Subject: [PATCH 6/6] perf cs-etm: Print the decoder name
Date: Wed, 21 Jul 2021 10:07:05 +0100	[thread overview]
Message-ID: <20210721090706.21523-7-james.clark@arm.com> (raw)
In-Reply-To: <20210721090706.21523-1-james.clark@arm.com>

Use the real name of the decoder instead of hard-coding "ETM" to avoid
confusion when the trace is ETE. This also now distinguishes between
ETMv3 and ETMv4.
