From 212f3d97abc8be09549de12cedb290f47b4dce5a Mon Sep 17 00:00:00 2001 From: Jin Yao Date: Thu, 8 Jul 2021 09:37:00 +0800 Subject: perf tests: Fix 'Roundtrip evsel->name' on core-only system If the atom CPUs are offlined, the 'cpu_atom' is not valid. Perf will not create two events for one hw event, so the evsel->idx doesn't need to be divided by 2 before comparing.
