I also had that problem with 6.8.12-2.
I had to pin 6.8.12-1 and everything worked.

proxmox-boot-tool kernel pin 6.8.12-1-pve

[admarty]

I don't think your iGPU (GeminiLake UHD Graphics 600) supports SR-IOV.

I also had that problem with 6.8.12-2.

tried proxmox-boot-tool kernel pin 6.8.12-1-pve, the pve failed to boot...

[crospa91]

6.8.12-2 as well here and even if the whole procedure complete, I can't see the 7 functions.

Don't have the option to revert or pin older kernels.

[pasbec]

Only 12th, 13th and 14th Gen GPUs support SR-IOV. Gemini Lake is 9th Gen from 2017 and thus too old.

AlderLake and RaptorLake are both working and I have both of them up and running with 7 VFs with the latest 6.8.12-2-pve kernel.

Your cpu is also j4215 ? how to do this.
I tried 6.8.12-1-pve, but system start show is 6.8.12-2-pve too.

[pasbec]

With J4215 you shoud check for a GVT-g guide, not SR-IOV! It is Intels previous GPU virtualization technology.

[yduanBioinfo]

My host version is 6.8.12-2-pve, and my CPU is intel N100. I suppose I made it.

By the way, I failed at the first try because I hadn't run "update-grub".

[pasbec]

You could get rid of the firmware mismatch but the mmio remains. But the VFs seem to work despite the error messages. Just ignore the errors. Got the same output on my N100 and VFs are working fine with 3D and video accelleration in Windows RDP. My N100 host is up and running for 60 days without issues.

[purefalse]

I encountered the same problem
But I want to share the graphics card function to OMV VM hard decoding HEVC
But when starting OMV VM i915 crashes on boot

Video card captured in OMV
But there is no such thing in /dev/dri

Is there any solution to this?

[pasbec]

Have you installed the drivers in omv aswell?

Actually, I have the same demand as you. However, I'm still trying to make VF work in OMV VM guest. Now I'm stuck in the "make deb-pkg" step, It's hard.

I never thought about installing the driver Because I directly pass through the graphics card omv it can be caught but i will try i just think omv It should also be able to capture my sliced ​​graphics card. But it seems it can't And although the slicing is successful in pve But i915 reports that it has an error But I saw that everyone in win10 can directly ignore the error and output successfully. That's why I want to ask if I did something wrong somewhere

[yduanBioinfo]

@purefalse According to the README of this Driver, Linux platform geust should also install this driver to enable VF pass through. While on the Windows platform the driver can be installed smoothly since it have already supported the intel VF driver (I guess).

[Zackptg5]

I got it working on 6.8.12-2-pve but I had to essentially reinstall i915 kernel module:

rm -rf /usr/src/i915-sriov-dkms-*
rm -rf /var/lib/dkms/i915-sriov-dkms
find /lib/modules -regex ".*/updates/dkms/i915.ko" -delete
cd ~/i915-sriov-dkms
git pull
dkms add .
dkms install -m i915-sriov-dkms -v $(cat VERSION) --force
update-initramfs -u -k all

[yduanBioinfo]

@purefalse I built an Ubuntu VM server on my PVE host. After installing i915 driver inside the VM machine, the VF worked, and hardware transcoding was successfully enabled.

[purefalse]

I't OK.
But not working.

I don't know what else to try

Only lxc jellyfin remains

[purefalse]

Later I installed the OMV plug-in
Replace PVE core
After installing the i915 driver it seems OK
To be tested

[purefalse]

Although /dev/dir is read
But there is no function
I don’t know if there is any solution
