Current IO emulation is synchronous. The user VM need to wait for the completion of the the I/O request before return. But Virtio Spec introduces introduces asynchronous IO with a new register in MMIO/PIO space named NOTIFY, to be used for FE driver to notify BE driver, ACRN hypervisor can emulate this register by sending a notification to vCPU in Service VM side. This way, FE side can resume to work without waiting for the full completion of BE side response.
