Hi Lucasz, I have just found that a part of the 1st patch of packing small tasks (Revert "sched: Introduce temporary FAIR_GROUP_SCHED dependency for load-tracking") has disappeared during my rebase and push on my git tree. The consequence is that the branch sched-pack-small-tasks-v3 only working if CONFIG_FAIR_GROUP_SCHED is set in your kernel. I have pushed a new branch with the fixed http://git.linaro.org/gitweb?p=people/vingu/kernel.git;a=shortlog;h=refs/heads/sched-pack-small-tasks-v3-fixed Regards, Vincent >> I will send the patchset to LKML as soon as I will have got all >> figures of my tests on various platform >> >> Regards, >> Vincent >> >> On 30 January 2013 10:23, Lukasz Majewski <l.majew...@samsung.com> >> wrote: >> > Hi Vincent, >> > >> > Thanks for a very fast response. >> > >> >> On 30 January 2013 09:35, Lukasz Majewski <l.majew...@samsung.com> >> >> wrote: >> >> > Dear All, >> >> > >> >> > >> >> > I'd like to ask about the power aware scheduler development: >> >> > >> >> > https://blueprints.launchpad.net/linaro-power-kernel/+spec/power-aware- >> >> > scheduler >> >> > >> >> > >> >> > >> >> > Why I'm interested? >> >> > >> >> > >> >> > >> >> > I'd like to test and further develop methods to put CPU to IDLE >> >> > or changing its operating frequency.
