Hi everyone,

I’ve set up PCI Passthrough on Proxmox following these guides:
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
 
Here’s a possible response to continue the discussion:



Thanks for your reply!


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

Code: 
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?
