Subject: [PATCH 1/2] perf test: Use generic event for expand_libpfm_events()
Date: Sat, 24 Oct 2020 11:59:17 +0900 [thread overview]
Message-ID: <20201024025918.453431-1-namhyung@kernel.org> (raw)
I found that the UNHALTED_CORE_CYCLES event is only available in the
Intel machines and it makes other vendors/archs fail on the test. As
libpfm4 can parse the generic events like cycles, let's use them.
Fixes: 40b74c30ffb9 ("perf test: Add expand cgroup event test")
Signed-off-by: Namhyung Kim <namhyung@kernel.org>
