Things like reliable GGTT mappings and mirrored 3d display will need to be
to map the same object twice into the GGTT.
What's a reliable GGTT mapping and how does it differ from today's
notoriously unreliable mappings?
Ask Daniel. :P But you are probably aiming at the short commit message,
which I justify with the RFC tag. :)
As far as I understand it idea is to allow mapping a subset of an object
to work around the 256Mb limit of the mappable region. How it was
described sounded a bit like VM inside a VM but I am more interested in
the infrastructure than this particular justification.
