NetBSD 10.1 has been released since more than a year, so it's time to
update our VM to that version.
Apart from the usual changes in the installation process, we also have
to disable the installation of the "jpeg" package now, otherwise the
package installation fails with an error message like this:
pkg_add: jpeg-9fnb1: conflicts with `libjpeg-turbo-[0-9]*', and
`libjpeg-turbo-3.1.3' is installed.
We also have to drop the executable bits from scripts/qemu-plugin-symbols.py
to force meson to use the detected Python interpreter instead of executing
the file directly (which tries to use the Python interpreter from the file's
shebang line).

probably intended to exclude tests/tcg/plugins/, which is caught
by the tests/tcg exclude pattern anyway
Add to the exclude list:
* rust/ -- the headers in here are purely for input to bindgen
* target/hexagon has some standalone tools used at build time
* linux-user/gen-vsdo.c -- another standalone tool
* linux-user/mips64/elfload.c just includes mips/elfload.c
* scripts/xen-detect.c is feature-detection code used by meson.build

We currently have two mechanisms for excluding files:
* the REGEXFILE which excludes by regex
* special cases in the "loop over each file" which make
us skip the file
Roll all the "skip this" cases into REGEXFILE, so we use
a single mechanism for identifying which files to exclude.

Currently we have a single extended regular expression defining
files that clean-includes should ignore. This is now very long
and awkward to read and edit.
Switch to having a list of newline-separated EREs that we write
to a file for grep's -f option, so we can express them more
legibly in the shell script. We allow for comments in the
regex list, which lets us document why we have put the

Commit 500131154d ("exec.c: Add new address_space_ld*/st*
functions") added a new API to fix a shortcoming of the
ld/st*_phys() API, which does blind bus access, not reporting
failure (and it also allow to provide transaction attributes).
Later commit 42874d3a8c ("Switch non-CPU callers from ld/st*_phys
to address_space_ld/st*") automatically converted the legacy uses
to the new API, not precising transaction attributes
(MEMTXATTRS_UNSPECIFIED) and ignoring the transation result (passing
NULL pointer as MemTxResult).
While this is a faithful replacement, without any logical change,
we later realized better is to not use MEMTXATTRS_UNSPECIFIED or
NULL MemTxResult, and adapt each call site on a pair basis, looking
at the device model datasheet to do the correct behavior (which is
unlikely to ignore transaction failures).
Since this is quite some work, we defer that to device model
maintainers. Meanwhile we introduce a definition, to allow a
target which removed all legacy API call to prohibit further
legacy API uses, named "TARGET_NOT_USING_LEGACY_LDST_PHYS_API".
Since all targets should be able to check this definition, we
take care to not poison it.

With the bump to Meson 1.10.0, C objects can be passed to rust targets.
This way, the Rust libstd will be added by rustc itself in its final
linker invocation. Use that to eliminate the staticlib and allow
dynamic linking with libstd (also introduced by Meson 1.9.0, but not
for staticlib crates due to lack of support in rustc).
The main() function is still provided by C, which is possible by
declaring the main source file of the Rust executable (which is
still created by scripts/rust/rust_root_crate.sh) as #![no_main].

Implement DTrace/SystemTap SDT by emitting the following:
- The probe crate's probe!() macro is used to emit a DTrace/SystemTap
SDT probe.
- Every trace event gets a corresponding trace_<name>_enabled() -> bool
generated function that Rust code can use to avoid expensive
computation when a trace event is disabled. This API works for other
trace backends too.
`#[allow(dead_code)]` additions are necessary for QEMU's dstate in
generated trace-<dir>.rs files since they are unused by the dtrace
backend. `./configure --enable-trace-backends=` can enable multiple
backends, so keep it simple and just silence the warning instead of
trying to detect the condition when generating the dstate code can be
skipped.
The tracetool tests are updated. Take a look at
tests/tracetool/dtrace.rs to see what the new generated code looks like.

As an eMMC block device image may consist of more than just the user
data partition, provide a helper script that can compose the image from
boot partitions, an RPMB partition and the user data image. The script
also does the required size validation and/or rounding.

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.

The detection of example and literal blocks isn't quite correct, but
it works well enough, and we can improve on top.

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.

[Commit message typos fixed]
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.

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.
