Subject: [PATCH 6/7] perf script python: Add addr into perf sample dict
Date: Thu, 31 May 2018 07:32:19 -0300 [thread overview]
Message-ID: <20180531103220.24684-7-acme@kernel.org> (raw)
In-Reply-To: <20180531103220.24684-1-acme@kernel.org>
From: Leo Yan <leo.yan@linaro.org>
ARM CoreSight auxtrace uses 'sample->addr' to record the target address
for branch instructions, so the data of 'sample->addr' is required for
tracing data analysis.
This commit collects data of 'sample->addr' into perf sample dict,
finally can be used for python script for parsing event.
