Windows Driver Kit DDI reference (ns-dispmprt-_kmddod_initialization_data)

_KMDDOD_INITIALIZATION_DATA structure

Description

Contains pointers to functions implemented by a kernel mode display-only driver (KMDOD). The KMDOD's DriverEntry function provides the Microsoft DirectX graphics kernel subsystem with entry points by filling in the members of this structure.

Members

`Version`

A positive integer that indicates the version of the functional interface implemented by the KMDOD. The KMDOD must set this member to DXGKDDI_INTERFACE_VERSION, which is defined in Dispmprt.h.

`DxgkDdiAddDevice`

A pointer to the KMDOD's DxgkDdiAddDevice function.

`DxgkDdiStartDevice`

A pointer to the KMDOD's DxgkDdiStartDevice function.

`DxgkDdiStopDevice`

A pointer to the KMDOD's DxgkDdiStopDevice function.

`DxgkDdiRemoveDevice`

A pointer to the KMDOD's DxgkDdiRemoveDevice function.

`DxgkDdiDispatchIoRequest`

A pointer to the KMDOD's DxgkDdiDispatchIoRequest function.

`DxgkDdiInterruptRoutine`

A pointer to the KMDOD's DxgkDdiInterruptRoutine function.

Note This function pointer has special requirements. For more information, see Remarks.

`DxgkDdiDpcRoutine`

A pointer to the KMDOD's DxgkDdiDpcRoutine function.

Note This function pointer has special requirements. For more information, see Remarks.

`DxgkDdiQueryChildRelations`

A pointer to the KMDOD's DxgkDdiQueryChildRelations function.

`DxgkDdiQueryChildStatus`

A pointer to the KMDOD's DxgkDdiQueryChildStatus function.

`DxgkDdiQueryDeviceDescriptor`

A pointer to the KMDOD's DxgkDdiQueryDeviceDescriptor function.

`DxgkDdiSetPowerState`

A pointer to the KMDOD's DxgkDdiSetPowerState function.

`DxgkDdiNotifyAcpiEvent`

A pointer to the KMDOD's DxgkDdiNotifyAcpiEvent function.

`DxgkDdiResetDevice`

A pointer to the KMDOD's DxgkDdiResetDevice function.

`DxgkDdiUnload`

A pointer to the KMDOD's DxgkDdiUnload function.

`DxgkDdiQueryInterface`

A pointer to the KMDOD's DxgkDdiQueryInterface function.

`DxgkDdiControlEtwLogging`

A pointer to the KMDOD's DxgkDdiControlEtwLogging function.

`DxgkDdiQueryAdapterInfo`

A pointer to the KMDOD's DxgkDdiQueryAdapterInfo function.

`DxgkDdiSetPalette`

A pointer to the KMDOD's DxgkDdiSetPalette function that sets the palette for the display.

`DxgkDdiSetPointerPosition`

A pointer to the KMDOD's DxgkDdiSetPointerPosition function.

`DxgkDdiSetPointerShape`

A pointer to the KMDOD's DxgkDdiSetPointerShape function.

`DxgkDdiEscape`

A pointer to the KMDOD's DxgkDdiEscape function.

`DxgkDdiCollectDbgInfo`

A pointer to the KMDOD's DxgkDdiCollectDbgInfo function.

`DxgkDdiIsSupportedVidPn`

A pointer to the KMDOD's DxgkDdiIsSupportedVidPn function.

`DxgkDdiRecommendFunctionalVidPn`

A pointer to the KMDOD's DxgkDdiRecommendFunctionalVidPn function.

`DxgkDdiEnumVidPnCofuncModality`

A pointer to the KMDOD's DxgkDdiEnumVidPnCofuncModality function.

`DxgkDdiSetVidPnSourceVisibility`

A pointer to the KMDOD's DxgkDdiSetVidPnSourceVisibility function.

`DxgkDdiCommitVidPn`

A pointer to the KMDOD's DxgkDdiCommitVidPn function.

`DxgkDdiUpdateActiveVidPnPresentPath`

A pointer to the KMDOD's DxgkDdiUpdateActiveVidPnPresentPath function.

`DxgkDdiRecommendMonitorModes`

A pointer to the KMDOD's DxgkDdiRecommendMonitorModes function.

`DxgkDdiGetScanLine`

A pointer to the KMDOD's DxgkDdiGetScanLine function.

Note This function pointer has special requirements. For more information, see Remarks.

`DxgkDdiQueryVidPnHWCapability`

A pointer to the KMDOD's DxgkDdiQueryVidPnHWCapability function.

`DxgkDdiPresentDisplayOnly`

A pointer to the KMDOD's DxgkDdiPresentDisplayOnly function.

`DxgkDdiStopDeviceAndReleasePostDisplayOwnership`

A pointer to the KMDOD's DxgkDdiStopDeviceAndReleasePostDisplayOwnership function.

`DxgkDdiSystemDisplayEnable`

A pointer to the KMDOD's DxgkDdiSystemDisplayEnable function.

`DxgkDdiSystemDisplayWrite`

A pointer to the KMDOD's DxgkDdiSystemDisplayWrite function.

`DxgkDdiGetChildContainerId`

A pointer to the KMDOD's DxgkDdiGetChildContainerId function.

`DxgkDdiControlInterrupt`

A pointer to the KMDOD's DxgkDdiControlInterrupt function.

Note This function pointer has special requirements. For more information, see Remarks.

`DxgkDdiSetPowerComponentFState`

A pointer to the KMDOD's DxgkDdiSetPowerComponentFState function.

`DxgkDdiPowerRuntimeControlRequest`

A pointer to the KMDOD's DxgkDdiPowerRuntimeControlRequest function.

`DxgkDdiNotifySurpriseRemoval`

A pointer to the KMDOD's DxgkDdiNotifySurpriseRemoval function.

`DxgkDdiPowerRuntimeSetDeviceHandle`

A pointer to the KMDOD's DxgkDdiPowerRuntimeSetDeviceHandle function.

Remarks

If the kernel mode display-only driver (KMDOD) supports the VSync control feature, it must implement all of the DxgkDdiControlInterrupt, DxgkDdiGetScanLine, DxgkDdiInterruptRoutine, and DxgkDdiDpcRoutine functions and must provide valid function pointers to all of these functions in this structure. Conversely, if the KMDOD does not support the VSync control feature, it must not implement either DxgkDdiControlInterrupt or DxgkDdiGetScanLine functions and must not provide valid function pointers to either of these functions in this structure. For more information, see Saving Energy with VSync Control.
