virt: acrn: Introduce irqfd
irqfd is a mechanism to inject a specific interrupt to a User VM using a
decoupled eventfd mechanism.
Vhost is a kernel-level virtio server which uses eventfd for interrupt
injection. To support vhost on ACRN, irqfd is introduced in HSM.
HSM provides ioctls to associate a virtual Message Signaled Interrupt
(MSI) with an eventfd. The corresponding virtual MSI will be injected
into a User VM once the eventfd got signal.
