[vfio-users] Unable to isolate HDMI device

[Karsten Elfenbein]

Hi Maxime,

the modules need to load in the correct order. In this case the
vfio-pci needs to load before the snd-hda-intel and nvidia.

I have the following lines on my Gentoo machine to achieve that:

cat /etc/modprobe.d/vfio.conf
softdep nvidia pre: vfio-pci
softdep snd-hda-intel pre: vfio-pci
...

Best regards
Karsten
