Here's a (probably) final pull request before the qemu-6.1 soft
freeze. Includes:
* Implementation of the new H_RPT_INVALIDATE hypercall
* Virtual Open Firmware for pSeries and pegasos2 machine types.
This is an experimental minimal Open Firmware implementation which
works by delegating nearly everything to qemu itself via a special
hypercall.
* A number of cleanups to the ppc soft MMU code
* Fix to handling of two-level radix mode translations for the
powernv machine type
* Update the H_GET_CPU_CHARACTERISTICS call with newly defined bits.
This will allow more flexible handling of possible future CPU
Spectre-like flaws
* Correctly treat mtmsrd as an illegal instruction on BookE cpus
* Firmware update for the ppce500 machine type

spapr: Implement Open Firmware client interface
The PAPR platform describes an OS environment that's presented by
a combination of a hypervisor and firmware. The features it specifies
require collaboration between the firmware and the hypervisor.
Since the beginning, the runtime component of the firmware (RTAS) has
been implemented as a 20 byte shim which simply forwards it to
a hypercall implemented in qemu. The boot time firmware component is
SLOF - but a build that's specific to qemu, and has always needed to be
updated in sync with it. Even though we've managed to limit the amount
of runtime communication we need between qemu and SLOF, there's some,
and it has become increasingly awkward to handle as we've implemented
new features.
This implements a boot time OF client interface (CI) which is
enabled by a new "x-vof" pseries machine option (stands for "Virtual Open
Firmware). When enabled, QEMU implements the custom H_OF_CLIENT hcall
which implements Open Firmware Client Interface (OF CI). This allows
using a smaller stateless firmware which does not have to manage
the device tree.
The new "vof.bin" firmware image is included with source code under
pc-bios/. It also includes RTAS blob.
This implements a handful of CI methods just to get -kernel/-initrd
working. In particular, this implements the device tree fetching and
simple memory allocator - "claim" (an OF CI memory allocator) and updates
"/memory@0/available" to report the client about available memory.
This implements changing some device tree properties which we know how
to deal with, the rest is ignored. To allow changes, this skips
fdt_pack() when x-vof=on as not packing the blob leaves some room for
appending.
In absence of SLOF, this assigns phandles to device tree nodes to make
device tree traversing work.
When x-vof=on, this adds "/chosen" every time QEMU (re)builds a tree.
This adds basic instances support which are managed by a hash map
ihandle -> [phandle].
Before the guest started, the used memory is:
0..e60 - the initial firmware
8000..10000 - stack
400000.. - kernel
3ea0000.. - initramdisk
This OF CI does not implement "interpret".
Unlike SLOF, this does not format uninitialized nvram. Instead, this
includes a disk image with pre-formatted nvram.
With this basic support, this can only boot into kernel directly.
However this is just enough for the petitboot kernel and initradmdisk to
boot from any possible source. Note this requires reasonably recent guest
kernel with:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=
df5be5be8735
The immediate benefit is much faster booting time which especially
crucial with fully emulated early CPU bring up environments. Also this
may come handy when/if GRUB-in-the-userspace sees light of the day.
This separates VOF and sPAPR in a hope that VOF bits may be reused by
other POWERPC boards which do not support pSeries.
This assumes potential support for booting from QEMU backends
such as blockdev or netdev without devices/drivers used.

target/ppc: fix address translation bug for radix mmus
This commit attempts to fix a technical hiccup first mentioned by Richard
Henderson in
https://lists.nongnu.org/archive/html/qemu-devel/2021-05/msg06247.html
To sumarize the hiccup here, when radix-style mmus are translating an
address, they might need to call a second level of translation, with
hypervisor privileges. However, the way it was being done up until
this point meant that the second level translation had the same
privileges as the first level. It could lead to a bug in address
translation when running KVM inside a TCG guest, but this bug was never
experienced by users, so this isn't as much a bug fix as it is a
correctness cleanup.
This patch attempts that cleanup by making radix64_*_xlate functions
receive the mmu_idx, and passing one with the correct permission for the
second level translation.
The mmuidx macros added by this patch are only correct for non-bookE
mmus, because BookE style set the IS and DS bits inverted and there
might be other subtle differences. However, there doesn't seem to be
BookE cpus that have radix-style mmus, so we left a comment there to
document the issue, in case a machine does have that and was missed.
As part of this cleanup, we now need to send the correct mmmu_idx
when calling get_phys_page_debug, otherwise we might not be able to see the
memory that the CPU could

how much space the RTAS requires to work which includes the RTAS binary

target/ppc: Introduce ppc_interrupts_little_endian()
PowerPC CPUs use big endian by default but starting with POWER7,
server grade CPUs use the ILE bit of the LPCR special purpose
register to decide on the endianness to use when handling
interrupts. This gives a clue to QEMU on the endianness the
guest kernel is running, which is needed when generating an
ELF dump of the guest or when delivering an FWNMI machine
check interrupt.
Commit
382d2db62bcb ("target-ppc: Introduce callback for interrupt
endianness") added a class method to PowerPCCPUClass to modelize
this : default implementation returns a fixed "big endian" value,
while POWER7 and newer do the LPCR_ILE check. This is suboptimal
as it forces to implement the method for every new CPU family, and
it is very unlikely that this will ever be different than what we
have today.
We basically only have three cases to consider:
a) CPU doesn't have an LPCR => big endian
b) CPU has an LPCR but doesn't support the ILE bit => big endian
c) CPU has an LPCR and supports the ILE bit => little or big endian
Instead of class methods, introduce an inline helper that checks the
ILE bit in the LPCR_MASK to decide on the outcome. The new helper
words little endian instead of big endian. This allows to drop a !
operator in ppc_cpu_do_fwnmi_machine_check().

vfio: Disable only uncoordinated discards for VFIO_TYPE1 iommus
We support coordinated discarding of RAM using the RamDiscardManager for
the VFIO_TYPE1 iommus. Let's unlock support for coordinated discards,
keeping uncoordinated discards (e.g., via virtio-balloon) disabled if
possible.
This unlocks virtio-mem + vfio on x86-64. Note that vfio used via "nvme://"
by the block layer has to be implemented/unlocked separately. For now,
virtio-mem only supports x86-64; we don't restrict RamDiscardManager to
x86-64, though: arm64 and s390x are supposed to work as well, and we'll
test once unlocking virtio-mem support. The spapr IOMMUs will need special
care, to be tackled later, e.g.., once supporting virtio-mem.
Note: The block size of a virtio-mem device has to be set to sane sizes,
depending on the maximum hotplug size - to not run out of vfio mappings.
The default virtio-mem block size is usually in the range of a couple of
MBs. The maximum number of mapping is 64k, shared with other users.
Assume you want to hotplug 256GB using virtio-mem - the block size would
have to be set to at least 8 MiB (resulting in 32768 separate mappings).

vfio: Support for RamDiscardManager in the vIOMMU case
vIOMMU support works already with RamDiscardManager as long as guests only
map populated memory. Both, populated and discarded memory is mapped
into &address_space_memory, where vfio_get_xlat_addr() will find that
memory, to create the vfio mapping.
Sane guests will never map discarded memory (e.g., unplugged memory
blocks in virtio-mem) into an IOMMU - or keep it mapped into an IOMMU while
memory is getting discarded. However, there are two cases where a malicious
guests could trigger pinning of more memory than intended.
One case is easy to handle: the guest trying to map discarded memory
into an IOMMU.
The other case is harder to handle: the guest keeping memory mapped in
the IOMMU while it is getting discarded. We would have to walk over all
mappings when discarding memory and identify if any mapping would be a
violation. Let's keep it simple for now and print a warning, indicating
that setting RLIMIT_MEMLOCK can mitigate such attacks.
We have to take care of incoming migration: at the point the
IOMMUs get restored and start creating mappings in vfio, RamDiscardManager
implementations might not be back up and running yet: let's add runstate
priorities to enforce the order when restoring.

virtio-mem: Implement RamDiscardManager interface
Let's properly notify when (un)plugging blocks, after discarding memory
and before allowing the guest to consume memory. Handle errors from
notifiers gracefully (e.g., no remaining VFIO mappings) when plugging,
rolling back the change and telling the guest that the VM is busy.
One special case to take care of is replaying all notifications after
restoring the vmstate. The device starts out with all memory discarded,
so after loading the vmstate, we have to notify about all plugged
blocks.

memory: Introduce RamDiscardManager for RAM memory regions
We have some special RAM memory regions (managed by virtio-mem), whereby
the guest agreed to only use selected memory ranges. "unused" parts are
discarded so they won't consume memory - to logically unplug these memory
ranges. Before the VM is allowed to use such logically unplugged memory
again, coordination with the hypervisor is required.
This results in "sparse" mmaps/RAMBlocks/memory regions, whereby only
coordinated parts are valid to be used/accessed by the VM.
In most cases, we don't care about that - e.g., in KVM, we simply have a
single KVM memory slot. However, in case of vfio, registering the
whole region with the kernel results in all pages getting pinned, and
therefore an unexpected high memory consumption - discarding of RAM in
that context is broken.
Let's introduce a way to coordinate discarding/populating memory within a
RAM memory region with such special consumers of RAM memory regions: they
can register as listeners and get updates on memory getting discarded and
populated. Using this machinery, vfio will be able to map only the
currently populated parts, resulting in discarded parts not getting pinned
and not consuming memory.
A RamDiscardManager has to be set for a memory region before it is getting
mapped, and cannot change while the memory region is mapped.
Note: At some point, we might want to let RAMBlock users (esp. vfio used
for nvme://) consume this interface as well. We'll need RAMBlock notifier
calls when a RAMBlock is getting mapped/unmapped (via the corresponding
memory region), so we can properly register a listener there as well.

vl: switch -M parsing to keyval
Switch from QemuOpts to keyval. This enables the introduction
of non-scalar machine properties, and JSON syntax in the future.
For JSON syntax to be supported right now, we would have to
consider what would happen if string-based dictionaries (produced by
-M key=val) were to be merged with strongly-typed dictionaries
(produced by -M {'key': 123}).
The simplest way out is to never enter the situation, and only allow one
-M option when JSON syntax is in use. However, we want options such as
-smp to become syntactic sugar for -M, and this is a problem; as soon
as -smp becomes a shortcut for -M, QEMU would forbid using -M '{....}'
together with -smp. Therefore, allowing JSON syntax right now for -M
would be a forward-compatibility nightmare and it would be impossible
anyway to introduce -M incrementally in tools.
Instead, support for JSON syntax is delayed until after the main
options are converted to QOM compound properties. These include -boot,
-acpitable, -smbios, -m, -semihosting-config, -rtc and -fw_cfg. Once JSON
syntax is introduced, these options will _also_ be forbidden together
with -M '{...}'.

meson: sort existing compiler tests
The next patches will add more compiler tests. Sort and group the
existing tests, keeping similar cc.has_* tests together and sorting them
alphabetically by macro name. This should make it easier to look for
examples when adding new tests to meson.build.

configure: drop vte-2.90 check
All currently supported distros have vte 0.37 or newer, which is where the
ABI changed from 2.90 to 2.91. So drop support for the older ABI.

Rather than relying on the X86XSaveArea structure definition directly,

Currently the offsets declared in the array are derived from the
