Hi Stefano,
I've looked over xen-swiotlb in linux-next, that is with your recent changes to take dma offsets into account. One thing that puzzles me is that xen_swiotlb_map_page passes virt_to_phys(xen_io_tlb_start) as the tbl_dma_addr argument to swiotlb_tbl_map_single, despite the fact that the argument is a dma_addr_t and both other callers translate from a physical to the dma address. Was this an oversight? _______________________________________________ iommu mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/iommu
