[vfio-users] IGD Passthrough - does not work with intel kabylake

[nicolas prochazka]

For your information,
I just install native nuc kabylake with the same win10 ( without qemu .) ,
no problem, HD620 without error, native driver or intel support site.

So, it seems something annoying vfio or qemu , perhaps a new IGD
functionality ?

Regards
