Subject: [PATCH v2 1/6] perf arm-spe: Enable sample type PERF_SAMPLE_DATA_SRC
Date: Thu, 11 Feb 2021 15:38:51 +0200 [thread overview]
Message-ID: <20210211133856.2137-1-james.clark@arm.com> (raw)
From: Leo Yan <leo.yan@linaro.org>
This patch is to enable sample type PERF_SAMPLE_DATA_SRC for Arm SPE in
the perf data, when output the tracing data, it tells tools that it
