Changes since V2:
- remove useless definition for UP platform
- rebased on top of Steven Rostedt's patches :
So what's the status of those patches? I still worry about the extra context switch overhead for the high-frequency idle scenario.
I don't know. I have seen a pulled answer from Ingo but can't find the commits in the tip tree.
Steve, have you got more info about the status of your patches ?
Yeah, I asked Ingo to revert it due to Peter's concerns. I was able to get the latencies I needed without that patch set. That made it not so urgent.
Can you rebase your patches doing something similar? That is, still use the pre/post_schedule_idle() calls, but don't base it off of my patch set.
Thanks,
