Implement the virtio-iommu driver, following specification v0.8 [1]. Changes since v2 [2]: * Patches 2-4 allow virtio-iommu to use the PCI transport, since QEMU would like to phase out the MMIO transport. This produces a complex topology where the programming interface of the IOMMU could appear lower than the endpoints that it translates. It's not unheard of (e.g. AMD IOMMU), and the

Setting the IF flag can cause an VM exit. So we should avoid touching the IF flag until absolutely necessary. This patch change the way the paravirt arch_local_irq_restore() works by checking the previous flags value and call arch_local_irq_enable() only if the IF flag was set previously. On a 32 vCPUs KVM guest running the AIM7 five-sec workload, the performance increased slightly from 302136.32
