Here is my preferred plan: 1) wait for my series to support the min alignment in swiotlb to land in Linus tree 2) I'll resend my series with the further swiotlb cleanup and refactoring, which includes a slightly rebased version of your patch to add the io_tlb_mem structure 3) resend your series on top of that as a baseline This is my current WIP tree for 2: http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/swiotlb-struct _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
