[RFE] Intel GPU (iGPU) support

[tardich]

Current situation

iGPU is enabled on the BIOS. But I can't seem to find a way to enable it in the kernel so I can use it

Impact

Workloads that can make use of GPU's aren't able to interact with the integrated GPU

Ideal future situation

iGPU becomes available to use

This is present in Flatcar release >=4284, currently in the alpha channel. What's your usecase, if I may ask?

See also previous discussions in: https://github.com/flatcar/Flatcar/issues/1306.

I'm working with Frigate from a docker container, I have a Coral TPU installed, but would also make use of the iGPU feature of my board to help out.

I am setting up Flatcar on an older Intel NUC to run various self-hosted services and was going to move my media server to it, but found I am unable to take advantage of hardware assisted transcoding without the integrated GPU support, so I would add another upvote to this issue getting addressed sooner.

I need Intel gpu too for my media server , for example for jellyfin

This support is available in the Flatcar beta channel since June with 4344.1.0.

Yes I know, I think it would have become stable with the August stable release.

I'm running version beta 4372.1.0, followed this link: https://3os.org/infrastructure/proxmox/gpu-passthrough/igpu-split-passthrough/

Still not getting the /dev/dri folder in the flatcar vm. Running Proxmox 8.4.11 and a i7 7700T. Did anyone got this to work? @leon-ITA

[leon-ITA]

I use flat car in bare metal installation, if you run flatcar into a virtual machine the dev/dri folder is void, this is my experience!

For instance, if I run flatcar into oracle virtual machine dev/dri is void, While if I install flatcar on the server (miniPC) dev/dri exist and it is populated

I got it to work finally on Flatcar 4426.1.0 (beta) running on Proxmox 8.1.4. Should work with the earlier versions in Beta too. Got a Lenovo tiny with HD graphics 630

Followed the instructions: https://3os.org/infrastructure/proxmox/gpu-passthrough/igpu-split-passthrough/#proxmox-configuration-for-gvt-g-split-passthrough

Then the missing bits:

1. On the proxmox host

On Proxmox:
uuidgen

echo ee014424-f7ef-43f2-877b-1a44aa1ccc16 > /sys/bus/pci/devices/0000:00:02.0/mdev_supported_types/i915-GVTg_V5_8/create
ls /sys/bus/mdev/devices/

Before adding to the VM this should show '1'

2. Inside of Flatcar

#module is not loaded by default
lsmod | grep i915 
modprobe i915
sudo tee /etc/modules-load.d/i915.conf <<< "i915"
reboot

Result:
