The series adds: - UAPI definition for DRM_COLOROP_FIXED_MATRIX - FIXED_MATRIX_TYPE property support in igt_kms - Colorop helper support for configuring FIXED_MATRIX blocks - Pipe-CRC based tests in kms_color_pipeline - Chamelium frame-capture based tests in kms_chamelium_color_pipeline With this, the SDR plane color pipeline looks like: [YUV Full/Limited -> RGB] -> [1D LUT] A single FIXED_MATRIX colorop handles both full and limited range YCbCr to RGB conversion. Supported FIXED_MATRIX modes: - YCbCr 601 Full to RGB - YCbCr 601 Limited to RGB - YCbCr 709 Full to RGB - YCbCr 709 Limited to RGB - YCbCr 2020 NC Full to RGB - YCbCr 2020 NC Limited to RGB v2: -Naming changes (CSC_FF -> FIXED_MATRIX) v3: -Drop YCbCr limited to full and RGB709 to RGB2020 matrices until we have non-IGT userspace that shows their use -Rename subtests to yuv-rgb-btXXX with limited range variants -Add limited range test coverage v4: -Reuse _test_plane_colorops() for FIXED_MATRIX instead of separate _test_plane_fixed_matrix_colorops() -Store encoding/range in colorop fixed_matrix_info Harry Wentland (1): tests/kms_colorop_helper: Add Fixed Matrix colorop infrastructure Swati Sharma (6): include/drm-uapi: Add DRM_COLOROP_FIXED_MATRIX definition lib/igt_kms: Add FIXED_MATRIX_TYPE colorop property tests/kms_colorop_helper: Add Fixed Matrix enum names table tests/kms_color_pipeline: Add FIXED_MATRIX colorop tests tests/kms_color_pipeline: Remove unused color_depth and drm_format tests/kms_chamelium_color_pipeline: Add FIXED_MATRIX colorop tests include/drm-uapi/drm_mode.h | 11 + lib/igt_kms.c | 1 + lib/igt_kms.h | 1 + .../chamelium/kms_chamelium_color_pipeline.c | 279 ++++++++++++++-- tests/kms_color_pipeline.c | 305 ++++++++++++++++-- tests/kms_colorop_helper.c | 64 ++++ tests/kms_colorop_helper.h | 26 +- 7 files changed, 637 insertions(+), 50 deletions(-) -- 2.25.1
