From 660e533e87ff4e66434f90fca987b929d4eb0059 Mon Sep 17 00:00:00 2001 From: Jin Yao Date: Tue, 27 Apr 2021 15:01:29 +0800 Subject: perf stat: Warn group events from different hybrid PMU If a group has events which are from different hybrid PMUs, shows a warning: "WARNING: events in group from different hybrid PMUs!" This is to remind the user not to put the core event and atom event into one group. Next, just disable grouping. # perf stat -e "{cpu_core/cycles/,cpu_atom/cycles/}" -a -- sleep 1 WARNING: events in group from different hybrid PMUs!
