ABSTRACT:
Method and system for managing interrupts originating from multiple sources is provided. The method includes assigning interrupt sources to a group; notifying an adapter of interrupt groups; identifying each interrupt group; writing a first interrupt to an interrupt module, where the interrupt occurs from a first source of the multiple sources; monitoring for a second interrupt; suspending the second interrupt until the first interrupt is processed, if the second interrupt is requested from the first source; and processing the second interrupt, if the second interrupt occurs from a source other than the first source.
