vfio-single-amdgpu-passthrough VS vfio

This guide was created by me a while back and I still use it today with on latest fedora: https://github.com/cosminmocan/vfio-single-amdgpu-passthrough

My problem is, after doing all the setup in the video and finally launching the VM, there is no signal for EVER. I waited 10 minutes for something to happen with no avail. Is my problem my second monitor? I used the scripts from this GitHub

While I cannot help you to much without at least dmesg output, I can provide you with my own guide about doing single gpu passtrough using AMD gpus: https://github.com/cosminmocan/vfio-single-amdgpu-passthrough

It's a bit of a stretch , but take a look at this if you want, it's my single gpu guid e for amd cards, while a bit overkill for you simple setup, you might find it useful: https://github.com/cosminmocan/vfio-single-amdgpu-passthrough

I created a script inspired from this vfio-single-amdgpu-passthrough repo which detaches the console from the card and unloads some modules, namely: drm drm_kms_helper i2c_piix4

I used this guide for both my start up and stop scripts, and I am only having a problem with the stop script. Even activating the script manually causes the black screen bug(even though the script finishes). I would really appreciate some help. Thanks for your time!!

The following guide was written by me and i think it would fit your purpose : https://github.com/cosminmocan/vfio-single-amdgpu-passthrough

https://github.com/cosminmocan/vfio-single-amdgpu-passthrough (this is mine :) , AMD radeon)

I was mainly following this guide to setup the VM and scripts: https://gitlab.com/Karuri/vfio

I've successfully set up single GPU passthrough as per https://gitlab.com/Karuri/vfio and https://github.com/joeknock90/Single-GPU-Passthrough .

- and a few other things mentioned here and here,

great thanks for the tip! havnt checked the logs for libvirt as i thought it was an osx issue. im using manjaro host, and have originally installed the vm using this https://github.com/foxlet/macOS-Simple-KVM, and this for the passthrough https://gitlab.com/Karuri/vfio

I used to have an RX580-based single GPU passthrough setup. You likely need the vendor reset module, since hot-plugging Polaris 10 GPUs is a bit buggy and can cause GPU lockups. It might also be worth dumping your GPU bios and configuring libvirt to use it so you get a visible boot screen (tool). I think I mostly followed this guide, however it hasn't been updated in quite a while it seems.

If you're up to the task you can follow this guide to get it working.

vfio-single-gpu-passthrough (this is for single gpu system, I link it for the section regarding hugepages, isolation, pinning & cpu governor which massively improved performance. It use script to dynamically run these only when you start a vm, so you can still use all of your cores when you stop the vm)
