[Intel-gfx] [PATCH v3 04/17] drm/i915/dp: Add writing of DP SDPs (Secondary Data Packet)
It adds routines that write DP VSC SDP and DP HDR Metadata Infoframe SDP.
In order to pack DP VSC SDP, it adds intel_dp_vsc_sdp_pack() function.
It follows DP 1.4a spec. [Table 2-116: VSC SDP Header Bytes] and
[Table 2-117: VSC SDP Payload for DB16 through DB18]
In order to pack DP HDR Metadata Infoframe SDP, it adds
intel_dp_hdr_metadata_infoframe_sdp_pack() function.
And it follows DP 1.4a spec.
([Table 2-125: INFOFRAME SDP v1.2 Header Bytes] and
[Table 2-126: INFOFRAME SDP v1.2 Payload Data Bytes - DB0 through DB31])
and CTA-861-G spec. [Table-42 Dynamic Range and Mastering InfoFrame].
A machanism and a naming rule of intel_dp_set_infoframes() function
references intel_encoder->set_infoframes() of intel_hdmi.c .
VSC SDP is used for PSR and Pixel Encoding and Colorimetry Formats cases.
Because PSR routine has its own routine of writing a VSC SDP, when the PSR
is enabled, intel_dp_set_infoframes() does not write a VSC SDP.
v3:
- Explicitly disable unused DIPs (AVI, GCP, VS, SPD, DRM. They will be
used for HDMI), when intel_dp_set_infoframes() function will be called.
- Replace a structure name to drm_dp_vsc_sdp from intel_dp_vsc_sdp.
