Subject: [PATCH] drm/vc4: plane: Create more planes
|
|
|
|
Let's now create more planes that can be affected to all the CRTCs.
|
|
|
|
vc4 has 3 CRTCs, 1 primary and 1 cursor each, and was having 24 (8
|
|
planes per CRTC) overlays.
|
|
|
|
However, vc5 has 5 CRTCs, so keeping the same logic would put us at 50
|
|
planes which is well above the 32 planes limit imposed by DRM.
|
|
|
|
Using 16 seems like a good tradeoff between staying under 32 and yet
|
|
providing enough planes.
