Subject: [PATCH V4 0/3] time/cpuidle: Support in tick broadcast framework in absence of external clock device
Date: Fri, 07 Feb 2014 13:35:56 +0530 [thread overview]
Message-ID: <20140207075618.17187.20149.stgit@preeti.in.ibm.com> (raw)
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.
