ABSTRACT:
Hardware subsystems detect fault condition events in a computer system. The hardware determines, in response to each detected event, an appropriate corresponding behavior. A message is then communicated to the operating system identifying the desired responsive behavior. In response, the operating system executes appropriate preselected subroutines to cause the desired responsive behavior. New hardware, fault conditions, and behaviors may thereby be supported without necessitating corresponding modification and testing of the operating system software per se. Desired behavior of the operating system responsive to new hardware subsystems or system modifications are communicated to the operating system as behavior messages rather than events. The operating system is thereby not burdened with maintaining an appropriate behavioral responses corresponding to widely ranging and changing events associated with a plurality of different hardware systems supported by the same operating system.
