Summary:An interrupt steering architecture that enables an intelligent peripheral device to process interrupts from PCI devices associated with a PCI bus is disclosed. The interrupt steering architecture enables the PCI interrupt signals to be steered to either a host CPU or to an intelligent peripheral device. The interrupt steering architecture is wholly compliant with the PCI bus specification and does not utilize additional sideband signals. The interrupt steering architecture is under user control and can be set by the user at system initialization or reset.
