On AMD display HW, 3D LUT comes after a shaper curve and we always have to program a shaper curve to delinearize or normalize the color space before applying a 3D LUT (since we have a reduced number of LUT entries). In this version, the default values of 3D LUT for size and bit_depth are 17x17x17 and 12-bit, but we already provide here a more generic mechanisms to program other supported values (9x9x9 size and 10-bit). v2: - started with plane 3D LUT instead of CRTC 3D LUT support v4: - lut3d_size is the max dimension size instead of # of entries Reviewed-by: Harry Wentland Signed-off-by: Melissa Wen --- .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 1 + .../amd/display/amdgpu_dm/amdgpu_dm_color.c | 102 +++++++++++++++++- 2 files changed, 99 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c index c94fdb3478c7..83b1440ad69a 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -8156,6 +8156,7 @@ static void amdgpu_dm_commit_planes(struct drm_atomic_state *state, bundle->surface_updates[planes_count].gamut_remap_matrix = &dc_plane->gamut_remap_matrix; bundle->surface_updates[planes_count].hdr_mult = dc_plane->hdr_mult; bundle->surface_updates[planes_count].func_shaper = dc_plane->in_shaper_func; + bundle->surface_updates[planes_count].lut3d_func = dc_plane->lut3d_func; } amdgpu_dm_plane_fill_dc_scaling_info(dm->adev, new_plane_state, diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_color.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_color.c index 8239904f9d90..f55e0a69dd32 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_color.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_color.c @@ -623,6 +623,86 @@ amdgpu_tf_to_dc_tf(enum amdgpu_transfer_function tf) } } +static void __to_dc_lut3d_color(struct dc_rgb *rgb, + const struct drm_color_lut lut, + int bit_precision) +{ + rgb->red = drm_color_lut_extract(lut.red, bit_precision); + rgb->green = drm_color_lut_extract(lut.green, bit_precision); + rgb->blue = drm_color_lut_extract(lut.blue, bit_precision); +} + +static void __drm_3dlut_to_dc_3dlut(const struct drm_color_lut *lut, + uint32_t lut3d_size, + struct tetrahedral_params *params, + bool use_tetrahedral_9, + int bit_depth) +{ + struct dc_rgb *lut0; + struct dc_rgb *lut1; + struct dc_rgb *lut2; + struct dc_rgb *lut3; + int lut_i, i; + + + if (use_tetrahedral_9) { + lut0 = params->tetrahedral_9.lut0; + lut1 = params->tetrahedral_9.lut1; + lut2 = params->tetrahedral_9.lut2; + lut3 = params->tetrahedral_9.lut3; + } else { + lut0 = params->tetrahedral_17.lut0; + lut1 = params->tetrahedral_17.lut1; + lut2 = params->tetrahedral_17.lut2; + lut3 = params->tetrahedral_17.lut3; + } + + for (lut_i = 0, i = 0; i < lut3d_size - 4; lut_i++, i += 4) { + /* + * We should consider the 3D LUT RGB values are distributed + * along four arrays lut0-3 where the first sizes 1229 and the + * other 1228.
