The Kernel-Mode Driver Framework (KMDF) is a driver framework developed by Microsoft as a tool to aid driver developers create and maintain kernel mode device drivers for Windows 2000 [a] and later releases. It is one of the frameworks included in the Windows Driver Frameworks. [1]
In order to allow simpler creation of drivers for Winprinters, the Microsoft Universal Printer Driver was created. This allows printer vendors to write Generic Printer Description (GPD) "minidrivers", which describe the printer's capabilities and command set in plaintext, rather than having to do kernel mode driver development.
User-Mode Driver Framework v2, for writing user-mode drivers with syntactic parity to KMDF; WDF also includes a set of static verification tools for use by driver writers. These tools examine driver code for common errors and/or simulate the code of a driver in order to identify problems that are both difficult to detect and difficult to test for.
The Kernel-Mode Driver Framework (KMDF) model continues to allow development of kernel-mode device drivers but attempts to provide standard implementations of functions that are known to cause problems, including cancellation of I/O operations, power management, and plug-and-play device support.
Badly written device drivers can cause severe damage to a system (e.g., BSoD or data corruption) since all standard drivers have high privileges when accessing the kernel directly. The User-Mode Driver Framework insulates the kernel from the problems of direct driver access, instead providing a new class of driver with a dedicated application ...
The Linux kernel got the prerequisite for kernel-based mode setting by accepting Intel GEM in version 2.6.28, released in December 2008. [2] This will be [needs update] replaced by Tungstens Graphics TTM (Translation Table Maps) memory manager which supports the GEM API. [3]
These are being kept fairly stable, but there is no guarantee for stability. A kernel-internal API can be changed when such a need is indicated by new research or insights; all necessary modifications and testing have to be done by the author. The Linux kernel is a monolithic kernel, hence device drivers are kernel components.
The WDM framework was developed by Microsoft to simplify the communication between the operating system and drivers inside the kernel. In Windows operating systems, drivers are implemented as Dynamic Link Libraries.DLL or .SYS files. WDM compliant drivers must follow rules of design, initialisation, plug-and-play, power management and memory ...
