[PATCH 3/6] mmu: map small pages into big pages(s) by IOMMU if possible
...oth the advantages above, but your
> suggestion would take us further away from that than Vince's version.
Aha, looks like both Vince and I overlooked this point. So IIUC we
would need to make sure a GPU buffer is only ever mapped once by the
IOMMU. This means we either need to preemptively entilery map it at
some point and just keep a reference count, or keep track of which
128k ranges are already mapped (again, with a reference count to know
when to unmap them).
First solution is tempting because it is simpler, but surely there is
something wrong with it?
