Subject: [PATCH v6 6/8] perf cs-etm: Add traceID in packet
Date: Sat, 19 Jan 2019 09:43:45 +0800	[thread overview]
Message-ID: <20190119014347.27441-7-leo.yan@linaro.org> (raw)
In-Reply-To: <20190119014347.27441-1-leo.yan@linaro.org>

Add traceID in packet, thus we can use traceID to retrieve metadata
pointer from traceID-metadata tuple.
