intel 185H/155H iGPU

[Magi]

Anyone here with intel 185H/155H CPU? Are you able to setup LXC with iGPU working?
Intel has stated that this series of iGPU got no virtualization support. so VM is not possible.
but in theory it should work on LXC. Somehow I'm struggling to make it work for tdarr to encode.

in LXC it shows

[goofy@donald ~]$ ls -l /dev/dri

NVM... I sorted it all out
I didn't map it correctly
the host has
44 video
104 render
and i need to map LXC
39 video
105 render

but now tdarr docker container has a different set of groups

I have an intel 185H, and while I have vainfo showing up correctly, I cannot get the GPU to map to an LXC...

Can you share your config for an LXC you were able to map the GPU to?
