Written for systems using initramfs.
|
||||
|
||||
The setup done by this script is quite complex and is prone to human error or hardware incompatibilities.
|
||||
It is HIGHLY RECOMMENDED to make a backup/snapshot of your system using something like timeshift or snapper before starting.
|
||||
|
||||
Once everything is configured, your 2nd graphic card will hopefully be dedicated for use inside a virtual machine.
|
||||
|
||||
Even though that this script is intended to make this setup easier, it is recommended that you
|
||||
read through a guide and learn what is actually being done so that you can get familiar the process.
|
||||
A full documentation for debian/ubuntu systems can be found here: https://github.com/hikariknight/vfio-setup-docs/wiki
|
||||
|
||||
Press ENTER to continue once you have made a backup of your system.

echo "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 \"$CMDLINE\" 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 and kernel arguments.
|
||||
* Your Linux distribution is an EFI installation (important to get VFIO working).
|
||||
|
||||
NOTE: If your computer no longer fully shut down after enabling IOMMU, then there is possibly a bug
|
||||
with your motherboard and a piece of hardware in your system, it only prevents you from using
|
||||
the system in a headless mode with working shutdown and is otherwise just an annoying
|
||||
quirk with IOMMU on some boards.
|
||||
|
||||
This is a list of prerequisites you will be needing before starting with VFIO:
|
||||
* 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
|
||||
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 integrated GPU on your CPU, make sure your monitor is connected to it and working/enabled 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.
|
||||
(If you are unsure, you will find out while using this script)
|
||||
|
||||
* It is also highly recommended to have access to your VM through VNC (RDP will not work) as once you pass through
|
||||
a graphic card, it will most likely not possible to interact with it through spice and the normal qemu display window!

||||
