Here is the userspace patch series link: https://github.com/xbmc/xbmc/pull/18567 Background on Integer scaling: Integer scaling (IS) is a nearest-neighbor upscaling technique that simply scales up the existing pixels by an integer (i.e., whole number) multiplier. Nearest-neighbor (NN) interpolation works by filling in the missing color values in the upscaled image with that of the coordinate-mapped nearest source pixel value. Both IS and NN preserve the clarity of the original image. In contrast, traditional upscaling algorithms, such as bilinear or bicubic interpolation, result in blurry upscaled images because they employ interpolation techniques that smooth out the transition from one pixel to another. Therefore, integer scaling is particularly useful for pixel art games that rely on sharp, blocky images to deliver their distinctive look. Many gaming communities have been asking for integer-mode scaling support, some links and background: https://software.intel.com/en-us/articles/integer-scaling-support-on-intel-graphics http://tanalin.com/en/articles/lossless-scaling/ https://community.amd.com/thread/209107 https://www.nvidia.com/en-us/geforce/forums/game-ready-drivers/13/1002/feature-request-nonblurry-upscaling-at-integer-rat/ changes since v6: * Move property doc to existing "Standard CRTC Properties" and "Plane Composition Properties" doc comments (Simon) * Drop 0002 patch Pankaj Bharadiya (4): drm: Introduce plane and CRTC scaling filter properties drm/i915: Introduce scaling filter related registers and bit fields drm/i915/display: Add Nearest-neighbor based integer scaling support drm/i915: Enable scaling filter for plane and CRTC drivers/gpu/drm/drm_atomic_uapi.c | 8 ++ drivers/gpu/drm/drm_blend.c | 13 ++ drivers/gpu/drm/drm_crtc.c | 40 ++++++ drivers/gpu/drm/drm_crtc_internal.h | 3 + drivers/gpu/drm/drm_plane.c | 73 +++++++++++ .../gpu/drm/i915/display/intel_atomic_plane.c | 1 + drivers/gpu/drm/i915/display/intel_display.c | 117 +++++++++++++++++- drivers/gpu/drm/i915/display/intel_display.h | 4 + .../drm/i915/display/intel_display_types.h | 2 + drivers/gpu/drm/i915/display/intel_sprite.c | 15 ++- drivers/gpu/drm/i915/i915_reg.h | 22 ++++ include/drm/drm_crtc.h | 16 +++ include/drm/drm_plane.h | 21 ++++ 13 files changed, 331 insertions(+), 4 deletions(-) -- 2.23.0 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
