Hi Ingo/Peter, I am trying to understand the complex scheduler code and just found something incorrect (maybe i am not reading it well): File: kernel/sched/fair.c static void prio_changed_fair(struct rq *rq, struct task_struct *p, int oldprio) { if (!p->se.on_rq) return;

[PATCH V2 Resend 3/4] workqueue: Schedule work on non-idle cpu instead of current one

Workqueues queues work on current cpu, if the caller haven't passed a preferred cpu. This may wake up an idle CPU, which is actually not required. This work can be processed by any CPU and so we must select a non-idle CPU here. This patch adds in support in workqueue framework to get preferred CPU

Till now, we weren't migrating a running timer because with migration del_timer_sync() can't detect that the timer's handler yet has not finished. Now, when can we actually to reach to the code (inside __mod_timer()) where base->running_timer == timer ? i.e. We are trying to migrate current timer

[PATCH V2 Resend 1/4] sched: Create sched_select_cpu() to give preferred CPU for power saving

In order to save power, it would be useful to schedule work onto non-IDLE cpus instead of waking up an IDLE one. To achieve this, we need scheduler to guide kernel frameworks (like: timers & workqueues) on which is the most preferred CPU that must be used for these tasks. This routine returns the

[PATCH V2 Resend 2/4] timer: hrtimer: Don't check idle_cpu() before calling get_nohz_timer_target()

Check for current cpu's idleness already done in implementation of sched_select_cpu() which is called by get_nohz_timer_target(). So, no need to call idle_cpu() twice, once from sched_select_cpu() and once from timer and hrtimer before calling get_nohz_timer_target(). This patch removes calls to i
