  • Method and apparatus for interrupting a processor by a PCI peripheral across an hierarchy of PCI buses
    Patent number: 5771387
    Abstract: A number of remote I/O ICUs, enhanced PCI--PCI bridges, and an ICC bus interface unit are distributively provided to a computer system having a processor and an hierarchy of PCI buses for facilitating PCI agents coupled to the lower level PCI buses to interrupt the processor during operation. The remote I/O ICUs, the enhanced functions of the PCI--PCI bridges, and the ICC bus interface unit advantageously leverage the PCI--PCI bridges' conventional ability in handling PCI type 1 configuration write transactions, to facilitate interrupt delivery and end of interrupt notification, by employing two specially defined PCI type 1 configuration write transactions, one for interrupt messages and another for end-of-interrupt (EOI) messages.
