System Firmware Table Interface
The System Firmware Table interface contains functions that user-mode display drivers can use to read and enumerate the system firmware table. These functions are supplied by the Microsoft DirectX graphics kernel subsystem and can be called by WDDM 1.2 and later user-mode display drivers.
This section contains reference pages for these functions, which are implemented by the operating system and called by Windows Display Driver Model (WDDM) 1.2 and later display miniport drivers:
The display miniport driver must fill in pointers to these functions in the DXGK_FIRMWARE_TABLE_INTERFACE structure.
