Hello, In this version I've reduced color keying modes and properties to a bare minimum because considering several modes and properties at once might take quite a lot of effort due to a variety of HW capabilities. This allows us to start easy with the generic colorkey properties support. For the starter let's implement probably the most common (and simple) color keying mode - the "green screen" (or "chroma key") mode. More advanced modes and features could be implemented later on by as needed basis. Following Ville's Syrjälä review comments to v2, the color key value is now given in ARGB16161616 format. Drivers have to convert this 16bpc format into internal color key value representation themselves. This works well for cases where conversion is done to a non-planar integer formats, but I'm not sure how drivers are supposed to cope with cases where conversion involves churning with fixed point math / floating point representation. Comments are welcome. v2: https://lists.freedesktop.org/archives/dri-devel/2018-May/178408.html v1: https://lists.freedesktop.org/archives/dri-devel/2017-December/160510.html Dmitry Osipenko (1): drm/tegra: plane: Implement generic colorkey property for older Tegra's Laurent Pinchart (1): drm: Add generic colorkey properties for DRM planes drivers/gpu/drm/drm_atomic.c | 12 ++++ drivers/gpu/drm/drm_blend.c | 99 +++++++++++++++++++++++++++++++++ drivers/gpu/drm/tegra/dc.c | 25 +++++++++ drivers/gpu/drm/tegra/dc.h | 7 +++ drivers/gpu/drm/tegra/plane.c | 102 ++++++++++++++++++++++++++++++++++ include/drm/drm_blend.h | 3 + include/drm/drm_plane.h | 53 ++++++++++++++++++ 7 files changed, 301 insertions(+) -- 2.17.0 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
