[Xen-devel] [PATCH 0/2] CPUIDLE: fixings for multiple C3 & C2 LAPIC stop
[PATCH 1/2] Support multiple C3 states. There may be multiple ACPI C3 states mapped into different CPU C-states.So made some modification to support this case. [PATCH 2/2] Handle C2 LAPIC timer & TSC stop. ACPI C2 is quite possible mapped to CPU C3 or deeper state, so thinking from worst cases, enable C3 like entry/exit handling for C2 by default. Option ''lapic_timer_c2_ok'' can be used to select simple C2 entry/exit only if the user make sure that LAPIC tmr & TSC will not be stop during C2.
