[PATCH v3 34/36] ALSA/dummy: Replace tasklet with softirq hrtimer

From: Thomas Gleixner The tasklet is used to defer the execution of snd_pcm_period_elapsed() to the softirq context. Using the HRTIMER_MODE_SOFT mode invokes the timer callback in softirq context as well which renders the tasklet useless. [o-takashi: avoid stall due to a

[PATCH v3 26/36] hrtimer: Add clock bases and hrtimer mode for soft irq context

hrtimer callback functions are always executed in hard interrupt context. Users of hrtimer which need their timer function to be executed in soft interrupt context, make use of tasklets to get the proper context. Add additional hrtimer clock bases for timers which must expire in softirq context,

[PATCH 1/2] lockdep: finer-grained completion key for kthread

Ideally we'd create the key through a macro at the real callers and pass it all the way down. This would give us better coverage for cases where a bunch of kthreads are created for the same thing. But this gets the job done meanwhile and unblocks our CI. Refining later on is always possible. v2:

[PATCH v3 29/36] hrtimer: Implement SOFT/HARD clock base selection

All prerequisites to handle hrtimers for expiry in either hard or soft interrupt context are in place. Add the missing bit in hrtimer_init() which associates the timer to the hard or the soft irq clock base. Signed-off-by: Anna-Maria Gleixner --- kernel/time/hrtimer.c

[PATCH v3 15/36] hrtimer: Make the remote enqueue check unconditional

hrtimer_cpu_base.expires_next is used to cache the next event armed in the timer hardware. The value is used to check whether an hrtimer can be enqueued remotely. If the new hrtimer is expiring before expires_next, then remote enqueue is not possible as the remote hrtimer hardware cannot be

[PATCH v3 11/36] hrtimer: Store running timer in hrtimer_clock_base

The pointer to the currently running timer is stored in hrtimer_cpu_base before the base lock is dropped and the callback is invoked. This results in two levels of indirections and the upcoming support for softirq based hrtimer requires splitting the "running" storage into soft and hard irq

[PATCH v3 20/36] hrtimer: Unify handling of remote enqueue

hrtimer_reprogram() is conditionally invoked from hrtimer_start_range_ns() when hrtimer_cpu_base.hres_active is true. In the !hres_active case there is a special condition for the nohz_active case: If the newly enqueued timer expires before the first expiring timer on a remote CPU then the

There is a small overlapping conflict to net/rxrpc/call_object.c, it should be easy to resolve. In your tree there was a setup_timer() --> timer_setup() conversion, and in my tree there are new lines adding a lockdep_set_class() call right beforehand. 1) The forcedeth conversion from pci_*()

[PATCH v3 16/36] hrtimer: Make hrtimer_cpu_base.next_timer handling unconditional

hrtimer_cpu_base.next_timer stores the pointer to the next expiring timer in a cpu base. This pointer cannot be dereferenced and is solely used to check whether a hrtimer which is removed is the hrtimer which is the first to expire in the CPU base. If this is the case, then the timer hardware

[PATCH v3 17/36] hrtimer: Make hrtimer_reprogramm() unconditional

hrtimer_reprogram() needs to be available unconditionally for softirq based hrtimers. Move the function and all required struct members out of the CONFIG_HIGH_RES_TIMERS #ifdef. There is no functional change because hrtimer_reprogram() is only invoked when hrtimer_cpu_base.hres_active is true.

[PATCH v3 14/36] hrtimer: Use accesor functions instead of direct access

__hrtimer_hres_active() is now available unconditionally. Replace the direct access to hrtimer_cpu_base.hres_active. No functional change. Signed-off-by: Anna-Maria Gleixner --- kernel/time/hrtimer.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff
