Windows Display Driver Model (WDDM). It also supports new DXGI interfaces required for basic device management and creation. The WDDM specification requires at least Direct. ![]() D 9- capable video card and the display driver must implement the device driver interfaces for the Direct. D 9. Ex runtime in order to run legacy Direct. D applications; it may optionally implement runtime interfaces for Direct. D 1. 0/1. 0. 1 and higher. Features enabled by the WDDM. These include: Virtualized video memory. WDDM drivers allow video memory to be virtualized. In case the video memory available turns out to be insufficient to store all the video data and textures, currently unused data is moved out to system RAM or to the disk. When the swapped out data is needed, it is fetched back. Virtualization could be supported on previous driver models (such as the XP Driver Model) to some extent, but was the responsibility of the driver, instead of being handled at the runtime level. Scheduling. This differs from native threads on the CPU where one task cannot be interrupted and therefore can take longer than necessary and make the computer appear less responsive. A hybrid scheduling algorithm between native and light threads with cooperation between the threads would achieve seamless parallelism. It is important to note that scheduling is not a new concept but it was previously the responsibility of individual driver developers. WDDM attempts to unify the experience across different vendors by controlling the execution of GPU tasks. Cross- process sharing of Direct. D surfaces. WDDM allows Direct. D surfaces to be shared across processes. Sharing textures between processes before WDDM was difficult, as it would have required copying the data from video memory to system memory and then back to video memory for the new device. Enhanced fault- tolerance. With a WDDM driver, all hardware faults cause the driver to be reset and the user will be notified by a popup; this unifies the behavior across vendors. Previous drivers were fully implemented in kernel mode, whereas WDDM is implemented partly in user mode. If the user mode area fails with an unrecoverable error, it will, at the most, cause the application to quit unexpectedly instead of producing a blue screen error as it would in previous driver models. WDDM also allows the graphics hardware to be reset and users to update drivers without requiring a reboot. However, according to Microsoft as of 2. Windows Vista used the XDDM. It also requires some other hardware features; consequently some SM 2. Intel GMA 9. 00 fails the WDDM certification. If a multi- monitor system has more than one graphics adapter powering the monitors, both the adaptors must use the same WDDM driver. If more than one driver is used, Windows will disable one of them. Since the desktop and application windows managed by DWM are Direct. D applications, the number of open windows directly affects the amount of video memory required. Because there is no limit on the number of open windows, the video memory available may prove insufficient, necessitating virtualization. As the window contents that DWM composes into the final desktop are generated by different processes, cross- process surface sharing is necessary. Also, because there can be other Direct. X applications running alongside DWM on the DWM- managed desktop, they must be able to access the GPU in a shared manner, necessitating scheduling. Though this is true for Microsoft's implementation of a composited desktop under Windows Vista, on the other hand, a composited desktop need not theoretically require a new display driver model to work as expected. Successful implementations of composited desktops were done before Windows Vista on other platforms such as Quartz, Compiz, Window. FX. The approach Microsoft attempted was to try to make sure WDDM was a unified experience across different GPUs from multiple vendors by standardizing their features and performance. The software features missing from other driver models could be made immaterial by extensions or if a less restrictive or simply different driver model was in place. History. New features include. Windows 8, and Direct. D 1. 1 Video supports YUV 4: 4: 4/4: 2: 2/4: 2: 0/4: 1: 1 video formats with 8, 1. Driver feature additions include wireless displays (Miracast), YUV format ranges, cross- adapter resources and GPU engine enumeration capabilities. WDDM 2. 0. The new API will do away with automatic resource- management and pipeline- management tasks and allow developers to take full low- level control of adapter memory and rendering states.
