    Debug output is filtered at two levels: A global level and a component
    specific level.

    Each debug output request specifies a component id and a filter level
    or mask. These variables are used to access the debug print filter
    database maintained by the system. The component id selects a 32-bit
    mask value and the level either specified a bit within that mask or is
    as mask value itself.

    If any of the bits specified by the level or mask are set in either the
    component mask or the global mask, then the debug output is permitted.
    Otherwise, the debug output is filtered and not printed.

    The component mask for filtering the debug output of this component is
    Kd_NTOSPNP_Mask and may be set via the registry or the kernel debugger.

    The global mask for filtering the debug output of all components is
    Kd_WIN2000_Mask and may be set via the registry or the kernel debugger.

    The registry key for setting the mask value for this component is:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\
        Debug Print Filter\NTOSPNP

    The key "Debug Print Filter" may have to be created in order to create
    the component key.

    Pnp is divided into the following sub-components for debug spew.
        1. LOADUNLOAD: AddDevice, UnloadDriver etc
        2. RESOURCE: Allocation, rebalance etc
        3. ENUMERATION: Starts, enumerations etc
        4. IOAPI: IO APIs etc
        5. IOEVENT: IO events etc
        6. MAPPER: Firmware mapper etc
        7. PNPBIOS: PnP BIOS etc
    Each sub-component gets 5 debug levels. The error level for each component
    maps to the default error level.
