[PATCH 08/12] perf, tools, stat: Add extra output of counter values with -v
From: Andi Kleen
Date: Tue Jan 19 2016 - 21:30:04 EST
From: Andi Kleen <ak@xxxxxxxxxxxxxxx>
Add debug output of raw counter values per CPU when
perf stat -v is specified, together with their cpu numbers.
This is very useful to debug problems with per core counters,
where we can normally only see aggregated values.
