[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?
