Subject: [PATCH 0989/1002] drm/vc4: Enable bg_fill if there are no planes
|
|
enabled
|
|
|
|
The default was to have enable_bg_fill disabled and the first
|
|
plane set it if it wasn't opaque and covering the whole screen.
|
|
However that meant that if no planes were enabled, then the
|
|
background fill wasn't enabled, and would give a striped
|
|
output from the uninitialised output buffer.
|
|
|
|
Initialise it to enabled to avoid this.
