To: qemu-devel; +Cc: Gerd Hoffmann, mst
This patch adds virtio-input support to qemu. It brings a abstract
base class providing core support, other classes can build on it to
actually implement input devices.
virtio-input basically sends linux input layer events (evdev) over
virtio.

From: Gerd Hoffmann @ 2015-03-20 14:07 UTC (permalink / raw)
To: qemu-devel; +Cc: Gerd Hoffmann, mst
This patch adds the virtio-input-hid base class and
virtio-{keyboard,mouse,tablet} subclasses building on the base class.
They are hooked up to the qemu input core and deliver input events
to the guest like all other hid devices (ps/2 kbd, usb tablet, ...).
Using them is as simple as adding "-device virtio-tablet-pci" to your
command line. If you want add multiple devices but don't want waste
a pci slot for each you can compose a multifunction device this way:
qemu -device virtio-keyboard-pci,addr=0d.0,multifunction=on \
-device virtio-tablet-pci,addr=0d.1,multifunction=on

This allows to assign host input devices to the guest:
qemu -device virto-input-host-pci,evdev=/dev/input/event<nr>
The guest gets exclusive access to the input device, so be careful
with assigning the keyboard if you have only one connected to your
machine.
