Revision 65b4711ff513767341aa1915c822de6ec0de65cb authored by Will Deacon on 02 September 2010, 08:32:08 UTC, committed by Russell King on 02 September 2010, 15:36:42 UTC
The validate_event function in the ARM perf events backend has the
following problems:
1.) Events that are disabled count towards the cost.
2.) Events associated with other PMUs [for example, software events or
breakpoints] do not count towards the cost, but do fail validation,
causing the group to fail.
This patch changes validate_event so that it ignores events in the
PERF_EVENT_STATE_OFF state or that are scheduled for other PMUs.
