Hmm... -h is common to all targets, ie, you should only find properties
that can be passed to -machine for all qemu-system-* binaries (I don't
know how s390-squash-mcss landed there but it looks wrong).
The right way to query properties supported by a pseries machine type
is:
$ ./ppc64-softmmu/qemu-system-ppc64 -machine pseries,help
pseries-2.11.kvm-type=string (Specifies the KVM virtualization mode (HV, PR))
pseries-2.11.vsmt=uint32 (Virtual SMT: KVM behaves as if this were the host's SMT mode)
pseries-2.11.modern-hotplug-events=bool (Use dedicated hotplug event mechanism in place of standard EPOW events when possible (required for memory hot-unplug support))
pseries-2.11.max-cpu-compat=string (Maximum permitted CPU compatibility mode. Valid values are power6, power7, power7+, power8, power9.)
pseries-2.11.resize-hpt=string (Resizing of the Hash Page Table (enabled, disabled, required))
pseries-2.11.kvm-shadow-mem=int (KVM shadow MMU size)
pseries-2.11.enforce-config-section=bool (Set on to enforce configuration section migration)
pseries-2.11.initrd=string (Linux initial ramdisk file)
pseries-2.11.mem-merge=bool (Enable/disable memory merge support)
pseries-2.11.firmware=string (Firmware image)
pseries-2.11.dtb=string (Linux kernel device tree file)
pseries-2.11.suppress-vmdesc=bool (Set on to disable self-describing migration)
pseries-2.11.usb=bool (Set on/off to enable/disable usb)
pseries-2.11.kernel=string (Linux kernel image file)
pseries-2.11.dt-compatible=string (Overrides the "compatible" property of the dt root node)
pseries-2.11.igd-passthru=bool (Set on/off to enable/disable igd passthrou)
pseries-2.11.dumpdtb=string (Dump current dtb to a file and quit)
pseries-2.11.append=string (Linux kernel command line)
pseries-2.11.accel=string (Accelerator list)
pseries-2.11.kernel-irqchip=OnOffSplit (Configure KVM in-kernel irqchip)
pseries-2.11.dump-guest-core=bool (Include guest memory in a core dump)
pseries-2.11.phandle-start=int (The first phandle ID we may generate dynamically)
pseries-2.11.graphics=bool (Set on/off to enable/disable graphics emulation)

That output comes from qemu-options.hx, which contains information
added by hand. That means that some machine options end up there, some
don't. If this is only supposed to contain common options, we should
remove s390-squash-mcss (and the -key-wrap ones are s390-specific as
well).

Indeed. This contains the real set of properties and does not depend on
whether a developer added some extra help text.
