[ANNOUNCE] linux-4.11-ck1 / MuQSS CPU scheduler 0.155
These are patches designed to improve system responsiveness and interactivity with specific emphasis on the desktop, but configurable for any workload. The patchset is mainly centred around the Multiple Queue Skiplist Scheduler, MuQSS. linux-4.11-ck1 -ck1 patches: http://ck.kolivas.org/patches/4.0/4.11/4.11-ck1/ Git tree: https://github.com/ckolivas/linux/tree/4.11-ck MuQSS Download: http://ck.kolivas.org/patches/muqss/4.0/4.11/4.11-sched-MuQSS_155.patch Git tree: https://github.com/ckolivas/linux/tree/4.11-muqss 4.11-ck1 full patch list: 0001-Multiple-Queue-Skiplist-Scheduler-version-0.155-for-.patch 0002-Make-preemptible-kernel-default.patch 0003-Expose-vmsplit-for-our-pour-32-bit-users.patch 0004-Create-highres-timeout-variants-of-schedule_timeout-.patch 0005-Special-case-calls-of-schedule_timeout-1-to-use-the-.patch 0006-Convert-msleep-to-use-hrtimers-when-active.patch 0007-Replace-all-schedule-timeout-1-with-schedule_min_hrt.patch 0008-Replace-all-calls-to-schedule_timeout_interruptible-.patch 0009-Replace-all-calls-to-schedule_timeout_uninterruptibl.patch 0010-Make-hrtimer-granularity-and-minimum-hrtimeout-confi.patch 0011-Don-t-use-hrtimer-overlay-when-pm_freezing-since-som.patch 0012-Make-threaded-IRQs-optionally-the-default-which-can-.patch 0013-Reinstate-default-Hz-of-100-in-combination-with-MuQS.patch 0014-Make-writeback-throttling-default-enabled.patch 0015-Swap-sucks.patch 0016-BFQ-v8-for-linux-4.11.patch 0017-Make-BFQ-default-IO-scheduler.patch 0018-Add-ck1-version.patch For a brief description of each patch without trawling the git tree, each patch can be found as a quilt series here: http://ck.kolivas.org/patches/4.0/4.11/4.11-ck1/patches/ MuQSS 0.155 updates: Fixed syscall convention in the code for sched_setscheduler. Fixed copy to user error with max CPUs enabled. Changed skip lists to 25% probability of increased level (from 50%) scaling each CPU up to loads of 64k as a result. Minor preemption code tweak. 4.11-ck1 updates: Cleaned up the patchset. This was the most massive resync I think I can ever recall with the mainline kernel thanks to the complete restructuring of the scheduler code by Mingo. Fortunately there weren't that many actual changes to the scheduler itself that I needed to port but it was still a protracted effort. Probably the most amusing part of the resync was seeing my name mysteriously disappear from the credits of sched/core.c from mainline, although everyone's names were removed along with it. Given the size of this merge, it is possible there are build configurations that fail, so bear with me and post your config if that's the case.
