Plane blend is a post-3D LUT curve that linearizes color space for blending. It may be defined by a user-blob LUT and/or predefined transfer function. As hardcoded curve (ROM) is not supported on blend gamma, we use AMD color module to fill parameters when setting non-linear TF with empty LUT. v2: - rename DRM TFs to AMDGPU TFs Reviewed-by: Harry Wentland Signed-off-by: Joshua Ashton Signed-off-by: Melissa Wen --- .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 1 + .../amd/display/amdgpu_dm/amdgpu_dm_color.c | 55 +++++++++++++++++-- 2 files changed, 52 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 025a7eb5c8aa..d37269a2179e 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -8063,6 +8063,7 @@ static void amdgpu_dm_commit_planes(struct drm_atomic_state *state, 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; + bundle->surface_updates[planes_count].blend_tf = dc_plane->blend_tf; } 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 2c96501d2fc0..f638e5b3a70b 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 @@ -706,6 +706,34 @@ static int amdgpu_dm_atomic_shaper_lut(const struct drm_color_lut *shaper_lut, return ret; } +static int amdgpu_dm_atomic_blend_lut(const struct drm_color_lut *blend_lut, + bool has_rom, + enum dc_transfer_func_predefined tf, + uint32_t blend_size, + struct dc_transfer_func *func_blend) +{ + int ret = 0; + + if (blend_size || tf != TRANSFER_FUNCTION_LINEAR) { + /* DRM plane gamma LUT or TF means we are linearizing color + * space before blending (similar to degamma programming).
