This section provides reference pages for Output Protection Manager (OPM) interface functions, which are implemented by some display miniport drivers.
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. Pointers to the OPM interface functions are returned in a DXGK_OPM_INTERFACE structure that the Interface member of the QUERY_INTERFACE structure points to. This QUERY_INTERFACE is pointed to by the QueryInterface parameter in the DxgkDdiQueryInterface call.
For more information about how a display miniport driver can support OPM, see Supporting Output Protection Manager.
