Subject: [PATCH v5 11/26] perf parse-events: Compare with hybrid pmu name
Date: Fri, 23 Apr 2021 13:35:26 +0800 [thread overview]
Message-ID: <20210423053541.12521-12-yao.jin@linux.intel.com> (raw)
In-Reply-To: <20210423053541.12521-1-yao.jin@linux.intel.com>
On hybrid platform, user may want to enable event only on one pmu.
Following syntax will be supported:
cpu_core/<event>/
cpu_atom/<event>/
For hardware event, hardware cache event and raw event, two events
are created by default. We pass the specified pmu name in parse_state
and it would be checked before event creation. So next only the
event with the specified pmu would be created.
Signed-off-by: Jin Yao <yao.jin@linux.intel.com>
