AMD Radeon Reset Bug almost beaten - I Think


Oct 14, 2019
High, I've been going at the machine for almost a week now because i have certain requirments. I need hyperv nested VMS and a graphics card passthrough, I spent more than i should on different gpus trying to make it work. In order to get hyperv working i need the 440fx chipset and that doesn't allow me to get around nvidia code 43. I rushed out and brought an amd rx580 only to run into the reset bug. But in all my playing i might have come up with a solution. If i remove the device from the removable devices section, before shutting down. i can reboot the machine and use the rx580. I can script the removal on of the gpu on shutdown using deveject.exe and group policy. [c:\scripts\deveject.exe -EjectId:'PCI\VEN_1002&DEV_67DF&SUBSYS_C5801682&REV_E7\3&13C0B0C5&0&80' -v] has to run in powershell, not sure why.
This works ALWAYS when shutting down but not for reboot because the card isn't re-plugged. Then I got an idea, what if when windows was starting, I had a script that checked for the GPU, If not. hot plugged it.
Could someone help me learn qemu monitor please so I can complete this. I could ssh into pve from windows and run the qemu monitor commands to hot plug the gpu. That would be a complete work around for the reset bug. Please help.
The Proxmox VE 6.1 has a "reboot" feature, that triggers a shutdown and start. IIUC, this would make the qemu monitor commands unnecessary.
You are absolutely correct, while I initially couldn't get it to work without rebooting the machine. I changed the pci slot and it's worked ever since without making any mods. Thanks for clearing that up.
