AMD passthrough

[steff911]

Hi,

i want to passthrough my AMD GPU to an Windows 10 Machine.
When i insert the device with all function the vm doesn´t start with error message:

failed to setup container for group 35: Failed to set iommu for container: Operation not permitted

When i try the same with only the gpu functions the machine starts. So i think there will be something wrong with the audio functions.
In the modprobe blacklist are these entries:

blacklist radeon
blacklist nouveau
blacklist nvidia
blacklist snd_hda_intel

as this message says, it is a platform restriction (aka the mainboard), check with the mainboard vednor
