[Xen-devel] [PATCH 1/4] CPUIDLE: Avoid remnant HPET intr while force hpetbroadcast
CPUIDLE: Avoid remnant HPET intr while force hpetbroadcast Exit from C3 is mainly caused by HPET intr if force enable hpetbroadcast. But it is still probably caused by other unexpected events. In this case the HPET timer may still be alive while there is no CPU in C3. Avoid those remnant HPET intr can save cpu handling time and increase idle time.
