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.

Hello everyone,
I managed to solve my problem after spending quite a bit of time on it, so I thought I'd create my first guide on GitHub. Perhaps it will be helpful to someone ;)

Its not working on my Beelink Q 12 Pro.

Maybe the Problem is- i just have 1 VGA-raw device
Code: 
root@proxmox:~# lspci -nnk

        DeviceName: Onboard - Other

        DeviceName: Onboard - Video
        Subsystem: Intel Corporation Alder Lake-N [UHD Graphics] [8086:7270]
        Kernel driver in use: vfio-pci

00:14.0 USB controller [0c03]: Intel Corporation Alder Lake-N PCH USB 3.2 xHCI Host Controller [8086:54ed]
        DeviceName: Onboard - Other

I did everything like you described, but no sucess. :(
MOK doesnt work for me. But i did´nt have secure boot in my optinion.
Code: 
root@proxmox:~# mokutil --sb-state
SecureBoot disabled
Platform is in Setup Mode

For me it seems the part with dkms is not working. The dkms.conf doesnt change on your code.
Also the dkms.conf inside /etc/modprobe.d seems to be empty.
I tried the passthrough before and think i have some rest code there...

Do you have a hint with the "other" VGA-devices. I just have the 00:02.0 VGA, i think this could be the problem.
I posted the same on your github, Maybe you have an idea.
 
I am having the same issue (Bosgamepc P2), followed guide from GitHub but Windows 11 23H2 shows error even after install of Intel graphics suite. Had a look in BIOS/UEFI for settings but couldn't find them so contacted manufacturer.

Code: 
grep VGA

excellent support from Bosgamepc, support enabled advanced settings in BIOS which enabled them to Enable SR-IOV. I will try now to share it across LXCs and VMs.
 
great, I'm waiting for information whether it was possible to start correctly. To enable advanced bios settings what did you have to do just out of curiosity :D
