Anthony Liguori - Dec. 16, 2011, 6:08 p.m.
First, please notice the 'RFC' tag and the lack of a Signed-off-by.  I'm just
making a proposal here so please don't bite my head off if this isn't a good
idea.

I notice that these two machines have seem to have never really been touched
other than tree-wide refactoring since their introduction.  Googling for the
machine types doesn't hit any user questions or comments about the machine
types.

For the most part, the devices haven't been converted to qdev and are actually
the only remaining PCI devices that haven't been.

To me this indicates that the code currently isn't being used by anyone.  I
can do the qdev conversions if it is, but as far as I can tell, it's just bit
rotting right now.

Is this accurate?  Can we remove this code?  If there is future interest here,
it's easy enough to revert this, fix up the code, and resubmit.

No. There's an easy explanation why you might not find much mentions of
the machine names: g3beige (ppc_oldworld.c) is the default for
qemu-system-ppc, and mac99 (ppc_newworld.c) is the default for
qemu-system-ppc64.

If there's something ppc you'd like to remove then I would be open about
discussing the current ppc_prep.c machine but not its infrastructure
(prep_pci etc. - there we started a qdev'ification) as that's needed for
40p and bebox machines. I was holding back any refactorings while
MemoryRegion API was a moving target and now QOM didn't seem inviting
either. ;)

True point. I just find it frustrating to work on something so it works the same way as before again. Maybe someone a bit less spoiled could convert them over?

It's the default machine. Admittedly it's not the greatest and best maintained code in the world, but I guess that applies for multiple corners of QEMU.

Yeah. We talked about moving the default for ppc64 to pseries. At that point we could start to talk about dropping -M mac99 (which is in horrible shape). For -M g3beige, I don't see an alternative popping up atm. It's the only sane target we have for book3s_32 guests.
