Subject: [PATCH 0/4] ARM: add support for context tracking subsystem
Date: Wed, 20 Mar 2013 17:01:57 -0700 [thread overview]
Message-ID: <1363824121-26169-1-git-send-email-khilman@linaro.org> (raw)
commit 91d1aa43 (context_tracking: New context tracking susbsystem)
generalized parts of the RCU userspace extended quiescent state into
the context tracking subsystem. Context tracking is then used
to implement adaptive tickless (a.k.a full nohz)
Mainline currently only includes x86 support for the context tracking
susbsystem and the goal of this series is to add ARM support, in order
to make adaptive tickless functional on ARM.
Depends on the prerequistes series:
[PATCH 0/3] ARM: context tracking support prerequisites
http://marc.info/?l=linux-kernel&m=136382248131438&w=2
Both of which are combined on top of Frederic's 3.9-rc1-nohz1 branch
and available here:
git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux.git arm-nohz-v2/context-tracking
Using this, I tested adaptive tickless on a 2 CPU ARM SoC (OMAP4
Panda.)
