Abstract
This application provides a virtualized device, and an interrupt processing method running on the virtualized device. The method includes: performing, by a processor, the following operations in a guest mode: receiving, by the processor, an interrupt request from hardware; determining, by the processor, a processing entity of the received interrupt request based on a correspondence between the interrupt request and the processing entity; and when the processing entity of the received interrupt request includes the virtual processor currently running on the processor, determining, by the processor based on a correspondence between the interrupt request and an interrupt service routine, the interrupt service routine corresponding to the received interrupt request, and invoking the interrupt service routine to process the interrupt request. In this manner, trap-in and trap-out of a processor can be avoided for an application interrupt request, thereby reducing a processing delay of the application interrupt request.
