DXGK_OPM_INTERFACE structure (dispmprt.h)

The DXGK_OPM_INTERFACE structure contains pointers to functions in the Output Protection Manager (OPM) Interface, which is implemented by the display miniport driver.

Members

Size

The size, in bytes, of this structure.

Version

A positive integer that indicates the version number of the OPM interface that is implemented by the display miniport driver. The Version member must be set to DXGK_OPM_INTERFACE_VERSION_1, which is defined in Dispmprt.h.

Context

A pointer to a private context block. Context must be set to NULL.

InterfaceReference

A pointer to an interface reference function that is implemented by the display miniport driver. For more information about the operation of an interface reference function, see the Remarks section of the INTERFACE structure.

InterfaceDereference

A pointer to an interface dereference function that is implemented by the display miniport driver. For more information about the operation of an interface dereference function, see the Remarks section of the INTERFACE structure.

DxgkDdiOPMGetCertificateSize

A pointer to the display miniport driver's DxgkDdiOPMGetCertificateSize function.

DxgkDdiOPMGetCertificate

A pointer to the display miniport driver's DxgkDdiOPMGetCertificate function.

DxgkDdiOPMCreateProtectedOutput

A pointer to the display miniport driver's DxgkDdiOPMCreateProtectedOutput function.

DxgkDdiOPMGetRandomNumber

A pointer to the display miniport driver's DxgkDdiOPMGetRandomNumber function.

DxgkDdiOPMSetSigningKeyAndSequenceNumbers

A pointer to the display miniport driver's DxgkDdiOPMSetSigningKeyAndSequenceNumbers function.

DxgkDdiOPMGetInformation

A pointer to the display miniport driver's DxgkDdiOPMGetInformation function.

DxgkDdiOPMGetCOPPCompatibleInformation

A pointer to the display miniport driver's DxgkDdiOPMGetCOPPCompatibleInformation function.

DxgkDdiOPMConfigureProtectedOutput

A pointer to the display miniport driver's DxgkDdiOPMConfigureProtectedOutput function.

DxgkDdiOPMDestroyProtectedOutput

A pointer to the display miniport driver's DxgkDdiOPMDestroyProtectedOutput function.

Remarks

A kernel-mode component that must use the OPM interface initiates a call to the display miniport driver's DxgkDdiQueryInterface function to retrieve the interface.

For more information on how to use this structure with the OPM interface, see Retrieving the OPM DDI.
