This allows decoupling input from the wayland socket while using a standard virtio device for it. The proposed virtio input spec can be found at https://www.kraxel.org/virtio/virtio-v1.0-cs03-virtio-input.pdf, it has already been implemented in qemu and (guest) kernel support exists since version 4.1. This change adds the following options to crosvm: --evdev: Grabs a host device and passes it through to the guest --<device>: Creates a default configuration for <device>, receives the input events from a unix socket. <device> can be 'keyboard', 'mouse' or 'trackpad'.
