I'll try to give it a hit in the next few days then. Installed in my Malta I have a DEFPA, which is about as serious a DMA user as a piece of classic PCI hardware could be. I need to debug the issue of another DEFPA not working with my POWER9 system, possibly due to an IOMMU handling bug (hopefully not broken host hardware), so I'll take the opportunity and do it all at once.
