HYBRID VIRTUALIZATION SCHEME FOR INTERRUPT CONTROLLER

摘要

The purpose of the present invention is to reduce interrupt latency by a hybrid virtualization method. To achieve the purpose, provided is the hybrid virtualization method including: a step of allowing a virtual machine manager (VMM) to operate, wherein the VWM is to enable a program run in a host and a program run in a guest to be used at the same time; a step of allowing the VMM to provide a virtual interrupt configuration register to the guest; and a step of reducing interrupt latency by selectively using full virtualization using a trap-and-emulate method and partial virtualization enabling the guest to directly access the interrupt control register.
