Abstract
Performance in object-oriented systems may be improved by allowing multiple concurrent hardware control and diagnostic operations to run concurrently on the system while preventing race conditions, state/data corruption, and hangs due to deadlock conditions. Deadlock prevention rules may be employed to grant or deny request for hardware operation locks, hardware communication locks, and/or data locks.
