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
Code: 
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet iommu=pt"
GRUB_CMDLINE_LINUX=""

dmesg | grep -e DMAR -e IOMMU
Code: 
[    0.464252] pci 0000:00:00.2: AMD-Vi: IOMMU performance counters supported
[    0.611337] perf/amd_iommu: Detected AMD IOMMU #0 (2 banks, 4 counters/bank).

I checked
lspci -nn | grep -e 'AMD/ATI'
Code: 
11:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Phoenix1 [1002:15bf] (rev 06)

My /etc/modules
Code: 
vfio
vfio_iommu_type1
vfio_pci

Next, I bind the iGPU’s PCI ID to vfio-pci
/etc/modprobe.d/vfio.conf
Code: 
options vfio-pci ids=1002:15bf,1002:1640,1022:15c7,1022:15b9,1022:15ba,1022:15e2,1022:15e3

I also extracted and configured vbios
My /etc/pve/qemu-server/101.conf

I also disabled Above 4G decoding & Re-size Bar Support in BIOS

To make sure, I also blacklisted drivers at /etc/modprobe.d/blacklist.conf
Code: 
blacklist nouveau
blacklist nvidia*
blacklist radeon
blacklist amdgpu
blacklist snd_hda_intel
#!/bin/bash
shopt -s nullglob
for g in $(find /sys/kernel/iommu_groups/* -maxdepth 0 -type d | sort -V);>
echo "IOMMU Group ${g##*/}:"
for d in $g/devices/*; do
echo -e "\t$(lspci -D -nns ${d##*/}"
done;
done;

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
swtpm_setup: Not overwriting existing state file.
kvm: -device vfio-pci,host=0000:01:00.0,id=hostpci0,bus=ich9-pcie-port-1,addr=0x0,romfile=/usr/share/kvm/vbios_1002_1900.bin: vfio 0000:01:00.0: failed to setup container for group 25: Failed to set group container: Invalid argument
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.
