adds support for reading input events directly from linux
evdev devices and forward them to the guest. Unlike
which simply passes on all events to the guest without
looking at them
this will interpret the events and feed them into the qemu
Therefore this is limited to what the qemu input subsystem
emulated input devices are able to handle. Also there is no
absolute coordinates (tablet/touchscreen). So we are
talking here about
basic mouse and keyboard support.
The advantage is that it'll work without virtio-input
drivers in the
guest, the events are delivered to the usual ps/2 or usb
(depending on what the machine happens to have). And for
qemu is able to switch the keyboard between guest and host
The hotkey is hard-coded for now (both control keys),
guest owns the keyboard.
Probably most useful when assigning vga devices with vfio
and using a
physical monitor instead of vnc/spice/gtk as guest display.
Usage: Add '-input-linux /dev/input/event<nr>' to the
line. Note that udev has rules which populate
with static names, which might be more convinient to use.
