Subject: [PATCH v6 24/26] perf tests: Support 'Convert perf time to TSC' test for hybrid
Date: Tue, 27 Apr 2021 15:01:37 +0800 [thread overview]
Message-ID: <20210427070139.25256-25-yao.jin@linux.intel.com> (raw)
In-Reply-To: <20210427070139.25256-1-yao.jin@linux.intel.com>
Since for "cycles:u' on hybrid platform, it creates two "cycles".
So the second evsel in evlist also needs initialization.
With this patch,
# ./perf test 71
71: Convert perf time to TSC : Ok
Signed-off-by: Jin Yao <yao.jin@linux.intel.com>

v6:
- No change.
v5:
- Drop the variable 'hybrid' and use 'if (perf_pmu__has_hybrid())'.
