perf tests: Add hybrid cases for 'Roundtrip evsel->name' test
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 Signed-off-by: Jin Yao <yao.jin@linux.intel.com> Reviewed-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Kan Liang <kan.liang@intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20210427070139.25256-20-yao.jin@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
