[BUG] Intel iGPU 15th Gen Arrow Lake "Unknown Intel" - Transcode Fails

[moogoos]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When I passthrough /dev/dri, plex can't see what GPU it is. It says "Unknown Intel".

More context here: https://forums.plex.tv/t/intel-arrow-lake-igpu-intel-15th-gen-support/898244

Expected Behavior

It should show this: https://imgur.com/a/QZveNIe instead

Steps To Reproduce

Setup a docker plex instance of linuxserver and pass the device for an Arrow Lake iGPU

Environment

Proxmox>Ubuntu 24.10 w/kernel 6.12

ARC GPU A310 works fine
Intel 14500 works fine
Happens on both truenas SCALE and Ubuntu 24.10 VM docker
Running plex directly on the Ubuntu host, where i'm passing /dev/dri works fine. It's only the docker images that don't seem to work. PMS docker has the same issue so tried linuxserver image, same issue. Switching to passthrough the ARC card works seamlessly with same configs

CPU architecture

x86-64

Docker creation

docker compose

I rebuilt the plexinc docker image with 24.10 and this image works correctly
