Add support for solid_fill property to drm_plane. In addition, add
support for setting and getting the values for solid_fill.
solid_fill holds data for supporting solid fill planes. The property
accepts an RGB323232 value and the driver data is formatted as such:
struct drm_solid_fill {
u32 r;
u32 g;
u32 b;
};
To enable solid fill planes, userspace must assigned solid_fill to a
property blob containing the following information:
struct drm_solid_fill_info {
u8 version;
u32 r, g, b;
BTW: should we add support for alpha too? DPU hardware supports using
RGBA as a fill colour format, doesn't it?
But then we face the obvious question, how do we communicate to
userspace if the hardware support RGB or RGBA?
};
Changes in V2:
- Changed solid_fill property to a property blob (Simon, Dmitry)
- Added drm_solid_fill struct (Simon)
- Added drm_solid_fill_info struct (Simon)
Changes in V3:
- Corrected typo in drm_solid_fill struct documentation
