Please treat :
[PATCH -tip] perf_counter tools: add support to set of multiple events in one short
as
[PATCH 1/2-tip] perf_counter tools: add support to set of multiple events in one short
And here is 2/2 :
[PATCH 2/2 -tip] perf_counter tools: Add support for all CACHE events
Add support for all CACHE events :
perf stat -e all-cache-events
perf stat -e cache-events
On AMD box (<not-counted> events are not available for AMD):
./perf stat -e all-cache-events -- ls -lR /usr/include/ > /dev/null
