Hello everyone, I'm new to the forum, so if possible, I would like to ask for your understanding :)

CPU: N305


I have a problem with configuring the correct operation of transferring the Intel iGPU to a machine on Linux (I want to put Jellyfin there and in the future a remote desktop on another machine).

I've been doing this for a good week now and I'm stuck. I followed these guides, but to no avail (maybe I missed something):
- https://www.derekseaman.com/2023/11...u-vt-d-passthrough-with-intel-alder-lake.html
- https://github.com/intel-gpu/intel-gpu-firmware?tab=readme-ov-file
- https://github.com/strongtz/i915-sriov-dkms
- https://github.com/strongtz/i915-sriov-dkms/issues/103
- https://jellyfin.org/docs/general/administration/hardware-acceleration/intel/
- https://www.reddit.com/r/Proxmox/comments/190ewcc/devdri_missing_broken_igpu_passthrough/

It seems to continue to load the card into the system when I start the VM

Before start VM

I would be very grateful for any advice :)

Hello, I'm glad you asked the question because I thought the topic was completely dead :D
The problem is that even after this configuration, I am not able to transfer the graphics card to Linux. Device not showing in /dev/dri/...

I would like to skip LXC and install a typical virtualized Linux.
I also want the card to work on Windows. It is visible in the task manager, but it does not appear to be running in the system.
