TRANS_MSA_MISC (Transcoder Main Stream Attribute Miscellaneous)

All reserved fields in this register are MBZ (must be zero), so it can be

safely written without a prior read.

Public Methods

template <, >

typename SelfType::ValueType colorimetry_top_bit ()

True for Y (luminance)-only and RAW formats.

We don't currently support these color formats.

Defined at line 862 of file ../../src/graphics/display/drivers/intel-display/registers-transcoder.h

template <, >

SelfType & set_colorimetry_top_bit (typename SelfType::ValueType val)

True for Y (luminance)-only and RAW formats.

We don't currently support these color formats.

template <, >

typename SelfType::ValueType colorimetry_in_vsc_sdp ()

If true, the colorimetry information is sent separately, in a VSC SDP.

This must only be used if the sink's DPRX_FEATURE_ENUMERATION_LIST register

has VSC_SDP_EXTENSION_FOR_COLORIMETRY_SUPPORTED set.

Including colorimetry information in the VSC (Video Stream Configuration)

SDP (Secondary Data Packet) is described in the VESA DisplayPort Standard

Version 2.0, Section 2.2.5.6.5 "VSC SDP Payload for Pixel

Encoding/Colorimetry Format", pages 203-205

This field was introduced in DisplayPort 1.3. Prior to that, the underlying

bit was MBZ (must be zero).

We don't currently support this feature.

SelfType & set_stereo_video (typename SelfType::ValueType val)

If the "FS MSA MISC1 Drive Enable" field in the TRANS_STEREO3D_CTL register

is true, this field is ignored, and the display hardware drives the

corresponding MSA bits.

typename SelfType::ValueType interlaced_vertical_total_even ()

True iff the number of lines per interlaced frame (two fields) is even.

DisplayPortMsaBitsPerComponent bits_per_component_select ()

The bpc (number of bits per color component) for the selected format.

Some bpc values are not supported by some colorimetry modes. For example,

the RGB wide gamut fixed point only supports 8, 10, and 12bpc.

SelfType & set_video_stream_clock_sync_with_link_clock (typename SelfType::ValueType val)

If true, the main link clock and video stream clock are synchronous.

Before DisplayPort is enabled, this field must be set to true.
