Hi guys, I'm trying to passthrough the iGPU to Windows VM
I followed many steps but there was still error 43 in Windows, please help
My promox hardware:
8700G
64GB G.Skill X5 Flare
Mainboard B650 Gigabyte Aorus Elite AX ver 1.3
1 HDD 16TB + 2 SSD 1TB
My /etc/default/grub

Hi,

How did you access the vBIOS, could you provide yours. I'm using a GMKTec K6 with a Phoenix1 and can't find the vBIOS from the BIOS.

Thanks !
 
I've reached about the same point as you have there on the Aoostar WTR Max (8845hs Pro) with 780M). I have managed to get the VM guest rebooting now without having to reboot the host. but I've tried every guide which I can find without solving the error 43.

DerekG,
Do you mean you got the passthrough to work with the Aoostar WTR Max (8845hs Pro) with 780M?
Can you share what you did to get it working as I'm really stuck and would like to have passthrough to windows of the 780M Aoostar WTR Max

Hi mrmrv,

I have managed to get the passthrough working in Windows 11 by following a combination of 3 different guides:

Note: I have not tested with a physical monitor connected as I only access via RDP. And I do have a dummy monitor dongle plugged in but I don't know if it's required or not.

It's the most complexed passthrough I've done thus far as you need to do the following:
1) Configure a the passthrough with the rom files (in my case I used both the the video and the audio rom files)
2) Configure a fix for the AMD reset bug within the guest VM (I used the DevCon.exe to reset the 780m on VM shutdown)
3) Configure for the AMD reset bug on the Proxmox host (I used the hook script method).

These are the guides I used:

For the basic passthrough, including the rom files.
https://github.com/isc30/ryzen-gpu-passthrough-proxmox

This one explains the AMD reset bug, with 2 methods to overcome the problem.
https://github.com/xiongyw/docs/blo...rum-um880pro/pve-8.4-1_minisforum-um880pro.md

This is specifically for the AMD reset bug on the Proxmox host side.
https://github.com/isc30/ryzen-gpu-passthrough-proxmox/issues/131

I hope that helps, it's too late now, but I can post my config later if needed.

Good luck.

If you can post your config that would be really appreciated.

Did you do any changes in the bios settings? Or they are the ' factory default settings'

As far as I see I did all the steps in the 3 posts, including creating a rom dump and trying the rom dump from https://github.com/isc30/ryzen-gpu-passthrough-proxmox

For me it keeps failing with

Code: 
error writing '1' to '/sys/bus/pci/devices/0000:01:00.0/reset': Inappropriate ioctl for device
failed to reset PCI device '0000:01:00.0', but trying to continue as not all devices need a reset

stopping swtpm instance (pid 3499) due to QEMU startup error
start failed: QEMU exited with code 1

in proxmox dmesg I see:
432.577260] vfio-pci 0000:01:00.0: Firmware has requested this device have a 1:1 IOMMU mapping, rejecting configuring the device without a 1:1 mapping. Contact your platform vendor.
 
What stage are you up to there.?

The passthrough should work regardless of the AMD reset bug, which shows the issue when you restart or shutdown the guest either from the host side or the guest side. If the system gets into that 'igpu stuck on reset' you can ONLY recover by a complete host reboot.

Have you got the passthough working at all?
 
PCI passthrough of the SATA controller (to another vm) goes without any issues.

GPU passthrough not at all. I keep getting the failed to setup container for group 25: Failed to set group container: Invalid argument

Without passthrough the windows vm works fine, but with passthrough it errors.
This is after reboot, so no chance yet even to get into windows. At this point I would be happy if it works once, I could live with always needing a reboot

I'm looking at those errors and it seems like you have a typo in one of your commands somewhere.
Verify that you do not have memory ballooning set on the VM.
Or maybe the vga rom file is not correct. The correct files can be downloaded from the guide you have been following.
I'm using the Aoostar Gem12 roms - AMDGopDriver_8845hs.rom (for audio) & vbios_8845hs.dat (for the igpu)

If you post all the configs as per the 1st two posts in this thread I can compare and let you know if there is anything different, but the posts above also look correct apart from the fact that all references to the igpu will be different, above is 11:00 whereas yours is 01:00

I hope @vinnfts doesn't mind, it looks like we've hijacted his thread.

Million tries further, but still no luck.
I remain getting the

note
1) I I just past the gpu, the error is the same
2) I have pci passthrough working fine for sata
3) My best guess it is related to the bios settings
 
I have the 780m iGPU passed through to a Windows VM and fully functional.

I followed the guides I posted earlier and the passthrough works so long as the correct rom files are used.

But since then I upgraded from Proxmox 8.4 to 9.0 and I noticed that the upgrade kept the Linux kernel on 'Linux 6.8.12-14-pve' instead of 'Linux 6.14.11-2-pve' which the other nodes in my cluster have been upgraded to.

I have not attempted the kernel upgrade, because it borked one of my Intel iGPU nodes, something which has been working for years suddenly I get Error 43 in Windows and even reverting the kernel version does not solve the problem. The strange thing is that I have another intel iGPU and for that unit the passthrough is still fine after upgrade.

It's worth looking into the kernel because there is a known PCI reset issue with the latest kernel version - read the last 3 posts:

Thread '[SOLVED] Proxmox 8.3.5 / Kernel 6.11.11-1: Unable to passthrough AMD iGPU (Ryzen 7 9800X3D / Granite Ridge) on X870E mobo'

Hello all,

i am getting a little frustrated trying the passthrough the iGPU of my Ryzen 7 9800X3D to one of my VM's.

Kernel (pve-headers installed): Linux deb 6.11.11-1-pve #1 SMP PREEMPT_DYNAMIC PMX 6.11.11-1 (2025-01-17T15:44Z) x86_64 GNU/Linux
Processor: AMD Ryzen 7 9800X3D
Mainboard: Gigabyte X870E

Both devices are separated in its own iommugroup which has no other devices in it, so no conflicts. I have no problem passing through dedicated GPUs (Nvidia and AMD).

VM configuration:
agent: 1
args: -cpu 'host,-hypervisor,kvm=off'
bios: ovmf
boot...
 
Finally success here as well..
I messed up and needed to do a full reset of the bios.
With the recovery of the standard values and once more entering the few options it started working.

Don't know what bios setting blocked the working, but it solved the

[ 21.315157] vfio-pci 0000:01:00.0: Firmware has requested this device have a 1:1 IOMMU mapping, rejecting configuring the device without a 1:1 mapping. Contact your platform vendor.
 
Hold on a second. Could you at least give me the settings?
I'm struggling at 780m...

Please give me the results of the following command:

Code: 
cat /etc/kernel/cmdline
cat /etc/default/grub
cat /etc/modules
cat /etc/modprobe.d/*
cat /var/lib/vz/snippets/*
cat /etc/pve/qemu-server/VMID.conf
uname -a

I managed to configure all the other integrated GPUs, but the 8700G just won't work no matter what I try, and I'm utterly devastated.

Yes, sure here we go.
NB, followed the exact instructions from https://github.com/isc30/ryzen-gpu-passthrough-proxmox
But, only after the bios reset my Aoostar WRT MAX started to work. Before I could not get it to work, the VM's crash on startup.

I'll make some screenshots of the bios settings I changed from default.
Note, I don't think my issue was very kernel related. It works both on proxmox 8.4 as well as proxmox 9.1 with most recent kernel
The only change was the bios. I can't tell my previous setting... was trying everything to get it going. I know what changes |I made from the 'load optimal settings' default.

The critical ones I changed disable: above4G decoding, resize BAR support & SR-IOV
i did not load the soundcard bios, it PVE crashes with that enabled
I had difficulties loading the grapical windows drivers, they complained about the chipset not being correct. I ended up with loading the older version of the drivers (from dec 2024)

Note:
To get Ollama working properly I needed to change the video memory to 8 or 16G

Thank you.

It's working except that it won't restart, but I was having trouble because it kept turning into a green screen when I tried to restart it.

I'll try implementing your settings.
 
For me windows restart is working fine. (assuming it goes via the proxmox restart, had mixed results with rebooting via windows inside the vm)

In some instances rebooting proxmox is hanging though. It is not consistent, mostly when I used the gpu in both Linux and windows.

It consistently hangs when using it in (in Linux) with Ollama and try to load too much in memory.
The AMD ROCm driver is not officially supporting this gpu, maybe that causes that problem.
