Hi guys, I had a working proxmox 8.1 system based on Asrock Z690 m/b with AMD RX6600XT gpu. This gpu passtrough worked perfectly in linux, windows and macos. In guests it was located at PciRoot(0x1)/Pci(0x1C,0x0)/Pci(0x0,0x0) Recently I've changed m/b to Asus Z790-P CSM and in guests my gpu now is located at PciRoot(0x0)/Pci(0x1C,0x0)/Pci(0x0,0x0) Linux and windows guests work fine with gpu in new location, however macos guest doesn't want to recognize gpu. Is there any way to tell qemu to passthrough gpu to an old location in guest: PciRoot(0x1)/Pci(0x1C,0x0)/Pci(0x0,0x0)?
