This application claims priority to and the benefit of Korean Patent Application No. 10-2019-0155329, filed on Nov. 28, 2019, the disclosure of which is incorporated herein by reference in its entirety.
Various embodiments disclosed herein relate to an interrupt configuration control technique.
Computer manufacturers want to maximize market share by allowing a large number of applications to run on central processing units (CPUs) provided by the computer manufacturers. In order to increase the number of operating systems and application programs executable in a computer system, an emulator program for supporting a host computer (a computer with a host CPU) to emulate (or virtualize) a guest computer (a computer with a guest CPU of a different family from that of the host CPU) has been disclosed. An emulator program (a virtualizer) creates an emulation environment and performs a function of interchange between the hardware architecture of a host computer and software executed in an emulation environment. A virtualizer (e.g., a virtual machine monitor (VMM) and a hypervisor) virtualizes guest hardware using software to create a virtual machine (hereinafter referred to as a partition) and makes use of the virtual machine to rely on a host operating system for functions required by a guest operating system.
