 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
