From: Andi Kleen <ak@linux.intel.com>
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> --- tools/perf/builtin-stat.c | 8 ++++++++ 1 file changed, 8 insertions(+)
