virtio-input is basically evdev-events-over-virtio, so this driver isn't much more than reading configuration from config space and forwarding incoming events to the linux input layer.

For multi-touch devices the frontend needs to initialize the correct number of slots for touch tracking. Hardware drivers do this by calling input_mt_init_slots() on initialization. For virtio_input the function must be called when the backend sends ABS_MT_SLOT.
