This is the branch I mentioned in my other pull request which contains our improved cpuidle support for the "powernv" platform (non-virtualized). It adds support for the "fast sleep" feature of the processor which provides higher power savings than our usual "nap" mode but at the cost of losing the timers while asleep, and thus exploits the new timer broadcast framework to work around that limitation. It's based on a tip timer tree that you seem to have already merged Cheers, Ben. The following changes since commit 849401b66d305f3feb75b6db7459b95ad190552a: tick: Fixup more fallout from hrtimer broadcast mode (2014-02-09 15:11:47 +0100) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc.git powernv-cpuidle for you to fetch changes up to 0888839c5b62c44a55ac9d28acc273ba663c65ea: cpuidle/powernv: Parse device tree to setup idle states (2014-03-05 15:57:08 +1100) ---------------------------------------------------------------- Preeti U Murthy (3): powerpc: Split timer_interrupt() into timer handling and interrupt handling routines cpuidle/powernv: Add "Fast-Sleep" CPU idle state cpuidle/powernv: Parse device tree to setup idle states Srivatsa S.
