Subject: [PATCH v5 21/26] perf tests: Support 'Track with sched_switch' test for hybrid
Date:   Fri, 23 Apr 2021 13:35:36 +0800
Message-Id: <20210423053541.12521-22-yao.jin@linux.intel.com>
In-Reply-To: <20210423053541.12521-1-yao.jin@linux.intel.com>
References: <20210423053541.12521-1-yao.jin@linux.intel.com>
Precedence: bulk

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

v5:
 - Drop the variable 'hybrid' and use 'if (perf_pmu__has_hybrid())'
   directly.
