[Qemu-devel] "invisible wall" patch

[Qemu-devel] "invisible wall" patch

[Julian Seward]

Could somebody please commit, or at least consider committing, 
Anthony Liguori's "invisible wall" patch, shown at 
http://lists.gnu.org/archive/html/qemu-devel/2006-05/msg00112.html ?

Without it, QEMU is essentially unusable on my SuSE 10 host; with it,
the mouse stuff works perfectly.  A couple of other people on that
thread had similar experiences with it.

I'll add my voice to this - with WinXP and Win2000 guests, without this 
patch they were virtually unusable.  They work fine with it.

I also use this patch to my full satisfaction for my Slackware package
of QEMU at http://www.slackware.com/~alien/slackbuilds/qemu/

With the addition of the VNC capability, this mouse misbehaviour was
introduced and never resolved which is a pity really. Also, VNC
functionality is still basically where it was when it was added to
QEMU - which is barely above useable status. I liked the functionality
offered by the libvncserver patch better but can no longer apply that.
Is someone going to take up adding the missing pieces to VNC
functionality? The suggested patch in
http://lists.gnu.org/archive/html/qemu-devel/2006-05/msg00142.html
might help here, too.

What functionality are you referring to?

The patch works perfectly here (qemu 0.8.1 on Windows XP host). Without 
it I always get the invisible wall if I leave mousegrab and enter it 
again close to a window border.
It seems to me that SDL only reports pointer-deltas based on the 
movement of its own pointer (which is set invisible) and when this 
invisible pointer hits the window border you therefor only get delta=0 
even if the guest OS pointer is still somewhere in midscreen. (Setting 
the SDL pointer always visible gives a good illustration of what is 
going on.)
The guest-OS rather expects raw mouse movement deltas, than the filtered 
SDL-pointer deltas.

Somehow the patch seems to solve this, but I can't say that I understand 
how (not having looked into the SDL source code).

This patch has been around for a while but never committed to the 
mainstream.
Are there any known issues with the patch?

Huh?  Fabrice committed it some time around Tuesday.  I've been
using it 8+ hours/day since then and it seems fine to me.

I have not updated my sources this week. But in the past few months I had to 
manually apply the patch to make Qemu workable. And I use it a lot. Thanks 
for a great product.

Hi All,

for what its worth, I've also been using the latest from CVS (with the
"invisible wall" patch) and it works great.

Thanks!
Thomas
