The information how much a counter ran in 'perf stat' can be quite interesting for other tools to judge how trustworthy a measurement is. Currently it is only output in non CSV mode. This patches make perf stat always output the running time and the enabled/running ratio in CSV mode. This adds two new fields at the end for each line. I assume that existing tools ignore new fields at the end, so it's on by default. Only CSV mode is affected, no difference otherwise. v2: Add extra print_running function v3: Avoid printing nan v4: Remove some elses and add brackets. v5: Move non CSV case into print_running Signed-off-by: Andi Kleen <ak@linux.intel.com> Reviewed-by: Jiri Olsa <jolsa@redhat.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/r/1426083387-17006-1-git-send-email-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
