Method, system, and program for improved interrupt processing

A method for processing an interrupt, comprising:

• receiving a new interrupt;
• determining whether a number of previously claimed consecutive interrupts that were claimed without determining whether an associated interrupting device generated each of the consecutive interrupts meets a first threshold;
• and
• if the first threshold is not met, determining whether to claim the new interrupt without determining whether an associated interrupting device generated the new interrupt.

A system for processing an interrupt, comprising:

• a processor;
• memory coupled to the processor;
• and
• at least one program executed by the processor in the memory to cause the processor to perform:
• (i) receiving a new interrupt;
• (ii) determining whether a previous interrupt was correctly claimed;
• and
• (iii) if the previous interrupt was correctly claimed, determining whether to claim the new interrupt without determining whether an associated interrupting device generated the new interrupt.
