[PATCH V4 0/3] time/cpuidle: Support in tick broadcast framework inabsence of external clock device

From: Preeti U Murthy
Date: Fri Feb 07 2014 - 03:09:42 EST

This patchset provides support in the tick broadcast framework for such
architectures so as to enable the CPUs to get into deep idle.

Presently we are in need of this support on certain implementations of
PowerPC. This patchset has thus been tested on the same.

This patchset has been based on the idea discussed here:

Changes in V4:
1. Cleared the stand by CPU from the oneshot mask. As a result PATCH 3/3
was simplified.
2. Fixed compile time warnings.

Preeti U Murthy (2):
time: Change the return type of clockevents_notify() to integer
time/cpuidle:Handle failed call to BROADCAST_ENTER on archs with CPUIDLE_FLAG_TIMER_STOP set

Thomas Gleixner (1):
tick/cpuidle: Initialize hrtimer mode of broadcast
