[vfio-users] Z170X IOMMU Groups

[Nick Sarnie]

Hi Alex,

The output is here: http://pastebin.com/raw/qjnpuaVr
Also, is there any way we could move the USB controller into its own group,
or remove the Ethernet and SATA controller into a seperate group? Ideally,
I could pass the USB Controller in group 7 without the ACS patch.

Thanks,
sarnex
