Subject: [PATCH v2 24/27] perf tests: Support 'Session topology' test for hybrid
Date: Thu, 11 Mar 2021 15:07:39 +0800 [thread overview]
Message-ID: <20210311070742.9318-25-yao.jin@linux.intel.com> (raw)
In-Reply-To: <20210311070742.9318-1-yao.jin@linux.intel.com>
Force to create one event "cpu_core/cycles/" by default,
otherwise in evlist__valid_sample_type, the checking of
'if (evlist->core.nr_entries == 1)' would be failed.
root@otcpl-adl-s-2:~# ./perf test 41
41: Session topology : Ok
