To do this, this patch extends the existing YCBCR 4:2:0 framework by: - Adding new parameter in for YCBCR 4:4:4 enum crtc_iutput_format. - Adding case for YCBCR 4:4:4 in while setting AVI infoframes. - Adding necessary checks in modeset sequence. V3: Added this patch in the series V4: Added r-b from Maarten (for v3) Addressed review comment from Ville: Do not use (config->output_format > CRTC_OUTPUT_RGB) V5: Rebase V6: Rebase and small change, to accommodate changes in patch 2 V6: Fixed checkpatch alignment warnings Cc: Ville Syrjälä Cc: Maarten Lankhorst Signed-off-by: Shashank Sharma --- drivers/gpu/drm/i915/intel_color.c | 3 ++- drivers/gpu/drm/i915/intel_display.c | 13 +++++++++---- drivers/gpu/drm/i915/intel_drv.h | 1 + drivers/gpu/drm/i915/intel_hdmi.c | 2 ++ 4 files changed, 14 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_color.c b/drivers/gpu/drm/i915/intel_color.c index bf9d8f6..5127da2 100644 --- a/drivers/gpu/drm/i915/intel_color.c +++ b/drivers/gpu/drm/i915/intel_color.c @@ -149,7 +149,8 @@ static void ilk_load_csc_matrix(struct drm_crtc_state *crtc_state) if (INTEL_GEN(dev_priv) >= 8 || IS_HASWELL(dev_priv)) limited_color_range = intel_crtc_state->limited_color_range; - if (intel_crtc_state->output_format == INTEL_OUTPUT_FORMAT_YCBCR420) { + if (intel_crtc_state->output_format == INTEL_OUTPUT_FORMAT_YCBCR420 || + intel_crtc_state->output_format == INTEL_OUTPUT_FORMAT_YCBCR444) { ilk_load_ycbcr_conversion_matrix(intel_crtc); return; } else if (crtc_state->ctm) { diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 431c5ca..f3ad411 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -6458,8 +6458,9 @@ static int intel_crtc_compute_config(struct intel_crtc *crtc, return -EINVAL; } - if (pipe_config->output_format == INTEL_OUTPUT_FORMAT_YCBCR420 && - pipe_config->base.ctm) { + if ((pipe_config->output_format == INTEL_OUTPUT_FORMAT_YCBCR420 || + pipe_config->output_format == INTEL_OUTPUT_FORMAT_YCBCR444) && + pipe_config->base.ctm) { /* * There is only one pipe CSC unit per pipe, and we need that * for output conversion from RGB->YCBCR.
