Subject: [PATCH v6 21/26] perf tests: Support 'Track with sched_switch' test for hybrid
Date: Tue, 27 Apr 2021 15:01:34 +0800 [thread overview]
Message-ID: <20210427070139.25256-22-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 number of events in evlist is not expected in next test
steps. Now we just use one event "cpu_core/cycles:u/" for hybrid.
# ./perf test 35
35: Track with sched_switch : 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())'
directly.
