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: http://www.kernelhub.org/?p=2&msg=399516 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 drivers/cpuidle/cpuidle.c | 14 +++-- include/linux/clockchips.h | 15 ++++- kernel/time/Makefile | 2 - kernel/time/clockevents.c | 8 ++- kernel/time/tick-broadcast-hrtimer.c | 105 ++++++++++++++++++++++++++++++++++ kernel/time/tick-broadcast.c | 60 ++++++++++++++++++- kernel/time/tick-internal.h | 6 +- 7 files changed, 189 insertions(+), 21 deletions(-) create mode 100644 kernel/time/tick-broadcast-hrtimer.c -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
