The new powernv machine ships with a firmware that outputs
some text to the serial console, so we can automatically
test this machine type in the boot-serial tester, too.
And to get some (very limited) test coverage for the new
POWER9 CPU emulation, too, this test is also started with
"-cpu POWER9".

and we see the minimum :
[8450016,6] CPU: P9 generation processor(max 4 threads/core)
Reviewed-by: Cédric Le Goater <clg@kaod.org>
With very minimal changes (definition of some SPRs and the use
of the SHV mode), the guest would load the kernel.
Thanks,

Applied to ppc-for-2.8. Good to have this basic smoke test for
powernv.

yes. qom-test is also starting a powernv guest.
skiboot has a cool little program called hello_kernel that can be
run in place of the real kernel, but that's beyond the qemu layer
I guess
For qemu, maybe we could do xscom accesses to test some devices.

That would be good - the qtest framework is basically made for this
sort of thing.
