A Minimal KMDF Driver: The Simple Toaster

The Simple Toaster sample provided in toaster\func\simple is a minimal, software-only function driver. It creates a driver object, a device object, a device interface, and single I/O queue. The driver handles read, write, and device I/O control requests that are targeted at its device.

The minimal driver includes the following functions:

  • A DriverEntry routine, which creates the driver object
  • An EvtDriverDeviceAdd event callback, which creates the device object, a device interface, and a default I/O queue
  • I/O callback functions for read, write, and device I/O control requests

The driver does not manage any physical hardware, so no code to support Plug and Play or power management is required; the driver uses the WDF defaults.
