Ingo, Please pull the timers/nohz-irq-work-v7 branch that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git timers/nohz-irq-work-v7 It has been acked by Peterz. --- Summary --- This set moves the nohz kick, used to notify a full dynticks CPU when events require tick rescheduling, out of the scheduler tick to a dedicated IPI. This debloats a bit the scheduler IPI from off-topic work that was abusing that scheduler fast path for its convenient asynchronous properties. Now the nohz kick uses irq work for its own needs. Of course this implied quite some background infrastructure rework, including: * Clean up some irq work internals * Implement remote irq work * Implement nohz kick on top of remote irq work * Move full dynticks timer enqueue notification to new kick * Move multi-task notification to new kick * Remove unecessary barriers on multi-task notification Thanks, Frederic --- Frederic Weisbecker (6): irq_work: Split raised and lazy lists irq_work: Implement remote queueing nohz: Support nohz full remote kick nohz: Switch to nohz full remote kick on timer enqueue nohz: Use nohz own full kick on 2nd task enqueue nohz: Use IPI implicit full barrier against rq->nr_running r/w include/linux/irq_work.h | 5 ++++ include/linux/tick.h | 9 +++++- kernel/irq_work.c | 76 ++++++++++++++++++++++++++++++------------------ kernel/sched/core.c | 22 ++++++++------ kernel/sched/sched.h | 12 ++++++-- kernel/smp.c | 9 ++++++ kernel/time/tick-sched.c | 10 ++++--- 7 files changed, 97 insertions(+), 46 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
