edk2 VS gpu-passthrough-tutorial

OVMF: edk2-stable202302 patched with ACRN patch (https://github.com/johnmave126/edk2/tree/intel-gop-patch, also see https://github.com/Kethen/edk2)

Can't use Kethen/edk2 because my BIOS update has no IntelGopDriver (it doesn't even have IntelGopVbt but rather IntelGopVbt2)

I wanted to share some tips on how to get this working. The repo below allows you to build an OVMF bios which allows a UEFI virtual machine to work with display output when using Intel integrated graphics: https://github.com/Kethen/edk2

I used my laptop BIOS file from which I extracted the efi IntelGopDriver and vbt files (note that it seems to have two vbt in BIOS file), I used the same one I found in "/sys/kernel/debug/dri/0/i915_vbt", then I recompiled OVMF with this files using https://github.com/Kethen/edk2.

For Haswell, IGD/GVT-d is possible. Use -machine pc (i440fx) + Kethen/edk2 + vbios_gvt_uefi.rom + x-igd-gms=2. You might be able to get -machine q35 + to work but without boot display. Look for a single GPU passthrough script.

Try Kethen/edk2.

I was able to get laptop display output to work via i440fx (machine) + Kethen/edk2's OVMF (UEFI) + vbios_gvt_uefi.rom (romfile) + x-igd-gms=2 (2 * 32MB graphics memory). I think you might need to also use CPU host passthrough but I'm not sure.

I got i440fx with boot display + OS display to work using Kethen's edk2 + vbios_gvt_uefi.rom

Check https://github.com/bryansteiner/gpu-passthrough-tutorial. It looks like a well-written and comprehensive guide to set up GPU passthrough with KVM (Pop-OS specific). If you have spare external hard drives, just backup your OS through Clonezilla/Rescuezilla so that you can restore the OS if it breaks.

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

So bad news I followed this guide completely without luck I tried passing through my 5500 xt and it just shows a black screen and it also makes my main display which is using my Intel arc a770 gray as well

Hi, I've been trying to pass a AMD Radeon 6700 (non XT) to a Windows 10 VM following this guide. First of all, I haven't been able to get any output signal after turning the VM on, but also don't get a video signal after the VM stops and is supposed to reattach to the host. Trying to start the VM again yields a "Unknown PCI header type '127'" error. I have heard about the AMD reset bug, but I thought the issue was fixed with 6000 series cards.

Looks like your missing some optimizations such as hyperv enhancements and cpu pinning among others. Mine was quite laggy prior to the changes outlined Here

I am running Windows successfully with passing my Nvidia GPU to it. The setup was pretty easy and without any large issues. Hooked the GPU into the system using this tutorial and installed the drivers. It works nice with a monitor connected. It also works well with Looking Glass and games also run as expected.

I just stumbled upon a guide by Brainstenier on Github that explains how to use hook scripts to dynamically bind devices (GPU, SSD, etc.) to the Windows VM before launching it, and unbind them after shutting done the VM.

I used steps from [Bryan's tutorial](https://github.com/bryansteiner/gpu-passthrough-tutorial) and this OpenSUSE wiki page for setting up my VM.

I tried following https://github.com/bryansteiner/gpu-passthrough-tutorial but I couldn't get it to work. It would stall when the hook script fired to unbind the GPU. I scrapped it and am going to start over.
