[vfio-users] intel skylake passthrough

[nicolas prochazka]

Hello,
I just need a confimation,
with my nuc broadwell I can do passthrough of my sound card without
problem,
because of a good iommu group, but it seems impossible with my new skylake
nuc
group 7 is not viable ......

please, tell me that a solution is possible .
Regards,
Nicolas

Broadwell
