Constants

D3DBUSTYPE_OTHER

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

D3DBUSTYPE_PCI

PCI bus.

D3DBUSTYPE_PCIX

PCI-X bus.

D3DBUSTYPE_PCIEXPRESS

PCI Express bus.

D3DBUSTYPE_AGP

Accelerated Graphics Port (AGP) bus.

D3DBUSIMPL_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.

D3DBUSIMPL_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.

D3DBUSIMPL_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.

D3DBUSIMPL_MODIFIER_DAUGHTER_BOARD_CONNECTOR

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

D3DBUSIMPL_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.

D3DBUSIMPL_MODIFIER_NON_STANDARD

One of the D3DBUSIMPL_MODIFIER_MODIFIER_Xxx flags is set.

Remarks

As many as three flags can be set. Flags in the range 0x00 through 0x04 (D3DBUSTYPE_Xxx) provide the basic bus type. Flags in the range 0x10000 through 0x50000 (D3DBUSIMPL_MODIFIER_Xxx) modify the basic description. The driver sets one bus-type flag, and can set zero or one modifier flag. If the driver sets a modifier flag, it also sets the D3DBUSIMPL_MODIFIER_NON_STANDARD flag. Flags are combined with a bitwise OR.
