Windows Driver Frameworks
The Windows Driver Frameworks (WDF), formerly the Windows Driver Foundation, are a set of Microsoft tools and libraries that aid in the creation of device drivers for Windows 2000 and later versions of Windows. It complements the Windows Driver Model, abstracting away much of the boilerplate complexity with writing Windows drivers.
The WDF consists of the Kernel-Mode Driver Framework (KMDF) and User-Mode Driver Framework (UMDF). These individual frameworks provide a new object-oriented programming model for Windows driver development. The primary goals of the WDF are conceptual scalability and reduced duplication, enabling developers to apply the same concepts across different driver types and reducing the code overhead required for drivers. This differs markedly from the Windows Driver Model (WDM) which requires driver developers to be fully familiar with many complex technical details to write a basic driver.
Part of the key to achieving conceptual scalability is that KMDF and UMDF use an "opt-in" model. This model allows the developer to extend and override the default behavior of a canonical "good driver". In contrast, the Windows Driver Model depends on the driver writer to implement all aspects of the driver's behavior.
There are three types of WDF drivers:
- The Kernel-Mode Driver Framework, for writing standard kernel-mode device drivers.
- The User-Mode Driver Framework v1, for writing user-mode drivers using a C++ COM based API.
- The 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 Static Driver Verifier (SDV) is capable of performing very deep validation of code paths across functions and even through calls into WDM. SDV can find driver problems that span multiple function calls and even multiple operations. SDV is designed to be run when the driver is nearing completion. SDV analyzes only C files. C++ is not supported.
PREFast for Drivers (PFD) performs rather shallow analysis of driver operations. PFD can check for buffer overruns and other common programming errors likewise a number of driver specific problems. Because its scope of operation is within a single function, PFD's run time is much shorter than SDV. Therefore, PFD can be used throughout the driver development process. PREFast scans each function as an isolated unit. It does not do inter-procedural analysis.
