...<peng.fan at nxp.com> > > Isn't there some way to use VIRTIO_F_IOMMU_PLATFORM for this? > Xen was there first, but everyone else is using that now. Unfortunately it is complicated and it is not related to VIRTIO_F_IOMMU_PLATFORM :-( The Xen subsystem in Linux uses dma_ops via swiotlb_xen to translate foreign mappings (memory coming from other VMs) to physical addresses. On x86, it also uses dma_ops to translate Linux's idea of a physical address into a real physical address (this is unneeded on ARM.) So regardless of VIRTIO_F_IOMMU_PLATFORM, dma_ops should be used on Xen/x86...
