So, is there any conclusion on this?

 

I can't get it to work, and I'm honestly not in the mood to try 15 different posts with hundres of XML lines.

 

I'm on a MSI B550M PRO-VDH WIFI.
I can get the VM to detect the iGPU, but I keep getting Error 34 in the device manager. The driver won't work.

Did anyone ever get this definitively working? I've spent probably a week of my life off and on trying to get the same accomplished with a 4600G. I have the VBIOs, followed every guide imaginable, and despite having zero errors I can get two variations of result. Either no signal to my monitor, or signal with no image. Frustrating. I think I'm calling it quits.

the igpu yes, but requires some grub edits to stop the FB. and sometimes a modprobe vfio edit.
I recommend 6.12.10 now due to CVE and changes /evolutions in the linux kernel.

Please review documentation in antoehr forum:

Quick question: Is this kind of GPU passthrough only for those that want to game with the VM and/or want to attach a display to their Server and get VM GPU output? Or can I accelerate graphics on my Windows VM as well? I do feel like it's a bit slow and sluggish with just the emulated Redhat graphics...

Yes  it just on the cpu and not on you 

graphics card

This might be a newbie question..., but here it goes, hope someone can help me understand this, after going through this thread I was able to extract my Ryzen 5 5600g's iGPU vbios using UBU, but maybe I missed something, the file is a .dat file, but unraid uses a .rom file, is there a tool or something to convert the .dat to a .rom?

UBU ? That I did it long time ago  I use gpuz after  boot with a second  gpu see site 2

Just rename it, no conversion necessary.

@tola5 I tried using gpuz, but it didn't let me, saying that it was not possible to get the vbios for it, that's why I had to use UBU. I've previously used gpuz for other dGPU without an issue, but with this iGPU it's giving me issues.

 

@kurai Awesome, thank you! Let me give it a try!

Have someone the Solution?? Have Minisforum HX90 with AMD Ryzen 9 5900HX with iGPU. iGPU is on, IMMO is ON.

Im here 3 days but no luck. Hope someone can help

So I finally have this working:

• UnRAID 7.2.0

• 5700g

• MSI B450 Mortar (latest beta BIOS)

• Extracted VBIOS using UBU (vbios_1638.rom)

• VM:

  • SeaBIOS

  • i440fx 9.2

  • VNC as primary GPU (can't be removed)

  • iGPU and it's audio controller als separate devices (no multifunction)

  • OS: Pop!OS (for now.)

Everything works.

...except for resetting the GPU. Any tips on how to take this last hurdle?
