Subject: [PATCH v1 0/3] perf cs-etm: Add support for callchain
Date: Fri, 30 Aug 2019 14:24:18 +0800	[thread overview]
Message-ID: <20190830062421.31275-1-leo.yan@linaro.org> (raw)

This patch seris adds support for instruction sample's callchain.

Patch 01 is to refactor the instruction size calculation; patch 02
is to add thread stack and callchain support; patch 03 is a minor fixing
for instruction sample generation thus the instruction sample can be
alignment with the callchain generation.
