I use GOTupd tool made an uefi igpu bios which can go with OVMF.
I can see desktop before driver install，but I got the same problem after driver installed.
I think GPU generat multi display layer and at final step all layers mixed together to a single screen, the mouse layer is good and the others are corrupted.May be without driver installed all image use a single same display layer as mouse.
Some other info said old driver without amd link remote display func can work at some Radeon addin card, I will try old 3400G APU.
May the new driver put the image to some new place where remote display func can read from.
Attach file is my bios.

Where can i find that "GOTupd" tool? I need a OVMF BIOS for Cezanne APU.

hi, could you share the details about your config.
I tried all what I found, but in case when seabios used the error appear: device does not support requested feature x-vga
without x-vga=on vm can boot but no video signal, and the code 43 in the device
 
OK, now i figured out how to create UEFI ROMs from Legacy BIOS.
I proudly present to you a working vBIOS for AMD Cezanne (running here on a ASUS PN52 with AMD Ryzen 5800H APU).
UEFI and SeaBIOS is working!!!

Only problem now is that on VM shutdown i get a system reset :-(

@DocMAX could you please share how you created the rom?
 
I had working setup with AMD igpu passthough and without any reason things got messed up. I cannot log to proxmox webgui, cant ping host aswell, VM's are working. How do i get access to console with all those overrides (im on ZFS, not using grub).

Forgot to mention that VM's are using passedthrough nic's and proxmox host is on mobo builtin one. I cannot review nic settings since i got no access.

You need to boot from live-cd (ubuntu as example) mount the filesystem and fix it directly.

Glad i found this topic. @RtcBoy thank you for shaing the Renoir bios. I can boot with OVMF/UEFI and BIOS, i see the Proxmox bootscreen. But when entering Windows i see pixel blocks (both BIOS and UEFI). Any ideas?

I finally got it working with my Lenovo P14s. The Renoir_Generic_VBIOS_updGOP.bin is from https://forum.proxmox.com/threads/a...ss-thru-to-windows-10-guest.84849/post-418165 As I am new to Proxmox, there are probably many errors in my setting, but Windows 11 starts and I see it on the laptop screen.

You don't have pixelated screen? and no 43 error code in device manager?

No pixelated screen and no 43 error code.

I have Processor AMD Ryzen 7 PRO 4750U and Graphics adapter AMD Radeon RX Vega 7. Installed drivers on Win 11 via www.amd.com/en/support > Processors with graphics > AMD Ryxen PRO Processors > AMD Ryzen 7 PRO 4000 series Mobile Processors > AMD Ryzen 7 PRO 4750U

After reboot AMD Software says I have AMD Radeon PRO Graphics etc.

But I have problems getting Linux (tried MX Linux and Debian) to work with the graphics card, it only want to run with nomodeset with resolution 800x600
