Subject: [PATCH v4 9/9] perf mem: Support Arm SPE events
Date: Fri, 6 Nov 2020 17:48:53 +0800 [thread overview]
Message-ID: <20201106094853.21082-10-leo.yan@linaro.org> (raw)
In-Reply-To: <20201106094853.21082-1-leo.yan@linaro.org>
This patch adds Arm SPE events for perf memory profiling:
'spe-load': event for only recording memory load ops;
'spe-store': event for only recording memory store ops;
'spe-ldst': event for recording memory load and store ops.
Signed-off-by: Leo Yan <leo.yan@linaro.org>
