[Xen-devel] [PATCH 2/2] CPUIDLE: 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 stopped during C2.
