16b10fbf8b contrib/plugins/uftrace: add documentation
This documentation summarizes how to use the plugin, and present two
examples of the possibilities offered by it, in system and user mode.

As well, it explains how to rebuild and reproduce those examples.

cd64320e1e docs/code-provenance: AI exceptions are in addition to DCO
Using phrasing from https://openinfra.org/legal/ai-policy (with just
"commit" replaced by "submission", because we do not submit changes
as commits but rather emails), clarify that the contributor remains
responsible for its copyright or license status.

[This is not my preferred phrasing.  I would prefer something lighter
like "the "Signed-off-by" label in the contribution gives the author
responsibility".  But for the sake of not reinventing the wheel I am
keeping the exact words from the OpenInfra policy.]

9ceb9b42c8 docs/code-provenance: make the exception process more prominent
QEMU's AI generated content policy does not flesh out the exception
process yet.  Do it, while at the same time keeping things informal: ask
contributors to explain what they would like to use AI for, and let them
reach a consensus with the project on why it is credible to claim DCO
compliance in that specific scenario.

In other words, exceptions do not "solve the AI copyright problem".  They
take a position that a reasonable contributor could have, and assert that
we're comfortable with the argument.

1f64df2547 docs/code-provenance: clarify scope very early
The AI policy in QEMU is not about content generators, it is about generated
content.  Other uses are explicitly not covered.  Rename the policy and clarify
its scope in the TL;DR section, as a matter of convenience to the reader.

62e82053fc docs/devel: Do not unparent in instance_finalize()
Children are automatically unparented so manually unparenting is
unnecessary.

Worse, automatic unparenting happens before the instance_finalize()
callback of the parent gets called, so object_unparent() calls in
the callback will refer to objects that are already unparented, which
is semantically incorrect.

Remove the instruction to call object_unparent(), and the exception
of the "do not call object_unparent()" rule for instance_finalize().

fcbe1080a4 docs: use the pyvenv version of Meson
The version in the system might be too old for QEMU; this will be
especially true if Rust is going to be enabled by default.

Adjust the docs to suggest using pyvenv/bin/meson, which is in fact
what the "make" wrappers will be running internally.

dcdee1e718 rust: vmstate: use const_refs_to_static
The VMStateDescriptionBuilder already needs const_refs_static, so
use it to remove the need for vmstate_clock! and vmstate_struct!,
as well as to simplify the implementation for scalars.

If the consts in the VMState trait can reference to static
VMStateDescription, scalars do not need the info_enum_to_ref!
indirection and structs can implement the VMState trait themselves.

7da9ee9207 rust: vmstate: convert to use builder pattern
Similar to MemoryRegionOps, the builder pattern has two advantages:
1) it makes it possible to build a VMStateDescription that knows which
types it will be invoked on; 2) it provides a way to wrap the callbacks
and let devices avoid "unsafe".

Unfortunately, building a static VMStateDescription requires the
builder methods to be "const", and because the VMStateFields are
*also* static, this requires const_refs_static.  So this requires
Rust 1.83.0.

9cf342b491 accel/tcg: create a thread-kick function for TCG
Round-robin TCG is calling into cpu_exit() directly.  In preparation
for making cpu_exit() usable from all accelerators, define a generic
thread-kick function for TCG which is used directly in the multi-threaded
case, and through CPU_FOREACH in the round-robin case.

Use it also for user-mode emulation, and take the occasion to move
the implementation to accel/tcg/user-exec.c.

4b1e715912 qapi: switch to use QEMU_TEST_REGENERATE env var
The QAPI_TEST_UPDATE env var can be set when running the QAPI
schema tests to regenerate the reference output. For consistent
naming with the tracetool test, change the env var name to
QEMU_TEST_REGENERATE.

The test is modified to provide a hint about use of the new
env var and it is also added to the developer documentation.document its usage.

da949d495d tracetool: add test suite for tracetool with reference output
When reviewing tracetool patches it is often very unclear what the
expected output will be for the generated backends. Compounding
this is that a default build will only enable the 'log' trace
backend, so developers won't see generated code for other backends
without making a special effort. Some backends are also platform
specific, so can't be enabled in QEMU builds, even though tracetool
could generate the code.

To address this, introduce a test suite for tracetool which is
conceptually similar to the qapi-schema test. It is a simple
python program that runs tracetool and compares the actual output
to historical reference output kept in git. The test directly
emits TAP format logs for ease of integration with meson.

This can be run with

  make check-tracetool

to make it easier for developers changing generated output, the
sample expected content can be auto-recreated

  QEMU_TEST_REGENERATE=1 make check-tracetool

and the changes reviewed and added to the commit. This will also
assist reviewers interpreting the change.

Developers are reminded of this in the test output on failure:

  $ make check-tracetool
  1/6 qemu:tracetool / dtrace        OK              0.14s
  2/6 qemu:tracetool / ftrace        FAIL            0.06s   exit status 1

116c2c21d5 system: drop the -old-param option
We deprecated the command line option -old-param for the 10.0
release, which allows us to drop it in 10.2.  This option was used to
boot Arm targets with a very old boot protocol using the
'param_struct' ABI.  We only ever needed this on a handful of board
types which have all now been removed from QEMU.

5b3764d9e3 target/arm: Remove deprecated pxa CPU family
In 10.0 we deprecated the pxa CPU family (pxa250, pxa255, pxa260
pxa261, pxa262, pxa270-a0, pxa270-a1, pxa270, pxa270-b0, pxa270-b1,
pxa270-c0, pxa270-c5).  Now we have released 10.1 we can remove them.

This commit removes only the top level CPU definitions and updates
the documentation. Removing the CPUs means that there is now a lot
of dead iwMMXt code, which we will delete in subsequent commits.

ac7a892fd3 memory: Fix leaks due to owner-shared MRs circular references
Currently, QEMU refcounts the MR by always taking it from the owner.

It's common that one object will have multiple MR objects embeded in the
object itself.  All the MRs in this case share the same lifespan of the
owner object.

It's also common that in the instance_init() of an object, MR A can be a
container of MR B, C, D, by using memory_region_add_subregion*() set of
memory region APIs.

Now we have a circular reference issue, as when adding subregions for MR A,
we essentially incremented the owner's refcount within the instance_init(),
meaning the object will be self-boosted and its refcount can never go down
to zero if the MRs won't get detached properly before object's finalize().

Delete subregions within object's finalize() won't work either, because
finalize() will be invoked only if the refcount goes to zero first.  What
is worse, object_finalize() will do object_property_del_all() first before
object_deinit().  Since embeded MRs will be properties of the owner object,
it means they'll be freed _before_ the owner's finalize().

To fix that, teach memory API to stop refcount on MRs that share the same
owner.  Because if they share the lifecycle of the owner, then they share
the same lifecycle between themselves, hence the refcount doesn't help but
only introduce troubles.

Meanwhile, allow auto-detachments of MRs during finalize() of MRs even
against its container, as long as they belong to the same owner.

The latter is needed because now it's possible to have MRs' finalize()
happen in any order when they share the same lifespan with a same owner.
In this case, we should allow finalize() to happen in any order of either
the parent or child MR.  Loose the mr->container check in MR's finalize()
to allow auto-detach.  Double check it shares the same owner.

Proper document this behavior in code.

This patch is heavily based on the work done by Akihiko Odaki:

33be8171e2 scripts/kerneldoc: Switch to the Python kernel-doc script
Change the Sphinx config to run the new Python kernel-doc script
instead of the Perl one.  The only difference between the two is that
the new script does not handle the -sphinx-version option, instead
assuming that Sphinx is always at least version 3: so we must
delete the code that passes that option to avoid the Python
script complaining about an unknown option.

QEMU's minimum Sphinx version is already 3.4.3, so this doesn't
change the set of versions we can handle.

3f34478007 docs/sphinx/kerneldoc.py: Handle new LINENO syntax
The new upstream kernel-doc that we plan to update to uses a different
syntax for the LINENO directives that the Sphinx extension parses:
instead of
  #define LINENO 86
it has
  .. LINENO 86

Update the kerneldoc.py extension to handle both syntaxes, so
that it will work with both the old and the new kernel-doc.

e0b33efe2a vfio/igd: Require host VGA decode for legacy mode
Commit a59d06305f ("vfio/pci: Introduce x-pci-class-code option")
allows user to expose non-VGA IGD device as VGA controller to the
guest. However, legacy mode requires host VGA range access. Check
that GGC.IVD == 0 before enabling legacy mode to ensure IGD is a real
VGA device claiming host VGA ranges.
