From: Oleksandr Andrushchenko <[email protected]>
It is now only possible to control if multi-touch virtual device
is created or not (via the corresponding XenStore entries),
but keyboard and pointer devices are always created.
In some cases this is not desirable. For example, if virtual
keyboard device is exposed to Android then the latter won't
automatically show on-screen keyboard as it expects that a
physical keyboard device can be used for typing.
Make it possible to configure which virtual devices are created
with module parameters:
- provide no_ptr_dev if no pointer device needs to be created
- provide no_kbd_dev if no keyboard device needs to be created
Keep old behavior by default.

Oleksandr, please give us some time. I can't speak for others, but I am
not sitting here idling and hoping that some work (e.g. patches to
review) might appear.
I have a lot of other stuff to do and will respond when I find some time
to look at your patches.
Pinging others on Monday when having sent out the patch only on Thursday
is rather unfriendly.

Really sorry about this, my bad.
I had an impression that the only change we need to
discuss was uint -> bool change which seemed rather trivial

My earlier suggestion on the option name was aimed at replacing the above with:
if (kbd_dev) {
I find it easier to read then the double negative !no_kbd_dev. But
it's only used once, so it's not a big deal either way.

Just noticed these lines now exceed 80 columns.
Otherwise it's just code motion and fine by me.

I am sorry I did not respond to the previous version until today, but I
do not think that we should be extending module parameters for this.
Protocol features are already there for absolute pointers and
multi-touch, keyboard and relative pointers should use the same
mechanism.
Thanks.
