[SOLVED] Proxmox PCI Passthrough (AMD iGPU) missing /dev/dri/renderD128

[Xerhaxs]

Hi everyone,

I’ve set up PCI Passthrough on Proxmox following these guides:

• https://pve.proxmox.com/wiki/PCI_Passthrough#Enable_the_IOMMU
• https://forum.proxmox.com/threads/gpu-passthrough-ryzen-4600g-apu.120151/post-524787

It’s mostly working — I can pass my AMD iGPU (Ryzen 7 5600) to a TrueNAS VM. However, inside the VM, I only see /dev/dri/card0, but not /dev/dri/renderD128, which I need for hardware transcoding in Jellyfin.

Does anyone know how to fix this or what I might have missed?

Thanks in advance!

Take a look with lspci, if the card is passed through. Other than that, probably install the necessary modules or drivers. See here: https://wiki.archlinux.org/title/AMDGPU

Thanks for your reply!


I checked with lspci, and it seems the iGPU is being passed through to the VM:

06:1c.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Raphael (rev c6)

I also installed mesa-utils in the TrueNAS VM, but unfortunately, it didn’t resolve the issue. I still only see /dev/dri/card0 and not /dev/dri/renderD128.

Any ideas on what else I could try?

Set the kernel parameters for the moduls?

What do you mean? / How do I do that?

I've solved the problem so far, but the transcoding in jellyfin is still not working.
The rom image was missing, but the following guide had a solution.

Solved the issue. The rest was a wrong configure jellyfin installation. xD
