[vfio-users] [PATCH v2 1/3] input: add qemu_input_qcode_to_linux + qemu_input_linux_to_qcode

[Jonathan Scruggs]

Oh. I just changed /dev/input/eventx (replace x with correct number for my
devices) to permissions of 666 and it worked. I guess I had to change the
conf file and change the permissions. Is there a way to make the devices
work with qemu? The permission user is root and group of input for all the
eventx devices. Do I need a udev script or is there a qemu user that can be
added to the group of input?

Thanks
