[PATCH RFC v3 3/6] sched/idle: Add a generic poll before enter real idle path
...q.
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.
2. do a HV specific idle driver (function)
so far, power management is not exposed to guest.. idle is simple for
KVM guest,
calling "sti" / "hlt"(cpuidle_idle_call() --> default_idle_call())..
thanks Xen guys, who has implemented t...

That's only true for your particular use case.
