perf stat: Add extra output of counter values with -vv
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. v2: Make it depend on -vv, not -v Signed-off-by: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1461787251-6702-12-git-send-email-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
