single-gpu-passthrough VS i915ovmfPkg

The main guides I have used are the bryansteiner guide, the risingprismtv guide and this Ubuntu 22.04 guide.

I am following this guide to achieve Single-GPU passthrough. I am stuck at step 5, because when I run the VM for the first time to install Windows, instead it shows me a black screen with "TianoCore" when I press a key to boot the CD-ROM drive.

Not long ago I setup single GPU pass through following the instructions the risingprism wiki (https://gitlab.com/risingprismtv/single-gpu-passthrough). This all went very smoothly and works great.

Try this one by rising prisim

I just finished the coveted RisingPrism guide for Single GPU-Passthrough for a Windows 11 VM, and while I was successful for the most part, it wasn't entirely smooth.

Refer this guide https://gitlab.com/risingprismtv/single-gpu-passthrough/-/wikis/home for single gpu passthrough if ur concerned about gaming in linux

i basically followed this guide to a tee, and for some reason whenever i try booting into the VM, all i get is a black screen with my cursor. is there anything i can do to fix this?

Okay so issue, and how this all kind of ties together. I followed a siggle pass trough guide (https://gitlab.com/risingprismtv/single-gpu-passthrough/-/wikis/home) and I got the log which I replied to this comment which prompted me to do the ACS override pacth which didnt work and then I came here after I tried some other stuff. Back to the present I'm not sure how to fix this issue now (decided to restart over) , so in step 3 (IOMMU groups) It said to skip steps 8 and 9 if my devices were in 2 different groups, so i did, and now i get this.

I followed Risingprism's guide to Single GPU Passthrough. Currently though, disk usage is slow for me. The system often hangs when moving files around, and I can't move two files at the same time or else none of them get moved, I have to pause one.

While I was trying to troubleshoot the issue and reading about them on the internet I found this VBIOS for intel GPUs (https://github.com/patmagauran/i915ovmfPkg) which I proceed to use because I wasn't able to dump mine (thanks DELL for removing legacy boot).

Using the patmagauran/i915ovmfPkg VBIOS just crashes my entire system.

I came across this project and thought it was a solution to the problem. When I set the provided rom file romfile=i915ovmf.rom in the Proxmox configuration my machine hangs for a minute or two and then the host crashes completely and shuts down.

For the graphics to display output at VM start, you should research about i915ovmf.

I believe there could be some kind of "driver" like (i915ovmf)[https://github.com/patmagauran/i915ovmfPkg] but made for SeaBIOS instead of OVMF. So I would want to ask if someone knows more than me on this matter.

You need a custom vbios for Windows. MacOS will not work at all as far as I know .https://github.com/patmagauran/i915ovmfPkg

I compiled them myself using this github guide: https://github.com/patmagauran/i915ovmfPkg/wiki/Compiling

I've come across i915ovmfPkg and OSX_GVT-D but just wanted some insights if anyone has come across this issue and found a solution before I head down this path. If anyone has any ideas to help out would be greatly appreciated!
