Programming the microsoft windows driver model source code




















The installation of the driver is controlled by an. INF extension file. The installation of the driver changes the system registry entries with the new driver information. An INF file is a simple text file divided into sections, with each section designated by an identifier within closed braces [ ].

Some section names are required, while others are driver-specific. Entries under each section control some installation action, or they link to other sections. The order of the sections in this file is not important and a section continues until another section started or end of file is encountered. After the INF file is created, it must be processed to make the things working. Manual or automatic installation can be done with the INF file. By opening the INF in a windows explorer and selecting an install option after right clicking the file, starts the installation process or in a Plug and Play environment, installation can be started by insertion or removal of the device.

A segment of the INF files looks like the one given below. Sign in Email. Forgot your password? Search within: Articles Quick Answers Messages. Tagged as C. Stats Windows Device Drivers.

Structure of the WDM driver A driver is a collection of functions that operating system calls to perform various operations that is related to the hardware.

The figure below shows some of the operations Some of the functions above DriverEntry , AddDevice and some of the Dispatch routines are generally present in every device driver. The steps an operating system generally follows while calling functions in device driver are as follows When a device is plugged into system, the system loads the driver in virtual memory and calls the DriverEntry routine.

This routine then performs some operations and returns. The PnP manager then calls the AddDevice function and returns. An application open a handle to the device and the system sends another IRP then dispatch routine performs some work and returns. Application then tries to read data and the system sends you and IRP and dispatch routine puts that IRP in queue and returns.

Your interrupt routine does a little bit of work, schedule a DPC and returns. Your DPC routine runs and it removes the IRP scheduled in queue in above step and programs the hardware to read the data and then returns. System makes more calls to the driver and finally when the user unplugs the device, the PnP manager sends the IRPs, which you process and return.

The OS then calls the DriverUnload routine and that do some work and returns. Layering of driver and device objects are shown in figure below If an IRP is generated then the Upper filter will first get it before the function driver. PDO: It stands for physical device object and the bus driver use this object to represent the connection between device and bus. FDO: It stands for function device object and the function driver uses it to manage functionality of devices.

FiDO: It stands for filter device object and used by filter driver to store the information it needs to keep about the hardware and filtering activities.

Stacks can help you understand the flow of information to and from a driver and how different parts of the driver communicate internally.

Kernel-Mode Driver Components describes which routines you must implement to have a functional driver and which routines are optional. A device driver is a set of software code that must integrate into the operating system. To complete this integration, you must write a set of handler routines in your driver that process calls from the operating system.

The host driver and the device firmware. This book only covers the host driver. It's the best book out there for writing drivers though. And another question is? Or, how the host PC, firmware can work together?
