Subject: [PATCH 345/454] drm/vc4: Check if plane requires background fill
|
|
|
|
commit 3d67b68a6a3c2deb689c29759a20150c668c286e upstream.
|
|
|
|
Considering a single plane only, we have to enable background color
|
|
when the plane has an alpha format and could be blending from the
|
|
background or when it doesn't cover the entire screen.
|
|
|
|
Changes from v1:
|
|
- Drop unrelated change
|
|
- Move needs_bg_fill to plane state
