Sounnds reasonable to me:
1. Drop --log and --phys; only have --verb
2. Print phys as an attribute; print lots more phys's with --verb
3. I don't have much of an opinion wrt gui output, but it should be consistent with all the other flavors of output

I am asking people here, some are confused by all these
--logical/--physical outputs. One idea that came is to always keep the
logical index and print the physical index as an attribute. Something like:
$ lstopo -
Machine(1508MB) + Socket#0 (phys=0) + L2(phys=0,2048KB)
L1(phys=0,32KB) + Core#0(phys=0) + P#0(phys=0)
L1(phys=1,32KB) + Core#1(phys=1) + P#1(phys=1)
I am interested by this idea. The physical index could actually be
displayed as an attribute for Proc all the time since it's often
interesting. The physical index of other objects is often useless and
So what about we:
1) keep --logical by default, add physical index in Proc attributes by
2) if --verbose, we add the physical index in every object attribute
3) if --physical, we replace #0 with physical indexes as #0p (and don't
print logical indexes anywhere)
I would actually just drop (3). If we really need --physical to match
other tools command-line options, we could just make --physical
equivalent to --verbose.
