drm: Introduce plane and CRTC scaling filter properties

2020-10-21T09:19:54+00:00

Introduce per-plane and per-CRTC scaling filter properties to allow userspace to select the driver's default scaling filter or Nearest-neighbor(NN) filter for upscaling operations on CRTC and plane. Drivers can set up this property for a plane by calling drm_plane_create_scaling_filter() and for a CRTC by calling drm_crtc_create_scaling_filter(). NN filter works by filling in the missing color values in the upscaled image with that of the coordinate-mapped nearest source pixel value. NN filter for integer multiple scaling can be particularly useful for for pixel art games that rely on sharp, blocky images to deliver their distinctive look. changes since: v6: * Move property doc to existing "Standard CRTC Properties" and "Plane Composition Properties" doc comments (Simon) changes since v3: * Refactor code, add new function for common code (Ville) changes since v2: * Create per-plane and per-CRTC scaling filter property (Ville) changes since v1: * None changes since RFC: * Add separate properties for plane and CRTC (Ville) Link: https://github.com/xbmc/xbmc/pull/18194 Link: https://github.com/xbmc/xbmc/pull/18567 Reviewed-by: Ville Syrjälä Reviewed-by: Uma Shankar Acked-by: Simon Ser Acked-by: Daniel Vetter Signed-off-by: Pankaj Bharadiya Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20201020161427.6941-2-pankaj.laxminarayan.bharadiya@intel.com

drm/atomic: Reject FLIP_ASYNC unconditionally

2019-09-18T16:42:57+00:00

It's never been wired up. Only userspace that tried to use it (and didn't actually check whether anything works, but hey it builds) is the -modesetting atomic implementation. And we just shut that up. If there's anyone else then we need to silently accept this flag no matter what, and find a new one. Because once a flag is tainted, it's lost.
