From 1d6d2bea5b97359ff09a8d793674aab3e5f79023 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 17 Oct 2022 19:02:23 -0700 Subject: perf stat: Add perf_stat_process_percore() The perf_stat_process_percore() is to aggregate counts for an event per-core even if the aggr_mode is AGGR_NONE. This is enabled when user requested it on the command line. To handle that, it keeps the per-cpu counts at first. And then it aggregates the counts that have the same core id in the aggr->counts and updates the values for each cpu back. Later, per-core events will skip one of the CPUs unless percore-show-thread option is given. In that case, it can simply print all cpu stats with the updated (per-core) values.
