Yet another try with VFIO on SPAPR (server PPC64). Changes: v3 -> v4: * addressed all comments from Alex Williamson * moved spapr-pci-phb-vfio-phb to new file * split spapr-pci-phb-vfio to many smaller patches
The "spapr vfio: add vfio_container_spapr_get_info()" needs kernel headers update (v3.11-rc6); The "spapr kvm vfio: enable in-kernel acceleration" needs a kernel patch which is not in the kernel yet and posted separately as "[PATCH v9 00/13] KVM: PPC: IOMMU in-kernel handling of VFIO". More details in the individual patches commit messages.
