Problems solved by technology

For example: when the IOAPIC is maliciously modified, the interrupt corresponding to the load operating system 1 is sent to the processor of the load operating system 2, which will cause system confusion and operating system 1 cannot normally perform operations based on the interrupt

Abstract

The invention provides an interrupt processing method, an IOAPIC (Input / Output Advanced Programmable Interrupt Controller) and a computer system, relates to the technical field of the computer and is used for the IOAPIC to accurately forward an interrupt request. According to a preset mapping relationship between an IOAPIC physical pin and a processor or a processor cluster, the IOAPIC forwards the interrupt request, and an IOAPIC interrupt forwarding error can be avoided to a certain degree. The interrupt processing method comprises the following steps of: the IOAPIC receives a first interrupt request sent from first peripheral equipment; according to a corresponding relationship, which is recorded by a management operating system, between each load operating system and the hardware resource of each load operating system, the first load operating system corresponding to the first peripheral equipment is determined; and according to the preset mapping relationship between the IOAPIC physical pin and the processor or the processor cluster, through the physical pin corresponding to the processor or the processor cluster of the first load operating system, the first interrupt request is sent to the processor or the processor cluster of the first load operating system.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to an interrupt processing method, an IOAPIC and a computer system. Background technique [0002] At present, IOAPIC (Input / Output Advanced Programmable Interrupt Controller, input / output advanced programmable interrupt controller), LAPIC (Local Advanced Programmable Interrupt Controller, local advanced programmable interrupt controller) can realize interrupt control. [0003] At present, for a system with a single core (that is, there is only one operating system, which may include multiple CPUs), the IOAPIC can forward the interrupt to any CPU after receiving the interrupt. With the development of the computer technology field, a multi-core (multi-operating system) scenario is derived, including a management operating system and at least one load operating system. The management operating system configures at least one peripheral device and at least one processor for each load ...
