[PATCH 2/3] ARM: perf: clean and update ARMv7 event numbers
Will Deacon
will.deacon at arm.com
Fri Sep 30 06:15:55 EDT 2011
This patch updates the ARMv7 perf event numbers so that:
(1) A consistent naming scheme is used between different CPUs.
(2) Only events actually used by Linux are described.
(3) Where possible, architected events are used in preference to
CPU-specific events.
This results in the removal of a load of unused, hardcoded data and
makes is more clear as to which events are supported on each PMU.
