Subject: [PATCH v2 12/34] staging: mmal-vchiq: Add support for event callbacks.
Date: Mon, 4 May 2020 12:25:49 +0300 [thread overview]
Message-ID: <20200504092611.9798-13-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20200504092611.9798-1-laurent.pinchart@ideasonboard.com>
From: Dave Stevenson <dave.stevenson@raspberrypi.org>
(Preparation for the codec driver).
The codec uses the event mechanism to report things such as
resolution changes. It is signalled by the cmd field of the buffer
being non-zero.
Add support for passing this information out to the client.
