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!

TY for info.
I finally found some real info on ARI.
https://us-east.manta.joyent.com/jmc/public/opensolaris/ARChive/FWARC/2010/063/Materials/ari-support.txt
Apparently SR-IOV doesn't actually require it, it is only needed for
more than 8 total functions per device.
I will continue troubleshooting and get back to you, SR-IOV is an
important feature for today's modern servers so I will try to figure it out.
I would DIY but hardware engineering is currently above my paygrade, but
when I get a job I am definitely going to do some bankrollin'
