Subject: [PATCH v3 01/22] sched: set SD_PREFER_SIBLING on MC domain to reduce a domain level
Date: Sat, 5 Jan 2013 16:37:30 +0800 [thread overview]
Message-ID: <1357375071-11793-2-git-send-email-alex.shi@intel.com> (raw)
In-Reply-To: <1357375071-11793-1-git-send-email-alex.shi@intel.com>
The domain flag SD_PREFER_SIBLING was set both on MC and CPU domain at
frist commit b5d978e0c7e79a, and was removed uncarefully when clear up
obsolete power scheduler. Then commit 6956dc568 recover the flag on CPU
domain only. It works, but it introduces a extra domain level since this
cause MC/CPU different.
So, recover the the flag in MC domain too to remove a domain level in
x86 platform.
