If anyone else follows this thread, could they please post the exact make and model of whatever (minipc?) device that they have successfully applied iGPU passthrough to?
I've got a Minisforum HM90 (AMD) and have had no luck, trying every few months after a PVE update. I figure if "we" compare notes on various hardware combinations, then "we" might be able to cobble together one or more reliable iGPU passthrough guides.

@Xclsd Thanks for the heads-up on that beast of a mobo working with Ubuntu. I actually want to use a linux desktop myself, so that is encouraging. I have been mainly testing with a Win10 image because I thought that would be the most likely to work. I will go through the procedure again with an early Ubuntu 24.04 mantic desktop on my HM90 Minisforum and see how I go, and report back.

I read on another thread that the issue with the driver is also affecting other users using the UHD 770 driver: https://forum.proxmox.com/threads/i...passthrough-the-dreaded-code-43-error.113229/
I tried it on Win10 too. If I get a chance, I will try Win11, just in case it is a version specific problem.

Interesting, I've never managed to get any kind of GPU passthrough to work to even know what SRIOV has to offer. I googled it and found this page which lists a few NUC models that could be potential iGPU passthrough hardware targets... I obviously have a lot to learn.

FWIW my use case is to run my main daily driver desktop (Manjaro/KDE) in a VM on a mid to high end miniPC (hence the need for iGPU passthrough) so I can take advantage of effortless back-ups to my Proxmox Backup Server, and a trouble free bootable ZFS file system. I could handle a 5% performance hit from a VM, but SPICE gfx, for instance, is just not good enough for all day desktop usage.

Well, it depends on what you want to achieve: For desktop usage a VM with SPICE is enough for my need. But if you need accelerated GPUs for some reason, you might end up needing GVT-G, SRIOV or GPU passthrough. GVT-G worked somehow for me in testing scenarios.
Hello,
I'm thinking about the nuc13 (raptor lake 13th gen with iris xe). There ale a lot of posts about the poblems with the full igpu passthrough to windows VM. Two questions:
- is linux VM (e.g. ubuntu) simply working for such setup, so I did not find similar posts?
- does the full igpu passthrough give the full hdmi audio/video output beside the gpu access, and so the VM can be used as a desktop on external monitor? Maybe it's so obvious, but the posts I found cover windows VM only in relation to similar doubts.

It should be working. You don't need too passthrough anything to use a VM. You would just have to use a virtua GPU then.
IF the passthrough is possible (I don't know if it is): Linux will just work, if mesa / kernel is as new as needed for the GPU.
IF SR/IOV is working(I don't know if it is):: Linux will just work as well.
IF the passthrough is possible (I don't know if it is): You can use HDMI + Audio output as a usual Desktop. You'll just need to power on the device somehow via the Interface / a Script / whatever solution is possible to power on the VM.
I can confirm, AV over HDMI works well with the full gpu passtrhough for NUC13 i7 with linux VM.
