i'm pleased to announce release -v8 of the CFS scheduler patchset. (The main goal of CFS is to implement "desktop scheduling" with as high quality as technically possible.)
The CFS patch against v2.6.21.1 (or against v2.6.20.10) can be downloaded from the usual place: http://people.redhat.com/mingo/cfs-scheduler/ -v7 resolved a couple of important regresisons while not introducing new regressions, so i felt it was time to step forward: -v8 tries to address one of the last (known) frontiers: 3D/OpenGL games^H^H^H applications 'smoothness'. To achieve more scheduling smoothness, -v8 introduces a new 'precise load calculation and smoothing' feature. (A variant of this was suggested by Peter Williams in earlier CFS discussions - thanks Peter!) i was able to reuse the rq->cpu_load[] load average calculation from Peter Williams's smpnice code, and it's thus now utilized on UP too. As a nice side-effect of CFS using a smoothed load metric, apps should also start up faster under load. CFS now utilizes the full range of smpnice metrics. No other fundamental portion of CFS was touched, so the rate of change is moderate: 7 files changed, 140 insertions(+), 79 deletions(-) Changes since -v7: - powerpc debug output and build warning fixes (Balbir Singh) - documentation fixes (Zach Carter) - interactivity: precise load calculation and load smoothing 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/
