This is related to bug 604966. An equivalent call to iopl(3) as in attachment 366092 works in this case as well.
Alex, do you know why qemu in *some* cases behaves differently here?
If you don't,
Seems so. :-(
we probably should use a different patch which only sets iopl(3) while sending the command, and reverts this effect afterwards directly afterwards.
That would be in shared/vmmouse_proto.c:VMMouseProto_SendCmd() right before/after calling VMMouseProtoInOut(). Makes perfectly sense to me.
Still, I don't see where in vmmouse_proto.c the io port is actually accessed...
Obviously that's in VMMouseProtoInOut(...) __asm__ __volatile__( Or what do you mean exactly?
Also I don't know how to detect the current iopl level, so you can re-set it afterwards again.
Me not either. Can we assume that the Xserver runs as a "normal process"? # man iopl [...] The I/O privilege level for a normal process is 0. [...] Then it would be easy, but I doubt that. Maybe it's Level 1, maybe it's level 2. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Apparently information flow stopped there :). I'm not aware of any way to detect the current io privilege level. I'm missing the requirement for it though. Why would you need to change it back when setting it to 3? Just let X access any io port when we have the vmmouse drive in use. Btw, the levels seem to indicate the rings in the x86 cpu. Ring 0 is kernel space, ring 3 is user space. Rings 1 and 2 are unused on i386 and are non-existent on x86_64. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I'm just wondering, whether it's a good idea to switch the Xserver in between to user space. I still would expect problems when trying to do that. Therefore it might be better to switch back to kernel space.

That's what I was afraid of. I guess we don't want these switches. At least not that often. AFAIK they are rather CPU expensive. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This patch enables hardware access using Xserver's xf86EnableIO function. It is the same approach as in xf86-input-keyboard. This should be used instead of xf86-input-vmmouse-iopl.diff, results: * The iopl is no longer called before and after every outl. * It won't accidentally switch to iopl(0) because of wrong EFLAGS value in XEN in VMWARE.
