Name Registry introduces the concept of the Name Registry. The Registry interface provides new mechanisms for drivers to expose information. Any data that might be of use to a configuration or debugging utility may be installed in the Registry and is directly available to the configuration application through the Registry programming interface.
Only a small set of Registry services are available at hardware or secondary interrupt level. The set of services available at nontask level are gets and sets of properties associated with a single device entry. For further information, see Service Limitations.
