Subject: Power Scheduler Design
Date: Sun, 7 Sep 2014 14:47:13 +0300	[thread overview]
Message-ID: <20140907114705.GA10470@abel-laptop> (raw)

For a while now, I've started studying the power aware scheduling problem.
And like many other rookies out there I took all the lkml mails related
and read them all (well, almost all) and I saw that there are some
debating on the implementation.I even look over the implementation
proposed of Preeti U Murthy. I also worked (just for fun) for a while on
some ideas of my own (nothing worth sharing, yet) but I have problem
understanding the design requirements. Here is one. 

  Some of you (even Ingo) said  that the scheduler should be the one to
manage the cpu P/C states. In this case the governors of the cpuidle and
cpufreq would not make any sense anymore.  Does that mean they will not
be a part of this scheduling solution anymore?
