gio.pc variable is a bit bogus in context of cross-compilation, since it
contains an absolute path, relative to the sysroot directory. On Fedora, it ends
up as:
/usr/x86_64-w64-mingw32/sys-root/mingw/lib/pkgconfig/usr/bin/gdbus-codegen
path which does not exist because it is not shipped by Fedora mingw
packages.
Instead, we can rely on meson find_program() behaviour to do a better
job based on its search order and capabilities.

How to build:
1. Configure a QEMU build with:
--enable-system --target-list=aarch64-softmmu --enable-rust
2. Launching a VM with qemu-system-aarch64 should use the Rust version

Include the correct path and arguments to rustc in the native
and cross files (native compilation is needed for procedural
macros).
Based on the host architecture and OS, the compiler and optionally the argument
to --cpu, the Rust target triple can be detected automatically for either a
native or a cross compiler.
In general, it is only a matter of translating the architecture and OS, and
adding a machine to form the triple, but there are some special cases (e.g.
detecting soft vs. hard floating point on ARM) and some inconsistencies.

Since quite a while MSYS2 now supports Clang as a compiler, too.
Unfortunately, this compiler is lacking the __attribute__((gcc_struct))
that we need for compiling on Windows. But since the compiler is
available now, some people started to use it to compile QEMU on MSYS2,
apparently ignoring the compiler warnings (see for example the ticket at
https://gitlab.com/qemu-project/qemu/-/issues/2476 ). These builds are
likely broken in a couple of spots, so let's make sure that we rather
bail out early in the configuration phase instead of allowing the build
to succeed with warnings.

Upstream clang 18 (and backports to clang 17 in Fedora and RHEL)
implemented support for __attribute__((cleanup())) in its Thread Safety
Analysis, so we can now actually have a proper implementation of
WITH_GRAPH_RDLOCK_GUARD() that understands when we acquire and when we
release the lock.
-Wthread-safety is now only enabled if the compiler is new enough to
understand this pattern. In theory, we could have used some #ifdefs to
keep the existing basic checks on old compilers, but as long as someone
runs a newer compiler (and our CI does), we will catch locking problems,
so it's probably not worth keeping multiple implementations for this.
The implementation can't use g_autoptr any more because the glib macros
define wrapper functions that don't have the right TSA attributes, so
the compiler would complain about them. Just use the cleanup attribute
directly instead.

Introduce a privileged helper to access RAPL MSR.
The privileged helper tool, qemu-vmsr-helper, is designed to provide
virtual machines with the ability to read specific RAPL (Running Average
Power Limit) MSRs without requiring CAP_SYS_RAWIO privileges or relying
on external, out-of-tree patches.
The helper tool leverages Unix permissions and SO_PEERCRED socket
options to enforce access control, ensuring that only processes
explicitly requesting read access via readmsr() from a valid Thread ID
can access these MSRs.
The list of RAPL MSRs that are allowed to be read by the helper tool is
defined in rapl-msr-index.h. This list corresponds to the RAPL MSRs that
will be supported in the next commit titled "Add support for RAPL MSRs
in KVM/QEMU."
The tool is intentionally designed to run on the Linux x86 platform.
This initial implementation is tailored for Intel CPUs but can be
extended to support AMD CPUs in the future.

Rather than creating stubs for every command that just return
QERR_UNSUPPORTED, use 'if' conditions in the QAPI schema to
fully exclude generation of the commands on other UNIX.
The command will be rejected at QMP dispatch time instead,
avoiding reimplementing rejection by blocking the stub commands.
This changes the error message for affected commands from
{"class": "CommandNotFound", "desc": "Command FOO has been disabled"}
to
{"class": "CommandNotFound", "desc": "The command FOO has not been found"}
This has the additional benefit that the QGA protocol reference
now documents what conditions enable use of the command.

Add accelerated cursor composition to ui/cocoa. This does not only
improve performance for display devices that exposes the capability to
the guest according to dpy_cursor_define_supported(), but fixes the
cursor display for devices that unconditionally expects the availability
of the capability (e.g., virtio-gpu).
The common pattern to implement accelerated cursor composition is to
replace the cursor and warp it so that the replaced cursor is shown at
the correct position on the guest display for relative pointer devices.
Unfortunately, ui/cocoa cannot do the same because warping the cursor
position interfers with the mouse input so it uses CALayer instead;
although it is not specialized for cursor composition, it still can
compose images with hardware acceleration.

The non-standard .fa library suffix breaks the link source
de-duplication done by Meson so drop it.
The lack of link source de-duplication causes AddressSanitizer to
complain ODR violations, and makes GNU ld abort when combined with
clang's LTO.
Fortunately, the non-standard suffix is not necessary anymore for
two reasons.
First, the non-standard suffix was necessary for fork-fuzzing.
Meson wraps all standard-suffixed libraries with --start-group and
--end-group. This made a fork-fuzz.ld linker script wrapped as well and
broke builds. Commit d2e6f9272d ("fuzz: remove fork-fuzzing
scaffolding") dropped fork-fuzzing so we can now restore the standard
suffix.
Second, the libraries are not even built anymore, because it is
possible to just use the object files directly via extract_all_objects().
The occurences of the suffix were detected and removed by performing
a tree-wide search with 'fa' and .fa (note the quotes and dot).

This reverts commit 3eacf70bb5.
It was only needed because of duplicate objects caused by
declare_dependency(link_whole: ...), and can be dropped now
that meson.build specifies objects and dependencies separately
for the internal dependencies.

We used to request declare_dependency() to link_whole static libraries.
If a static library is a thin archive, GNU ld keeps all object files
referenced by the archive open, and sometimes exceeds the open file limit.
Another problem with link_whole is that suboptimal handling of nested
dependencies.
link_whole by itself does not propagate dependencies. In particular,
gnutls, a dependency of crypto, is not propagated to its users, and we
currently workaround the issue by declaring gnutls as a dependency for
each crypto user. On the other hand, if you write something like
libfoo = static_library('foo', 'foo.c', dependencies: gnutls)
foo = declare_dependency(link_whole: libfoo)
libbar = static_library('bar', 'bar.c', dependencies: foo)
bar = declare_dependency(link_whole: libbar, dependencies: foo)
executable('prog', sources: files('prog.c'), dependencies: [foo, bar])
hoping to propagate the gnutls dependency into bar.c, you'll see a
linking failure for "prog", because the foo.c.o object file is included in
libbar.a and therefore it is linked twice into "prog": once from libfoo.a
and once from libbar.a. Here Meson does not see the duplication, it
just asks the linker to link all of libfoo.a and libbar.a into "prog".
Instead of using link_whole, extract objects included in static libraries
and pass them to declare_dependency(); and then the dependencies can be
added as well so that they are propagated, because object files on the
linker command line are always deduplicated.
This requires Meson 1.1.0 or later.

In order to define libqemuutil symbols that are requested by block modules,
QEMU currently uses a combination of the "link_depends" argument of
libraries (which is propagated into dependencies, but not available in
dependencies) and the "link_args" argument of declare_dependency()
(which _is_ available in static_library, but probably not used for
historical reasons only).
Unfortunately the link_depends will not be propagated into the
"block" dependency if it is defined using
declare_dependency(objects: ...); and it is not possible to
add it directly to the dependency because the keyword argument
simply is not available.
The only solution, in order to switch to defining the dependency
without using "link_whole" (which has problems of its own, see
https://github.com/mesonbuild/meson/pull/8151#issuecomment-754796420),
is unfortunately to add the link_args and link_depends to the
executables directly; fortunately there is just four of them.
It is possible (and I will look into it) to add "link_depends"
to declare_dependency(), but it probably will be a while before
QEMU can use it.

Add a Meson option to configure which x86-64 instruction
set to use. QEMU will now default to x86-64-v1 + cmpxchg16b for
64-bit builds (that corresponds to a Pentium 4 for 32-bit builds).
The baseline can be tuned down to Pentium Pro for 32-bit builds (with
-Dx86_version=0), or up as desired.

The point of CPU_CFLAGS is really just to select the appropriate multilib,
for example for library linking tests, and -mcx16 is not needed for
that purpose.
Furthermore, if -mcx16 is part of QEMU's choice of a basic x86_64
instruction set, it should be applied to cross-compiled x86_64 code too;
it is plausible that tests/tcg would want to cover cmpxchg16b as well,
for example. In the end this makes just as much sense as a per sub-build
tweak, so move the flag to meson.build and cross_cc_cflags_x86_64.
This leaves out contrib/plugins, which would fail when attempting to use
__sync_val_compare_and_swap_16 (note it does not do yet); while minor,
this *is* a disadvantage of this change. But building contrib/plugins
with a Makefile instead of meson.build is something self-inflicted just
for the sake of showing that it can be done, and if this kind of papercut
started becoming a problem we could make the directory part of the meson
build. Until then, we can live with the limitation.
