Subject: [PATCH 00/23] RT balance v7
Date: Tue, 04 Dec 2007 15:44:25 -0500 [thread overview]
Message-ID: <20071204204236.3567.65491.stgit@novell1.haskins.net> (raw)
Ingo,
This series applies on GIT commit 2254c2e0184c603f92fc9b81016ff4bb53da622d
(2.6.24-rc4 (ish) git HEAD)
These patches replace v6 + v6b announced here:
http://lkml.org/lkml/2007/11/20/613
and
http://lkml.org/lkml/2007/11/21/226
The series is a collaborative effort between myself and Steven Rostedt.
Changes since v6:
*) cleaned up patch headers
*) fixed some checkpatch errors
*) incorporated v6<x> add-ons to one unified series
Synopsis:
---------------------
Most people don't care about RT tasks, but some of us do, and this series
helps us fix a problem with the current design. We designed carefully to have
negligible impact on non RT code paths, and we believe we have achieved this
goal.
These tests against a 64-way SMP architecture show that the series doesn't
hurt those that don't care about RT tasks, but it helps out those that do.

you can find a tarball of the entire series for your convenience here:
ftp://ftp.novell.com/dev/ghaskins/rt-balance-v7.tar.bz2
also, most of these patches have been incorporated into the later versions of
-rt which you can find in patch form here:
http://www.kernel.org/pub/linux/kernel/projects/rt/
or in prebuilt form here from opensuse-factory:
http://download.opensuse.org/distribution/SL-OSS-factory/inst-source/suse/x86_64/kernel-rt-2.6.24_rc3_git1-3.x86_64.rpm
Please consider for inclusion in the next convenient merge window.
Regards,
-Steven Rostedt, and Gregory Haskins
