This is a guide to get the Ryzen 7 7735HS with integrated graphics running with proxmox inside a Windows VM.

Proxmox v7.4/v8 - Ryzen 7 7735HS - AMD Radeon 680M GPU passthrough
So just cheked and the only thing that I didn't do was set the PCI passthrough to primary GPU, use of the proxmox helper scripts for the after install stuff and microcontrol processor update.
After installing ffmpeg and Radeontop, I can say that hardware accel using VAAPI works.
Managed to get it working on Proxmox VE8 simply following this tutorial there. I don't know why it didn't work before. I only managed to get a remote desktop using the GPU on Windows 10. Ubuntu still crashes, not sure why.
In win10, it seems like the reset issue is gone, I can stop and start the machine as many times I want and the GPU works properly every time without crashing the host. All I can say is: use the latest versions for proxmox and the kernel etc

Nice!
Just a quick question, why add the fllowing ?
echo "softdep radeon pre: vfio-pci" >> /etc/modprobe.d/vfio.conf
echo "softdep amdgpu pre: vfio-pci" >> /etc/modprobe.d/vfio.conf
echo "softdep snd_hda_intel pre: vfio-pci" >> /etc/modprobe.d/vfio.conf
Btw the vendor reset stuff isn't necessary right? Since it doesn't work in the first place
The addition helps with the GPU reset issue, it makes vfio-pci handle the drivers in a more stable way. It seems like the changes in `pve-blacklist.conf` are not needed in VE8, only config goes inside `vfio.conf`.
And no, the "vendor-reset" module on the host doesn't seem to do anything BUT the RadeonResetBugFix seems to make a difference, no idea why.
@Matssa56 Need your help :) I think I managed to isolate the specific problem that prevents Win11 from working!!!
Hey @Matssa56 what device do you have? do you mind sharing your vbios with me pls? [email protected]
I discovered that the problem seems to be when using OVMF (UEFI) for the BIOS type.
I created 2 identical VMs with Win10, 1 with SeaBIOS and the other with OVMF (UEFI). The UEFI one throws Error code 43 when trying to initialize the GPU and the seabios works properly. I'm wondering if the specific vbios I extracted from my system doesnt have UEFI support and maybe the vbios from someone else with a different motherboard works.
Please I'm out of ideas :)
FAILS: OVMF (UEFI)
WORKS: SEABIOS

I think I have the same device as you : minisforum UM773 lite so not really sure my vbios will be different. My Linux machine is using seabios, not the other one. Why not stick with seabios?
oh damn, did you install the latest BIOS when you got the UM773 Lite? IDK
it might be nice to try if we get a different file, it's possible depending
on the BIOS version and settings.
Sadly, UEFI is critical for windows 11 and other modern OS like Ubuntu if
you want advanced features.
If we could find someone with a different machine but same processor (maybe
a SER6 PRO for example) and compare the vbios we can find exactly why UEFI
isn't working on the MinisForum BIOS.

Yep updated the bios but it was already up to date when I received it.
Did you try the minisforum discord? I hope someone can help there :-S
You can maybe try ESXi from VMware, maybe you'll have better results?
What CPU did you use in the VM? Host?
I didn't update the BIOS so maybe that's the reason. It's a pity that I
can't update the BIOS without running windows since it's an exe :(
I still think that trying your up-to-date vbios might work for UEFI stuff.
I used "host" for the CPU and the same config as in the guide for both (see
pictures).
The only difference between them is the BIOS type :O
Hello Everyone,
I have followed "https://github.com/isc30/UM773-Lite-Proxmox/tree/main" (thanks for tutorial), but when i stop or restart my VM using GPU passtrought (780m), i cannot start again my VM agains (error : timeout waiting on systemd), i need to restart the host.
Proxmox : 8.2.4
Linux 6.8.8-2-pve
VM Win11, UEFI, VGA none.
I use radeonresetbug without any change.
Without this case, all working fine (External monitor, no Error 43)

I got the same issue! when i try to restart windows 11 vm: timeout wating on systemd.
cpu: 8845hs
pve: 8.2
vm: windows 11

Well nothing in particular except the microcode update using the proxmox helper scripts. Plus I didn't put "use as primary gpu" in my memory, I'll have to take a look to be sure.
Do you have the latest bios?
