All AMD CPUs from Bulldozer onwards should be compatible.
2) Get device IDs:
lspci -nn
`lspci -nn`
3) Enable IOMMU in GRUB (check Intel or AMD commands below - choose the right one)
nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"
GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on"
save and exit
5) run the command "update-grub"
now reboot
`GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"`
6) Enable VFIO Modules
nano /etc/modules
`GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on"`
Save and exit
4) run the command `"update-grub"` now reboot
5) Enable VFIO Modules
`nano /etc/modules`
Add the following modules:
```
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
```
Then, save and exit
Next run:
update-initramfs -u -k all
and reboot
6) `update-initramfs -u -k all` and reboot
7) GPU Isolation From the Host (amend the below to include the IDs of the device you want to isolate)
echo "options vfio-pci ids=10de:1381,10de:0fbc disable_vga=1" > /etc/modprobe.d/vfio.conf
`echo "options vfio-pci ids=10de:1381,10de:0fbc disable_vga=1" > /etc/modprobe.d/vfio.conf`
8) Blacklist GPU drivers (here are all that you would ever need)
```
echo "blacklist radeon" >> /etc/modprobe.d/blacklist.conf
echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf
echo "blacklist nvidia" >> /etc/modprobe.d/blacklist.conf
echo "blacklist nvidiafb" >> /etc/modprobe.d/blacklist.conf
echo "blacklist nvidia_drm" >> /etc/modprobe.d/blacklist.conf
```
9) Create a new VM and add the GPU via hardware menu
You may need to set it as primary GPU
