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. --- linux-lowlatency-6.8.0.orig/debian.lowlatency/config/annotations +++ linux-lowlatency-6.8.0/debian.lowlatency/config/annotations @@ -0,0 +1,42 @@ +# Menu: HEADER +# FORMAT: 4 +# ARCH: amd64 arm64 +# FLAVOUR: amd64-lowlatency arm64-lowlatency arm64-lowlatency-64k +# FLAVOUR_DEP: {'amd64-lowlatency': 'amd64-generic', 'arm64-lowlatency': 'arm64-generic', 'arm64-lowlatency-64k': 'arm64-generic-64k'} + +include "../../debian.master/config/annotations" + +CONFIG_HZ_1000 policy<{'amd64': 'y', 'arm64': 'y'}> +CONFIG_HZ_1000 note<'HZ for lowlatency must be set to 1000 to provide better system responsiveness'> + +CONFIG_HZ_250 policy<{'amd64': 'n', 'arm64': 'n'}> +CONFIG_HZ_250 note<'Override default HZ used in generic'> + +CONFIG_LATENCYTOP policy<{'amd64': 'y', 'arm64': 'y'}> +CONFIG_LATENCYTOP note<'https://lists.ubuntu.com/archives/kernel-team/2014-July/045006.html, LP#1655986'> + +CONFIG_NO_HZ_FULL policy<{'amd64': 'y', 'arm64': 'y'}> +CONFIG_NO_HZ_FULL note<'Enable access to "Full tickless mode" (LP: #2023007)'> + +CONFIG_NO_HZ_IDLE policy<{'amd64': 'n', 'arm64': 'n'}> +CONFIG_NO_HZ_IDLE note<'Disabled in favor of CONFIG_NO_HZ_FULL (LP: #2023007)'> + +CONFIG_PREEMPT policy<{'amd64': 'y', 'arm64': 'y'}> +CONFIG_PREEMPT note<'Enable fully preemptible kernel by default (can be changed at runtime via /sys/kernel/debug/sched/preempt)'> + +CONFIG_PREEMPT_VOLUNTARY policy<{'amd64': 'n', 'arm64': 'n'}> +CONFIG_PREEMPT_VOLUNTARY note<'Disable voluntary preemption model by default (can be changed at runtime via /sys/kernel/debug/sched/preempt)'> + +CONFIG_RCU_LAZY policy<{'amd64': 'y', 'arm64': 'y'}> +CONFIG_RCU_LAZY note<'Batch RCU callbacks and then flush them after a timed delay instead of executing them immediately (LP: #2023007)'> + +CONFIG_RCU_NOCB_CPU policy<{'amd64': 'y', 'arm64': 'y'}> +CONFIG_RCU_NOCB_CPU note<'Move RCU callbacks from softirq context to kthread context (LP: #2023007)'> + +CONFIG_RCU_NOCB_CPU_DEFAULT_ALL policy<{'amd64': 'y', 'arm64': 'y'}> +CONFIG_RCU_NOCB_CPU_DEFAULT_ALL note<'Enable CONFIG_RCU_NOCB_CPU across all CPUs by default (LP: #2023007)'> + + +# ---- Annotations without notes ---- + +CONFIG_TICK_CPU_ACCOUNTING policy<{'amd64': '-', 'arm64': '-'}> --- linux-lowlatency-6.8.0.orig/debian.lowlatency/control.d/flavour-control.stub +++ linux-lowlatency-6.8.0/debian.lowlatency/control.d/flavour-control.stub @@ -0,0 +1,153 @@ +# Items that get replaced: +# FLAVOUR +# DESC +# ARCH +# SUPPORTED +# TARGET +# BOOTLOADER +# =PROVIDES= +# +# Items marked with =FOO= are optional +# +# This file describes the template for packages that are created for each flavour +# in debian/control.d/vars.* +# +# This file gets edited in a couple of places.
