Add pre-defined transfer function to enable delinearizing content with or without shaper LUT, where AMD color module calculates the resulted shaper curve. We apply an inverse EOTF to go from linear values to encoded values. If we are already in a non-linear space and/or don't need to normalize values, we can bypass shaper LUT with a linear transfer function that is also the default TF value. There is no shaper ROM. When setting shaper TF (!= Identity) and LUT at the same time, the color module will combine the pre-defined TF and the custom LUT values into the LUT that's actually programmed. v2: - squash commits for shaper LUT and shaper TF - define inverse EOTF as supported shaper TFs v3: - spell out TF+LUT behavior in the commit and comments (Harry) - replace BT709 EOTF by inv OETF Signed-off-by: Melissa Wen --- drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h | 21 ++++++++++++ .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h | 11 +++++++ .../amd/display/amdgpu_dm/amdgpu_dm_color.c | 29 +++++++++++++++++ .../amd/display/amdgpu_dm/amdgpu_dm_plane.c | 32 +++++++++++++++++++ 4 files changed, 93 insertions(+) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h index 1b5f25989f7f..80ccda0ffc0d 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h @@ -363,6 +363,27 @@ struct amdgpu_mode_info { * @plane_hdr_mult_property: */ struct drm_property *plane_hdr_mult_property; + /** + * @shaper_lut_property: Plane property to set pre-blending shaper LUT + * that converts color content before 3D LUT.
