Hello all,

Just wanted to add something more to my previous mail I had posted on
mailing list. Actually I am studying the input flow from host OS to qemu
which is installed on plain linux distro like ubuntu 8.10 which I am using
currently since my aim is to add multi touch support so that the guest OS
installed inside qemu can interpret multi touch information from qemu. And
for multi-touch information on Host machine I am going to use MPX . So in
this scenario I came to know by my understanding that there may be two
channels for qemu to have inputs from host OS i.e.

1) SDL
2) VNC

So,I am confused about which way qemu uses for having input events from host
OS. Is it SDL or VNC ? Also please if anybody can suggest me some
documentation regarding all the above matter which I can refer to, it will
be better for me.

Sorry for previous inappropriate mail !

Thanks,
Amey.
