Helps with GPU passthrough

Something simple that'll be specific to me and i3 builds, however, you can use the scripts provide to help your with you single gpu passthough. Nvim script is not needed, I just love using it so I added it specifically for me.

GRUB

sudo nvim /etc/default/grub and add the following:

GRUB_CMDLINE_LINUX_DEFAULT = "... intel_iommu=on iommu=1"

or

GRUB_CMDLINE_LINUX_DEFAULT = "... amd_iommu=on iommu=pt iommu=1"

then execute sudo grub-mkconfig -o /boot/grub/grub.cfg after executing, reboot.

Virt-manager

Make sure to execute qemu-downloads.sh after rebooting

Make sure to add the following in your Virtual Machine XML file:

    <hyperv mode="custom">
      <relaxed state="on"/>
      <vapic state="on"/>
      <spinlocks state="on" retries="8191"/>
      <vendor_id state="on" value="AnythingTbh"/>
    </hyperv>
    <kvm>
      <hidden state="on"/>
    </kvm>
		...
 <cpu mode="host-passthrough" check="none" migratable="on">
