[Intel-gfx] xf86-video-intel hits an assert when using dri and xorg is not suid root

[Hans de Goede]

Hi,

When trying to run the latest xorg + intel drv, with dri3, with Xorg not
running as root, the followin assert in src/intel_device.c: authorise() :

assert(is_i915_gem(fd));

Triggers, this is caused by the DRM_IOCTL_I915_GETPARAM ioctl in
is_i915_gem() failing with -EACCESS in this case.

I thought that the use of rendernodes should work as normal user ?

Regards,

Hans
