This repo serves as a way for me to remember how to passthrough an AMD GPU to and from various QEMU VMs.

VFIO AMD Passthrough

A little tutorial for myself to remember how to set this up.

Installation

Modify GRUB

Modify the grub config by running the grub_setup.sh. The file must first be made executable using chmod. Make sure to run as root.

  chmod +x ./grub_setup.sh
  sudo ./grub_setup.sh

After this step you must be reboot and if you need to do something after just press n for no or stop the script using CTRL + C.

Install vendor-reset

Since we have an AMD GPU 😔. We are prone to the infamouse reset bug. This solution attempts to resolve that. Just go to the command line and do this.

    yay -S vendor-reset-dkms-git
    echo "vendor-reset" | sudo tee /etc/modules-load.d/vendor-reset.conf

Congratulations!, no more reset bugs, I hope.

Setup libvirt

You're almost at the finish line, now you just need to run libvirt_setup.sh and you're done. Make sure to run as root.

  chmod +x ./libvirt_setup.sh
  sudo ./libvirt_setup.sh

Nice you're done I think.
