Subject: [PATCH] drm/object: Add default color encoding and range
|
|
value at reset
|
|
|
|
Upstream commit 9a48ab11714c955456fefdd4ab532d324fbef563
|
|
|
|
The drm_plane_create_color_properties() function asks for an initial
|
|
value for the color encoding and range, and will set the associated
|
|
plane state variable with that value if a state is present.
|
|
|
|
However, that function is usually called at a time where there's no
|
|
state yet. Since the drm_plane_state reset helper doesn't take care of
|
|
reading that value when it's called, it means that in most cases the
|
|
initial value will be 0 (so DRM_COLOR_YCBCR_BT601 and
|
|
DRM_COLOR_YCBCR_LIMITED_RANGE, respectively), or the drivers will have
|
|
to work around it.
|
|
|
|
Let's add some code in __drm_atomic_helper_plane_state_reset() to get
|
|
the initial encoding and range value if the property has been attached
|
|
in order to fix this.
