That's expected for lack of argument.

$ ./QMP/qom-list -s ./qmp-sock /machine
unattached/
peripheral/
peripheral-anon/
type

This confirms "path ... not fixed in code yet" (otherwise there would've
been an "spapr/" entry or anything else telling.

So you need to look through /machine/unassigned for the device[n] with
qom-get /machine/unassigned/device[n].type matching your type, possibly
device[0] as in my case. From there on you see your icp[0]/ and ics/
children without searching the unassigned list again.

Or simply use my qom-tree script:
http://lists.nongnu.org/archive/html/qemu-devel/2013-07/txte1WIbWzu5Z.txt

Setting a canonical path is done via object_property_add_child() after
instantiating and before realizing a device.
For x86 the northbridge is used as name, i.e. "i440fx" for pc and "q35"
for q35. Suggest to discuss with Anthony how to structure the
composition tree for sPAPR.
