It facilitates the creation of drivers for certain classes of devices.Badly written device drivers can cause severe damage to a system (e.g., BSoD and data corruption) since all standard drivers have high privileges when accessing the kernel directly.
Microsoft Kernel Mode Framework Driver Framework InsulatesThe 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 programming interface at the user level of interrupts and memory management.![]()
Microsoft Kernel Mode Framework Drivers For CertainCode-named Crescent, it was designed to support the Media Transfer Protocol driver, and no public interfaces or documentation were provided for it. Later, Microsoft decided to turn UMDF into a device driver development platform. However, UMDF does not use COM for loading, unloading, or controlling concurrency; it only uses COM as a programming pattern, for example exploiting COMs IUnknown interface. At startup, UMDF calls DllGetClassObject to get a pointer to an IClassFactory interface in the driver and then uses the CreateInstance method of the IClassFactory interface to create an instance of the driver callback object. The driver provides a set of callbacks via the IDriverEntry COM interface, which is the main entry point for driver customization. Peter Wieland: User Mode Driver Framework. Channel 9. Microsoft.
