INTERRUPT PROCESSING METHOD, IOAPIC AND COMPUTER SYSTEM

摘要

An interrupt processing method, an IOAPIC and a computer system, which relate to the technical field of computers and are used for an IOAPIC to accurately forward an interrupt request. The IOAPIC forwards the interrupt request according to a pre-set mapping relationship between an IOAPIC physical pin and a processor or a processor cluster, and can avoid an IOAPIC forwarding interrupt error to some extent. The method comprises: an IOAPIC receiving a first interrupt request sent by a first peripheral device (101); determining a first load operating system corresponding to the first peripheral device according to a correlation between each load operating system recorded by a management operating system and a hardware resource of each load operating system (102); and sending the first interrupt request to a processor or a processor cluster of the first load operating system by means of a physical pin corresponding to the processor or the processor cluster of the first load operating system according to a pre-set mapping relationship between an IOAPIC physical pin and the processor or the processor cluster (103).
