Commit Message

Lisovskiy, Stanislav Oct. 4, 2018, 12:43 p.m. UTC 
PLANE_CTL_FORMAT_AYUV is already supported, according to hardware
specification.

v2: Edited commit message, removed redundant whitespaces.

v3: Fixed fallthrough logic for the format switch cases.

v4: Yet again fixed fallthrough logic, to reuse code from other case
    labels.

v5: Started to use XYUV instead of AYUV, as we don't use alpha.

v6: Removed unneeded initializer for new XYUV format.

v7: Added scaling support for DRM_FORMAT_XYUV

v8: Edited commit message to be more clear about skl+, renamed
    PLANE_CTL_FORMAT_AYUV to PLANE_CTL_FORMAT_XYUV as this format
    doesn't support per-pixel alpha. Fixed minor code issues.

v9: Moved DRM format check to proper place in intel_framebuffer_init.

v10: Added missing XYUV format to sprite planes for skl+.

v11: Changed DRM_FORMAT_XYUV to be DRM_FORMAT_XYUV8888.

Looks good to me.

Though one thing we probably want to do still is adjust
intel_plane_check_src_coordinates() to allow odd coordinates for
this format. I think we should be able to just replace those
hardcoded numbers in there with fb->format->[hv]sub and it should
just work (tm).
