Add support for emulating Intel IOMMU according to the VT-d specification for the q35 chipset machine. Implement the logics for DMAR (DMA remapping) without PASID support. The emulation supports register-based invalidation and primary fault logging. Signed-off-by: Le Tan <tamlokveer@gmail.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S.
