APPARATUS AND METHOD FOR VIRTUALIZATION OF INTERRUPT CONTROLLER IN A COMPUTER SYSTEM

摘要

PURPOSE: A virtualization apparatus of an interrupt controller in a computer system and a method thereof are provided to proceed the virtualization of the interrupt controller which the correction of the part related to the interrupt controller is unnecessary in OS and to transfer the hardware interrupt to the OS through VMM. CONSTITUTION: A computer hardware(200) comprises a hardware interrupt controller(302). A VMM(Virtual Machine Monitor)(210) offers virtual computer hardware environment between the computer hardware and two OS(Operating System)s (220), and virtualizes the hardware interrupt controller. The OS controls the computer hardware by using application programs. If CPU processes the access toward the hardware interrupt controller of the OS as exception operation, the VMM transfers the access toward the hardware interrupt controller to a virtual interrupt controller(312).
