ppc patch queue 2019-02-26

Next set of patches for ppc and spapr. There's a lot in this one:
* Support "STOP light" states on POWER9
* Add support for HVI interrupts on POWER9 (powernv machine)
* CVE-2019-8934: Don't leak host model and serial information to the guest
* Tests and cleanups for various hot unplug options
* Hash and radix MMU implementation on POWER9 for powernv machine
* PCI Host Bridge hotplug support for pseries machine
* Allow larger kernels and initrds for powernv machine

Plus a handful of miscellaneous fixes and cleanups.

The cpu hotplug tests and cleanups from David Hildenbrand aren't
solely power related. However the consensus amongst Michael Tsirkin,
David Hildenbrand, Cornelia Huck and myself was that it made most
sense to come in via my tree.

hw/ppc: Use object_initialize_child for correct reference counting

Both functions, object_initialize() and object_property_add_child() increase
the reference counter of the new object, so one of the references has to be
dropped afterwards to get the reference counting right. Otherwise the child
object will not be properly cleaned up when the parent gets destroyed.
Thus let's use now object_initialize_child() instead to get the reference
counting here right.

Hotplugging PHBs is a machine-level operation, but PHBs reside on the

Provide the usual pre-plug, plug and unplug-request handlers.

Move the checking of the PHB index to the pre-plug handler. It is okay
to do that and assert in the realize function because the pre-plug
handler is always called, even for the oldest machine types we support.

With mttcg, we can have MMU lookups happening at the same time

Since the HPTEs of the hash table MMU contains two words (or
double worlds on 64-bit), we need to make sure we read them
in the right order, with the correct memory barrier.

Additionally, when using emulated SPAPR mode, the hypercalls
writing to the hash table must also perform the udpates in
the right order.

target/ppc/spapr: Set LPCR:HR when using Radix mode

The HW relies on LPCR:HR along with the PATE to determine whether
to use Radix or Hash mode. In fact it uses LPCR:HR more commonly
than the PATE.

For us, it's also more efficient to do so, especially since unlike
the HW we do not maintain a cache of the current PATE and HV PATE
in a generic place.

Prepare the grounds for that by ensuring that LPCR:HR is set
properly on SPAPR machines.

Another option would have been to use a callback to get the PATE
but this gets messy when implementing bare metal support, it's
much simpler (and faster) to use LPCR.

Since existing migration streams may not have it, fix it up in
spapr_post_load() as well based on the pseudo-PATE entry that
we keep.

elf: Add optional function ptr to load_elf() to parse ELF notes

This patch adds an optional function pointer, 'elf_note_fn', to
load_elf() which causes load_elf() to additionally parse any
ELF program headers of type PT_NOTE and check to see if the ELF
Note is of the type specified by the 'translate_opaque' arg.
If a matching ELF Note is found then the specfied function pointer
is called to process the ELF note.

Passing a NULL function pointer results in ELF Notes being skipped.

The first consumer of this functionality is the PVHboot support
which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while
loading the uncompressed kernel binary in order to discover the
boot entry address for the x86/HVM direct boot ABI.

hw/ppc/spapr: Add support for "-vga cirrus"

The cirrus VGA card has been enabled in the PPC builds with
commit 29f9cef39eb1ae55e82c ("ppc: Include vga cirrus card into

also support this for the "-vga" parameter here.
