Constants

D3D11_BUS_TYPE_OTHER

Indicates a type of bus other than the types listed here.

D3D11_BUS_TYPE_PCI

PCI bus.

D3D11_BUS_TYPE_PCIX

PCI-X bus.

D3D11_BUS_TYPE_PCIEXPRESS

PCI Express bus.

D3D11_BUS_TYPE_AGP

Accelerated Graphics Port (AGP) bus.

D3D11_BUS_IMPL_MODIFIER_INSIDE_OF_CHIPSET

The implementation for the graphics adapter is in a motherboard chipset's north bridge. This flag implies that data never goes over an expansion bus (such as PCI or AGP) when it is transferred from main memory to the graphics adapter.

D3D11_BUS_IMPL_MODIFIER_TRACKS_ON_MOTHER_BOARD_TO_CHIP

Indicates that the graphics adapter is connected to a motherboard chipset's north bridge by tracks on the motherboard, and all of the graphics adapter's chips are soldered to the motherboard. This flag implies that data never goes over an expansion bus (such as PCI or AGP) when it is transferred from main memory to the graphics adapter.

D3D11_BUS_IMPL_MODIFIER_TRACKS_ON_MOTHER_BOARD_TO_SOCKET

The graphics adapter is connected to a motherboard chipset's north bridge by tracks on the motherboard, and all of the graphics adapter's chips are connected through sockets to the motherboard.

D3D11_BUS_IMPL_MODIFIER_DAUGHTER_BOARD_CONNECTOR

The graphics adapter is connected to the motherboard through a daughterboard connector.

D3D11_BUS_IMPL_MODIFIER_DAUGHTER_BOARD_CONNECTOR_INSIDE_OF_NUAE

The graphics adapter is connected to the motherboard through a daughterboard connector, and the graphics adapter is inside an enclosure that is not user accessible.

D3D11_BUS_IMPL_MODIFIER_NON_STANDARD

One of the D3D11_BUS_IMPL_MODIFIER_Xxx flags is set.
