Defines how shaders access resources (textures, buffers, constants) in a more flexible and performance-oriented way.
To use WDDM 2.0 driver, your system must meet the following requirements:
: DxgkDdiAddDevice is called first. It must allocate a context structure. DxgkDdiStartDevice is where the OS passes resources (like PCIe memory ranges) and you report how many "heads" (monitors) your card supports.
Interface->Size = sizeof(DXGKRNL_INTERFACE); Interface->Version = DXGKRNL_INTERFACE_VERSION; wddm 2.0 driver
WDDM 2.0 (Windows Display Driver Model 2.0) is a graphics driver model developed by Microsoft for Windows operating systems. It is a significant update to the original WDDM 1.0, which was introduced with Windows Vista. WDDM 2.0 provides a more efficient and secure way for graphics drivers to interact with the Windows operating system, enabling improved performance, power management, and features.
However, I can provide you with a . This skeleton demonstrates the necessary DriverEntry, the specific WDDM 2.0 DDI (Device Driver Interface) initialization, and the Plug and Play (PnP) dispatch routines required for the Windows operating system to recognize and load the driver.
: The functions DxgkDdiPresent , DxgkDdiRender , and DxgkDdiCreateAllocation are missing implementation here. In a real driver, these are the most complex parts, handling memory allocation and rendering commands. This skeleton provides the lifecycle management (Load/Unload/Start/Stop), which is the foundation of a driver. DxgkDdiStartDevice is where the OS passes resources (like
// DxgkDdiRemoveDevice: Cleanup context. NTSTATUS DxgkDdiRemoveDevice( IN_CONST PVOID MiniportDeviceContext )
return STATUS_SUCCESS;
The WDDM 2.0 driver offers several benefits to users, including: WDDM 2
Enhanced protected content playback for 4K and HDR streaming services.
