Introduce DRM_COLOROP_FIXED_MATRIX, a new colorop type representing a hardware that performs a fixed matrix operation. Unlike CTM-based colorops, this block does not expose programmable coefficients. Instead, userspace selects one of the predefined hardware modes via a new FIXED_MATRIX_TYPE enum property. Supported modes include common YCbCr->RGB and RGB709->RGB2020 conversions. v5: - Drop YCbCr limited to full and RGB709 to RGB2020 matrices until we have non-IGT userspace that shows their use (Robert) v4: - Add limited-range YCbCr-RGB conversion matrix enums (Robert) - Document matrix values (Pekka) - Clarify RGB709 to RGB2020 is a full-range matrix (Pekka) - Fix confusing "CSC preset" doc (Pekka) v2: - Naming changes (Pekka) v3: - Fix NC matrix enum name and string (Melissa) - Rebase Co-developed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com> Signed-off-by: Harry Wentland <harry.wentland@amd.com> Reviewed-by: Melissa Wen <mwen@igalia.com> Reviewed-by: Harry Wentland <harry.wentland@amd.com> Reviewed-by: Robert Mader <robert.mader@collabora.com> Reviewed-by: Alex Hung <alex.hung@amd.com> Reviewed-by: Pekka Paalanen <pekka.paalanen@collabora.com> Link: https://patch.msgid.link/20260814211816.1219597-2-harry.wentland@amd.com |
