[SOLVED] NEED HELP to setup gpu passthrough/iommu/AMD 6500XT for gaming/f@h INTEL Alder Lake

[Redicat]

Alright, I'm guessing you have 16GB of RAM total?

Here's a list of things to do:

• Shutdown your VM.
• Change VM settings to 12GB of RAM and 1 socket, 12 cores. (Just giving a little more to Proxmox.)
• Then edit your /etc/pve/qemu-server/100.conf file.
  • set balloon: 0
  • set cpu: host
  • set hostpci0: 0000:03:00,pcie=1,x-vga=1
  • delete the args line entirely

The run these commands:

update-grub
rm -rf /etc/modprobe.d/iommu_unsafe_interrupts.conf
rm -rf /etc/modprobe.d/kvm.conf
update-initramfs -u
shutdown -r now

Done, it's still lagging/freezing each few sec

Still code 43 same as before

Still code 43 same as before

Try this:

• shutdown VM
• run echo 1 > /sys/bus/pci/devices/0000\:03\:00.0/remove
• run echo 1 > /sys/bus/pci/rescan
• startup VM

If that doesn't work, dump the text from the following commands:

• dmesg | tail -100
• tail -100 /var/log/syslog

It works but GPU is disabled in Folding@Home I got issues with the AMD software shown here....

Oooh, not sure about that one... Sounds like an uninstall/re-install thing for the drivers.

If the reset fixed the error 43, you'll need to get that command configured to run when you launch your VM.

Best approach is a hookscript:

#!/bin/bash

if [ $2 == "pre-start" ]
then
    echo "gpu-hookscript: Resetting GPU for Virtual Machine $1"
    echo 1 > /sys/bus/pci/devices/0000\:03\:00.0/remove
    echo 1 > /sys/bus/pci/rescan
fi

Use these commands to deploy it:

#create snippets folder
mkdir /var/lib/vz/snippets

#create script with content above
nano /var/lib/vz/snippets/gpu-hookscript.sh

#make it executable
chmod +x /var/lib/vz/snippets/gpu-hookscript.sh

#apply script to VM
qm set 100 --hookscript local:snippets/gpu-hookscript.sh

Actually, I think this might be because you're using both the virtual GPU and physical GPU simultaneously.


When I check the box for "Primary GPU" like shown above, it will disable the virtual GPU.

Do you have a monitor hooked up?

NOTE: Enable RDP just so you have a way to connect if needed.

Yes monitor is hooked up

HOW? it's already like that to begin with Primary GPU is on

Hmmm... Well, I don't have any experience with AMD GPUs in Proxmox.

You could try turning off you VM, setting the Display to "None" in Proxmox and restarting your VM. That might help.

Anything else not working?

Yeah... it works now with password

Did you get that hookscript configured? It should show an entry in the Task to start your VM:

OMG! IT WORKS! AMD software opens and iam Folding!
