I am not sure I know the answer, but I have a question which you can answer :) Is it possible for a CPU (which already has high priority deadline activity going on) to be busy enough to be not able to run the schedutil kthread for sometime ? That would be the only case I believe where it would be better to let some other CPU go and change the frequency for this one as we better run faster while we have the high load going on. -- viresh
