Sleep mode is currently implemented only for a few CPUs. I should add
all the currently emulated cores. For this, I would have to emulate the
HID registers, in most case, which is still not done.

I could do this, as Qemu has definitions for most PowerPC cores (even if
most are still not available).
For now, you can take a look in target-ppc/translate_init.c. Most
PowerPC are referenced here:
- there's a big table with all the PVR I know (but there's still a lot
missing)
- the ppc_defs table contains most PowerPC definitions, with their
features defined.
I will think of doing a reference table on my web pages, to have a more
readable PowerPC reference document. Of course, any information about
missing PVRs or PowerPC implementation in welcome !
You can also take a look at the file target-ppc/STATUS file to figure
out all cores emulation working in Qemu.
And you can get the list of all CPUs emulated by Qemu with the '-cpu ?'
switch.
