Subject: [PATCH] drm/vc4: Increase number of overlay planes from 16 to 48
|
|
|
|
The HVS can accept an arbitrary number of planes, provided
|
|
that the overall pixel read load is within limits, and
|
|
the display list can fit into the dlist memory.
|
|
|
|
Now that DRM will support 64 planes per device, increase
|
|
the number of overlay planes from 16 to 48 so that the
|
|
dlist complexity can be increased (eg 4x4 video wall on
|
|
each of 3 displays).
