It seems the PCI-e root ports on the KGPE-D16 have ARI which is needed for SR-IOV, however it is not reported via # lspci -vv I assume that is why the VF's are not assigned to IOMMU groups and thus can't be assigned.
I am running coreboot v4.5 (I forgot to note this as it is another late night)
Tim was the ARI feature implemented when you guys did the programming? https://support.amd.com/TechDocs/44549.pdf
We did not explicitly enable nor verify the ARI feature as we did not need it for our internal machines. As always, this is something that we could definitely work on under contract, and I am always happy to review patches on Gerrit if you choose to tackle this on your own!
