The APU GIC v2 interrupt virtualization is a mechanism to aid interrupt handling, with native distinction of interrupt destined to secure-monitor, hypervisors, currently active guest operating systems, or non-currently-active guest operating systems. This reduces the complexity of handling interrupts using software emulation techniques in the hypervisor.
