Simple Peripheral Bus (SPB) Interface

A Windows Display Driver Model (WDDM) 1.2 and later display miniport driver can access bus resources on a system-on-a-chip (SoC) system by calling these Simple Peripheral Bus (SPB) functions:

To use these functions, first supply the Size and Version members of the DXGK_SPB_INTERFACE structure. Then call the DxgkCbQueryServices function with the ServicesType parameter set to a value of DxgkServicesFirmwareTable, and set the Interface parameter to the address (cast as PINTERFACE) of the DXGK_SPB_INTERFACE structure.

For more information on SPB architecture, see Simple Peripheral Buses and SPB Peripheral Device Driver Overview.
