Subject[PATCH] Staircase cpu scheduler v15 for 2.6.17-rc1*
Date
Patches for the current staircase cpu scheduler (v15) for 2.6.17-rc1 are here:

http://www.kernel.org/pub/linux/kernel/people/ck/patches/staircase/2.6.17-rc1/2.6.17-rc1-staircase-15.patch

and for mm2 here:

http://www.kernel.org/pub/linux/kernel/people/ck/patches/staircase/2.6.17-rc1/2.6.17-rc1-mm2/2.6.17-rc1-mm2-staircase-15.patch

Martin Bligh was kind enough to put the current version of staircase on
2.6.17-rc1 for testing on http://test.kernel.org/

Performance more or less parallels mainline 2.6.17-rc1 (apart from
interactivity as shown here previously where staircase mostly trumps
mainline).

Jens Axboe was also kind enough to do a kernbench run on 4xIA64 which also
showed no performance difference. See
http://article.gmane.org/gmane.linux.kernel.ck/5472 (the 2nd run is staircase
and the attachments seem to be listed twice by gmane)

Just as a reminder of how much less code than the ever increasing complexity
mainline scheduler staircase is, here is a diffstat of the patch for
2.6.17-rc1-mm2:

fs/proc/array.c | 4
include/linux/sched.h | 20 -
kernel/exit.c | 1
kernel/sched.c | 987
