i915 support on Intel Ultra CPU #195

aznablegs · 2024-08-18T02:10:57Z

Hi there,

Thanks for the driver and guide which is very helpful. I have applied to 12th gen CPU and working like charm. Recently just bought a new mini PC with Intel Ultra CPU, seems the dkms driver doesn't work.

After dig out some document, found Intel mentioned it is not supported by SR-IOV but ATS. Any idea if I still can use your driver to support this function? Thanks.

There is a post on the official Intel forum at https://www.intel.com/content/www/us/en/support/articles/000008563/ethernet-products.html. I don’t have an Ultra PC, could you try it and see if it works successfully?

aznablegs · 2024-09-11T13:32:09Z

thanks. but seems nothing output from the scan. after some troubleshooting, I think the driver under proxmox still not fully supported under the kernel 6.8...

I tried but failed. See my comment here.

I gave it another try but the guests are still not able to use the VFs of the iGPU.

Here is what I did. See this comment for further explanations.

I guess progress for Core Ultra devices can be followed here. Currently it's not possible to use SR-IOV with Meteor Lake unless I did something wrong.

from Intel site, I just see the latest Ultra CPU doesn't support SR-IOV but sth called ATS. Still, can't find any relevant doc regarding this topic.

Meteor Lake supports GPU SR-IOV. I'm running it on Bee-Link GTi14s right now. However, i915's start is as you mentioned, not graceful.

despite all of that, I still am able to transcode with plex via Kubernetes and run ollama via the vGPUs in KubeVirt And validated that it was using the vGPUs. Pics below to confirm.

Meteor Lake supports GPU SR-IOV. I'm running it on Bee-Link GTi14s right now. However, i915's start is as you mentioned, not graceful.

Interesting... Could you please make a test with Windows 10 or 11?

celesrenata · 2024-10-16T15:04:26Z

Way ahead of you, I'm still fighting to get it to work.

I've got QEMU to report the PCI card from 0000:02.00
I got all the settings that intel drivers expect and then some in there
But I'm up against error 43, you can restart the device and it claims it works, but I'm still fighting that.

As for successes, I have Ubuntu 24 successfully running LLM tasks, as well as transcoding jobs from pods.
I am working on Arch and NixOS configs to run inside the VM to give linux headless features to the project next.

My work towards making everythign work lives here: https://github.com/celesrenata/nixos-k3s-configs

You can explore the settings required from this thread I am on for windows 11, windows 10 should already work, but I haven't tested it since it is so close to EOL: kubevirt/kubevirt#11338 (comment)

So you think the problem is that the PCI card is reported on the wrong address? Do I understand right? As I could see in your kubevirt link you overwrite the address so that it gets reported on 0000:02.00. Why do you think it‘ll work on Windows 10 but not on Windows 11?

jeeftor · 2024-10-16T22:33:24Z

This is your intel config?

https://github.com/celesrenata/nixos-k3s-configs/blob/main/nixos-kube-configs/gremlin-1/overlays/i915-sriov-dkms.nix

Your Nix skill is impressive ... i always get my head so confused with nix :) (even though I'm using nix-darwin on most of my macs)

I'll spin up windows 10 to verify this weekend.

https://github.com/celesrenata/nixos-k3s-configs/blob/main/nixos-kube-configs/gremlin-1/overlays/i915-sriov-dkms.nix is the main module from this repo I import.
https://github.com/celesrenata/nixos-k3s-configs/blob/main/nixos-kube-configs/gremlin-1/overlays/intel-gfx-sriov.nix I borrow from the original intel sr-iov project to create the VFs
https://github.com/celesrenata/nixos-k3s-configs/blob/main/nixos-kube-configs/gremlin-1/overlays/intel-firmware.nix to hunt down the specific firmware files.
and to add the custom kernel config values before compiling. https://github.com/celesrenata/nixos-k3s-configs/blob/main/nixos-kube-configs/gremlin-1/overlays/kernel.nix

Nope, win10 also fails.

What makes you think that the driver fully supports sriov for meteor lake?

ccoles146 · 2024-10-22T09:54:47Z

This is what Intel says: https://dgpu-docs.intel.com/driver/kernel-driver-types.html

The following features are only available in the out-of-tree i915 kernel module:
-GPU debugging
-Single Root I/O Virtualization (SR-IOV)
-Virtual Memory Binding (VM_BIND) and Ultra Low Latency Submission (ULLS)

Although I tried to get it working with the Xe drivers, it seems it is not supported. So far I haven't got the dkms driver working either.

celesrenata · 2024-10-26T08:08:31Z

What makes you think that the driver fully supports sriov for meteor lake?

I thought I'd give it a try as I am consistently able to get LLMs via SR-IOV running in parallel in Ubuntu 24.04 KubeVirts with this driver.

celesrenata · 2024-12-11T23:08:49Z

https://lore.kernel.org/lkml/CAPM=9txbfH8vf-YjwTXEYL729a6r2eeLBxCJc3MSD-t5jXVA-w@mail.gmail.com/ looks like 6.13 has some sriov work, we might see it then.
