Windows Driver Frameworks (WDF, formerly Windows Driver Foundation), is a set of Microsoft tools and libraries that aid in the creation of device drivers for Windows 2000 and later versions of Windows.
WDM is generally not backward-compatible, that is, a WDM driver is not guaranteed to run on any older version of Windows. For example, Windows XP can use a driver written for Windows 2000 but will not make use of any of the new WDM features that were introduced in Windows XP. However, a driver written for Windows XP may or may not load on ...
In general, since more features like power management and plug and play are handled by the KMDF framework, a KMDF driver is less complicated and has less code than an equivalent WDM driver. KMDF is object-based and built on top of WDM. It provides an object-based perspective to WDM, following the architectural mandate of its superset, WDF.
WMI extensions for WDM offer a set of Windows device driver interfaces for instrumenting data within the driver models native to Windows, so OEMs and IHVs can easily extend the instrumented data set and add value to a hardware/software solution. The WMI Driver Extensions, however, are not supported by Windows Vista and later operating systems. [11]
The USB manager is composed of two parts, first a tiny USBD implementation (USB stack) then a simple Windows Driver Model (WDM) USB driver that is itself composed of two parts: The front part will receive calls from the NDISwrapper USB stack (in fact from calls coming from the original Windows driver that were normally intended to go to the ...
VxD is the device driver model used in Microsoft Windows/386 2.x, the 386 enhanced mode of Windows 3.x, Windows 9x, and to some extent also by the Novell DOS 7, OpenDOS 7.01, and DR-DOS 7.02 (and higher) multitasker (TASKMGR). [1]
The Multimedia Extensions were released to Original Equipment Manufacturers (OEMs), mainly CD-ROM drive and sound card manufacturers, and added basic multimedia support for audio input and output and a CD audio player application to Windows 3.0. The Multimedia Extensions' new features were not available in Windows 3.0 real mode, only in ...
During the Windows 2000, XP, 2003 timeframe there was an old tool Hardware Compatibility Test (HCT) to certify devices.When Windows Vista was released the tool was replaced by Driver Test Manager (DTM) which can certify drivers for all then-supported platforms.
