Subject: [PATCH v6 13/26] perf record: Create two hybrid 'cycles' events by default
Date: Tue, 27 Apr 2021 15:01:26 +0800	[thread overview]
Message-ID: <20210427070139.25256-14-yao.jin@linux.intel.com> (raw)
In-Reply-To: <20210427070139.25256-1-yao.jin@linux.intel.com>

When evlist is empty, for example no '-e' specified in perf record,
one default 'cycles' event is added to evlist.

While on hybrid platform, it needs to create two default 'cycles'
events. One is for cpu_core, the other is for cpu_atom.

This patch actually calls evsel__new_cycles() two times to create
two 'cycles' events.

  # ./perf record -vv -a -- sleep 1

We have to create evlist-hybrid.c otherwise due to the symbol
dependency the perf test python would be failed.

v5 - v6:
 - No change.

v4:
 - Use PERF_TYPE_HARDWARE (v3 uses PERF_TYPE_HARDWARE_PMU).

v3:
 - Move the major code to new created evlist-hybrid.c.
