But what would I put there?... IOMMU ID is more than enough at the moment
and struct iommu_table does not have anything what would have made sense to
show in the sysfs...

I believe David mentioned that PEs had user visible names.  Perhaps they
match an enclosure location or something.  Group numbers are rather
arbitrary and really have no guarantee of persistence.  Thanks,

I agree. Make up something, for example domain[PE] or something like
that.

To be able to add a PE number, I need to call iommu_group_alloc() in the correct place where I know this number OR I have to carry it in iommu_table till the moment the iommu_group_alloc() is called (acceptable but not cool).

I will post a patch which would help as a response to this mail.
