Adrian Hunter 3b56eecdc7 perf evlist: Fix id index for heterogeneous systems ... [ Upstream commit fc705fecf3 ] perf_evlist__set_sid_idx() updates perf_sample_id with the evlist map index, CPU number and TID. It is passed indexes to the evsel's cpu and thread maps, but references the evlist's maps instead. That results in using incorrect CPU numbers on heterogeneous systems. Fix it by using evsel maps. The id index (PERF_RECORD_ID_INDEX) is used by AUX area tracing when in sampling mode. Having an incorrect CPU number causes the trace data to be attributed to the wrong CPU, and can result in decoder errors because the trace data is then associated with the wrong process. Committer notes: Keep the class prefix convention in the function name, switching from perf_evlist__set_sid_idx() to perf_evsel__set_sid_idx().
