Subject: [PATCH v3 10/27] perf parse-events: Create two hybrid raw events
Date: Mon, 29 Mar 2021 15:00:29 +0800	[thread overview]
Message-ID: <20210329070046.8815-11-yao.jin@linux.intel.com> (raw)
In-Reply-To: <20210329070046.8815-1-yao.jin@linux.intel.com>

On hybrid platform, same raw event is possible to be available on
both cpu_core pmu and cpu_atom pmu. So it's supported to create
two raw events for one event encoding.

  # ./perf stat -e r3c -a -vv -- sleep 1
