Ryzen/NV GPU Passthrough works only on 6.5.3

[Jimmy235]

With only 1 core pegged the windows circle don‘t show up even anymore XD

Is this a fresh windows install or an old one?

[Jimmy235]

Tried it with a fresh one too. Exactly the same.

Can you please setup a VM without any devices like GPU or sound/mouse/keyboard, only VNC? Basic install, nothing else. Enable RDP or install Teamviewer or Nomaschine and make sure you can connect to the VM. After that shut down the VM, add your GPU + GPU audio and start it up.

So, set up a VM, installed fresh Win10 over VNC. No problem, worked fine.

After shutting down and adding GPU+dumped.rom —> again nothing, black screen

Please add the the pci ids of your card to your syslinux config so unraid won't pickup the card and restart the server. Go to main tab and click "Flash". There you find the config. 

 

Example of my entry for the default boot option without pci ids:

append isolcpus=8-15,24-31 pcie_aspm=off initrd=/bzroot

and with ids added:

append vfio-pci.ids=10de:1b06,10de:10ef isolcpus=8-15,24-31 pcie_aspm=off initrd=/bzroot

 

If you are on 6.7 you can also try the new method with BIND instead.
