[PATCH RFC v3 3/6] sched/idle: Add a generic poll before enter real idle path
...the data which is necessary to make power/idle
state decisions, is the last idle state's residency time. IIUC this data
is duration from idle to wakeup, which maybe by reschedule irq or other irq.
I also test that the reschedule irq overlap by more than 90% (trace the
need_resched status after cpuidle_idle_call), when I run ctxsw/netperf for
one minute.
as the overlap, I think I can input the last idle state's residency time
to make decisions about probabilistic polling, as @dev->last_residency does.
it is much easier to get data.

Re: [RFC PATCH V4 3/5] cpuidle: default idle driver for x86

Hi Len,
I have basically moved the code for arch default and mwait
idle from arch/x86/kernel/process.c to a driver. This was
suggested by Venki (https://lkml.org/lkml/2010/10/19/460)
as part of pm_idle cleanup and direct call of
cpuidle_idle_call(). There is not much new code here.

That's part of the picture, but not complete.
