Thanks to Willy Tarreau for noticing likely fault point. Also requested was a version in the Makefile so this version of the patch adds -sd045 to the kernel version. http://ck.kolivas.org/patches/staircase-deadline/2.6.20.7-sd-0.45.patch http://ck.kolivas.org/patches/staircase-deadline/2.6.21-rc7-sd-0.45.patch Incrementals from 0.44: http://ck.kolivas.org/patches/staircase-deadline/2.6.20.7/sd-0.44-0.45.patch http://ck.kolivas.org/patches/staircase-deadline/2.6.21-rc7/sd-0.44-0.45.patch Renicing X to -10, while not essential, may be desirable on the desktop. Unlike the CFS scheduler which renices X without your intervention to nice -19, the SD patches do not alter nice level on their own. See the patch just posted called 'sched: implement staircase deadline scheduler ymf accounting fixes' for details of the fixes. -- -ck
