`InterfaceReference`

PINTERFACE_REFERENCE interface reference function that is implemented by the display miniport driver.

`InterfaceDereference`

PINTERFACE_DEREFERENCE interface dereference function that is implemented by the display miniport driver.

`DxgkDdiQueryDPCaps`

Pointer to the display miniport driver's DXGKDDI_QUERYDPCAPS function.

`DxgkDdiGetDPAddress`

Pointer to the display miniport driver's DXGKDDI_GETDPADDRESS function.

`DxgkDdiDPAuxIoTransmission`

Pointer to the display miniport driver's DXGKDDI_DPAUXIOTRANSMISSION function.

`DxgkDdiDPI2CIoTransmission`

Pointer to the display miniport driver's DXGKDDI_DPI2CIOTRANSMISSION function.
