Interrupt management method and device, electronic equipment and computer storage medium

Abstract

The embodiment of the invention provides an interrupt management method and device, electronic equipment and a computer storage medium, and relates to the field of interrupt processing. The method comprises the following steps: receiving a to-be-processed target interrupt, and obtaining a target interrupt number of the to-be-processed target interrupt; if it is determined that the target interrupt number is pre-configured for the target virtual machine, judging whether the target interrupt number is larger than a preset threshold value or not; if it is determined that the target interrupt number is larger than a preset threshold value, judging whether the target virtual machine initializes the target interrupt number in advance or not; and if it is determined that the target virtual machine has initialized the target interrupt number in advance, forwarding the target interrupt to the target virtual machine. Through multiple times of judgment, the security in the interrupt processing process is ensured, each virtual machine can only process the interrupt configured by the virtual machine, fine-grained management is carried out on the interrupt, the interrupt processing efficiency is improved, and meanwhile, the security of the electronic equipment is also improved.

Description

technical field [0001] The present application relates to the technical field of interrupt processing, and in particular, the present application relates to an interrupt management method, device, electronic equipment, and computer storage medium. Background technique [0002] The virtualization environment of computers, mobile terminals or similar electronic devices can support the operation of multiple virtual machines, and each virtual machine can run the entire operating system, but there is usually only one set of hardware resources for electronic devices, and multiple virtual machines share a set of hardware Resources, the environment in which each virtual machine runs is not on real hardware resources, but in virtual memory on top of hardware resources, that is, in a virtualized environment. The interrupts involved are very important, and its virtualization is also very critical. [0003] In the prior art, all interrupts are generally controlled by the virtual machine...

AI Technical Summary

Problems solved by technology

[0004] The virtual machine alone controls the initialization and processing of interrupts, which is not conducive to the security of electronic devices. If the virtual machine is illegally usurped by malware, the malware can access almost all resources in the electronic device, causing various security problems
