Hi Lukasz, I still need to get figures for the cover letter of the V3 of packing small tasks patches. Nevertheless, the patches series is available here: http://git.linaro.org/gitweb?p=people/vingu/kernel.git;a=shortlog;h=refs/heads/sched-pack-small-tasks-v3
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.
