Just thought I'd let you know that CFS is working on the PS3

i'm pleased to announce release -v13 of the CFS scheduler patchset. The CFS patch against v2.6.22-rc1, v2.6.21.1 or v2.6.20.10 can be downloaded from the usual place: http://people.redhat.com/mingo/cfs-scheduler/ -v13 is a fixes-only release. It fixes a smaller accounting bug, so if you saw small lags during desktop use under certain workloads then please re-check that workload under -v13 too. It also tweaks SMP load-balancing a bit. (Note: the load-balancing artifact reported by Peter Williams is not a CFS-specific problem and he reproduced it in v2.6.21 too. Nevertheless -v13 should be less prone to such artifacts.) I know about no open CFS regression at the moment, so please re-test -v13 and if you still see any problem please re-report it. Thanks! Changes since -v12: - small tweak: made the "fork flow" of reniced tasks zero-sum - debugging update: /proc/<PID>/sched is now seqfile based and echoing 0 to it clears the maximum-tracking counters. - more debugging counters - small rounding fix to make the statistical average of rounding errors zero - scale both the runtime limit and the granularity on SMP too, and make it dependent on HZ - misc cleanups As usual, any sort of feedback, bugreport, fix and suggestion is more than welcome, Ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
