Hi all,
Having noticed very wierd behaviour of some operations under an x86
Qemu guest running on a PowerPC (32 bits), I have compiled the
following test program under Linux/i386:
#include stdio.h
#include math.h
void main()
{
float x = exp(1)*exp(1);
float y = exp(2);
printf(%f = %f\n,
I am wondering about making unified device models architecture for open
source simulators.
The device models will be used in QEMU, Bochs, Xen and other open source
simulators which would use the device models.
I would support this idea, if it was possible.
Why not ?
You always could

Yes, it also fixes that problem.

I noticed that the Windows driver does not work... it does send a bunch
of commands to the tablet, mostly resets, but then claims that it can't
discover it. I downloaded the latest driver from wacom.com. I did not
try this with a Linux guest yet maybe that should be my next

Hi!
Maybe this patch helps?
The attached patch is an updated version of your patch. With whis patch I was
able to copy files from one directory to another on a disk image. After
unmounting the image, e2fsck reported no errors on this image.

Hi Brad,
I have your patch applied and the previous one and it doesn't seem to

I've got what I have attached. I did a little bit of SDL plumbing based
