after Upgrade to Kernel 5.13.19-1 my PCI-Passthrough (GPU) doesn't work.

Last working Kernel: 5.11.22-7

My Configuration:

Mainboard: Asrock J4105 with Intel J4105
The primary GPU (part of Intel CPU i915) is connected to a VM (the Proxmox-Server self is headless).
On the VM is a Debian Buster (Kernel 4.19).

In the Attachment are the "dmesg-Log" for both Kernel-Versions (I removed the timestamps for better compare).

I think, the problematic logs are the following lines (only present in Kernel 5.13.19-1):

DMAR: No SATC found
DMAR: IOMMU feature fl1gp_support inconsistent
DMAR: IOMMU feature pgsel_inv inconsistent
DMAR: IOMMU feature nwfs inconsistent
DMAR: IOMMU feature eafs inconsistent
DMAR: IOMMU feature prs inconsistent
DMAR: IOMMU feature nest inconsistent
DMAR: IOMMU feature mts inconsistent
DMAR: IOMMU feature sc_support inconsistent
DMAR: IOMMU feature dev_iotlb_support inconsistent

DMAR: [DMA Write] Request device [00:02.0] PASID ffffffff fault addr 0 [fault reason 02] Present bit in context entry is clear
vfio-pci 0000:00:02.0: vfio_ecap_init: hiding ecap 0x1b@0x100
vfio-pci 0000:00:02.0: IGD assignment does not support opregion v2.0 with an extended VBT region
vfio-pci 0000:00:02.0: Failed to setup Intel IGD regions
DMAR: DRHD: handling fault status reg 2
DMAR: [DMA Write] Request device [00:02.0] PASID ffffffff fault addr 0 [fault reason 02] Present bit in context entry is clear

I have no Idea ...


By the way - since the new PVE Version 7.xx the PCI-Passthrouph of a Network-Adapter has also Problems (the Hardware is not present in the VM). After some restarts of the VM it works (this VM uses a Kernel 5.10).

I can't see any problems, Graphic Card has its own group ...
The Qualcomm Atheros Wireless Network Adapter is also not "passthrouph" to the vm (other vm)

Hi @derMischka , Hello everyone

I'm relatively new to proxmox and it's my first setup. Running proxmox 7.1.1 kernel "5.13.19-2-pve" and ran into the same issue.

Hardware used : mini PC from minisforum EliteMini U850, Intel Core i5 10210U processor 4 cores 8 threads, total cache 6MB, equipped with Intel® UHD graphics (300MHz-1.10GHz). CPU speed is limited as the cooling is very primitive but it is serving as my proxmox lab rat for now.

My configuration is here below and I hope it is resolved soon.

Thanks, Kay

Same problem here.
Works Fine in pve 6.4 before with this
GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on iommu=pt net.ifnames=0 biosdevname=0"

now with pve 7.1 with kernel 5.13, block at boot, with dmar mesages from the network card not registered ( intel 10Gigabit )

if i remove intel_iommu=ob, it bot correctly but no passthrough ...

if i boot with kernel 5.4 , no problem.

FYI In 6.4, it was working with kernel 5.11.

Strange. if a i have time i try with kernel 5.15

Install the kernel ? it's ont post-it thread on the forum.

But my problem is weird, it's not a problem of kernel, but sometimes it's not working on a cold boot ( with 5.13 or 5.15). If i just reboot after, it works...

after updating the kernel, still got the same issue. UHD600..
 
Just plug in a xubuntu iso , do live session and it will give the result directly. new hardware, new kernel, and update on top of that. start with linux, have it fully work... then try windows. the error 43 and so will give you few days of reading. different pc, different config.. lot to read to have the onboard pass in win.
 
I juste move to pve 7.1 and now i am running into the same issue. Was there any solution already?
 
5.13.19-6 still have the problem ,
same problem here with UHD 750

i tried several things now, like the newer kernel, setting the relevant arg into to grub cmd line but still no success..
Any further advices what to do?
