| |
i'm pleased to announce release -v16 of the CFS scheduler patchset.
The rolled-up CFS patch against v2.6.22-rc4, v2.6.22-rc4-mm2, v2.6.21.4 or v2.6.20.13 can be downloaded from the usual place:
http://people.redhat.com/mingo/cfs-scheduler/
-v16 includes smaller fixes. Continued work on precise /proc CPU accounting of both SCHED_OTHER and RT tasks by Dmitry Adamushko and Balbir Singh. Reniced tasks should now disturb nice-0 tasks even less. Also, i have changed SCHED_BATCH back to its current mainline meaning and have added a SCHED_IDLEPRIO instead (first introduced by Con Kolivas in staircase/RSDL/SD).
Changes since -v15:
- more /proc CPU stats accounting improvements (Dmitry Adamushko, Balbir Singh)
- fix SCHED_BATCH (reported by Con Kolivas)
- update_load_fair() - use 64-bit arithmetics (Dmitry Adamushko)
- fix RT->NORMAL accounting issue raised by Srivatsa Vaddagiri: have correct exec_start stamping. (Dmitry Adamushko)
- check for negative deltas in task_sched_runtime() (Dmitry Adamushko)
- check for large forward-jumping sched_clock()
- cleanup: remove task_struct :: last_ran (Dmitry Adamushko)
- /proc/sched_debug printk fixes (Andrew Morton)
- add SCHED_IDLEPRIO
- consolidate the granularity settings and make them scale together
- improve /proc/sched_debug output
- remove the yield workarounds - the default seems to be working now.
- introduce lower and upper limits for the granularity tunables. Setting them to zero accidentally broke nice levels.
- various small fixes/cleanups
As usual, any sort of feedback, bugreport, fix and suggestion is more than welcome!
