So, if VM1010 is using the VBIOS of the GPU, please also provide the configuration of that VM. Otherwise, it won’t be useful.

Please modify the file /etc/modules to the following lines:

done


Then you need to post the VM configuration where you want to set up the passthrough.

I don't get how can i run this. For the windows VM, the console shows Windows, there is no shell to run the command
 
Okay... I still don't get where you want to set up your passthrough.

Windows 10?
Linux?

I need the config from the VM you want to passthrough.
Use the following command:

Code: 
cat /etc/pve/qemu-server/{Your VM ID}

In `/etc/modprobe.d/pve-blacklist.conf`, you have

blacklist amdgpu
blacklist snd_hda_intel

listed six times. Remove all duplicates and keep only one entry each:

Code: 
blacklist amdgpu  
blacklist snd_hda_intel

Then, ensure that your VM configuration file `/etc/pve/qemu-server/{Your VM ID}` contains the following lines:
(You need to adjust these values to match your hardware and VM configuration.)

Code: 
hostpci0: 0000:05:00.0,romfile=vbios_5825U.bin,x-vga=1  
hostpci1: 0000:05:00.1,romfile=AMDGopDriver-5825U.rom

After making these changes, restart your system.

Your `lspci -nnk` output:
`Kernel driver in use: vfio-pci`
looks good.

I think the only problem is the `pve-blacklist.conf` and the `/etc/pve/qemu-server/{Your VM ID}` file not having the correct BIOS.

After this, everything should work fine.

I think you want to passthrough the AGPU to Linux because you wrote:
ls /dev/dri/
ls: cannot access '/dev/dri/': No such file or directory

That is not a Windows command; it's a Linux command.

So, to be clear, do you want to set this up in Windows or Linux?

Only show the config from the VM you want to passthrough...

PS: i will send you a PM
 
I hastily created an issue in the github repo, maybe i should have posted here first. I have everything working, but no output on HDMI - so close I can taste it.

I don’t have an external monitor, so unfortunately I can’t test it myself—sorry!

From what I’ve seen in other forums, VGA output should be set to:
none

As for my system, I don’t have the following files on the host:

Code: 
/etc/modprobe.d/blacklist.conf 

/etc/modprobe.d/kvm.conf

Output of ls -l /etc/modprobe.d/
Code: 
-rw-r--r-- 1 root root 154 Aug 22  2024 amd64-microcode-blacklist.conf

-rw-r--r-- 1 root root 127 Jul 12  2023 dkms.conf

-rw-r--r-- 1 root root 214 Jan 28 10:46 pve-blacklist.conf

-rw-r--r-- 1 root root 148 Jan 28 10:03 vfio.conf


Contents of /etc/modprobe.d/pve-blacklist.conf:
Code: 
blacklist amdgpu

blacklist snd_hda_intel


I believe it doesn’t really matter which .conf file the blacklist entries are placed in—it should work the same either way.

.....

sorry can not help you more
