[PATCH 1/1] x86/perf/intel/cstate: add C-state residency events for Knights Landing

2016-10-04 Thread Lukasz Odzioba
Although KNL does support C1,C6,PC2,PC3,PC6 states, the patch only supports C6,PC2,PC3,PC6, because there is no counter for C1. C6 residency counter MSR on KNL has a different address than other platforms which is handled as a new quirk flag. Signed-off-by: Lukasz Odzioba --- arch/x86/events/int
