The CFS patch against v2.6.22-rc2, v2.6.21.1 or v2.6.20.10 can be downloaded from the usual place: http://people.redhat.com/mingo/cfs-scheduler/ In -v14 the biggest user-visible change is increased sleeper fairness (done by Mike Galbraith and myself), which results in better interactivity under load. In particular 3D apps such as compiz/Beryl or games benefit from it and should be less sensitive to other apps running in parallel to them - but plain X benefits from it too. CFS is converging nicely, with no regressions reported against -v13. Changes since -v13: - increase sleeper-fairness (Mike Galbraith, me) - kernel/sched_debug.c printk argument fixes for ia64 (Andrew Morton) - CFS documentation fixes (Pranith Kumar D) - increased the default rescheduling granularity to 3msecs on UP, 6 msecs on 2-way systems - small update_curr() precision fix - added an overview section to Documentation/sched-design-CFS.txt - misc cleanups As usual, any sort of feedback, bugreport, fix and suggestion is more than welcome!
