Subject: [PATCH 31/32] nohz/cpuset: Disable under some configs
Date: Mon, 29 Oct 2012 16:27:42 -0400 [thread overview]
Message-ID: <20121029203851.189035682@goodmis.org> (raw)
In-Reply-To: 20121029202711.062749374@goodmis.org
[-- Attachment #1: 0031-nohz-cpuset-Disable-under-some-configs.patch --]
[-- Type: text/plain, Size: 1782 bytes --]
From: Frederic Weisbecker <fweisbec@gmail.com>
This shows the various things that are not yet handled by
the nohz cpusets: perf events, irq work, irq time accounting.
But there are further things that have yet to be handled:
sched clock tick, runqueue clock, sched_class::task_tick(),
rq clock, cpu load, complete handling of cputimes, ...

This options let you apply a nohz property to a cpuset such
that the periodic timer tick tries to be avoided when possible on
