anchor.diff:  . Identify the vendor IDs for the passthrough GPU: `lspci -ns 28:00`
   .. The vendor ID for my GPU VGA device: `10de:1b80`
   .. The vendor ID for my GPU Audio device: `10de:10f0`
  -. Update module settings;
  -.. Connect both of your IDs into a comma separate list like `10de:1b80,10de:10f0` and update the "ids" parameter in the following command.
  -.. Type: `echo "options vfio-pci ids=*10de:1b80,10de:10f0*" > /etc/modprobe.d/vfio.conf`
  +
  +To enable kvm passthrough, add the following module options (including the comma separated vendor IDs identified in the prior step):
  +
  +. Type: `vi /etc/modprobe.d/kvm.conf`
  +. Enter edit mode: `i`
  +.. `options vfio-pci         ids=*10de:1b80,10de:10f0*`

  +. Exit edit mode: <esc>
  +. Save and exit: `wq <enter>`
  +
  +// avic=1
  +//.. `options vfio-pci         disable_vga=1`
  +
  +Update boot settings to enable IOMMU with pass-through mode:
  +
  +. Type: `vi /etc/default/grub`
  +. Enter edit mode: `i`
  +.. Change: `GRUB_CMDLINE_LINUX_DEFAULT="quiet"`
  +.. To: `GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on iommu=pt"`
  +. Exit edit mode: <esc>
  +. Save and exit: `wq <enter>`

positive.code: 
  GPU Passthrough allows our VM to access GPU hardware for graphics and for computation (i.e. deep learning). To enable, we must update our settings for IOMMU support icluding interrupt remapping, and include additional Linux modules.
  
  Update boot settings:

  Update modules settings:
  
  . Type: `vi /etc/modules`
  .. Enter edit mode: `i`
  .. Add: `vfio`
  .. Add: `vfio_iommu_type1`
  .. Add: `vfio_pci`
