To clarify for everyone what we're talking about here, I'm attaching
/machine composition tree dumps for pc,accel=kvm and q35,accel=kvm plus
the rudimentary script I used to generate it.
It shows for instance the mentioned /machine/i440fx and lack of
/machine/q35. It also shows that there would be a /machine/fw_cfg.
Paths starting with /machine/unassigned shouldn't be hardcoded anywhere
(that's the nobody-added-it-as-a-child<> bucket), except maybe for
/machine/unassigned/sysbus. But whenever there's a link from a named
device to a /machine/unassigned/device[n] that may of course be used
dynamically, e.g. /machine/icc-bridge/icc to discover CPUs and APICs.
HTH,
Andreas
