Subject: [PATCH v7 6/8] perf cs-etm: Add traceID in packet
Date: Tue, 29 Jan 2019 20:28:40 +0800 [thread overview]
Message-ID: <20190129122842.32041-7-leo.yan@linaro.org> (raw)
In-Reply-To: <20190129122842.32041-1-leo.yan@linaro.org>
Add traceID in packet, thus we can use traceID to retrieve metadata
pointer from traceID-metadata tuple.
Signed-off-by: Leo Yan <leo.yan@linaro.org>
