 Abstract: This is a tiny driver that attaches to a PCI device and logs information
    about it. It doesn't alter the device in any way. It also supports a
    generic IOUserClient subclass that allows driver-specific client code to
    make various kinds of calls into the driver, and map shared memory
    or portions of hardware memory.
  Version: 1.1
