Intel UHD630 iGPU - PCIe Passthrough to Windows 11 Guest

[SeeGee]

I've been bashing my head against the wall with this one for days now.

I have a Dell Optiplex 3070 SFF:
i5-9500 (Intel UHD 630 Integrated GPU)
8G RAM (To be upgraded if i can get this to work)
512G SSD

System boots using UEFI, VT-d enabled

I started off using this guide: https://3os.org/infrastructure/proxmox/gpu-passthrough/igpu-passthrough-to-vm/

I am having no success getting this to work. It seems like others have been able to achieve this, but for some reason I seem to be unable.
Any suggestions would be appreciated...

Here is a port of someone who got UHD730 working but also contains notes about UHD630: https://forum.proxmox.com/threads/n...strough-works-igpu-linux-radeon-win11.136444/

I did tried that last night, no success :-( i gave up with a pass through on that intel630 and installed an asus gtx 1650 oc i had lying arround, everything isnworking flawlessly now

 

[jpa19]

I'm having similar issues on an Optiplex 3070 minipc, I manage to achieve passthrough (the guest sees the igpu uhd630 and can "do stuff" with it), but can't get screen output on an actual hdmi connected screen at all. I get black screen, I can drag windows onto it (because it's "next" to the VNC display) but the screen just won't turn on.
Has someone actually got display output from igpu passthrough? Is this some weird Dell issue?

 

[SeeGee]

I didn't even get that far. I can get the vm to see the iGPU in device manager, just can't get any actual output... Windows shows two monitors, but dragging a window to the non-vnc screen doesn't show anything. Just black.

syslog Just curious how do you get syslog info ?

I also have a optiplex uh 5050 with the i5 7500 and UHD 630 and I got it working uh in remote desktop and it shows the uh I630 driver but with remote desktop it blanks out the screen resolutions and displays I thought maybe I can go there and switch the display but Nope well I did get both endeavor Linux the newest 2024 which is arch and the newest MX Linux which is Debian working flawlessly through the pass through so I was saying well windows has more notoriety joking aside and I can get it only to work through Microsoft remote desktop well at least an image of the operating system I'm not sure if the passthrough is working but audio visual work way better than without the pass through but that's not the problem I guess I tried to gain access to the IGPU630 ROM using CPU Z but of course it's blanked out actually went on the proxmox system installed windows and uh ran that program and it's blanked out I ran the same program within the Microsoft remote desktop still blanked out as per the above inquiry I basically have the same set up right out of the textbook so the Linux stuff is working great but I want the windows 11 pro to too work So anyone know how to download the 630 ROM so I can attach it in the ISO area of proxmox? And I'll be on top of this until I get it done and I'm not gonna switch to a video card. Just a little tip if you don't know already um you can do voice texting by pressing the windows key and H, I don't type anymore when I'm doing text so if you're interested in that maybe a little tip in the windows 11 pro environment anyways I' I'll report back with more information I don't see this being closed but I'm just an old guy smiles ohh yeah I don't consider the pass through working if it doesn't go to the proxmox monitor so something working in Microsoft RDC I don't consider working even though it has it's advantages I want Microsoft Windows 11 pro to run like the linux operating systems and by the way I just added PCI audio made the adjustments to the audio and both Linux systems run flawlessly and I even uh set up additional networking using another PCI pass through and that worked and blew my mind so anyways I'm like everyone else I wanna get windows 11 working with the I630 I'm thinking maybe because it has 3 video outputs that maybe you have to preprogram that somehow to go to the HDMI rather than the two other display ports I haven't checked that out I do have some HDMI DP dongles that I can use but I want to know the technology about the pass through I don't wanna be immature in a sense or a test engineer by switching out the ports no I wanted to go to the HDMI port nothing else so I was wondering if anyone knew how to set it to the HDMI port that I'm using everything for rather, than it might be outputting to the DP but again I'm having trouble with system logs anyways thanks for reading!
