12b4267d60 python/qapi: delint import statements
Missed a spot with isort, which now causes the python-minreqs test on
GitLab to fail. Fix it.

(Hint: the commands in python/tests/qapi-isort.sh can be run without the
"-c" parameter to automatically adjust import statements according to
our style rules. Maybe I should make a pre-submit hook that makes this
adjustment automatically. What do you think?)

b1085f87ef mtest2make: add dependencies to the "speed-qualified" suite
Thorough tests may have more dependencies than faster ones.
Dependencies are now looked up based on the suites being
executed, not on the suites passed as goals to the makefile.
Therefore, it is possible to limit dependencies to the
speeds that need them.

add it only when actually computing the arguments to "meson test".
This makes it possible to set ninja-cmd-goals from the set of suites,

8107ba47fd qapi: Add documentation format validation
Add explicit validation for QAPI documentation formatting rules:

1. Lines must not exceed 70 columns in width (including '# ' prefix)
2. Sentences must be separated by two spaces

Example sections and literal :: blocks (seldom case) are excluded, we
don't require them to be <= 70, that would be too restrictive. Anyway,
they share common 80-columns recommendations (not requirements).

Add two simple tests, illustrating the change.

5bd89761a4 qapi/command: Avoid generating unused qmp_marshal_output_T()
qmp_marshal_output_T() is only ever called by qmp_marshal_C() for a
command C that returns type T.

We've always generated it as a static function on demand, i.e. when we
generate a call.

Since we split up monolithic generated code into modules (commit
252dc3105f "qapi: Generate separate .h, .c for each module"), we do
this per module.  As noted in the commit message, this can result in
identical (static) qmp_marshal_output_T() in several modules.  Was
deemed not worth avoiding.

A bit later, we added 'if' conditionals to the schema language (merge
commit 5dafaf4fbc).

When a conditional definition uses a type, then its condition must
imply the type's condition.  We made this the user's responsibility.
Hasn't been an issue in practice.

However, the sharing of qmp_marshal_output_T() among commands
complicates matters.  To avoid both undefined function errors and
unused function warnings, qmp_marshal_output_T() must be defined
exactly when it's used.  It is used when any of the qmp_marshal_C()
calling it is defined, i.e. when any C's condition holds.

The generator uses T's condition instead.  To avoid both error and
warning, T's condition must be the conjunction of all C's conditions.

Unfortunately, this can be impossible:

* Conditional command returning a builtin type

  A builtin type cannot be conditional.  This is noted in a FIXME
  comment.

* Commands in multiple modules where the conjunction differs between
  modules

  An instance of this came up recently.  we have unconditional
  commands returning HumanReadableText.  If we add a conditional one
  to a module that does not have unconditional ones, compilation fails
  with "defined but not used".  If we make HumanReadableText
  conditional to fix this module, we break the others.

Instead of complicating the code to compute the conjunction, simplify
it: generate the output marshaling code right into qmp_marshal_C().

This duplicates it when multiple commands return the same type.  The
impact on code size is negligible: qemu-system-x86_64's text segment
grows by 1448 bytes.

71260a0120 scripts/checkpatch.pl: remove bogus patch prefix warning
Remove the 'patch prefix exists, appears to be a -p0 patch' warning
entirely as it is fundamentally flawed and can only produce false
positives.

Sometimes I create test files with names 'a' and 'b', and then get
surprised seeing this warning. It was not easy to understand where it
comes from.

How it works:
1. It extracts prefixes (a/, b/) from standard diff output
2. Checks if files/directories with these names exist in the project
   root
3. Warns if they exist, claiming it's a '-p0 patch' issue

This logic is wrong because:
- Standard diff/patch tools always use a/ and b/ prefixes by default
- The existence of files named 'a' or 'b' in the working directory is
  completely unrelated to patch format
- The working directory state may not correspond to the patch content
  (different commits, branches, etc.)
- In QEMU project, there are no single-letter files/directories in root,
  so this check can only generate false positives

The correct way to detect -p0 patches would be to analyze the path
format within the patch itself (e.g., absolute paths or paths without
prefixes), not check filesystem state.

So, let's finally drop it.

ac7a5f1b72 scripts/vmstate-static-checker: Fix deprecation warnings with latest argparse
The argparse.FileType() type has been deprecated in the latest argparse
version (e.g. the one from Fedora 43), now causing the test_bad_vmstate
functional test to fail since there are unexpected strings in the output.
Change the script to use pathlib.Path instead to fix the test_bad_vmstate
test and to be prepared for the future when the deprecated FileType gets
removed completely.

audio_register_model_with_cb() dropped "pci" from the name, since it

deprecated_register_soundhw() was actually not a function to be

bit host support is deprecated. As the extra packages where needed for

point keeping this in.

While the full expunging of 32 bit host support will probably be done
for 11.0 we can at least reduce the CI burden a bit now.

dd10dbe617 tests: Evict stale files in the functional download cache after a while
The download cache of the functional tests is currently only growing.
But sometimes tests get removed or changed to use different assets,
thus we should clean up the stale old assets after a while when they
are not in use anymore. So add a script that looks at the time stamps
of the assets and removes them if they haven't been touched for more
than half of a year. Since there might also be some assets around that
have been added to the cache before we added the time stamp files,
assume a default time stamp that is close to the creation date of this
patch, so that we don't delete these files too early (so we still have
all assets around in case we have to bisect an issue in the recent past
of QEMU).

b46b3818cf tests/functional: Provide GDB to the functional tests
The probe of GDB is done in 'configure' and the full path is passed to
meson.build via the -Dgdb=option.

Meson then can pass the location of GDB to the functional tests via an
environment variable: QEMU_TEST_GDB.

The registration-token method is being deprecated:

As a result we can drop a bunch of the descriptive stuff as that is
entered on the web UI. We don't need a secondary runner if we just
create one with both aarch64 and aarch32 tags.

4cc103081b scripts/ghes_inject: add a script to generate GHES error inject
Using the QMP GHESv2 API requires preparing a raw data array
containing a CPER record.

Add a helper script with subcommands to prepare such data.

Currently, only ARM Processor error CPER record is supported, by
using:
	$ ghes_inject.py arm

which produces those warnings on Linux:

[  705.032426] [Firmware Warn]: GHES: Unhandled processor error type 0x02: cache error
[  774.866308] {4}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 1

[  774.867962] {4}[Hardware Error]:    error_info: 0x000000000091000f
[  774.868124] {4}[Hardware Error]:     transaction type: Data Access

[  774.868465] {4}[Hardware Error]:     cache level: 2

[  774.868774] [Firmware Warn]: GHES: Unhandled processor error type 0x02: cache error

Such script allows customizing the error data, allowing to change
all fields at the record. Please use:

	$ ghes_inject.py arm -h

For more details about its usage.

1461752f0f tracetool/syslog: add Rust support
The syslog backend needs the syslog function from libc and the LOG_INFO enum
value; they are re-exported as "::trace::syslog" and "::trace::LOG_INFO"
so that device crates do not all have to add the libc dependency, but
otherwise there is nothing special.
