Subject: [GIT PULL] tick/nohz updates v3
Date: Thu, 13 May 2021 01:29:14 +0200 [thread overview]
Message-ID: <20210512232924.150322-1-frederic@kernel.org> (raw)
Ingo, Thomas,
Please pull the timers/nohz-v3 branch that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
timers/nohz-v3
Changes since v2:
* Add Acks from Peter Zijlstra
* Only bother to fetch task's CPU if the task is queued in
"tick/nohz: Kick only _queued_ task whose tick dependency is updated"
(reported by Peter Zijlstra)
* Correctly indent comment in
"tick/nohz: Kick only _queued_ task whose tick dependency is updated"
(reported by Peter Zijlstra)
* Add Peter's SoB in "tick/nohz: Evaluate the CPU expression after the static key"
* Add "tick/nohz: Call tick_nohz_task_switch() with interrupts disabled"
(from Peter Zijlstra)
* Add "MAINTAINERS: Add myself as context tracking maintainer"
---
Summary:
* Further reduce ticks and IPIs in full dynticks mode.
* Optimize static key based test for a CPU's nohz_full mode
and also tick nohz probe on context switch.
* A few cleanups, Kconfig documentation and maintainership clarification.
HEAD: 380b68819eed62264ad8e54467481ca7003248c3
Thanks,
Frederic
