Subject: [PATCH 3/6] habanalabs: set ETR as non-secured
Date: Sun, 10 Nov 2019 23:55:30 +0200 [thread overview]
Message-ID: <20191110215533.754-3-oded.gabbay@gmail.com> (raw)
In-Reply-To: <20191110215533.754-1-oded.gabbay@gmail.com>
ETR should always be non-secured as it is used by the users to record
profiling/trace data.
