From 7dfd2106230977845705617a25773803c1ce2e5a Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Mon, 24 Jun 2019 12:37:11 -0700 Subject: [PATCH 014/201] perf stat: Fix metrics with --no-merge mainline inclusion from mainline-v5.3-rc1 commit e3a9427323a53ceee540276a74af7706f350d052 category: feature bugzilla: e3a9427323a53ceee540276a74af7706f350d052 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e3a9427323a53ceee540276a74af7706f350d052 ---------------------------------------------------------------------- Since Fixes: 8c5421c016a4 ("perf pmu: Display pmu name when printing unmerged events in stat") using --no-merge adds the PMU name to the evsel name. This breaks the metric value lookup because the parser doesn't know about this. Remove the extra postfixes for the metric evaluation.
