Oops, seems I failed to send it out (I happened to know it when
I was checking the patchwork status: I didn't find my comment).
I also happened to find out that I failed to receive quite many
emails, including some patches. Seems something went wrong :(

I know RedHat is working on a vIOMMU so I guess this work is related to
that effort, but it is a surprise virtio using IOMMU. I thought IOMMU just
made sense when using SRIOV. My second guess is using IOMMU with virtio is
a matter of security, but by other hand, virtio + IOMMU could imply serious

Good news!
What are the requirements for Qemu and Linux version numbers please?
Virtio pmd doesn't support VFIO in the past since devices bypass IOMMU
completely. But recently, the work of making virtio device work with
IOMMU is near to complete. So this patch make pmd support IOMMU by:
- Allow VFIO mapping by setting RTE_PCI_DRV_NEED_MAPPING flag
- Negotiate feature
