It's also more complex to manage and require more computational resources. Since a 3D LUT has a limited number of entries in each dimension we want to use them in an optimal fashion. This means using the 3D LUT in a colorspace that is optimized for human vision, such as sRGB, PQ, or another non-linear space. Therefore, userpace may need one 1D LUT (shaper) before it to delinearize content and another 1D LUT after 3D LUT (blend) to linearize content again for blending. The next patches add these 1D LUTs to the plane color mgmt pipeline. v3: - improve commit message about 3D LUT - describe the 3D LUT entries and size (Harry) v4: - advertise 3D LUT max size as the size of a single-dimension Signed-off-by: Melissa Wen --- drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h | 18 +++++++++++++++ .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h | 9 ++++++++ .../amd/display/amdgpu_dm/amdgpu_dm_color.c | 14 +++++++++++ .../amd/display/amdgpu_dm/amdgpu_dm_plane.c | 23 +++++++++++++++++++ 4 files changed, 64 insertions(+) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h index 62044d41da75..f7adaa52c23f 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h @@ -363,6 +363,24 @@ struct amdgpu_mode_info { * @plane_hdr_mult_property: */ struct drm_property *plane_hdr_mult_property; + /** + * @plane_lut3d_property: Plane property for color transformation using + * a 3D LUT (pre-blending), a three-dimensional array where each + * element is an RGB triplet.
