[Qemu-devel] How to pass intercepted mouse move x and y from host to a virtual machine running in Qemu

[Alexander Syvak]

Hi, guys!

There exists a manually written virtual USB device registered as Qemu type.

It reads 5 bytes

- x and y of a mouse move, x and y of scrolling, and buttons state -

from mouse.fifo but there is no code in the implementation file which would
actually parse those bytes.

First where does Qemu actually parse those bytes?

And the most important - can I actually pass double value for a mouse move?

I use libinput in order to intercept host input events.
