Subject: BFS v0.312 configurable CPU scheduler for 2.6.32
Date: Sat, 19 Dec 2009 02:44:48 +1100	[thread overview]
Message-ID: <200912190244.48911.kernel@kolivas.org> (raw)
In-Reply-To: <200912141516.54725.bzolnier@gmail.com>

As requested, BFS has been made a simple config option to enable/disable in 
kernel build. It is otherwise unchanged from .311. 

http://ck.kolivas.org/patches/bfs/2.6.32-sched-bfs-312.patch

A quick set of kernbench benchmarks on my quad core:

http://ck.kolivas.org/patches/bfs/kernbench2.6.32BFSvCFS.log

Note one person has had problems with preemptible tree based hierarchical rcu 
and bfs 311 using high amounts of CPU, the cause of which remains unknown at 
the moment. Probably safest to not use this combination for now.

Be nice,
enjoy!
