u32 XDp_TxMainStreamAttributes::BitsPerColor

Number of bits per color component.

u8 XDp_TxMainStreamAttributes::ComponentFormat

The component format currently in use by the video stream.

u32 XDp_TxMainStreamAttributes::DataPerLane

Used to translate the number of pixels per line to the native internal 16-bit datapath.

u8 XDp_TxMainStreamAttributes::DynamicRange

The dynamic range currently in use by the video stream.

u32 XDp_TxMainStreamAttributes::HStart

Horizontal blank start (in pixels).

u32 XDp_TxMainStreamAttributes::InitWait

Number of initial wait cycles at the start of a new line by the framing logic.

u32 XDp_TxMainStreamAttributes::Misc0

Miscellaneous stream attributes 0 as specified by the DisplayPort 1.2 specification.

u32 XDp_TxMainStreamAttributes::Misc1
