Developing drivers with wdf

 · To improve driver serviceability and help to prevent compatibility problems, WDF provides versioning and support for side-by-side operation of different framework major versions. Each release of the framework has a major and minor version number. A WDF driver always uses the major version for which it was built and tested. Use the Windows Driver Foundation to develop kernel-mode or user-mode drivers; Create drivers that support Plug and Play and power management—with minimal code; Implement robust I/O handling code; Effectively manage synchronization and concurrency in driver code; Develop user-mode drivers for protocol-based and serial-bus-based devicesCited by:  · The core precept of WDF driver security is that every driver must work to prevent unauthorized access to devices, files, and data. WDF is designed to contribute to driver security by providing safe defaults and extensive parameter validation.

The WDF object model defines a set of objects that represent common driver constructs such as devices, memory, queues, I/O requests, and the driver itself. Framework objects have well-defined life cycles and contracts, and a WDF driver interacts with them through well-defined interfaces. The Developing Drivers with Windows Driver Foundation book is also available to help you learn the concepts and fundamentals of Windows Driver Frameworks (WDF). This book introduces Windows drivers and basic kernel-mode programming, and then describes the WDF architecture and programming model. It provides a practical, sample-oriented guide to using the frameworks to develop Windows drivers. Orwick, Penny and Guy Smith. Developing Drivers with Windows Driver Foundation. Redmond, WA. The WDF driver model defines an object-oriented, event-driven environment for both kernel-mode (KMDF) and user-mode (UMDF) drivers. Driver code manages device-specific features, and a Microsoft-supplied framework calls the WDF driver to respond to events that affect the operation of its device. This chapter introduces fundamental concepts for the design and implementation of WDF for UMDF and KMDF drivers.

The Windows Driver Foundation (WDF) is a wrapper around Microsoft Windows Driver It abstracts away much of the complexity of writing Windows drivers. University shows that device drivers have error rates up to WDF provides a new driver development method by repackaging WDM. The Developing Drivers with Windows Driver Foundation book is also available to help you learn the concepts and fundamentals of Windows.
