9950x iGPU passthrough

I’m trying to passthrough the internal GPU of the 9950x into a Windows KVM VM. When I start the VM the host (linux 6.11.2) will crash will a read from NULL pointer exception.

Did anyone face the same problem or knows if its even passthrough the internal GPU ?

I’ve not done it, but I think it can be done. You’ll need the VBIOS, there are examples at Unraid Forum and Proxmox’s Forum for capturing and setting it up in the VM config.

Also, you might benefit by saving your screen’s EDID and feeding that to the VM config.

K3n.

There is a guide I have been meaning to try on GitHub

Proxmox - Ryzen 7000 series - AMD Radeon 680M/780M/RDNA2/RDNA3 GPU passthrough


This is a guide to get the Ryzen 7000 series processors with AMD Radeon 680M/780M integrated graphics or RDNA2/RDNA3 GPU running with Proxmox, GPU passthrough and UEFI included.

Confirmed list of Proxmox versions that work:

  • Proxmox 7.4
  • Proxmox 8.0 (recommended, has a newer kernel)

Confirmed list of hardware that works:

  • Ryzen 7 7735HS (RDNA2 680M Rembrandt iGPU)
  • Ryzen 7 7840HS (RDNA3 780M Phoenix iGPU)
  • Ryzen 9 7940HS (RDNA3 780M Phoenix iGPU) - thanks @mmaiero for confirming
  • Ryzen 9 7900X (RDNA2 Raphael iGPU) - thanks to @engels74 for confirming
  • Ryzen 9 7950X3D (RDNA2 Raphael iGPU) - thanks @romner-set for confirming
  • 6900XT (RDNA2 Navi 21 dGPU) - thanks @mpaulo for confirming

Perhaps you might want to give it a spin. You 9950X isn’t listed, but the same technique might work, since it’s the same iGPU.

The iGPU is identical to the one on Ryzen 7000—it is based on the RDNA 2 architecture, with just two CUs or 128 cores.

I await the good news. :slight_smile:

EDIT: ah~ it turns out the link is the same as that of the second post on the Proxmox forum linked to by @k3ninho.

Thanks @LiKenun for validating … good luck to both of you.

K3n.

I tried with 7950x (same igpu as 9950x), it didn’t work for me. I got code 43 in the vm. I gave up at the end.

Got it working by following the proxmox guide.

Uploaded the needed GPU ROM dump here:
