Aorus X399 Gaming 7 - IOMMU Groupings

Aorus X399 Gaming 7 - IOMMU Groupings
« on: August 31, 2017, 11:27:13 pm »
Can someone WITH the board get a listing of the IOMMU groupings so we can see if GB did a good job or not in the BIOS? These determine how easily you can do VM passthrough of GPUs and the like. I doubt I am the only virtualisation fan who needs to know this before buying this board and a Threadripper.

To check these (and SHARE them here ;) of course) you need to:

Enable IOMMU in BIOS
Boot a Linux machine (USB stick boot is fine so a USB stick of 8Gb or so with Ubuntu live install would be fine)
Make sure you boot with kernel options including "amd_iommu=on" otherwise it wont be enable in OS, just BIOS :D

Run this as a script:
Code: [Select]
#!/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;
Share your results, please :D

if GB did a good job or not in the BIOS
Doesn't look like it. I really hope they fix this before I return the board...

That is a mess... my current Intel Xeon setup has each device neatly in its own group (well mostly)... so passthrough works. Oh dear.. looks like this board is a No No for me

Thanks for checking

It is actually not that bad. You must set IOMMU in Bios to "Enabled", then it will work. I had mine set to "Auto" and it was messing everything up. "[    0.025531] [Firmware Bug]: AMD-Vi: IOAPIC[130] not in IVRS table" issue is also gone.
