2018-12-05drm: Add a new plane property to send damage during plane updateLukasz Spintzyk10-1/+244
FB_DAMAGE_CLIPS is an optional plane property to mark damaged regions on the plane in framebuffer coordinates of the framebuffer attached to the plane. The layout of blob data is simply an array of "struct drm_mode_rect". Unlike plane src coordinates, damage clips are not in 16.16 fixed point. As plane src in framebuffer cannot be negative so are damage clips. In damage clip, x1/y1 are inclusive and x2/y2 are exclusive. This patch also exports the kernel internal drm_rect to userspace as drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient to represent damage for current plane size. Driver which are interested in enabling FB_DAMAGE_CLIPS property for a plane should enable this property using drm_plane_enable_damage_clips. v2: - Input validation on damage clips against framebuffer size. - Doc update, other minor changes.

2018-11-27drm/sun4i: frontend: Apply format sub-sampling to CH1 dimensionsPaul Kocialkowski1-8/+16
The frontend comes with two "channels", that can be configured independently. When used in YUV mode, the first channel (CH0) represents the luminance component while the second channel (CH1) represents the chrominance. In RGB mode, both have to be configured the same way. Use variables (with the YUV terminology) for each channel's dimensions, calculating the chroma dimensions from the luma dimensions and the sub-sampling factors from the format description. Since the configured size only has pixel precision, the fractional fixed-point part of the source size is dropped for both components to ensure that the scaling factors are accurate.

The frontend documentation (for the A33) mentions that ARGB is supported as output, but with the alpha component always set to 0xff. In practice, this means that the alpha component cannot be preserved when going through the frontend. Since the information is lost, ARGB is not properly supported. As a result, expose the matching format supported by the frontend (both for input and output) as XRGB instead of ARGB. Since ARGB was the selected format for connecting the frontend to the backend, change it to XRGB to reflect this as well.
