We use a S390PCIGroup structure to hold the information related to a
zPCI Function group.

This allows us to be ready to support multiple groups and to retrieve
the group information from the host.

I think you made the identifiers a bit too compact :)
s390_group_create() is not that long, and I have no idea what the 'ug'
(ugh :) parameter is supposed to mean.


Ha :) Message received, something like s390_group_create(int id) is probably more appropriate.

group?

+    S390pciState *s = s390_get_phb();

+    grp = g_new0(S390PCIGroup, 1);

zpci_groups? I think you get the idea :)


Yep, thanks!

+    return grp;

No objection to the patch in general.
