Subject: [PATCH V8 09/23] coresight: etm3x: set progbit to stop trace collection
Date: Thu, 14 Jan 2016 14:46:03 -0700 [thread overview]
Message-ID: <1452807977-8069-10-git-send-email-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <1452807977-8069-1-git-send-email-mathieu.poirier@linaro.org>
There is no need to use the event enable's "always false" event to
stop trace collection. For that purpose setting the programming bit
(ETMCR:10) is enough.
