[Qemu-devel] mouse freeze (related to new wheel mouse support?)

[Qemu-devel] mouse freeze (related to new wheel mouse support?)

[Fred]

qemu CVS snapshot Jan 24, 2005. Linux host, Windows 2000 guest.

-Start qemu. Mouse works okay.
-Reboot the guest OS: Windows Start menu -> Shutdown -> Reboot.
-When Windows comes back up, the mouse cursor does not respond.

-Start qemu. Mouse works okay.
-Reboot the guest OS: Windows Start menu -> Shutdown -> Shutdown, then 
"system_reset" in qemu console.
-When Windows comes back up, the mouse cursor does not respond.

This did not happen with the Jan 4 CVS snapshot. Could this problem be 
related to the new wheel mouse support? Sorry, I cannot fix this myself.

It may be related. I also have this problem, but it showed up only after I
manually applied the wheelmouse patch. In my case it can also show up after
changing graphics modes repeatedly.

I guess Windows 2000 enables the wheel mouse feature and the wheel is usable 
and after rebooting the device ID is wrong. I think the mouse type is 
affected by the mouse reset function (0xff). Please add this line in pckbd.c 
in the AUX_RESET section and let us know what happens:

s->mouse_type = 0;

To let everyone know,

Before adding these modifications, I have noticed the mouse in windows
2000 and windows nt (after the reboot, during installation) to act
improperly, almost as if you can disconnected the mouse and reconnected
it.

I applied this line to the AUX_RESET section as well as the
AUX_SET_DEFAULT section, and it seems to work just fine now (in nt4,
havent tested w2k yet)

I just tried this (patch attached below if you like it that way), and
tested it in Win2k with the two reboot scenarios I mentioned, as well as
by changing the graphics mode repeatedly. The mouse works beautifully.  
Thanks!

I wasn't sure if the AUX_SET_DEFAULT section was involved, since it
doesn't have a "kbd_queue(s, s->mouse_type, 1);" statement like AUX_RESET
(should it??). I stuck a print statement in the AUX_SET_DEFAULT section,
and it was never invoked during my test in win2k, but AUX_RESET was run 4
times as win2k started up.

So I'd say just edit the AUX_RESET section (patch in previous email). 
Thanks for your help guys!
