Get the Ryzen 7000 series processors with AMD Radeon 680M/780M integrated graphics or RDNA2/RDNA3 GPUs running with Proxmox, GPU passthrough and UEFI included.
After two days of mind-numbing troubleshooting I finally figured it out!
I had to switch from SeaBIOS to UEFI bios and now the passthrough works with the bios extracted from the iGPU :)
The passthrough (output to a monitor) did not work at all for me with SeaBIOS and with UEFI one it worked even before I attached the vbios, although with error 43. After I attached the vbios and AMDGopDriver.rom the passthrough now works 100% <3 Thanks for a great guide!
