# GPU Passthrough on Linux

## Enable IOMMU

```bash
sudo vim /etc/default/grub
```

Add amd_iommu=on iommu=pt

`GRUB_CMDLINE_LINUX_DEFAULT="... amd_iommu=on iommu=pt"`

```bash
sudo grub-mkconfig -o /boot/grub/grub.cfg
sudo reboot
```

Verify

```bash
sudo dmesg | grep -i iommu
```

## Find GPU IDs

```bash
lspci -nn | grep -E "VGA|Audio"
```

In my case, I get

- `10de:28a0`
- `10de:22be`

## VFIO Module Options

```bash
sudo vim /etc/modprobe.d/vfio.conf
```

```bash
options vfio-pci ids=10de:28a0,10de:22be
```
