Subject: [PATCH 3/3] perf cs-etm: Update deduction of TRCCONFIGR register for branch broadcast
Date: Wed,  8 Dec 2021 16:09:07 +0000	[thread overview]
Message-ID: <20211208160907.749482-3-james.clark@arm.com> (raw)
In-Reply-To: <20211208160907.749482-1-james.clark@arm.com>

Now that a config flag for branch broadcast has been added, take it into
account when trying to deduce what the driver would have programmed the
TRCCONFIGR register to.
