Subject: [PATCH 48/89] drm/vc4: crtc: Move the cob allocation outside of bind
Date: Mon, 24 Feb 2020 10:06:50 +0100 [thread overview]
Message-ID: <01ce49d16657b6ec1fc674d9a31d4b357a9474cc.1582533919.git-series.maxime@cerno.tech> (raw)
In-Reply-To: <cover.6c896ace9a5a7840e9cec008b553cbb004ca1f91.1582533919.git-series.maxime@cerno.tech>
The COB allocation depends on the HVS channel used for a given
pixelvalve.
While the channel allocation was entirely static in vc4, vc5 changes
that and at bind time, a pixelvalve can be assigned to multiple
HVS channels.
Let's prepare that rework by allocating the COB when it's actually
needed.
