From: Harry Wentland Date: Sat, 15 Nov 2025 00:01:57 +0000 (-0700) Subject: drm/amd/display: Enable support for PQ 125 EOTF and Inverse X-Git-Url: https://gentwo.org/gitweb/?a=commitdiff_plain;h=ef3d703f64915ec38da5e2737f5234bbb5b89266;p=linux%2F.git drm/amd/display: Enable support for PQ 125 EOTF and Inverse This patchset enables support for the PQ_125 EOTF and its inverse on all existing plane 1D curve colorops, i.e., on DEGAM, SHAPER, and BLND blocks. With this patchset the following IGT subtests are passing: kms_colorop --run plane-XR30-XR30-pq_125_eotf kms_colorop --run plane-XR30-XR30-pq_125_inv_eotf kms_colorop --run plane-XR30-XR30-pq_125_eotf-pq_125_inv_eotf kms_colorop --run plane-XR30-XR30-pq_125_eotf-pq_125_inv_eotf-pq_125_eotf Signed-off-by: Alex Hung Signed-off-by: Harry Wentland Reviewed-by: Daniel Stone Signed-off-by: Simon Ser Link: https://patch.msgid.link/20251115000237.3561250-33-alex.hung@amd.com --- 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 f25a302405f0..30665db34dfd 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 @@ -26,6 +26,7 @@ #include "amdgpu.h" #include "amdgpu_mode.h" #include "amdgpu_dm.h" +#include "amdgpu_dm_colorop.h" #include "dc.h" #include "modules/color/color_gamma.h" @@ -674,6 +675,9 @@ amdgpu_colorop_tf_to_dc_tf(enum drm_colorop_curve_1d_type tf) case DRM_COLOROP_1D_CURVE_SRGB_EOTF: case DRM_COLOROP_1D_CURVE_SRGB_INV_EOTF: return TRANSFER_FUNCTION_SRGB; + case DRM_COLOROP_1D_CURVE_PQ_125_EOTF: + case DRM_COLOROP_1D_CURVE_PQ_125_INV_EOTF: + return TRANSFER_FUNCTION_PQ; default: return TRANSFER_FUNCTION_LINEAR; } @@ -1197,8 +1201,10 @@ __set_colorop_in_tf_1d_curve(struct dc_plane_state *dc_plane_state, struct drm_colorop *colorop = colorop_state->colorop; struct drm_device *drm = colorop->dev; - if (colorop->type != DRM_COLOROP_1D_CURVE || - colorop_state->curve_1d_type != DRM_COLOROP_1D_CURVE_SRGB_EOTF) + if (colorop->type != DRM_COLOROP_1D_CURVE) + return -EINVAL; + + if (!(BIT(colorop_state->curve_1d_type) & amdgpu_dm_supported_degam_tfs)) return -EINVAL; if (colorop_state->bypass) { @@ -1230,7 +1236,7 @@ __set_dm_plane_colorop_degamma(struct drm_plane_state *plane_state, /* 1st op: 1d curve - degamma */ for_each_new_colorop_in_state(state, colorop, new_colorop_state, i) { if (new_colorop_state->colorop == old_colorop && - new_colorop_state->curve_1d_type == DRM_COLOROP_1D_CURVE_SRGB_EOTF) { + (BIT(new_colorop_state->curve_1d_type) & amdgpu_dm_supported_degam_tfs)) { colorop_state = new_colorop_state; break; } @@ -1250,8 +1256,10 @@ __set_colorop_in_shaper_1d_curve(struct dc_plane_state *dc_plane_state, struct drm_colorop *colorop = colorop_state->colorop; struct drm_device *drm = colorop->dev; - if (colorop->type != DRM_COLOROP_1D_CURVE && - colorop_state->curve_1d_type != DRM_COLOROP_1D_CURVE_SRGB_INV_EOTF) + if (colorop->type != DRM_COLOROP_1D_CURVE) + return -EINVAL; + + if (!(BIT(colorop_state->curve_1d_type) & amdgpu_dm_supported_shaper_tfs)) return -EINVAL; if (colorop_state->bypass) { @@ -1287,7 +1295,7 @@ __set_dm_plane_colorop_shaper(struct drm_plane_state *plane_state, /* 2nd op: 1d curve - shaper */ for_each_new_colorop_in_state(state, colorop, new_colorop_state, i) { if (new_colorop_state->colorop == old_colorop && - new_colorop_state->curve_1d_type == DRM_COLOROP_1D_CURVE_SRGB_INV_EOTF) { + (BIT(new_colorop_state->curve_1d_type) & amdgpu_dm_supported_shaper_tfs)) { colorop_state = new_colorop_state; break; } @@ -1314,8 +1322,10 @@ __set_colorop_1d_curve_blend_tf_lut(struct dc_plane_state *dc_plane_state, const struct drm_color_lut *blend_lut = NULL; u32 blend_size = 0; - if (colorop->type != DRM_COLOROP_1D_CURVE && - colorop_state->curve_1d_type != DRM_COLOROP_1D_CURVE_SRGB_EOTF) + if (colorop->type != DRM_COLOROP_1D_CURVE) + return -EINVAL; + + if (!(BIT(colorop_state->curve_1d_type) & amdgpu_dm_supported_blnd_tfs)) return -EINVAL; if (colorop_state->bypass) { @@ -1351,7 +1361,7 @@ __set_dm_plane_colorop_blend(struct drm_plane_state *plane_state, /* 3nd op: 1d curve - blend */ for_each_new_colorop_in_state(state, colorop, new_colorop_state, i) { if (new_colorop_state->colorop == old_colorop && - new_colorop_state->curve_1d_type == DRM_COLOROP_1D_CURVE_SRGB_EOTF) { + (BIT(new_colorop_state->curve_1d_type) & amdgpu_dm_supported_blnd_tfs)) { colorop_state = new_colorop_state; break; } diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_colorop.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_colorop.c index aec67b0546b1..cee7129550f1 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_colorop.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_colorop.c @@ -32,13 +32,16 @@ #include "amdgpu_dm_colorop.h" const u64 amdgpu_dm_supported_degam_tfs = - BIT(DRM_COLOROP_1D_CURVE_SRGB_EOTF); + BIT(DRM_COLOROP_1D_CURVE_SRGB_EOTF) | + BIT(DRM_COLOROP_1D_CURVE_PQ_125_EOTF); const u64 amdgpu_dm_supported_shaper_tfs = - BIT(DRM_COLOROP_1D_CURVE_SRGB_INV_EOTF); + BIT(DRM_COLOROP_1D_CURVE_SRGB_INV_EOTF) | + BIT(DRM_COLOROP_1D_CURVE_PQ_125_INV_EOTF); const u64 amdgpu_dm_supported_blnd_tfs = - BIT(DRM_COLOROP_1D_CURVE_SRGB_EOTF); + BIT(DRM_COLOROP_1D_CURVE_SRGB_EOTF) | + BIT(DRM_COLOROP_1D_CURVE_PQ_125_EOTF); #define MAX_COLOR_PIPELINE_OPS 10
