[PATCH] perf, x86: Fix Haswell CYCLE_ACTIVITY.* counter constraints

From: Andi Kleen
Date: Mon Mar 09 2015 - 14:20:28 EST


From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

Some of the CYCLE_ACTIVITY.* events can only be scheduled on
counter 2. Due to a typo Haswell matched those with
INTEL_EVENT_CONSTRAINT, which lead to the events never
matching as the comparison does not expect anything
in the umask too. Fix the typo.
