vendor-reset VS amdvbflash

I have the vendor-reset fix. I have disabled resizable bar, and I have added the fix for the AMD driver detecting the VM in the XML file.

I’m not sure what you mean by forwarding, but if you mean regular gpu passthrough and the reset bugs with amd gpus, then for the rx580 vendor-reset should typically work: https://github.com/gnif/vendor-reset

Does not work with the lower 6000 (below 6800) and 7000 series that can also have reset issues.

Just an update installing vendor-reset to counteract the amd gpu reset bug fixed my issues completely. Are you running an amd gpu by chance, it may be worth a shot to try it. https://github.com/gnif/vendor-reset

I'd try just reinstalling drivers on windows, and if that doesn't work I'd check the bios on the card with amdVBflash and if the bios is different than the version here for whatever card you have, I'd flash the bios then use DDU on windows and try reinstalling the drivers again.

I used to have an RX580-based single GPU passthrough setup. You likely need the vendor reset module, since hot-plugging Polaris 10 GPUs is a bit buggy and can cause GPU lockups. It might also be worth dumping your GPU bios and configuring libvirt to use it so you get a visible boot screen (tool). I think I mostly followed this guide, however it hasn't been updated in quite a while it seems.

quadruple checked How to Flash AMD GPU VBIOS on Linux and the README.md

Well, turns out PolarisBiosEditor 1.6.5 runs just fine with the latest stable version of WINE and amdvbflash is also easy to come across (https://github.com/stylesuxx/amdvbflash)
