Hi Chris,

Would it be possible to include the total size of the mappable region
as well? Currently libdrm_intel has a:
/* XXX add a query for the kernel value? */
in drm_intel_get_aperture_sizes(), and some fallback code that uses
libpciaccess to figure out the size of the aperture. That is a bit of
a problem for systems like OpenBSD that restrict userland access to
PCI config space.
Thanks,
Mark
