Subject: [PATCH 00/16 v3] timers/nohz cleanups and hotplug reorganization
Date: Sun, 25 Feb 2024 23:54:52 +0100 [thread overview]
Message-ID: <20240225225508.11587-1-frederic@kernel.org> (raw)
Hi,
Here are some cleanups here and there and also some more rational tick
related CPU hotplug code reorganization.
Changes since v3:
* Rebase against latest tip:timers/core (after tmigr introduction)
* New patch "timers: Assert no next dyntick timer look-up while CPU"
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
timers/hotplug-v3
HEAD: a0d432ebab0b7f75e03049d5d2baabff7f39ee1d
Frederic Weisbecker (14):
tick: Remove useless oneshot ifdeffery
tick: Use IS_ENABLED() whenever possible
tick: s/tick_nohz_stop_sched_tick/tick_nohz_full_stop_tick
tick: No need to clear ts->next_tick again
tick: Start centralizing tick related CPU hotplug operations
tick: Move tick cancellation up to CPUHP_AP_TICK_DYING
tick: Move broadcast cancellation up to CPUHP_AP_TICK_DYING
tick: Assume the tick can't be stopped in NOHZ_MODE_INACTIVE mode
tick: Move got_idle_tick away from common flags
tick: Move individual bit features to debuggable mask accesses
tick: Split nohz and highres features from nohz_mode
tick: Shut down low-res tick from dying CPU
tick: Assume timekeeping is correctly handed over upon last offline
idle call
timers: Assert no next dyntick timer look-up while CPU is offline
Peng Liu (2):
tick/nohz: Remove duplicate between tick_nohz_switch_to_nohz() and
tick_setup_sched_timer()
tick/nohz: Remove duplicate between lowres and highres handlers
