The DXGK_BRIGHTNESS_INTERFACE structure contains pointers to the kernel-mode display driver's (KMD) functions for Version 1 of the Panel Brightness Control Interface.
Size[in] The size, in bytes, of this structure.
Version[in] The version number of the brightness interface. Must be DXGK_BRIGHTNESS_INTERFACE_VERSION_1 for this structure. Version number constants are defined in Dispmprt.h.
Context[out] A pointer to a private context block.
InterfaceReference[out] A pointer to an interface reference function that is implemented by the KMD.
InterfaceDereference[out] A pointer to an interface dereference function that is implemented by the KMD.
GetPossibleBrightness[out] A pointer to the KMD's DxgkDdiGetPossibleBrightness function.
SetBrightness[out] A pointer to the KMD's DxgkDdiSetBrightness function.
GetBrightness[out] A pointer to the KMD's DxgkDdiGetBrightness function.
A kernel-mode component such as Dxgkrnl that must use the brightness interface initiates a call to the KMD's DxgkDdiQueryInterface function to retrieve the interface and passes a GUID_DEVINTERFACE_BRIGHTNESS in the InterfaceType member of the QUERY_INTERFACE structure that the QueryInterface parameter points to.
