Abstract
A system and method is disclosed for the handling of interrupts by the disabled logical processors of an information handling system or computer system. An interrupt service routine is written to the read-only portion of system memory. Upon receipt of an interrupt, each disabled logical processor branches to the hard coded interrupt service routine. The interrupt service routine can be written to read only memory because the context, current instruction, and return state of the disabled logical processor are known, and the disabled logical processor will not need to write to system memory during the execution of the interrupt service routine. Following the handling of the interrupt by another logical processor of the computer system, each disabled logical processor returns to the halt state.
