MS-A2 Minisforum (AMD Ryzen™ 9 9955HX + Radeon™ 610M) – The “I Finally Stopped Crying” Zero-Artifact iGPU Passthrough Thread

[CAAD]

Unfortunately, I was able to use the igpu for some gameplay, emulation and other graphical uses. The 610m indeed is inadequate and artifacts everywhere to a point where it heavily distorts the picture. Ill look at some dgpu options and will go for nvidia gpu to see how it goes.

my old dell dimension with a 4790-i7 and nvidia 2070 super beats the pants off the quality but cannot run pve for anything.

I only provided settings to remove Code 43, so it likely won't function properly on its own.

* Your configuration does not meet the prerequisites for implementing the steps he outlined (such as blacklisting amdgpu and gop not being set), so I commented to point that out.
In your current state, you have just reached the starting point to implement the configuration he presented.

Artifacts won't disappear unless the BIOS and other settings are adjusted to match the specific requirements for that model.

Since I don't own that model, you should follow the steps provided by the person who has the device.

He polished it to near-perfect condition, so his procedure should be followed.

Oh, once I removed the blacklist for amdgpu my GPU appears in the Windows VM!
I believe now we have a proven way to get the igpu to work in Proxmox 9.1.0 on the Minisforum MS-A2 with 9955HX CPU and 610M iGPU.

A side note, the AMD Adrenaline driver app will give a "Oops error 195" when the app doesnt detect the igpu 610M.

As you can see I have that as well. I would like to get ASPM working as I have had it function without the VFIO values. This allowed me to have ASPM and the artifacts made that really difficult to debug as I have PFsense hosting my entire home network/hotspots etc. Rebooting pve meant I had to take down the network. I am running a PFsense / Ubuntu / Windows 11 ; MS - A2, with no need to restart pve. I mentioned almost everything I can think of from : BIOS , to Tools and Utilities to make working with this more accessible while the system is unstable, and the values from pretty much every table possible.

Also I hope when people here do find better settings (with this exact hardware I might add) ; that they are proud enough to share them here. To me this is the whole point of a community like this.

Well theres some other reasons I need a stronger GPU but this was good enough for me to evaluate the 610M.
@ozumo thank you very much for all your assist. THe suggestions here are indeed insightful.
@futiless Thank you as well for posting your settings.

Anyone else using the MS-A2 with 9955HX specifically, lets share our settings!
