printf "This script assumes a few things:
* You have already enabled IOMMU, VT-d and/or AMD-v inside your UEFI/BIOS advanced settings.
* You have already added \"iommu=pt intel_iommu=on\" or \"iommu=pt amd_iommu=on\" to your
kernel boot arguments and booted your system with these kernel arguments active.
* You are comfortable with navigating and changing settings in your UEFI/BIOS.
* You know how edit your bootloader configuration.
* Your Linux distribution is an EFI installation (important to get VFIO working).

quirk with IOMMU on some boards.
This is a list of prerequisites you will be needing before starting with VFIO:
* 2 GPUs (iGPU/APU included)
* 2 very different GPUs (iGPU/APU included), the easiest combination is to have 2 from different vendors (amd/intel/nvidia)
if both cards share the same device id (ex: both are identified as 1022:145c), then passthrough will most likely
not be possible unless you swap out one of the cards.
* A \"ghost display\" dummy plug for your second graphic card (or having it hooked to a separate input on your monitor).
* If you are planning to use the inegrated GPU on your CPU, make sure your monitor is connected to it before continuing.
* Preferably a motherboard verified to work with IOMMU and with good IOMMU groups.
https://reddit.com/r/vfio is a good resource for this info.
