And In order to support DP HDR10, we have to support VSC SDP and HDR Metadata Infoframe SDP. As we will use drm member variable of intel_crtc_state.infoframes, we only need to add vsc sdp member variable to intel_crtc_state.infoframes. Because DP SDP payload type does not have common structure like as "union hdmi_infoframe", it adds "struct intel_dp_vsc_sdp" to intel_display_types.h Signed-off-by: Gwan-gyeong Mun --- drivers/gpu/drm/i915/display/intel_display_types.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/drivers/gpu/drm/i915/display/intel_display_types.h b/drivers/gpu/drm/i915/display/intel_display_types.h index 33ba93863488..81112d63342c 100644 --- a/drivers/gpu/drm/i915/display/intel_display_types.h +++ b/drivers/gpu/drm/i915/display/intel_display_types.h @@ -780,6 +780,17 @@ enum intel_output_format { INTEL_OUTPUT_FORMAT_YCBCR444, }; +struct intel_dp_vsc_sdp { + unsigned char sdp_type; /* Secondary-data Packet Type */ + unsigned char revision; /* Revision Number */ + unsigned char length; /* Number of Valid Data Bytes */ + enum dp_colorspace colorspace; + enum dp_colorimetry colorimetry; + int bpc; + enum dp_dynamic_range dynamic_range; + enum dp_content_type content_type; +}; + struct intel_crtc_state { /* * uapi (drm) state.
