[PATCH 11/11] perf, tools, stat: Add extra output of counter values with -v

From: Andi Kleen
Date: Tue Mar 22 2016 - 19:12:27 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.
