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.
