[PATCH RFC 0/3] virtio-pci: iommu support
This is an attempt to allow enabling IOMMU for DMA.
Design:
- new feature bit IOMMU_PLATFORM which means
host won't bypass IOMMU
- virtio core uses DMA API if it sees IOMMU_PLATFORM
- add quirk for vfio to disable device unless IOMMU_PLATFORM is set
or the no-iommu mode is enabled
- while I'm not sure how it will be used, it seems like a good idea to
also have
