I have a lingering issue, perhaps someone is able to help me. My windows vm works in every way but I am unable to set display:none and primary select the Radeon Graphics card and have it succeed to display video. It works flawlessly however without no video. After normal shutdown if I add back...

Good point ; I would retract the whole post if I could. I finally found the TOOLS section of that sight which solved my problems. If I had only been aware that the tools I needed were there all along. FINALLY the artifacts are gone and hash is different on my Vbios .rom and GOP .bin.

Hello everyone, I'm hoping someone can point me in the right direction. I'm trying to set up GPU passthrough on a brand new system based on the Ryzen 9 9955HX (Zen 5) processor using Proxmox VE 8.x. The integrated graphics are the Granite Ridge [Radeon Graphics] [1002:13c0]. I followed the...

Have you tried VFIO passthrough (what vender-reset enables) with recent kernels to know if they can get it from 80 % - > 100%. depleting that one or two failures i get to display passthrough going solid green color. That is until host pve is reset.. anyways .. Or can you confirm this is fools...

Hi uzumo First and foremost, thank you. Your guidance and the resources you pointed to were absolutely critical in finally getting this working. After weeks of struggle, we have a stable passthrough setup on our Minisforum MS-A2 with the Granite Ridge iGPU (`1002:13c0`). Your patience and...

Very wise indeed. Pnputil is a fantastic idea. As stupid and as simple as it is would be, might be good to make it into a background process with a watchdog. Not like its necessary but that would be a default go to when building a vm ;) ... Thanks for the advice I will have more time to tinker...

Success! Thank you uzumo! I wanted to provide a final update: passthrough is now working perfectly! After many days of extensive troubleshooting, trying various kernels (6.8.12-11-pve, 6.14.11-2-pve), meticulously configuring vfio-pci binding, blacklists, complex GRUB parameters, and...

Hi Uzomo / everyone, Just a quick update on the VBIOS file (AMDGopDriver_9800x3d.rom) investigation. I tested the romfile= parameter extensively, primarily using the Ubuntu Live CD as a diagnostic tool, and here's what I observed: Without romfile=: The Ubuntu Live CD boots successfully...

Hi @abl030, Thank you so much for your detailed posts and confirmation that this setup can work. Your input was invaluable in guiding my troubleshooting. I wanted to provide a specific update regarding the AMDGopDriver_9800x3d.rom file you shared from the isc30/ryzen-gpu-passthrough-proxmox...

Thank you for the response and for pointing out the VBIOS/GOP requirement. You are absolutely correct, and it's a detail I had overlooked in my initial troubleshooting marathon. The fact that an Ubuntu Live CD boots successfully on the passed-through GPU indicates that Linux can initialize the...

Proxmox 9.0 + AMD Radeon iGPU (Granite Ridge) Passthrough: A Desperate Plea for Help Hardware: Host: Minisforum MS-A2 (Ryzen 7 9800X3D, Granite Ridge iGPU 1002:13c0) VM: Windows 11 Pro (24H2) Proxmox Version: 9.0 (Kernel 6.14.11-2-pve) The Problem: "Loading Initial ramdisk" Hang with Error...

Good news I think you are looking for the following entry ; edit /etc/pve/nodes/SS1/qemu-server/ (x).conf where x is your vmid add args: -cpu host,kvm=off this will kill internal virtualization function calls for making VM's within the vm. This to my knowledge fixes the glitch but...

I am looking to nullify much of the visualization in order to maximize the 4 gpu independant passthrough with proper graphics via pass through.

yes this is for local use

I am lost what qm smhowcmd is exactly and when to apply it?

oh darn thats quite a problem then indeed. thanks for the information none the less.

Very informed advice indeed. I cannot test this atm. Assuming that solves the problem how would this be resolved. Do you know various commands I could use to assess what is going on. ?

Fair enough; but is there a way to understand this logic, or try and comprehend how the computer is canibolizing the cores. In my case the best EVER I have seen was 14 cores... ( OF 36 ?_)) I need someone to explain throughly to me how the cpu setting allocation on the VM works the manual is...

There seems to be no indication as to the best way to launch my VM's with all the core's in the system in this case 36 are advertised on the Node System summary panel. This is comprised of 1 socket, 18 Core (E5-2699 v3) and 36 with hyper threading. It doesn't make sense when I have only 4 vm's...
