Subject: [PATCH v3 20/27] perf tests: Add hybrid cases for 'Roundtrip evsel->name' test
Date:   Mon, 29 Mar 2021 15:00:39 +0800
Message-Id: <20210329070046.8815-21-yao.jin@linux.intel.com>
In-Reply-To: <20210329070046.8815-1-yao.jin@linux.intel.com>
References: <20210329070046.8815-1-yao.jin@linux.intel.com>
Precedence: bulk

Since for one hw event, two hybrid events are created.

For example,

evsel->idx      evsel__name(evsel)
0               cycles
1               cycles
2               instructions
3               instructions
...

So for comparing the evsel name on hybrid, the evsel->idx
needs to be divided by 2.

  # ./perf test 14
  14: Roundtrip evsel->name                                           : Ok
