I have recently found out that no iommu_groups could be found under /sys/ on a P8. That prevents PCI passthrough from working. During my investigation, I found out there seems to be a missing iommu_register_group for PHB3. The following patch seems to fix the problem. After applying it, I see iommu_groups under /sys/kernel/iommu_groups/, and can also bind vfio-pci to an adapter, which gives me a device at /dev/vfio/.
