codes

+1) Convert to be a platform driver.
+
+Right now when the module probes, it tries to initialize VCHI and
+errors out if it wasn't ready yet.  If bcm2835-v4l2 was built in, then
+VCHI generally isn't ready because it depends on both the firmware and
+mailbox drivers having already loaded.
+
+We should have VCHI create a platform device once it's initialized,
+and have this driver bind to it, so that we automatically load the
+v4l2 module after VCHI loads.
+
+2) Support SELECTION API to define crop region on the image for encode.
+
+Particularly for resolutions that aren't a multiple of the macroblock
+size, the codec will report a resolution that is a multiple of the macroblock
+size (it has to have the memory to decode into), and then a different crop
+region within that buffer.
+The most common example is 1080P, where the buffer will be 1920x1088 with a
+crop region of 1920x1080.
+
+3) Refactor so that the component creation is only on queue_setup, not open.
+
+Fixes v4l2-compliance failure on trying to open 100 instances of the
+device.

+ * Copyright: 2018, Raspberry Pi (Trading) Ltd
+ * Dave Stevenson <dave.stevenson@raspberrypi.org>
+ *
+ * Based on vmcs_sm driver from Broadcom Corporation for some API,
+ * and taking some code for buffer allocation and dmabuf handling from
+ * videobuf2.
+ *
+ *
+ * This driver has 3 main uses:
+ * 1) Allocating buffers for the kernel or userspace that can be shared with the
+ *    VPU.
+ * 2) Importing dmabufs from elsewhere for sharing with the VPU.
+ * 3) Allocating buffers for use by the VPU.
+ *
+ * In the first and second cases the native handle is a dmabuf. Releasing the
+ * resource inherently comes from releasing the dmabuf, and this will trigger
+ * unmapping on the VPU. The underlying allocation and our buffer structure are
+ * retained until the VPU has confirmed that it has finished with it.
+ *
+ * For the VPU allocations the VPU is responsible for triggering the release,
+ * and therefore the released message decrements the dma_buf refcount (with the
+ * VPU mapping having already been marked as released).

+ * The File-backed Storage Gadget acts as a USB Mass Storage device,
+ * appearing to the host as a disk drive or as a CD-ROM drive.  In addition
+ * to providing an example of a genuinely useful gadget driver for a USB
+ * device, it also illustrates a technique of double-buffering for increased
+ * throughput.  Last but not least, it gives an easy way to probe the
+ * behavior of the Mass Storage drivers in a USB host.
+ *
+ * Backing storage is provided by a regular file or a block device, specified
+ * by the "file" module parameter.  Access can be limited to read-only by
+ * setting the optional "ro" module parameter.  (For CD-ROM emulation,
+ * access is always read-only.)  The gadget will indicate that it has
+ * removable media if the optional "removable" module parameter is set.
+ *
+ * The gadget supports the Control-Bulk (CB), Control-Bulk-Interrupt (CBI),
+ * and Bulk-Only (also known as Bulk-Bulk-Bulk or BBB) transports, selected
+ * by the optional "transport" module parameter.  It also supports the
+ * following protocols: RBC (0x01), ATAPI or SFF-8020i (0x02), QIC-157 (0c03),
+ * UFI (0x04), SFF-8070i (0x05), and transparent SCSI (0x06), selected by
+ * the optional "protocol" module parameter.  In addition, the default
+ * Vendor ID, Product ID, release number and serial number can be overridden.
+ *
+ * There is support for multiple logical units (LUNs), each of which has
+ * its own backing file.  The number of LUNs can be set using the optional
+ * "luns" module parameter (anywhere from 1 to 8), and the corresponding
+ * files are specified using comma-separated lists for "file" and "ro".
+ * The default number of LUNs is taken from the number of "file" elements;
+ * it is 1 if "file" is not given.  If "removable" is not set then a backing
+ * file must be specified for each LUN.  If it is set, then an unspecified
+ * or empty backing filename means the LUN's medium is not loaded.  Ideally
+ * each LUN would be settable independently as a disk drive or a CD-ROM
+ * drive, but currently all LUNs have to be the same type.  The CD-ROM
+ * emulation includes a single data track and no audio tracks; hence there
+ * need be only one backing file per LUN.
+ *
+ * Requirements are modest; only a bulk-in and a bulk-out endpoint are
+ * needed (an interrupt-out endpoint is also needed for CBI).  The memory
+ * requirement amounts to two 16K buffers, size configurable by a parameter.
+ * Support is included for both full-speed and high-speed operation.
+ *
+ * Note that the driver is slightly non-portable in that it assumes a
+ * single memory/DMA buffer will be useable for bulk-in, bulk-out, and
+ * interrupt-in endpoints.  With most device controllers this isn't an
+ * issue, but there may be some with hardware restrictions that prevent
+ * a buffer from being used by more than one endpoint.
+ *
+ * Module options:
+ *
+ *	file=filename[,filename...]
+ *				Required if "removable" is not set, names of
+ *					the files or block devices used for
+ *					backing storage
+ *	serial=HHHH...		Required serial number (string of hex chars)
+ *	ro=b[,b...]		Default false, booleans for read-only access
+ *	removable		Default false, boolean for removable media
+ *	luns=N			Default N = number of filenames, number of
+ *					LUNs to support
+ *	nofua=b[,b...]		Default false, booleans for ignore FUA flag
+ *					in SCSI WRITE(10,12) commands
+ *	stall			Default determined according to the type of
+ *					USB device controller (usually true),
+ *					boolean to permit the driver to halt
+ *					bulk endpoints
+ *	cdrom			Default false, boolean for whether to emulate
+ *					a CD-ROM drive
+ *	transport=XXX		Default BBB, transport name (CB, CBI, or BBB)
+ *	protocol=YYY		Default SCSI, protocol name (RBC, 8020 or
+ *					ATAPI, QIC, UFI, 8070, or SCSI;
+ *					also 1 - 6)
+ *	vendor=0xVVVV		Default 0x0525 (NetChip), USB Vendor ID
+ *	product=0xPPPP		Default 0xa4a5 (FSG), USB Product ID
+ *	release=0xRRRR		Override the USB release number (bcdDevice)
+ *	buflen=N		Default N=16384, buffer size used (will be
+ *					rounded down to a multiple of
+ *					PAGE_CACHE_SIZE)
+ *
+ * If CONFIG_USB_FILE_STORAGE_TEST is not set, only the "file", "serial", "ro",
+ * "removable", "luns", "nofua", "stall", and "cdrom" options are available;
+ * default values are used for everything else.
+ *
+ * The pathnames of the backing files and the ro settings are available in
+ * the attribute files "file", "nofua", and "ro" in the lun<n> subdirectory of
+ * the gadget's sysfs directory.  If the "removable" option is set, writing to
+ * these files will simulate ejecting/loading the medium (writing an empty
+ * line means eject) and adjusting a write-enable tab.  Changes to the ro
+ * setting are not allowed when the medium is loaded or if CD-ROM emulation
+ * is being used.
+ *
+ * This gadget driver is heavily based on "Gadget Zero" by David Brownell.
+ * The driver's SCSI command interface was based on the "Information
+ * technology - Small Computer System Interface - 2" document from
+ * X3T9.2 Project 375D, Revision 10L, 7-SEP-93, available at
+ * <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>.  The single exception
+ * is opcode 0x23 (READ FORMAT CAPACITIES), which was based on the
+ * "Universal Serial Bus Mass Storage Class UFI Command Specification"
+ * document, Revision 1.0, December 14, 1998, available at
+ * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.

+
+
+/*
+ *				Driver Design
+ *
+ * The FSG driver is fairly straightforward.  There is a main kernel
+ * thread that handles most of the work.  Interrupt routines field
+ * callbacks from the controller driver: bulk- and interrupt-request
+ * completion notifications, endpoint-0 events, and disconnect events.
+ * Completion events are passed to the main thread by wakeup calls.  Many
+ * ep0 requests are handled at interrupt time, but SetInterface,
+ * SetConfiguration, and device reset requests are forwarded to the
+ * thread in the form of "exceptions" using SIGUSR1 signals (since they
+ * should interrupt any ongoing file I/O operations).
+ *
+ * The thread's main routine implements the standard command/data/status
+ * parts of a SCSI interaction.  It and its subroutines are full of tests
+ * for pending signals/exceptions -- all this polling is necessary since
+ * the kernel has no setjmp/longjmp equivalents.  (Maybe this is an
+ * indication that the driver really wants to be running in userspace.)
+ * An important point is that so long as the thread is alive it keeps an
+ * open reference to the backing file.  This will prevent unmounting
+ * the backing file's underlying filesystem and could cause problems
+ * during system shutdown, for example.  To prevent such problems, the
+ * thread catches INT, TERM, and KILL signals and converts them into
+ * an EXIT exception.
+ *
+ * In normal operation the main thread is started during the gadget's
+ * fsg_bind() callback and stopped during fsg_unbind().  But it can also
+ * exit when it receives a signal, and there's no point leaving the
+ * gadget running when the thread is dead.  So just before the thread
+ * exits, it deregisters the gadget driver.  This makes things a little
+ * tricky: The driver is deregistered at two places, and the exiting
+ * thread can indirectly call fsg_unbind() which in turn can tell the
+ * thread to exit.  The first problem is resolved through the use of the
+ * REGISTERED atomic bitflag; the driver will only be deregistered once.
+ * The second problem is resolved by having fsg_unbind() check
+ * fsg->state; it won't try to stop the thread if the state is already
+ * FSG_STATE_TERMINATED.
+ *
+ * To provide maximum throughput, the driver uses a circular pipeline of
+ * buffer heads (struct fsg_buffhd).  In principle the pipeline can be
+ * arbitrarily long; in practice the benefits don't justify having more
+ * than 2 stages (i.e., double buffering).  But it helps to think of the
+ * pipeline as being a long one.  Each buffer head contains a bulk-in and
+ * a bulk-out request pointer (since the buffer can be used for both
+ * output and input -- directions always are given from the host's
+ * point of view) as well as a pointer to the buffer and various state
+ * variables.
+ *
+ * Use of the pipeline follows a simple protocol.  There is a variable
+ * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
+ * At any time that buffer head may still be in use from an earlier
+ * request, so each buffer head has a state variable indicating whether
+ * it is EMPTY, FULL, or BUSY.  Typical use involves waiting for the
+ * buffer head to be EMPTY, filling the buffer either by file I/O or by
+ * USB I/O (during which the buffer head is BUSY), and marking the buffer
+ * head FULL when the I/O is complete.  Then the buffer will be emptied
+ * (again possibly by USB I/O, during which it is marked BUSY) and
+ * finally marked EMPTY again (possibly by a completion routine).
+ *
+ * A module parameter tells the driver to avoid stalling the bulk
+ * endpoints wherever the transport specification allows.  This is
+ * necessary for some UDCs like the SuperH, which cannot reliably clear a
+ * halt on a bulk endpoint.  However, under certain circumstances the
+ * Bulk-only specification requires a stall.  In such cases the driver
+ * will halt the endpoint and set a flag indicating that it should clear
+ * the halt in software during the next device reset.  Hopefully this
+ * will permit everything to work correctly.  Furthermore, although the
+ * specification allows the bulk-out endpoint to halt when the host sends
+ * too much data, implementing this would cause an unavoidable race.
+ * The driver will always use the "no-stall" approach for OUT transfers.
+ *
+ * One subtle point concerns sending status-stage responses for ep0
+ * requests.  Some of these requests, such as device reset, can involve
+ * interrupting an ongoing file I/O operation, which might take an
+ * arbitrarily long time.  During that delay the host might give up on
+ * the original ep0 request and issue a new one.  When that happens the
+ * driver should not notify the host about completion of the original
+ * request, as the host will no longer be waiting for it.  So the driver
+ * assigns to each ep0 request a unique tag, and it keeps track of the
+ * tag value of the request associated with a long-running exception
+ * (device-reset, interface-change, or configuration-change).  When the
+ * exception handler is finished, the status-stage response is submitted
+ * only if the current ep0 request tag is equal to the exception request
+ * tag.  Thus only the most recently received ep0 request will get a
+ * status-stage response.
+ *
+ * Warning: This driver source file is too long.  It ought to be split up
+ * into a header file plus about 3 separate .c files, to handle the details
+ * of the Gadget, USB Mass Storage, and SCSI protocols.

+
+dwc_read_reg32() and friends now take an additional parameter, a pointer to an
+IO context struct. The IO context struct should live in an os-dependent struct
+in your driver. As an example, the dwc_usb3 driver has an os-dependent struct
+named 'os_dep' embedded in the main device struct. So there these calls look
+like this:
+
+	dwc_read_reg32(&usb3_dev->os_dep.ioctx, &pcd->dev_global_regs->dcfg);
+
+	dwc_write_reg32(&usb3_dev->os_dep.ioctx,
+			&pcd->dev_global_regs->dcfg, 0);
+
+Note that for the existing Linux driver ports, it is not necessary to actually
+define the 'ioctx' member in the os-dependent struct. Since Linux does not
+require an IO context, its macros for dwc_read_reg32() and friends do not
+use the context pointer, so it is optimized away by the compiler. But it is
+necessary to add the pointer parameter to all of the call sites, to be ready
+for any future ports (such as FreeBSD) which do require an IO context.
+
+
+Similarly, dwc_alloc(), dwc_alloc_atomic(), dwc_strdup(), and dwc_free() now
+take an additional parameter, a pointer to a memory context. Examples:
+
+	addr = dwc_alloc(&usb3_dev->os_dep.memctx, size);
+
+	dwc_free(&usb3_dev->os_dep.memctx, addr);
+
+Again, for the Linux ports, it is not necessary to actually define the memctx
+member, but it is necessary to add the pointer parameter to all of the call
+sites.
+
+
+Same for dwc_dma_alloc() and dwc_dma_free(). Examples:
+
+	virt_addr = dwc_dma_alloc(&usb3_dev->os_dep.dmactx, size, &phys_addr);
+
+	dwc_dma_free(&usb3_dev->os_dep.dmactx, size, virt_addr, phys_addr);
+
+
+Same for dwc_mutex_alloc() and dwc_mutex_free(). Examples:
+
+	mutex = dwc_mutex_alloc(&usb3_dev->os_dep.mtxctx);
+
+	dwc_mutex_free(&usb3_dev->os_dep.mtxctx, mutex);
+
+
+Same for dwc_spinlock_alloc() and dwc_spinlock_free(). Examples:
+
+	lock = dwc_spinlock_alloc(&usb3_dev->osdep.splctx);
+
+	dwc_spinlock_free(&usb3_dev->osdep.splctx, lock);
+
+
+Same for dwc_timer_alloc(). Example:
+
+	timer = dwc_timer_alloc(&usb3_dev->os_dep.tmrctx, "dwc_usb3_tmr1",
+				cb_func, cb_data);
+
+
+Same for dwc_waitq_alloc(). Example:
+
+	waitq = dwc_waitq_alloc(&usb3_dev->os_dep.wtqctx);
+
+
+Same for dwc_thread_run(). Example:
+
+	thread = dwc_thread_run(&usb3_dev->os_dep.thdctx, func,
+				"dwc_usb3_thd1", data);
+
+
+Same for dwc_workq_alloc(). Example:
+
+	workq = dwc_workq_alloc(&usb3_dev->osdep.wkqctx, "dwc_usb3_wkq1");
+
+
+Same for dwc_task_alloc(). Example:
+
+	task = dwc_task_alloc(&usb3_dev->os_dep.tskctx, "dwc_usb3_tsk1",
+			      cb_func, cb_data);
+
+
+In addition to the context pointer additions, a few core functions have had
+other changes made to their parameters:
+
+The 'flags' parameter to dwc_spinlock_irqsave() and dwc_spinunlock_irqrestore()
+has been changed from a uint64_t to a dwc_irqflags_t.
+
+dwc_thread_should_stop() now takes a 'dwc_thread_t *' parameter, because the
+FreeBSD equivalent of that function requires it.
+
+And, in addition to the context pointer, dwc_task_alloc() also adds a
+'char *name' parameter, to be consistent with dwc_thread_run() and
+dwc_workq_alloc(), and because the FreeBSD equivalent of that function
+requires a unique name.
+
+
+Here is a complete list of the core functions that now take a pointer to a
+context as their first parameter:
+
+	dwc_read_reg32
+	dwc_read_reg64
+	dwc_write_reg32
+	dwc_write_reg64
+	dwc_modify_reg32
+	dwc_modify_reg64
+	dwc_alloc
+	dwc_alloc_atomic
+	dwc_strdup
+	dwc_free
+	dwc_dma_alloc
+	dwc_dma_free
+	dwc_mutex_alloc
+	dwc_mutex_free
+	dwc_spinlock_alloc
+	dwc_spinlock_free
+	dwc_timer_alloc
+	dwc_waitq_alloc
+	dwc_thread_run
+	dwc_workq_alloc
+	dwc_task_alloc     Also adds a 'char *name' as its 2nd parameter
+
+And here are the core functions that have other changes to their parameters:
+
+	dwc_spinlock_irqsave      'flags' param is now a 'dwc_irqflags_t *'
+	dwc_spinunlock_irqrestore 'flags' param is now a 'dwc_irqflags_t'
+	dwc_thread_should_stop    Adds a 'dwc_thread_t *' parameter
+
+
+
+The changes to the core functions also require some of the other library
+functions to change:
+
+	dwc_cc_if_alloc() and dwc_cc_if_free() now take a 'void *memctx'
+	(for memory allocation) as the 1st param and a 'void *mtxctx'
+	(for mutex allocation) as the 2nd param.
+
+	dwc_cc_clear(), dwc_cc_add(), dwc_cc_change(), dwc_cc_remove(),
+	dwc_cc_data_for_save(), and dwc_cc_restore_from_data() now take a
+	'void *memctx' as the 1st param.
+
+	dwc_dh_modpow(), dwc_dh_pk(), and dwc_dh_derive_keys() now take a
+	'void *memctx' as the 1st param.
+
+	dwc_modpow() now takes a 'void *memctx' as the 1st param.
+
+	dwc_alloc_notification_manager() now takes a 'void *memctx' as the
+	1st param and a 'void *wkqctx' (for work queue allocation) as the 2nd
+	param, and also now returns an integer value that is non-zero if
+	allocation of its data structures or work queue fails.
+
+	dwc_register_notifier() now takes a 'void *memctx' as the 1st param.
+
+	dwc_memory_debug_start() now takes a 'void *mem_ctx' as the first
+	param, and also now returns an integer value that is non-zero if
+	allocation of its data structures fails.
+
+
+
+Other miscellaneous changes:
+
+The DEBUG_MEMORY and DEBUG_REGS #define's have been renamed to
+DWC_DEBUG_MEMORY and DWC_DEBUG_REGS.
+
+The following #define's have been added to allow selectively compiling library
+features:
+
+	DWC_CCLIB
+	DWC_CRYPTOLIB
+	DWC_NOTIFYLIB
+	DWC_UTFLIB
+
+A DWC_LIBMODULE #define has also been added. If this is not defined, then the
+module code in dwc_common_linux.c is not compiled in. This allows linking the
+library code directly into a driver module, instead of as a standalone module.

+
+/*
+ * This file defines five types of data structures: singly-linked lists,
+ * lists, simple queues, tail queues, and circular queues.
+ *
+ *
+ * A singly-linked list is headed by a single forward pointer. The elements
+ * are singly linked for minimum space and pointer manipulation overhead at
+ * the expense of O(n) removal for arbitrary elements. New elements can be
+ * added to the list after an existing element or at the head of the list.
+ * Elements being removed from the head of the list should use the explicit
+ * macro for this purpose for optimum efficiency. A singly-linked list may
+ * only be traversed in the forward direction.  Singly-linked lists are ideal
+ * for applications with large datasets and few or no removals or for
+ * implementing a LIFO queue.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may only be traversed in the forward direction.
+ *
+ * A simple queue is headed by a pair of pointers, one the head of the
+ * list and the other to the tail of the list. The elements are singly
+ * linked to save space, so elements can only be removed from the
+ * head of the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the
+ * list. A simple queue may only be traversed in the forward direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may be traversed in either direction.
+ *
+ * A circle queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the list.
+ * A circle queue may be traversed in either direction, but has a more
+ * complex end of list detection.
+ *
+ * For details on the use of these macros, see the queue(3) manual page.

+/** @file
+ *
+ * A simple implementation of the Observer pattern.  Any "module" can
+ * register as an observer or notifier.  The notion of "module" is abstract and
+ * can mean anything used to identify either an observer or notifier.  Usually
+ * it will be a pointer to a data structure which contains some state, ie an
+ * object.
+ *
+ * Before any notifiers can be added, the global notification manager must be
+ * brought up with dwc_alloc_notification_manager().
+ * dwc_free_notification_manager() will bring it down and free all resources.
+ * These would typically be called upon module load and unload.  The
+ * notification manager is a single global instance that handles all registered
+ * observable modules and observers so this should be done only once.
+ *
+ * A module can be observable by using Notifications to publicize some general
+ * information about it's state or operation.  It does not care who listens, or
+ * even if anyone listens, or what they do with the information.  The observable
+ * modules do not need to know any information about it's observers or their
+ * interface, or their state or data.
+ *
+ * Any module can register to emit Notifications.  It should publish a list of
+ * notifications that it can emit and their behavior, such as when they will get
+ * triggered, and what information will be provided to the observer.  Then it
+ * should register itself as an observable module. See dwc_register_notifier().
+ *
+ * Any module can observe any observable, registered module, provided it has a
+ * handle to the other module and knows what notifications to observe.  See
+ * dwc_add_observer().
+ *
+ * A function of type dwc_notifier_callback_t is called whenever a notification
+ * is triggered with one or more observers observing it.  This function is
+ * called in it's own process so it may sleep or block if needed.  It is
+ * guaranteed to be called sometime after the notification has occurred and will
+ * be called once per each time the notification is triggered.  It will NOT be
+ * called in the same process context used to trigger the notification.
+ *
+ * @section Limitiations
+ *
+ * Keep in mind that Notifications that can be triggered in rapid sucession may
+ * schedule too many processes too handle.  Be aware of this limitation when
+ * designing to use notifications, and only add notifications for appropriate
+ * observable information.
+ *
+ * Also Notification callbacks are not synchronous.  If you need to synchronize
+ * the behavior between module/observer you must use other means.  And perhaps
+ * that will mean Notifications are not the proper solution.

+/* @mainpage DWC Portability and Common Library
+ *
+ * This is the documentation for the DWC Portability and Common Library.
+ *
+ * @section intro Introduction
+ *
+ * The DWC Portability library consists of wrapper calls and data structures to
+ * all low-level functions which are typically provided by the OS.  The WUDEV
+ * driver uses only these functions.  In order to port the WUDEV driver, only
+ * the functions in this library need to be re-implemented, with the same
+ * behavior as documented here.
+ *
+ * The Common library consists of higher level functions, which rely only on
+ * calling the functions from the DWC Portability library.  These common
+ * routines are shared across modules.  Some of the common libraries need to be
+ * used directly by the driver programmer when porting WUDEV.  Such as the
+ * parameter and notification libraries.
+ *
+ * @section low Portability Library OS Wrapper Functions
+ *
+ * Any function starting with DWC and in all CAPS is a low-level OS-wrapper that
+ * needs to be implemented when porting, for example DWC_MUTEX_ALLOC().  All of
+ * these functions are included in the dwc_os.h file.
+ *
+ * There are many functions here covering a wide array of OS services.  Please
+ * see dwc_os.h for details, and implementation notes for each function.
+ *
+ * @section common Common Library Functions
+ *
+ * Any function starting with dwc and in all lowercase is a common library
+ * routine.  These functions have a portable implementation and do not need to
+ * be reimplemented when porting.  The common routines can be used by any
+ * driver, and some must be used by the end user to control the drivers.  For
+ * example, you must use the Parameter common library in order to set the
+ * parameters in the WUDEV module.
+ *
+ * The common libraries consist of the following:
+ *
+ * - Connection Contexts - Used internally and can be used by end-user.  See dwc_cc.h
+ * - Parameters - Used internally and can be used by end-user.  See dwc_params.h
+ * - Notifications - Used internally and can be used by end-user.  See dwc_notifier.h
+ * - Lists - Used internally and can be used by end-user.  See dwc_list.h
+ * - Memory Debugging - Used internally and can be used by end-user.  See dwc_os.h
+ * - Modpow - Used internally only.  See dwc_modpow.h
+ * - DH - Used internally only.  See dwc_dh.h
+ * - Crypto - Used internally only.  See dwc_crypto.h
+ *
+ *
+ * @section prereq Prerequistes For dwc_os.h
+ * @subsection types Data Types
+ *
+ * The dwc_os.h file assumes that several low-level data types are pre defined for the
+ * compilation environment.  These data types are:
+ *
+ * - uint8_t - unsigned 8-bit data type
+ * - int8_t - signed 8-bit data type
+ * - uint16_t - unsigned 16-bit data type
+ * - int16_t - signed 16-bit data type
+ * - uint32_t - unsigned 32-bit data type
+ * - int32_t - signed 32-bit data type
+ * - uint64_t - unsigned 64-bit data type
+ * - int64_t - signed 64-bit data type
+ *
+ * Ensure that these are defined before using dwc_os.h.  The easiest way to do
+ * that is to modify the top of the file to include the appropriate header.
+ * This is already done for the Linux environment.  If the DWC_LINUX macro is
+ * defined, the correct header will be added.  A standard header <stdint.h> is
+ * also used for environments where standard C headers are available.
+ *
+ * @subsection stdarg Variable Arguments
+ *
+ * Variable arguments are provided by a standard C header <stdarg.h>.  it is
+ * available in Both the Linux and ANSI C enviornment.  An equivalent must be
+ * provided in your enviornment in order to use dwc_os.h with the debug and
+ * tracing message functionality.
+ *
+ * @subsection thread Threading
+ *
+ * WUDEV Core must be run on an operating system that provides for multiple
+ * threads/processes.  Threading can be implemented in many ways, even in
+ * embedded systems without an operating system.  At the bare minimum, the
+ * system should be able to start any number of processes at any time to handle
+ * special work.  It need not be a pre-emptive system.  Process context can
+ * change upon a call to a blocking function.  The hardware interrupt context
+ * that calls the module's ISR() function must be differentiable from process
+ * context, even if your processes are impemented via a hardware interrupt.
+ * Further locking mechanism between process must exist (or be implemented), and
+ * process context must have a way to disable interrupts for a period of time to
+ * lock them out.  If all of this exists, the functions in dwc_os.h related to
+ * threading should be able to be implemented with the defined behavior.
+ *

+ *
+ * Hardware details are visible (see CONFIG_USB_ZERO_* below) but don't
+ * affect most of the driver.
+ *
+ * Use it with the Linux host/master side "usbtest" driver to get a basic
+ * functional test of your device-side usb stack, or with "usb-skeleton".
+ *
+ * It supports two similar configurations.  One sinks whatever the usb host
+ * writes, and in return sources zeroes.  The other loops whatever the host
+ * writes back, so the host can read it.  Module options include:
+ *
+ *   buflen=N		default N=4096, buffer size used
+ *   qlen=N		default N=32, how many buffers in the loopback queue
+ *   loopdefault	default false, list loopback config first
+ *
+ * Many drivers will only have one configuration, letting them be much
+ * simpler if they also don't support high speed operation (like this
+ * driver does).

+/** @file
+ *
+ * The Core Interface Layer provides basic services for accessing and
+ * managing the DWC_otg hardware. These services are used by both the
+ * Host Controller Driver and the Peripheral Controller Driver.
+ *
+ * The CIL manages the memory map for the core so that the HCD and PCD
+ * don't have to do this separately. It also handles basic tasks like
+ * reading/writing the registers and data FIFOs in the controller.
+ * Some of the data access functions provide encapsulation of several
+ * operations required to perform a task, such as writing multiple
+ * registers to start a transfer. Finally, the CIL performs basic
+ * services that are not specific to either the host or device modes
+ * of operation. These services include management of the OTG Host
+ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
+ * Diagnostic API is also provided to allow testing of the controller
+ * hardware.
+ *
+ * The Core Interface Layer has the following requirements:
+ * - Provides basic controller operations.
+ * - Minimal use of OS services.
+ * - The OS services used will be abstracted by using inline functions
+ *	 or macros.

+ * This FIQ implements functionality that performs split transactions on
+ * the dwc_otg hardware without any outside intervention. A split transaction
+ * is "queued" by nominating a specific host channel to perform the entirety
+ * of a split transaction. This FIQ will then perform the microframe-precise
+ * scheduling required in each phase of the transaction until completion.
+ *
+ * The FIQ functionality is glued into the Synopsys driver via the entry point
+ * in the FSM enqueue function, and at the exit point in handling a HC interrupt
+ * for a FSM-enabled channel.
+ *
+ * NB: Large parts of this implementation have architecture-specific code.
+ * For porting this functionality to other ARM machines, the minimum is required:
+ * - An interrupt controller allowing the top-level dwc USB interrupt to be routed
+ *   to the FIQ
+ * - A method of forcing a software generated interrupt from FIQ mode that then
+ *   triggers an IRQ entry (with the dwc USB handler called by this IRQ number)
+ * - Guaranteed interrupt routing such that both the FIQ and SGI occur on the same
+ *   processor core - there is no locking between the FIQ and IRQ (aside from
+ *   local_fiq_disable)

+ * This file contains the data structures for accessing the DWC_otg core registers.
+ *
+ * The application interfaces with the HS OTG core by reading from and
+ * writing to the Control and Status Register (CSR) space through the
+ * AHB Slave interface. These registers are 32 bits wide, and the
+ * addresses are 32-bit-block aligned.
+ * CSRs are classified as follows:
+ * - Core Global Registers
+ * - Device Mode Registers
+ * - Device Global Registers
+ * - Device Endpoint Specific Registers
+ * - Host Mode Registers
+ * - Host Global Registers
+ * - Host Port CSRs
+ * - Host Channel Specific Registers
+ *
+ * Only the Core Global registers can be accessed in both Device and
+ * Host modes. When the HS OTG core is operating in one mode, either
+ * Device or Host, the application must not access registers from the
+ * other mode. When the core switches from one mode to another, the
+ * registers in the new mode of operation must be reprogrammed as they

+	 * The memory_lock semaphore is used by both code paths calling
+	 * into this function to zap vmas and the vm_ops.fault callback
+	 * to protect the memory enable state of the device.
+	 *
+	 * When zapping vmas we need to maintain the mmap_sem => vma_lock
+	 * ordering, which requires using vma_lock to walk vma_list to
+	 * acquire an mm, then dropping vma_lock to get the mmap_sem and
+	 * reacquiring vma_lock.  This logic is derived from similar
+	 * requirements in uverbs_user_mmap_disassociate().
+	 *
+	 * mmap_sem must always be the top-level lock when it is taken.
+	 * Therefore we can only hold the memory_lock write lock when
+	 * vma_list is empty, as we'd need to take mmap_sem to clear
+	 * entries.  vma_list can only be guaranteed empty when holding
+	 * vma_lock, thus memory_lock is nested under vma_lock.
+	 *
+	 * This enables the vm_ops.fault callback to acquire vma_lock,

-	 the VGA RAM.  The size of this RAM is fixed and is quite small.
-	 If you require a larger scrollback buffer, this can be placed in
-	 System RAM which is dynamically allocated during initialization.
-	 Placing the scrollback buffer in System RAM will slightly slow
-	 down the console.

-	  flushed each time the console is switched. This feature can also be
-	  enabled using the boot command line parameter
-	  'vgacon.scrollback_persistent=1'.
-
-	  This feature might break your tool of choice to flush the scrollback
-	  buffer, e.g. clear(1) will work fine but Debian's clear_console(1)
-	  will be broken, which might cause security issues.
-	  You can use the escape sequence \e[3J instead if this feature is
-	  activated.
-
-	  Note that a buffer of VGACON_SOFT_SCROLLBACK_SIZE is taken for each
-	  created tty device.

+	help
+	Aufs has two methods to provide a merged view for a directory,

+	is always enabled but sometimes large and slow.
+	If you enable this option, install the library in aufs2-util
+	package, and set some environment variables for your readdir(3),
+	then the work will be handled in user-space which generally
+	shows better performance in most cases.
+	See detail in aufs.5.
+
+config AUFS_DIRREN
+	bool "Workaround for rename(2)-ing a directory"
+	help
+	By default, aufs returns EXDEV error in renameing a dir who has

+	rename(2) internally for every lower branch. But user may not
+	accept this behaviour. So here is a workaround to allow such
+	rename(2) and store some extra infromation on the writable
+	branch. Obviously this costs high (and I don't like it).
+	To use this feature, you need to enable this configuration AND
+	to specify the mount option `dirren.'
+	See details in aufs.5 and the design documents.

+	help
+	If you want to make the whiteouts in aufs visible, then enable

+	help
+	If you want to use ramfs as an aufs branch fs, then enable this

+	Aufs prohibited them to be a branch fs by default, because
+	initramfs becomes unusable after switch_root or something
+	generally. If you sets initramfs as an aufs branch and boot your
+	system by switch_root, you will meet a problem easily since the
+	files in initramfs may be inaccessible.
+	Unless you are going to use ramfs as an aufs branch fs without
+	switch_root or something, leave it N.

+ * When processing the new references for an inode we may orphanize an existing

+ * inode, we might need to orphanize another inode, but the path we have in the
+ * reference reflects the pre-orphanization name of the directory we previously
+ * orphanized. For example:
+ *
+ * parent snapshot looks like:
+ *
+ * .                                     (ino 256)

+ *        |----- d2/                     (ino 260)

+ * |----- f2/                            (ino 259)

+ * When processing inode 257 we compute the name for inode 259 as "d1", and we
+ * cache it in the name cache. Later when we start processing inode 258, when
+ * collecting all its new references we set a full path of "d1/d2" for its new
+ * reference with name "d2". When we start processing the new references we
+ * start by processing the new reference with name "d1", and this results in
+ * orphanizing inode 259, since its old reference causes a conflict. Then we
+ * move on the next new reference, with name "d2", and we find out we must
+ * orphanize inode 260, as its old reference conflicts with ours - but for the
+ * orphanization we use a source path corresponding to the path we stored in the
+ * new reference, which is "d1/d2" and not "o259-6-0/d2" - this makes the
+ * receiver fail since the path component "d1/" no longer exists, it was renamed
+ * to "o259-6-0/" when processing the previous new reference. So in this case we
+ * must recompute the path in the new reference and use it for the new

- * transaction commits.  A separate, higher bound defines when CIL pushes are
- * enforced to ensure we stay within our maximum checkpoint size bounds.
- * threshold, yet give us plenty of space for aggregation on large logs.
+ * In order to keep background CIL push efficient, we only need to ensure the
+ * CIL is large enough to maintain sufficient in-memory relogging to avoid
+ * repeated physical writes of frequently modified metadata. If we allow the CIL
+ * to grow to a substantial fraction of the log, then we may be pinning hundreds
+ * of megabytes of metadata in memory until the CIL flushes. This can cause
+ * issues when we are running low on memory - pinned memory cannot be reclaimed,
+ * and the CIL consumes a lot of memory. Hence we need to set an upper physical
+ * size limit for the CIL that limits the maximum amount of memory pinned by the
+ * CIL but does not limit performance by reducing relogging efficiency
+ * significantly.
+ *
+ * As such, the CIL push threshold ends up being the smaller of two thresholds:
+ * - a threshold large enough that it allows CIL to be pushed and progress to be
+ *   made without excessive blocking of incoming transaction commits. This is
+ *   defined to be 12.5% of the log space - half the 25% push threshold of the
+ *   AIL.
+ * - small enough that it doesn't pin excessive amounts of memory but maintains
+ *   close to peak relogging efficiency. This is defined to be 16x the iclog
+ *   buffer window (32MB) as measurements have shown this to be roughly the
+ *   point of diminishing performance increases under highly concurrent
+ *   modification workloads.
+ *
+ * To prevent the CIL from overflowing upper commit size bounds, we introduce a
+ * new threshold at which we block committing transactions until the background
+ * CIL commit commences and switches to a new context. While this is not a hard
+ * limit, it forces the process committing a transaction to the CIL to block and
+ * yeild the CPU, giving the CIL push work a chance to be scheduled and start
+ * work. This prevents a process running lots of transactions from overfilling
+ * the CIL because it is not yielding the CPU. We set the blocking limit at
+ * twice the background push space threshold so we keep in line with the AIL
+ * push thresholds.
+ *
+ * Note: this is not a -hard- limit as blocking is applied after the transaction
+ * is inserted into the CIL and the push has been triggered. It is largely a
+ * throttling mechanism that allows the CIL push to be scheduled and run. A hard
+ * limit will be difficult to implement without introducing global serialisation
+ * in the CIL commit fast path, and it's not at all clear that we actually need
+ * such hard limits given the ~7 years we've run without a hard limit before
+ * finding the first situation where a checkpoint size overflow actually
+ * occurred. Hence the simple throttle, and an ASSERT check to tell us that
+ * we've overrun the max size.

+ * Variant of atomic_t specialized for reference counts.
+ *
+ * The interface matches the atomic_t interface (to aid in porting) but only
+ * provides the few functions one should use for reference counting.
+ *
+ * Saturation semantics
+ * ====================
+ *
+ * refcount_t differs from atomic_t in that the counter saturates at
+ * REFCOUNT_SATURATED and will not move once there. This avoids wrapping the
+ * counter and causing 'spurious' use-after-free issues. In order to avoid the
+ * cost associated with introducing cmpxchg() loops into all of the saturating
+ * operations, we temporarily allow the counter to take on an unchecked value
+ * and then explicitly set it to REFCOUNT_SATURATED on detecting that underflow
+ * or overflow has occurred. Although this is racy when multiple threads
+ * access the refcount concurrently, by placing REFCOUNT_SATURATED roughly
+ * equidistant from 0 and INT_MAX we minimise the scope for error:
+ *
+ * 	                           INT_MAX     REFCOUNT_SATURATED   UINT_MAX
+ *   0                          (0x7fff_ffff)    (0xc000_0000)    (0xffff_ffff)
+ *   +--------------------------------+----------------+----------------+
+ *                                     <---------- bad value! ---------->
+ *
+ * (in a signed view of the world, the "bad value" range corresponds to
+ * a negative counter value).
+ *
+ * As an example, consider a refcount_inc() operation that causes the counter
+ * to overflow:
+ *
+ * 	int old = atomic_fetch_add_relaxed(r);
+ *	// old is INT_MAX, refcount now INT_MIN (0x8000_0000)
+ *	if (old < 0)
+ *		atomic_set(r, REFCOUNT_SATURATED);
+ *
+ * If another thread also performs a refcount_inc() operation between the two
+ * atomic operations, then the count will continue to edge closer to 0. If it
+ * reaches a value of 1 before /any/ of the threads reset it to the saturated
+ * value, then a concurrent refcount_dec_and_test() may erroneously free the
+ * underlying object. Given the precise timing details involved with the
+ * round-robin scheduling of each thread manipulating the refcount and the need
+ * to hit the race multiple times in succession, there doesn't appear to be a
+ * practical avenue of attack even if using refcount_add() operations with
+ * larger increments.
+ *
+ * Memory ordering
+ * ===============
+ *
+ * Memory ordering rules are slightly relaxed wrt regular atomic_t functions
+ * and provide only what is strictly required for refcounts.
+ *
+ * The increments are fully relaxed; these will not provide ordering. The
+ * rationale is that whatever is used to obtain the object we're increasing the
+ * reference count on will provide the ordering. For locked data structures,
+ * its the lock acquire, for RCU/lockless data structures its the dependent
+ * load.
+ *
+ * Do note that inc_not_zero() provides a control dependency which will order
+ * future stores against the inc, this ensures we'll never modify the object
+ * if we did not in fact acquire a reference.
+ *
+ * The decrements will provide release order, such that all the prior loads and
+ * stores will be issued before, it also provides a control dependency, which
+ * will order us against the subsequent free().
+ *
+ * The control dependency is against the load of the cmpxchg (ll/sc) that
+ * succeeded. This means the stores aren't fully ordered, but this is fine
+ * because the 1->0 transition indicates no concurrency.
+ *
+ * Note that the allocator is responsible for ordering things between free()
+ * and alloc().
+ *
+ * The decrements dec_and_test() and sub_and_test() also provide acquire
+ * ordering on success.

+ * another security mechanism or the kernel itself will sufficiently block
+ * syscalls if arguments are rewritten to something unsafe.
+ *
+ * Similar precautions should be applied when stacking SECCOMP_RET_USER_NOTIF
+ * or SECCOMP_RET_TRACE. For SECCOMP_RET_USER_NOTIF filters acting on the

+ * that the new SECCOMP_RET_USER_NOTIF filter can override any
+ * SECCOMP_IOCTL_NOTIF_SEND from earlier filters, essentially allowing all

  * Macros to make the correct C datatypes for a new kind of ring.
  *
  * To make a new ring datatype, you need to have two message structures,
- * let's say struct request, and struct response already defined.
+ * let's say request_t, and response_t already defined.
  *
  * In a header where you want the ring datatype declared, you then do:
  *
- *     DEFINE_RING_TYPES(mytag, struct request, struct response);
+ *     DEFINE_RING_TYPES(mytag, request_t, response_t);
  *
  * These expand out to give you a set of types, as you can see below.
  * The most important of these are:
  *
- *     struct mytag_sring      - The shared ring.
- *     struct mytag_front_ring - The 'front' half of the ring.
- *     struct mytag_back_ring  - The 'back' half of the ring.
+ *     mytag_sring_t      - The shared ring.
+ *     mytag_front_ring_t - The 'front' half of the ring.
+ *     mytag_back_ring_t  - The 'back' half of the ring.
  *
  * To initialize a ring in your code you need to know the location and size
  * of the shared memory area (PAGE_SIZE, for instance). To initialise
  * the front half:
  *
- *     struct mytag_front_ring front_ring;
- *     SHARED_RING_INIT((struct mytag_sring *)shared_page);
- *     FRONT_RING_INIT(&front_ring, (struct mytag_sring *)shared_page,
- *		       PAGE_SIZE);
+ *     mytag_front_ring_t front_ring;
+ *     SHARED_RING_INIT((mytag_sring_t *)shared_page);
+ *     FRONT_RING_INIT(&front_ring, (mytag_sring_t *)shared_page, PAGE_SIZE);
  *
  * Initializing the back follows similarly (note that only the front
  * initializes the shared ring):
  *
- *     struct mytag_back_ring back_ring;
- *     BACK_RING_INIT(&back_ring, (struct mytag_sring *)shared_page,
- *		      PAGE_SIZE);
+ *     mytag_back_ring_t back_ring;
+ *     BACK_RING_INIT(&back_ring, (mytag_sring_t *)shared_page, PAGE_SIZE);

 /*
- * printk the shortest lock dependencies from @start to @end in reverse order:
+ * Dependency path printing:
+ *
+ * After BFS we get a lock dependency path (linked via ->parent of lock_list),
+ * printing out each lock in the dependency path will help on understanding how
+ * the deadlock could happen. Here are some details about dependency path
+ * printing:
+ *
+ * 1)	A lock_list can be either forwards or backwards for a lock dependency,
+ * 	for a lock dependency A -> B, there are two lock_lists:
+ *
+ * 	a)	lock_list in the ->locks_after list of A, whose ->class is B and
+ * 		->links_to is A. In this case, we can say the lock_list is
+ * 		"A -> B" (forwards case).
+ *
+ * 	b)	lock_list in the ->locks_before list of B, whose ->class is A
+ * 		and ->links_to is B. In this case, we can say the lock_list is
+ * 		"B <- A" (bacwards case).
+ *
+ * 	The ->trace of both a) and b) point to the call trace where B was
+ * 	acquired with A held.
+ *
+ * 2)	A "helper" lock_list is introduced during BFS, this lock_list doesn't
+ * 	represent a certain lock dependency, it only provides an initial entry
+ * 	for BFS. For example, BFS may introduce a "helper" lock_list whose
+ * 	->class is A, as a result BFS will search all dependencies starting with
+ * 	A, e.g. A -> B or A -> C.
+ *
+ * 	The notation of a forwards helper lock_list is like "-> A", which means
+ * 	we should search the forwards dependencies starting with "A", e.g A -> B
+ * 	or A -> C.
+ *
+ * 	The notation of a bacwards helper lock_list is like "<- B", which means
+ * 	we should search the backwards dependencies ending with "B", e.g.
+ * 	B <- A or B <- C.

- *
- * This function only differs from del_timer() on SMP: besides deactivating
- * the timer it also makes sure the handler has finished executing on other
- * CPUs.
- *
- * Synchronization rules: Callers must prevent restarting of the timer,
- * otherwise this function is meaningless. It must not be called from
- * interrupt contexts unless the timer is an irqsafe one. The caller must
- * not hold locks which would prevent completion of the timer's
- * handler. The timer's handler must not call add_timer_on(). Upon exit the
- * timer is not queued and the handler is not running on any CPU.
- *
- * Note: For !irqsafe timers, you must not hold locks that are held in
- *   interrupt context while calling this function. Even if the lock has
- *   nothing to do with the timer in question.  Here's why::

- *    while (base->running_timer == mytimer);
- *
- * Now del_timer_sync() will never return and never release somelock.
- * The interrupt on the other CPU is waiting to grab somelock but
- * it has interrupted the softirq that CPU0 is waiting to finish.

+ *
+ * Given a /8 overlay and /16 underlay, for an overlay (inner) address
+ * Y.A.B.C, the transformation is F.G.A.B, where "F" and "G" are the first
+ * two octets of the underlay network (the network portion of a /16), "A"
+ * and "B" are the low order two octets of the underlay network host (the
+ * host portion of a /16), and "Y" is a configured first octet of the
+ * overlay network.
+ *
+ * E.g., underlay host 10.88.3.4/16 with an overlay of 99.0.0.0/8 would
+ * host overlay subnet 99.3.4.0/24.  An overlay network datagram from
+ * 99.3.4.5 to 99.6.7.8, would be directed to underlay host 10.88.6.7,
+ * which hosts overlay network subnet 99.6.7.0/24.  This transformation is
+ * described in detail further below.
+ *
+ * Using netmasks for the overlay and underlay other than /8 and /16, as
+ * shown above, can yield larger (or smaller) overlay subnets, with the
+ * trade-off of allowing fewer (or more) underlay hosts to participate.
+ *
+ * The size of each overlay network subnet is defined by the total of the
+ * network mask of the overlay plus the size of host portion of the
+ * underlay network. In the above example, /8 + /16 = /24.
+ *
+ * E.g., consider underlay host 10.99.238.5/20 and overlay 99.0.0.0/8. In
+ * this case, the network portion of the underlay is 10.99.224.0/20, and
+ * the host portion is 0.0.14.5 (12 bits).  To determine the overlay
+ * network subnet, the 12 bits of host portion are left shifted 12 bits
+ * (/20 - /8) and ORed with the overlay subnet prefix.  This yields an
+ * overlay subnet of 99.224.80/20, composed of 8 bits overlay, followed by
+ * 12 bits underlay.  This yields 12 bits in the overlay network portion,
+ * allowing for 4094 addresses in each overlay network subnet.  The
+ * trade-off is that fewer hosts may participate in the underlay network,
+ * as its host address size has shrunk from 16 bits (65534 addresses) in
+ * the first example to 12 bits (4094 addresses) here.
+ *
+ * For fewer hosts per overlay subnet (permitting a larger number of
+ * underlay hosts to participate), the underlay netmask may be made
+ * smaller.
+ *
+ * E.g., underlay host 10.111.1.2/12 (network 10.96.0.0/12, host portion
+ * is 0.15.1.2, 20 bits) with an overlay of 33.0.0.0/8 would left shift
+ * the 20 bits of host by 4 (so that it's highest order bit is adjacent to
+ * the lowest order bit of the /8 overlay).  This yields an overlay subnet
+ * of 33.240.16.32/28 (8 bits overlay, 20 bits from the host portion of
+ * the underlay).  This provides more addresses for the underlay network
+ * (approximately 2^20), but each host's segment of the overlay provides
+ * only 4 bits of addresses (14 usable).
+ *
+ * It is also possible to adjust the overlay subnet.
+ *
+ * For an overlay of 240.0.0.0/5 and underlay of 10.88.0.0/20, consider
+ * underlay host 10.88.129.2; the 12 bits of host, 0.0.1.2, are left
+ * shifted 15 bits (/20 - /5), yielding an overlay network of
+ * 240.129.0.0/17.  An underlay host of 10.88.244.215 would yield an
+ * overlay network of 242.107.128.0/17.
+ *
+ * For an overlay of 100.64.0.0/10 and underlay of 10.224.220.0/24, for
+ * underlay host 10.224.220.10, the underlay host portion (.10) is left
+ * shifted 14 bits, yielding an overlay network subnet of 100.66.128.0/18.
+ * This would permit 254 addresses on the underlay, with each overlay
+ * segment providing approximately 2^14 - 2 addresses (16382).
+ *
+ * For packets being encapsulated, the overlay network destination IP
+ * address is deconstructed into its overlay and underlay-derived
+ * portions.  The underlay portion (determined by the overlay mask and
+ * overlay subnet mask) is right shifted according to the size of the
+ * underlay network mask.  This value is then ORed with the network
+ * portion of the underlay network to produce the underlay network
+ * destination for the encapsulated datagram.
+ *
+ * For example, using the initial example of underlay 10.88.3.4/16 and
+ * overlay 99.0.0.0/8, with underlay host 10.88.3.4/16 providing overlay
+ * subnet 99.3.4.0/24 with specfic host 99.3.4.5.  A datagram from
+ * 99.3.4.5 to 99.6.7.8 would first have the underlay host derived portion
+ * of the address extracted.  This is a number of bits equal to underlay
+ * network host portion.  In the destination address, the highest order of
+ * these bits is one bit lower than the lowest order bit from the overlay
+ * network mask.
+ *
+ * Using the sample value, 99.6.7.8, the overlay mask is /8, and the
+ * underlay mask is /16 (leaving 16 bits for the host portion).  The bits
+ * to be shifted are the middle two octets, 0.6.7.0, as this is 99.6.7.8
+ * ANDed with the mask 0x00ffff00 (which is 16 bits, the highest order of
+ * which is 1 bit lower than the lowest order overlay address bit).
+ *
+ * These octets, 0.6.7.0, are then right shifted 8 bits, yielding 0.0.6.7.
+ * This value is then ORed with the underlay network portion,
+ * 10.88.0.0/16, providing 10.88.6.7 as the final underlay destination for
+ * the encapuslated datagram.
+ *
+ * Another transform using the final example: overlay 100.64.0.0/10 and
+ * underlay 10.224.220.0/24.  Consider overlay address 100.66.128.1
+ * sending a datagram to 100.66.200.5.  In this case, 8 bits (the host
+ * portion size of 10.224.220.0/24) beginning after the 100.64/10 overlay
+ * prefix are masked off, yielding 0.2.192.0.  This is right shifted 14
+ * (32 - 10 - (32 - 24), i.e., the number of bits between the overlay
+ * network portion and the underlay host portion) bits, yielding 0.0.0.11.
+ * This is ORed with the underlay network portion, 10.224.220.0/24, giving
+ * the underlay destination of 10.224.220.11 for overlay destination
+ * 100.66.200.5.

+.br
+.SH DESCRIPTION
+\fBhv_kvp_daemon\fP
+is the userspace component of the Hyper-V key value pair functionality,
+communicating via a netlink socket with the kernel HV-KVP driver.
+This pairing allows the Hyper-V host to pass configuration information
+(such as IP addresses) to the guest and allows the host to obtain guest
+version information.

+11. file.o: warning: unannotated intra-function call
+
+   This warning means that a direct call is done to a destination which
+   is not at the beginning of a function. If this is a legit call, you
+   can remove this warning by putting the ANNOTATE_INTRA_FUNCTION_CALL
+   directive right before the call.
+

 If the error doesn't seem to make sense, it could be a bug in objtool.
 Feel free to ask the objtool maintainer for help.

+#
+# For ingress, this means first iteration has iifname of lower/real
+# device.  In this script, thats veth0.
+# Second iteration is iifname set to vrf device, tvrf in this script.

+# For egress, this is reversed: first iteration has the vrf device,

+# test_ct_zone_in demonstrates unexpected change of nftables
+# behavior # caused by commit 09e856d54bda5f28 "vrf: Reset skb conntrack
+# connection on VRF rcv"
+#
+# It was possible to assign conntrack zone to a packet (or mark it for
+# `notracking`) in the prerouting chain before conntrack, based on real iif.
+#
+# After the change, the zone assignment is lost and the zone is assigned based
+# on the VRF master interface (in case such a rule exists).
+# assignment is lost. Instead, assignment based on the `iif` matching
+# Thus it is impossible to distinguish packets based on the original
+# interface.
+#
+# test_masquerade_vrf and test_masquerade_veth0 demonstrate the problem
+# that was supposed to be fixed by the commit mentioned above to make sure
+# that any fix to test case 1 won't break masquerade again.

+Exar USB Serial Driver
+======================
+Version 1A, 1/9/2015
+
+This driver will work with any USB UART function in these Exar devices:
+	XR21V1410/1412/1414
+	XR21B1411
+	XR21B1420/1422/1424
+	XR22801/802/804
+
+The source code has been tested on various Linux kernels from 3.6.x to 3.17.x.  
+This may also work with newer kernels as well.  
+
+
+Installation
+------------
+
+* Compile and install the common usb serial driver module
+
+	# make
+	# insmod ./xr_usb_serial_common.ko
+
+
+* Plug the device into the USB host.  You should see up to four devices created,
+  typically /dev/ttyXRUSB[0-3].
+
+
+Tips for Debugging
+------------------
+
+* Check that the USB UART is detected by the system
+
+	# lsusb
+
+* Check that the CDC-ACM driver was not installed for the Exar USB UART
+
+	# ls /dev/tty*
+
+	To remove the CDC-ACM driver and install the driver:
+
+	# rmmod cdc-acm
+	# modprobe -r usbserial
+	# modprobe usbserial
+	# insmod ./xr_usb_serial_common.ko
+
+
