This indicates that any choice of a different swiotlb pools needs to be hidden inside of Ń•wiotlb. The dma mapping API already provides swiotlb the addressability requirement for the device. Similarly we already have a SWIOTLB_ANY flag that switches to a 64-bit buffer by default, which we can change to, or replace with a flag that allocates an additional buffer that is not addressing limited. _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
