Support for Core Ultra 7 155H - Meteor Lake #210

Open jeeftor opened 1 month ago

jeeftor commented 1 month ago

For the life of me I can't seem to get this thing to install on Kernel 6.8.12 with an 155H processor. Can somebody confirm whether its supposed to be supported at this juncture.

I haven't been able to get past this error

Following and current have vf showing up in proxmox, but haven't verified functionality. Will update in the next day or two. I have the same CPU (beelink GTi14) and doing completely fresh install.

EPiSKiNG commented 1 month ago

Here are my current steps that are allowing VFs to show up in the host from a fresh 8.2.2 install:

echo "devices/pci0000:00/0000:00:02.0/sriov_numvfs = 7" > /etc/sysfs.conf
reboot

Will continue on my progress after dinner/tomorrow.... Hopefully that gets you pointed in the right direction :)

ccoles146 commented 1 month ago

Did you make any progress with this. I'm currently trying to get an Ultra 5 working? I thought I was making progress using Ubuntu 24.10 with kernel 6.11 but it seems not.

EPiSKiNG commented 1 month ago

I wasn't able to get the VFs to work properly for the nodes. I gave up and went the LXC route for my needs. I'm sure it will get ironed out in the next couple of months, but nothing I did got me to the point where the vGPU would function properly in the VM. I'm also contemplating just doing a full passthrough to an Ubuntu 24.04 VM and running my containers inside there. Fingers crossed for full 14th gen iGPU support in the future. :)

mm2293 commented 1 month ago

You think full gpu passthrough would work? I've tried to get it working with Windows 11, but I couldn't get rid of error 43

ccoles146 commented 1 month ago

I got the same error 43.

mm2293 commented 1 month ago

I got the same error 43.

With full passthough?

ccoles146 commented 1 month ago

@mm2293 yes that's full passthrough. I've not got a VM to boot yet using SRIOV. I just installed the bbaa-bbaa branch to see if it helped with kernel 6.11 but I get errors still.

For full GPU passthrough I imagine you just need to clean install latest proxmox, spin up a VM and pass through the GPU. I don't think there's anything else to it than that? I don't even think you need to install the drivers on the host or do any other kernel/boot edits.

I had the same thought until I got the error 43 in Windows 11…

I think we have to wait for the xe driver to Support SRIOV :/

jeeftor commented 1 month ago

Are the xe drivers something attached to a kernel release - or we have to just wait on them to be written and they can be back-fit into an existing kernel?

johntdavis84 commented 1 month ago

The Xe driver is the current generation of Intel iGPU driver. It’s been in development for quite a while now, and as of Kernel 6.12 became the default in-kernel driver, replacing the i915 kernel driver.

iGPU (and A-series dGPU?) SR-IOV support was kind of shoe-horned into i915 based on the work done to get SR-IOV working in Xe, from my understanding. However, while the Xe driver should have more stable and featureful SR-IOV support than i915 going forward, the version of the Xe driver in the current 6.12 kernel does not enable SR-IOV support for iGPUs.

Given the latest dev notes, a lot of us are guessing we might not see SR-IOV enabled in Xe for iGPUs until at least 6.13.

For full GPU passthrough I imagine you just need to clean install latest proxmox, spin up a VM and pass through the GPU. I don't think there's anything else to it than that? I don't even think you need to install the drivers on the host or do any other kernel/boot edits.

Have you tried the full passthrough?

Indeed, and I managed to get it to work properly to passthrough to Ubuntu server 24.04. If I remember correctly, I installed drivers in both host and node.

Okay, hmm, what the hell is the problem with Windows then 😫

Could you please share your configs?

I am also interested how to do it exactely, which drivers to install?

EPiSKiNG commented 1 week ago

Hey guys, sorry for the delay. I think if I recall I added the kernel parameters for iommu and passthrough and then just passed it through. I don't recall doing anything special. If all else fails, using LXC passthrough works great as well. Unfortunately, I've moved on to using LXC exclusively for my use case and am not fully passing through the GPU

EPisKiNG, thanks for the response, but I'am rather a beginner in this stuff. And the server is already running different real time scripts, so I also want to minimize the testing phase...)

Add the following lines to your /etc/default/grub file: GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=o update-grub and reboot

then adding a line to de vfio.conf file (xxx:xxx is the ID that can be found with lspci -nn | grep -i vga) echo "options vfio-pci ids=xxxx:xxxx" > /etc/modprobe.d/vfio.conf update-initramfs -u reboot.

I do not need to install the intel drivers on the host?

EPiSKiNG commented 1 week ago

I believe the drivers should be installed, but if you're using modern PVE, you should already have them in the system. Technically, it shouldn't matter I don't think? Since we're passing through the GPU device in a "raw" manner rather than utilizing the vGPU functions.

Good luck!

Proxmox 8.3 released with option for 6.11 kernel. Wonder if that makes things any easier?
