The First Authoritative advisor to Writing strong, High-Performance home windows 7 machine Drivers
Windows 7 equipment driving force brings jointly the entire details skilled programmers have to construct highly trustworthy, high-performance home windows 7 drivers. the world over well known driving force improvement professional Ronald D. Reeves indicates the best way to utilize Microsoft’s strong new instruments and types; keep time and cash; and successfully convey good, strong drivers.
Drawing on his unsurpassed adventure as either a driving force developer and teacher, Reeves demystifies Kernel and person Mode driving force improvement, home windows motive force starting place (WDF) structure, driving force debugging, and lots of different key subject matters. all through, he presents top practices for all elements of the driving force improvement approach, illuminating his insights with confirmed pattern code. how to
Use WDF to minimize improvement time, enhance method balance, and increase serviceability
Take complete benefit of either the person Mode motive force Framework (UMDF) and the Kernel Mode driving force Framework (KMDF)
Implement top practices for designing, constructing, and debugging either consumer Mode and Kernel Mode Drivers
Manage I/O requests and queues, self-managed I/O, synchronization, locks, plug-and-play, energy administration, gadget enumeration, and more
Develop UMDF drivers with COM
Secure Kernel Mode Drivers with secure defaults, parameter validation, counted UNICODE strings, and secure equipment naming techniques
Program and troubleshoot WMI help in Kernel Mode Drivers
Utilize complex a number of I/O queuing techniques
Whether you’re growing home windows 7 drivers for laboratory apparatus, communications undefined, or the other equipment or know-how, this publication might help you construct construction code extra fast and get to industry sooner!

Additional info for Windows 7 device driver
Occasionally, however, a driver might require information from a different driver before it can complete a request. To obtain this information, the driver creates an object to represent the remote I/O target, creates a WDF request object, and then calls methods on the I/O target to send the request. 5 Plug and Play and Power Management Requests When a Plug and Play or power request arrives, the framework determines whether any Plug and Play or power management state changes are required to satisfy the request.
Multiple WDF drivers can use a single WDF library. They can also run side by side using different major versions of the framework. Wow! Com> PA R T I I USER MODE DRIVERS Wow!

The User Mode Driver Framework (UMDF) is designed to support protocol device classes such as cameras and portable music players.
2 User Mode Objects UMDF objects are based on the component object model (COM). The UMDF uses a small subset of COM for query-interface and reference counting features. 2 Commonly Used KMDF Object Types Object Type Name Usage WDFDRIVER WDFDEVICE WDFQUEUE WDFINTERRUPT WDFREQUEST WDFMEMORY WDFDMANENABLE Represents the driver object Represents a device object Represents a queue of I/O request Represents an interrupt resource Describes an I/O request Describes a buffer for an I/O request Describes the characteristic of all DMA transfers for a device Manages operations for an individual DMA request Represents the driver that is the target of an I/O request WDFDMATRANSACTION WDFIOTARGET Wow!
