The PFND3DDDI_QUERYDLISTFORAPPLICATION1 function queries a dList for an application.
unnamedParam1 [out]If TRUE, the application should be run on the discrete GPU. Otherwise, the application should run on the integrated GPU.
unnamedParam2 [in]A handle to the graphics adapter object. This handle is passed to the pfnEscapeCb callback function pointed to by unnamedParam3.
unnamedParam3 [in]Pointer to a pfnEscapeCb callback function that shares info with the display miniport driver.
Returns S_OK, or an appropriate error result if the operation is not successful.
Starting with WDDM 2.9, drivers must support PFND3DDDI_QUERYDLISTFORAPPLICATION2 instead of PFND3DDDI_QUERYDLISTFORAPPLICATION1.
In WDDM versions prior to WDDM 2.9, PFND3DDDI_QUERYDLISTFORAPPLICATION1 is called by the user-mode graphics runtime (DXGI) during Microsoft Direct3D initialization on a hybrid system to determine which GPU an application should run on. A dList is a list of applications that need cross-adapter shared surfaces for high-performance rendering on the discrete GPU.
For more information on how to call this function and set up the DLL that exports it, see Hybrid system DDI.
