GPU Passthrough on Arch

This is the steps I used to successfully get GPU passthrough on Arch after switching from Debian.

Enable IOMMU

1. Open /etc/default/grub
2. Add intel_iommu=on and iommu=pt to the GRUB_CMDLINE_LINUX_DEFUALT field.
3. Save
4. Run sudo update-grub
5. Running this script:

using System.Collections.Generic;
using AirSimUnity.DroneStructs;
using UnityEngine;

namespace AirSimUnity
{
[RequireComponent(typeof(Drone))]
public class DroneControllerInput : MonoBehaviour
{

/*
Fixes a mesh's rotation after importing it from Blender. In Blender, the Z axis points in the
"up" direction, while in Unity, Z points in the "forward" direction. This script rotates the
mesh's vertices so that it is upright again.

To use this, create an object from a mesh in the hierarchy view, then locate the Mesh Filter
in the inspector. There, click on the new "Fix Rotation" button.
