From: Ian Rogers Date: Sun, 5 Oct 2025 18:24:25 +0000 (-0700) Subject: perf test parse-events: Without a PMU use cpu-cycles rather than cycles X-Git-Tag: v6.19-rc1~61^2~188 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2e6dc3b9334cd0d404591009b3d9957edcf2f6cf;p=thirdparty%2Fkernel%2Flinux.git perf test parse-events: Without a PMU use cpu-cycles rather than cycles Without a PMU perf matches an event against any PMU with the event. Unfortunately some PMU drivers advertise a "cycles" event which is typically just a core event. Switch to using "cpu-cycles" which is an indentical legacy event but avoids the multiple PMU confusion introduced by the PMU drivers. Note, on x86 cpu-cycles is also a sysfs event but cycles isn't.
