Message-Id: <20150515154333.712161952@infradead.org> Date: Fri, 15 May 2015 17:43:33 +0200 From: Peter Zijlstra <peterz@...radead.org> To: mingo@...nel.org, riel@...hat.com Cc: dedekind1@...il.com, linux-kernel@...r.kernel.org, mgorman@...e.de, peterz@...radead.org, rostedt@...dmis.org, juri.lelli@....com Subject: [RFC][PATCH 0/4] sched,numa: pinned task accounting Hi, Here's a first few patches that provide pinned task accounting; they are boot tested only so far. I don't think this is enough to address Artem's regression, but its a foundation to add some more smarts. In particular we should make it harder still to migrate well placed tasks away due to these pinned tasks. Rostedt, Juri, please double check what I did to your resp. set_cpus_allowed methods. --- include/linux/kthread.h | 1 + include/linux/sched.h | 7 ----- kernel/kthread.c | 20 ++++++++++++--- kernel/sched/core.c | 66 ++++++++++++++++++++++++++++++++++++++++++------ kernel/sched/deadline.c | 35 ++----------------------- kernel/sched/fair.c | 43 +++++++++++++++++++++++++------ kernel/sched/idle_task.c | 1 + kernel/sched/rt.c | 41 +----------------------------- kernel/sched/sched.h | 3 +++ kernel/sched/stop_task.c | 1 + kernel/workqueue.c | 11 ++------ 11 files changed, 121 insertions(+), 108 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
