[PATCH v7 2/2] drm/i915: Adding YUV444 packed format(DRM_FORMAT_XYUV) support.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
