And the behaviour of the swiotlb disabling will have to change (this patchset is a bit of a preparation for now) as we now use per-device dma_ops and the dma-iommu can dip into the swiotlb pool for untrusted devices. In practive we'll basically have to always initialize the swiotlb buffer now. _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
