From 1f297a6eb2bd90663518cbb6e9e2a3b2add34b73 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 17 Oct 2022 19:02:15 -0700 Subject: perf stat: Allocate evsel->stats->aggr properly The perf_stat_config.aggr_map should have a correct size of the aggregation map. Use it to allocate aggr_counts. Also AGGR_NONE with per-core events can be tricky because it doesn't aggreate basically but it needs to do so for per-core events only. So only per-core evsels will have stats->aggr data. Note that other caller of evlist__alloc_stat() might not have stat_config or aggr_map.
