ABSTRACT:
An information handling system is provided which includes a dynamic interrupt router for balancing interrupt assignments among a plurality of devices requesting interrupt assignments. The system balances interrupt assignments among both fixed devices mounted on the processor board and interrupt assignments to devices situated in expansion slots. When the system is populated with a large number of devices relative to the number of available interrupts, improved interrupt sharing is desirably achieved by causing a device which generates a large number of interrupt requests to share a common interrupt with a device which generates a lower number of interrupts.
