[Qemu-devel] [PATCH qemu 4/6] virtio-input: emulated devices |
Date: |
Thu, 10 Apr 2014 11:07:52 +0200 |
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
