^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) * A plane represents an image source that can be blended with or overlayed on
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) * top of a CRTC during the scanout process. Planes take their input data from a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) * &drm_framebuffer object. The plane itself specifies the cropping and scaling
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) * of that image, and where it is placed on the visible are of a display
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) * pipeline, represented by &drm_crtc. A plane can also have additional
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) * properties that specify how the pixels are positioned and blended, like
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) * rotation or Z-position. All these properties are stored in &drm_plane_state.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48) * To create a plane, a KMS drivers allocates and zeroes an instances of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49) * &struct drm_plane (possibly as part of a larger structure) and registers it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) * with a call to drm_universal_plane_init().
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) * Cursor and overlay planes are optional. All drivers should provide one
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) * primary plane per CRTC to avoid surprising userspace too much. See enum
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) * drm_plane_type for a more in-depth discussion of these special uapi-relevant
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 55) * plane types. Special planes are associated with their CRTC by calling
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 56) * drm_crtc_init_with_planes().
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 57) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 58) * The type of a plane is exposed in the immutable "type" enumeration property,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 59) * which has one of the following values: "Overlay", "Primary", "Cursor".
