5dd68db9cd docs: Bump sphinx to 6.2.1
sphinx 5.3.0 fails with Python 3.13.1:

../docs/meson.build:37: WARNING: /home/me/qemu/build/pyvenv/bin/sphinx-build:
Extension error:
Could not import extension sphinx.builders.epub3 (exception: No module named 'imghdr')

../docs/meson.build:39:6: ERROR: Problem encountered: Install a Python 3 version of python-sphinx and the readthedoc theme

Bump sphinx to 6.2.1 and also sphinx_rtd_theme as required for the new
sphinx version.

(jsnow note: this patch bumps the recommended version for Sphinx to
install when it is missing, but allows old versions to be used if they
are present and functional. The version used for building docs on
readthedocs is pinned to the recommended version, 6.2.1.)

c156395252 qemu-img: rebase: refresh options/--help (short option change)
Add missing long options and --help output,
reorder options for consistency.

Use -B for --backing-format, keep -F for
backwards compatibility.

Options added:
 --format, --cache - for the image in question
 --backing, --backing-format, --backing-cache, --backing-unsafe -
   for the new backing file
(was eg CACHE vs SRC_CACHE, which is unclear).

Probably should rename local variables.

When no -l/-a/-c/-d specified, assume -l (list).

Use the same values for SNAPSHOT_LIST/etc constants as the
option chars (lacd), this makes it possible to simplify
option handling a lot, combining cases for 4 options into
one.

Also remove bdrv_oflags handling (only list can use RO mode).

300dcf58b7 vfio/migration: Max in-flight VFIO device state buffers size limit
Allow capping the maximum total size of in-flight VFIO device state buffers
queued at the destination, otherwise a malicious QEMU source could
theoretically cause the target QEMU to allocate unlimited amounts of memory
for buffers-in-flight.

Since this is not expected to be a realistic threat in most of VFIO live
migration use cases and the right value depends on the particular setup
disable this limit by default by setting it to UINT64_MAX.

This property allows configuring whether to start the config load only
after all iterables were loaded, during non-iterables loading phase.
Such interlocking is required for ARM64 due to this platform VFIO
dependency on interrupt controller being loaded first.

The property defaults to AUTO, which means ON for ARM, OFF for other
platforms.

Besides the better visual formatting, it also helps with accessibility

636c96cd77 qapi: Fix undocumented return values by generating something
Generated command documentation lacks information on return value in
several cases, e.g. query-tpm.

The obvious fix would be to require a Returns: section when a command
returns something.

However, note that many existing Returns: sections are pretty useless:
the description is basically the return type, which then gets rendered
like "Return: <Type> – <basically the return type>".  This suggests
that a description is often not really necessary, and requiring one
isn't useful.

Instead, generate the obvious minimal thing when Returns: is absent:
"Return: <Type>".

This auto-generated Return documentation is placed is as follows:

1. If we have arguments, return goes right after them.
2. Else if we have errors, return goes right before them.
3. Else if we have features, return goes right before them.
4. Else return goes right after the intro

To facilitate this algorithm, a "TODO:" hack line is used to separate
the intro from the remainder of the documentation block in cases where
there are no other sections to separate the intro from e.g. examples and
additional detail meant to appear below the key sections of interest.

2e51072ae5 docs/qapi-domain: add return-nodesc
This form is used to annotate a return type without an accompanying
description, for when there is no "Returns:" information in the source
doc, but we have a return type we want to generate a cross-reference to.

The syntax is:

:return-nodesc: TypeName

It's primarily necessary because Sphinx always expects both a type and a
description for the prior form and will format it accordingly. To have a
reasonable rendering when the body is missing, we need to use a
different info field list entirely.

8d789c8cdb docs/sphinx: remove legacy QAPI manual generator
Thanks for your service!

Remove the old qapidoc and the option to enable the transmogrifier,
leaving the "transmogrifier" as the ONLY qapi doc generator. This in
effect also converts the QAPI test to use the new documentation
generator, too.

Update doc-good.txt output to match the new doc generator, which I
should've done exactly when we switched over to the transmogrifier, but,
uhh, oops!

Notes on the new format:
 1. per-member IFCOND documentation is missing. Known issue.
 2. Freeform documentation without a header is now copied through into
    the output. This is a bug fix.

da703b06a5 net/passt: Implement vhost-user backend support
This commit adds support for the vhost-user interface to the passt
network backend, enabling high-performance, accelerated networking for
guests using passt.

The passt backend can now operate in a vhost-user mode, where it
communicates with the guest's virtio-net device over a socket pair
using the vhost-user protocol. This offloads the datapath from the
main QEMU loop, significantly improving network performance.

When the vhost-user=on option is used with -netdev passt, the new
vhost initialization path is taken instead of the standard
stream-based connection.

854ee02b22 net: Add passt network backend
This commit introduces support for passt as a new network backend.
passt is an unprivileged, user-mode networking solution that provides
connectivity for virtual machines by launching an external helper process.

The implementation reuses the generic stream data handling logic. It
launches the passt binary using GSubprocess, passing it a file
descriptor from a socketpair() for communication. QEMU connects to
the other end of the socket pair to establish the network data stream.

The PID of the passt daemon is tracked via a temporary file to
ensure it is terminated when QEMU exits.

beeac2df5f migration: Rename save_live_complete_precopy_thread to save_complete_precopy_thread
Recent patch [1] renames the save_live_complete_precopy handler to
save_complete, as the machine is not live in most cases when this
handler is executed. The same is true also for
save_live_complete_precopy_thread, therefore this patch removes the
"live" keyword from the handler itself and related types to keep the
naming unified.

In contrast to save_complete, this handler is only executed at the end
of precopy, therefore the "precopy" keyword is retained.

57c43e52bd migration: Rename save_live_complete_precopy to save_complete
Now after merging the precopy and postcopy version of complete() hook,
rename the precopy version from save_live_complete_precopy() to
save_complete().

Dropping the "live" when at it, because it's in most cases not live when
happening (in precopy).

No functional change intended.

When at it, removing the NOTE because it's incorrect now after introduction

9d8ade51a2 hw/arm/virt: Basic CXL enablement on pci_expander_bridge instances pxb-cxl
Code based on i386/pc enablement.
The memory layout places space for 16 host bridge register regions after
the GIC_REDIST2 in the extended memmap. This is a hole in the current
map so adding them here has no impact on placement of other memory regions
(tested with enough CPUs for GIC_REDIST2 to be in use.)
The high memory map is GiB aligned so the hole is there whatever the
size of memory or device_memory below this point.

The CFMWs are placed above the extended memmap. Note the existing
variable highest_gpa is the highest GPA that has been allocated at
a particular point in setting up the memory map. Whilst this caused
some confusion in review there are existing comments explaining this
so nothing is added.

The cxl_devices_state.host_mr provides a small space in which to place
the individual host bridge register regions for whatever host bridges are
allocated via -device pxb-cxl on the command line. The existing dynamic
sysbus infrastructure is not reused because pxb-cxl is a PCI device not
a sysbus one but these registers are directly in the main memory map,
not the PCI address space.

Only create the CEDT table if cxl=on set for the machine. Default to off.

9526b9b620 hw/arm/highbank: Mark the "highbank" and the "midway" machine as deprecated
We don't have any automatic regression tests for these machines and
when asking the usual suspects on the mailing list we came to the
conclusion that nobody tests these machines manually, too, so it seems
like this is currently just completely unused code. Mark them as depre-
cated to see whether anybody still speaks up during the deprecation
period, otherwise we can likely remove these two machines in a couple
of releases.
