Subject: perf stat: Add extra output of counter values with -vv
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0b1abbf4a7d273a13065534d718661fc904703b9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

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
