The perf_pmu__parse_* functions for the sysfs files of pmu event’s scale, unit, per-pkg and snapshot were updated in commit7b723dbb96("perf pmu: Be lazy about loading event info files from sysfs"). However, the paths for these sysfs files were incorrect. This resulted in perf stat reporting values with wrong scaling and missing units. This is fixed by correcting the paths for these sysfs files. Before this fix: $sudo perf stat -e power/energy-pkg/ -- sleep 2 Performance counter stats for 'system wide': 351,217,188,864 power/energy-pkg/ 2.004127961 seconds time elapsed After this fix: $sudo perf stat -e power/energy-pkg/ -- sleep 2 Performance counter stats for 'system wide': 80.58 Joules power/energy-pkg/ 2.004009749 seconds time elapsed Fixes:7b723dbb96("perf pmu: Be lazy about loading event info files from sysfs") Signed-off-by: Wyes Karny <wyes.karny@amd.com> Reviewed-by: Ian Rogers <irogers@google.com> Cc: ravi.bangoria@amd.com Cc: sandipan.das@amd.com Cc: james.clark@arm.com Cc: kan.liang@linux.intel.com Link: https://lore.kernel.org/r/20230920122349.418673-1-wyes.karny@amd.com Signed-off-by: Namhyung Kim <namhyung@kernel.org>
