If this is against any rules, apologies.
There seems to be a dearth of information regarding the implementation of AMD-Vi and IOMMU groupings in threadripper. If anyone who has threadripper and is willing could post their IOMMU output along with their cpu and motherboard models, it would be greatly appreciated.
Details are in the first few steps of this wiki page https://wiki.archlinux.org/index.php/PC … h_via_OVMF. I will also list them below.
Add this kernel boot option
amd_iommu=onRun this script
#!/bin/bash
shopt -s nullglob
for d in /sys/kernel/iommu_groups/*/devices/*; do
n=${d#*/iommu_groups/*}; n=${n%%/*};
printf 'IOMMU Group %s ' "$n";
lspci -nns "${d##*/}";
done;And then link the output here with the cpu and motherboard models. Thanks in advance.

Awesome, much appreciated! Apparently the NPT patch for Ryzen CPUs is slated for 4.15. I'm not sure if it fixes threadripper issues or just ryzen but, regardless things are looking up for AMD VFIO.
