WRX90 IOMMU groups list

Hardware Hub Motherboards
1

Hi good people,

I planned to get an Asus WRX90E Sage motherboard to dive into VFIO GPU passthrough.

What i’d really like to know is how are IOMMU groups.

Could anyone paste there the result of that script:

#!/bin/bash

shopt -s nullglob
lastgroup=""
for g in `find /sys/kernel/iommu_groups/* -maxdepth 0 -type d | sort -V`; do
    for d in $g/devices/*; do
        if [ "${g##*/}" != "$lastgroup" ]; then
            echo -en "Group ${g##*/}:\t"
        else
            echo -en "\t\t"
        fi
        lastgroup=${g##*/}
        lspci -nms ${d##*/} | awk -F'"' '{printf "[%s:%s]", $4, $6}'
        if [[ -e "$d"/reset ]]; then echo -en " [R] "; else echo -en "     "; fi

        lspci -mms ${d##*/} | awk -F'"' '{printf "%s %-40s %s\n", $1, $2, $6}'
        for u in ${d}/usb*/; do
            bus=$(cat "${u}/busnum")
            lsusb -s $bus: | \
                awk '{gsub(/:/,"",$4); printf "%s|%s %s %s %s|", $6, $1, $2, $3, $4; for(i=7;i<=NF;i++){printf "%s ", $i}; printf "\n"}' | \
                awk -F'|' '{printf "USB:\t\t[%s]\t\t %-40s %s\n", $1, $2, $3}'
        done
    done
done

This script was found on gist dot github dot com and the author is r15ch13 and the script name is iommu.sh

Best regards,

Hi @lePagu

Just finished my build → Asus WRX 90 - 7975WX.

Here is the output of the script, BTW PCI passthrough works great for my RTX 3090 passed to a VM for gaming.

Hi @mikeone

First, thank you for sharing ; )

Here’s mine, very similar.

I can see only one discrete GPU in your list and I’m wondering how you managed that. Were you able to fully use ASPEED graphic card? Here, while booting and still in pre-grub process, both screen (DP from nvidia card and VGA/db15 from ASPEED) receive data and are showing things but as soon as grub is loaded, the ASPEED connected screen receives no more video flow.

Are you using network console for the host?

Best regards,

mathias
