Xorg.0.log, lspci and dmesg outputs.

MSI U180 atom netbook using gma500 driver works fine if the kernel is build as
32bit however if I build the kernel as 64bit the Xserver fails to start and
reports:

[    27.260] (EE) /dev/dri/card0: failed to set DRM interface version 1.4:
Inappropriate ioctl for device

Please find attached Xorg.0.log, lspci and dmesg outputs.

Any suggestions as to what is wrong ?

Hi Stuart

Did you try with a 64-bit userspace? I haven't tried gma500 on a 64-bit system
so not sure what the status is. GPU can only address 32-bit so there could be
interesting problems.

Hi Patrik,

No I have not tried a 64-bit userspace. I only planned on using a 32-bit user
space. I use LFS/BLFS for my systems so I could try and build a cut down 64-bit
user space if you think it will help. These are not the quickest machines so it
may take me some time.

Add compat ioctl

Turns out we didn't have compat_ioctl hooked up. Does the patch I attached fix
your problem?

Hi Patrik,

I have checked both linux-4.7 and linux-4.8-rc1 and this fix has not made it
through, when do you think it will be included ?

Thanks.

Hi Stuart,

The fix is available now in most stable kernels. Can you confirm and close the
bug if everything is fine?
