Subject: [PATCH 0/8] perf: Finer grained full dynticks handling
Date: Tue, 23 Jul 2013 02:30:58 +0200 [thread overview]
Message-ID: <1374539466-4799-1-git-send-email-fweisbec@gmail.com> (raw)
Hi,
This patchset inspires from Peterz patch in http://marc.info/?l=linux-kernel&m=137155182121860
to make perf retain the timer tick less often, ie: only when there are freq events
or when one throttles.
The main purpose is to make the lockup detector work with full dynticks, as I suspect
that distros want to enable both...
You can fetch from:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
perf/nohz
Thanks,
Frederic
