OSS is a kernel API, so the option should not be needed. The library
is used on NetBSD, where OSS is emulated, so keep the variable.

Not just NetBSD. You could --audio-drv-list=oss and --oss-lib= to specify
the library to link with.
However, I am not sure this is still needed. It was introduced in:
commit 2f6a1ab038eefd6e5a9cfc8ec49435f6ad025812

Yes, but the question is who would use --oss-lib. And secondarily, if
the answer is not "no one", whether they would be accomodated better by
a change to QEMU itself.
For example OpenBSD support was removed in 2013:
Remove OSS support for OpenBSD
Remove the OSS support for OpenBSD. The OSS API has not been usable
for quite some time.

However, if it came back from the dead, one could just
if not cc.has_header('sys/soundcard.h')
# not found
- elif targetos == 'netbsd'
+ elif targetos in ['netbsd', 'openbsd']
oss = cc.find_library('ossaudio', required: get_option('oss'),
kwargs: static_kwargs)
else
instead of using something like --oss-lib.

Ever since winwaveaudio was removed in 2015, CONFIG_AUDIO_WIN_INT
is only set if dsound is in use, so use CONFIG_AUDIO_DSOUND directly.

This brings a change that makes audio drivers more similar to all
other modules. All drivers are built by default, while
--audio-drv-list only governs the default choice of the audio driver.
Meson options are added to disable the drivers, and the next patches
will fix the help messages and command line options, and especially
make the non-default drivers available via -audiodev.

All drivers are now built by default if the corresponding libraries
are available, similar to how all other modules behave;
--audio-drv-list only governs the default choice of the audio driver.
Adjust the CONFIG_AUDIO_* preprocessor symbols so that they are
based on library availability rather than --audio-drv-list, so that
the tests and -audiodev help follow the new logic.

This bit doesn't look quite right, with the if_true.

It looks silly but it works ("when: []" is always-true, just like in
python all([]) is true). I'll remove the if_true in v2.

and why not keep the one-liner version?:

It would link libaio even in files that don't use it. The stub is used
by those files that get util/async.c via libqemuutil, but not
block/linux-aio.c.
This particular stub (and the equivalent io_uring one) is a bit silly
though.
Someone should check exactly which files get which stub, maybe there are
opportunities for simplifications. For example if a stub is only used
by the unit tests, we might as well move more code to libqemuutil and
remove the stub.

The options were deprecated in 6.0. That said, we do not really have a
formal deprecation cycle for build-time changes, since they do not affect
users.

Options such as "--enable-capstone=git" do not make much sense when building
from a tarball. Accept "internal" for consistency with the meson options.

Prepare the configure script and Makefile for automatically generated
help and parsing.
Because we need to run the script to generate the full help, we
cannot rely on the user supplying the path to a Python interpreter
with --python; therefore, the introspection output is parsed into
shell functions and stored in scripts/. The converter is written
in Python as standard for QEMU, and this commit contains a stub.

Looks like a good approach to me! I've just got two questions below...

Why the detour via this wrapper and $(_meson_option_parse) ? Couldn't you
simply add the stuff directly to $meson_options in _meson_option_parse() ?

Mostly to keep the amount of shell-in-Python code as small as possible.
Also, I liked that the generated shell code was completely independent
of the configure script, did not use global variables and did not have
to know that "meson_options" is tied to the way the "run_meson" shell
function uses eval.

Yes, of course.

* [PATCH 24/24] configure: automatically parse command line for meson -D options

Right now meson_options.txt lists about 90 options. Each option
needs code in configure to parse it and pass the option down to Meson as
a -D command-line argument; in addition the default must be duplicated
between configure and meson_options.txt. This series tries to remove
the code duplication by generating the case statement for those --enable
and --disable options, as well as the corresponding help text.
About 80% of the options can be handled completely by the new mechanism.
Eight meson options are not of the --enable/--disable kind. Six more need
to be parsed in configure for various reasons documented in the patch,
but they still have their help automatically generated.
The advantages are:
- less code in configure
- parsing and help is more consistent (for example --enable-blobs was
not supported)
- options are described entirely in one place, meson_options.txt.
This make it more attractive to use Meson options instead of
hand-crafted configure options and config-host.mak
A few options change name: --enable-tcmalloc and --enable-jemalloc
become --enable-malloc={tcmalloc,jemalloc}; --disable-blobs becomes
--disable-install-blobs; --enable-trace-backend becomes
--enable-trace-backends.

+The configure script automatically recognizes
+command line options for which a same-named Meson option exists;
+dashes in the command line are replaced with underscores.
+Many checks on the compilation environment are still found in configure
+rather than `meson.build`, but new checks should be added directly to
+`meson.build`.
+Patches are also welcome to move existing checks from the configure
+phase to `meson.build`. When doing so, ensure that `meson.build` does
+not use anymore the keys that you have removed from `config-host.mak`.
+Typically these will be replaced in `meson.build` by boolean variables,
+``get_option('optname')`` invocations, or `dep.found()` expressions.
+In general, the remaining checks have little or no interdependencies,
+so they can be moved one by one.

+Adding checks
+-------------
+
+New checks should be added to Meson. Compiler checks can be as simple as
+the following::
+
+ config_host_data.set('HAVE_BTRFS_H', cc.has_header('linux/btrfs.h'))
+
+A more complex task such as adding a new dependency usually
+comprises the following tasks:
+
+ - Add a Meson build option to meson_options.txt.
+
+ - Add code to perform the actual feature check.
+
+ - Add code to include the feature status in `config-host.h`
+
+ - Add code to print out the feature status in the configure summary
+ upon completion.
+
+Taking the probe for SDL2_Image as an example, we have the following
+in ``meson_options.txt``::
+
+ option('sdl_image', type : 'feature', value : 'auto',
+ description: 'SDL Image support for icons')
+
+Unless the option was given a non-``auto`` value (on the configure
+command line), the detection code must be performed only if the
+dependency will be used::
+
+ sdl_image = not_found
+ if not get_option('sdl_image').auto() or have_system
+ sdl_image = dependency('SDL2_image', required: get_option('sdl_image'),
+ method: 'pkg-config',
+ static: enable_static)
+ endif
+
+This avoids warnings on static builds of user-mode emulators, for example.
+Most of the libraries used by system-mode emulators are not available for
+static linking.
+
+The other supporting code is generally simple::
+
+ # Create config-host.h (if applicable)
+ config_host_data.set('CONFIG_SDL_IMAGE', sdl_image.found())
+
+ # Summary
+ summary_info += {'SDL image support': sdl_image.found()}
+
+For the configure script to parse the new option, the
+``scripts/meson-buildoptions.sh`` file must be up-to-date; ``make
+For the configure script to parse the new option, the ``meson-buildoptions.json``
+update-buildoptions`` (or just `make`) will take care of updating it.

From the commit message:
"A few options change name: --enable-tcmalloc and --enable-jemalloc
become --enable-malloc={tcmalloc,jemalloc}; --disable-blobs becomes
--disable-install-blobs; --enable-trace-backend becomes
--enable-trace-backends".
I'll add some code for backwards compatibility.

Right, I got tired of reviewing at this point to read the whole thing.
