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.
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]
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 ...
An oversimplification of how a kernel connects application software to the hardware of a computer. A kernel is a computer program at the core of a computer's operating system that always has complete control over everything in the system. The kernel is also responsible for preventing and mitigating conflicts between different processes. [1]
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.
To solve this problem, the kernel is designed to be extensible, and may accept an extra module called a device driver which runs in kernel space and can directly address the device. An ioctl interface is a single system call by which userspace may communicate with device drivers.
This system is, in turn, based on a model where drivers are expected to periodically "block" while they wait for tasks to complete. For instance, a printer driver might send a line of text to a line printer and then have nothing to do until the printer completes printing that line. In this case, the driver indicates that it was blocked, and the ...
Although drivers for most hardware are contained in other files, commonly of file type .sys, a few core drivers are compiled into hal.dll. Kernel mode device drivers for devices on buses such as PCI and PCI Express directly call routines in the HAL to access I/O ports and registers of their devices. The drivers use HAL routines because ...
