drm: Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ to UAPI Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI as a convenience. Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up through the atomic API, but realizing that userspace is likely to take shortcuts and assume that the enum values are what is sent over the wire. As a result these defines are provided purely as a convenience to userspace applications. Changes since v3: - Switched away from past tense in comments - Add define name change to previously mis-spelled DRM_REFLECT_X comment - Improved the comment for the DRM_MODE_REFLECT_<axis> comment Changes since v2: - Changed define prefix from DRM_MODE_PROP_ to DRM_MODE_ - Fix compilation errors - Changed comment formatting - Deduplicated comment lines - Clarified DRM_MODE_PROP_REFLECT_ comment Changes since v1: - Moved defines from drm.h to drm_mode.h - Changed define prefix from DRM_ to DRM_MODE_PROP_ - Updated uses of the defines to the new prefix - Removed include from drm_rect.c - Stopped using the BIT() macro Signed-off-by: Robert Foss <robert.foss@collabora.com> Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Reviewed-by: Sinclair Yeh <syeh@vmware.com> Acked-by: Liviu Dudau <Liviu.Dudau@arm.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20170519205017.23307-2-robert.foss@collabora.com

drm: Add per-plane pixel blend mode property Pixel blend modes represent the alpha blending equation selection, describing how the pixels from the current plane are composited with the background. Adds a pixel_blend_mode to drm_plane_state and a blend_mode_property to drm_plane, and related support functions. Defines three blend modes in drm_blend.h. Changes since v1: - Moves the blending equation into the DOC comment - Refines the comments of drm_plane_create_blend_mode_property to not enumerate the #defines, but instead the string values - Uses fg.* instead of pixel.* and plane_alpha instead of plane.alpha Changes since v2: - Refines the comments of drm_plane_create_blend_mode_property: 1) Puts the descriptions (after the ":") on a new line 2) Adds explaining why @supported_modes need PREMUL as default Changes since v3: - Refines drm_plane_create_blend_mode_property(). drm_property_add_enum() can calculate the index itself just fine, so no point in having the caller pass it in. - Since the current DRM assumption is that alpha is premultiplied as default, define DRM_MODE_BLEND_PREMULTI as 0 will be better. - Refines some comments. Changes since v4: - Adds comments in drm_blend.h. - Removes setting default value in drm_plane_create_blend_mode_property() as it is already in __drm_atomic_helper_plane_reset(). - Fixes to use state->pixel_blend_mode instead of using plane->state->pixel_blend_mode in reset function. - Rebases on drm-misc-next.

drm/blend: Add a generic alpha property Some drivers duplicate the logic to create a property to store a per-plane alpha. This is especially useful if we ever want to support extra protocols for Wayland like: https://lists.freedesktop.org/archives/wayland-devel/2017-August/034741.html Let's create a helper in order to move that to the core.
