2023-06-07configure: check for $download value properlyMichal Privoznik
If configure was invoked with --disable-download and git submodules were not checked out a warning is produced and the configure script fails. But the $download variable (which reflects the enable/disable download argument) is checked for in a weird fashion: test -f "$download" = disabled Drop the '-f' to check for the actual value of the variable.

2023-06-06meson: subprojects: replace berkeley-{soft,test}float-3 with wrapsPaolo Bonzini
Unlike other subprojects, these require an overlay directory to include meson rules to build the libraries. The rules are basically lifted from tests/fp/meson.build, with a few changes to create platform.h and publish a dependency. The build defines are passed through a subproject option, and posted back to users of the library via the dependency's compile_args. The only remaining user of GIT_SUBMODULES and GIT_SUBMODULES_ACTION is roms/SLOF, which is used to build pc-bios/s390-ccw. All other roms submodules are only present to satisfy the license on pre-built firmware blobs. Best reviewed with --color-moved. Reviewed-by: Daniel P.

2023-06-06meson: subprojects: replace submodules with wrap filesPaolo Bonzini
Compared to submodules, .wrap files have several advantages: * option parsing and downloading is delegated to meson * the commit is stored in a text file instead of a magic entry in the git tree object * we could stop shipping external dependencies that are only used as a fallback, but not break compilation on platforms that lack them. For example it may make sense to download dtc at build time, controlled by --enable-download, even when building from a tarball. Right now, this patch does the opposite: make-release treats dtc like libvfio-user (which is not stable API and therefore hasn't found its way into any distros) and keycodemap (which is a copylib, for better or worse). dependency() can fall back to a wrap automatically. However, this is only possible for libraries that come with a .pc file, and this is not very common for libfdt even though the upstream project in principle provides it; it also removes the control that we provide with --enable-fdt={system,internal}. Therefore, the logic to pick system vs. internal libfdt is left untouched. --enable-fdt=git is removed; it was already a synonym for --enable-fdt=internal. Reviewed-by: Daniel P.

2023-06-06configure: rename --enable-pypi to --enable-download, control subprojects tooPaolo Bonzini
The behavior of --{enable,disable}-pypi is similar to that of -Dwrapmode={default,nodownload} respectively. In particular, in both cases a feature needs to be explicitly enabled for the dependency to be downloaded. So, use a single option to control both cases. Now, --enable-slirp will trigger cloning and building of libslirp if the .pc file is not found on the machine. Reviewed-by: Daniel P.

2023-06-06configure: remove --with-git= optionPaolo Bonzini
The scenario for which --with-git= was introduced was to use a SOCKS proxy such as tsocks. However, this was back in 2017 when QEMU's submodules used the git:// protocol, and it is not as important when using the "smart HTTP" backend; for example, neither "meson subprojects download" nor scripts/checkpatch.pl obey the GIT environment variable. So remove the knob, but test for the presence of git in the configure and git-submodule.sh scripts, and suggest using --with-git-submodules=validate + a manual invocation of git-submodule.sh when git does not work. Hopefully in the future the GIT environment variable will be supported by Meson.

2023-05-26configure: unset harmful environment variablesPaolo Bonzini
Apart from CLICOLOR_FORCE and GREP_OPTIONS, there are other variables that are listed in the Autoconf manual. While Autoconf neutralizes them very early, and assumes it does not (yet) run in a shell that has "unset", QEMU assumes that the user invoked configure under a POSIX shell, and therefore can simply use "unset" to clear them. CDPATH is particularly nasty because it messes up "cd ... && pwd". Reported-by: Juan Quintela <quintela@redhat.com> Cc: qemu-stable@nongnu.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Some scripts are invoked via the first "python3" binary in the PATH, because they are executable and their shebang line is "#! /usr/bin/env python3". To enforce usage of $(PYTHON), make them nonexecutable. Scripts invoked via meson need nothing else, and meson-buildoptions.py is already using $(PYTHON).

2023-05-18Python: Drop support for Python 3.6Paolo Bonzini
Python 3.6 was EOL 2021-12-31. Newer versions of upstream libraries have begun dropping support for this version and it is becoming more cumbersome to support. Avocado-framework and qemu.qmp each have their own reasons for wanting to drop Python 3.6, but won't until QEMU does. Versions of Python available in our supported build platforms as of today, with optional versions available in parentheses: openSUSE Leap 15.4: 3.6.15 (3.9.10, 3.10.2) CentOS Stream 8: 3.6.8 (3.8.13, 3.9.16) CentOS Stream 9: 3.9.13 Fedora 36: 3.10 Fedora 37: 3.11 Debian 11: 3.9.2 Alpine 3.14, 3.15: 3.9.16 Alpine 3.16, 3.17: 3.10.10 Ubuntu 20.04 LTS: 3.8.10 Ubuntu 22.04 LTS: 3.10.4 NetBSD 9.3: 3.9.13* FreeBSD 12.4: 3.9.16 FreeBSD 13.1: 3.9.16 OpenBSD 7.2: 3.9.16 Note: Our VM tests install 3.9 explicitly for FreeBSD and 3.10 for NetBSD; the default for "python" or "python3" in FreeBSD is 3.9.16. NetBSD does not appear to have a default meta-package, but offers several options, the lowest of which is 3.7.15. "python39" appears to be a pre-requisite to one of the other packages we request in tests/vm/netbsd. pip, ensurepip and other Python essentials are currently only available for Python 3.10 for NetBSD. CentOS and OpenSUSE support parallel installation of multiple Python interpreters, and binaries in /usr/bin will always use Python 3.6. However, the newly introduced support for virtual environments ensures that all build steps that execute QEMU Python code use a single interpreter. Since it is safe to under our supported platform policy, bump our minimum supported version of Python to 3.7. Signed-off-by: John Snow <jsnow@redhat.com> Reviewed-by: Daniel P.

2023-05-18configure: add --enable-pypi and --disable-pypiJohn Snow
In the event that there's no vendored source present and no sufficient version of $package can be found, we will attempt to connect to PyPI to install the package if '--disable-pypi' was not passed. This means that PyPI access is "enabled by default", but there are some subtleties that make this action occur much less frequently than you might imagine: (1) While --enable-pypi is the default, vendored source will always be preferred when found, making PyPI a fallback. This should ensure that configure-time venv building "just works" for almost everyone in almost every circumstance. (2) Because meson source is, at time of writing, vendored directly into qemu.git, PyPI will never be used for sourcing meson. (3) Because Sphinx is an optional dependency, if docs are set to "auto", PyPI will not be used to obtain Sphinx source as a fallback and instead docs will be disabled. If PyPI sourcing of sphinx is desired, --enable-docs should be passed to force the lookup. I chose this as the default behavior to avoid adding new internet lookups to a "default" invocation of configure.

If docs are set to "auto", attempt to locate Sphinx, but continue onward if it wasn't located.

2023-05-18configure: use 'mkvenv ensure meson' to bootstrap mesonJohn Snow
This commit changes how we detect and install meson. It notably removes '--meson='. Currently, configure creates a lightweight Python virtual environment unconditionally using the user's configured $python that inherits system packages. Temporarily, we forced the use of meson source present via git submodule or in the release tarball. With this patch, we restore the ability to use a system-provided meson: If Meson is installed in the build venv and meets our minimum version requirements, we will use that Meson. This includes a system provided meson, which would be visible via system-site packages inside the venv. In the event that Meson is installed but *not for the chosen Python interpreter*, not found, or of insufficient version, we will attempt to install Meson from vendored source into the newly created Python virtual environment. This vendored installation replaces both the git submodule and tarball source mechanisms for sourcing meson. As a result of this patch, the Python interpreter we use for both our own build scripts *and* Meson extensions are always known to be the exact same Python. As a further benefit, there will also be a symlink available in the build directory that points to the correct, configured python and can be used by e.g. manual tests to invoke the correct, configured Python unambiguously.

2023-05-18configure: create a python venv unconditionallyJohn Snow
This patch changes the configure script so that it always creates and uses a python virtual environment unconditionally. Meson bootstrapping is temporarily altered to force the use of meson from git or vendored source (as packaged in our source tarballs). A subsequent commit restores the use of distribution-vendored Meson.

2023-05-10block: compile out assert_bdrv_graph_readable() by defaultStefan Hajnoczi
reader_count() is a performance bottleneck because the global aio_context_list_lock mutex causes thread contention. Put this debugging assertion behind a new ./configure --enable-debug-graph-lock option and disable it by default. The --enable-debug-graph-lock option is also enabled by the more general --enable-debug option.

2023-04-20configure: Honour cross-prefix when finding ObjC compilerPeter Maydell
Currently when configure picks an ObjectiveC compiler it doesn't pay attention to the cross-prefix. This isn't a big deal in practice, because we only use ObjC on macos and you can't cross-compile to macos. But it's a bit inconsistent. Rearrange the handling of objcc in configure so that we do the same thing that we do with cc and cxx. This means that the logic for picking the ObjC compiler goes from: if --objcc is specified, use that otherwise if clang is available, use that otherwise use $cc to: if --objcc is specified, use that otherwise if --cross-prefix is specified, use ${cross_prefix}clang otherwise if clang is available, use that otherwise use $cc Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1185 Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-Id: <20230418161554.744834-1-peter.maydell@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-04-20configure: Avoid -Werror=maybe-uninitializedAkihiko Odaki
The configure script used to compile some code which dereferences memory with ubsan to verify the compiler can link with ubsan library which detects dereferencing of uninitialized memory. However, as the dereferenced memory was allocated in the same code, GCC can statically detect the unitialized memory dereference and emit maybe-uninitialized warning. If -Werror is set, this becomes an error, and the configure script incorrectly thinks the error indicates the compiler cannot use ubsan. Fix this error by replacing the code with another function which adds 1 to a signed integer argument. This brings in ubsan to detect if it causes signed integer overflow. As the value of the argument cannot be statically determined, the new function is also immune to compiler warnings.

2023-04-20build-sys: prevent meson from downloading wrapped subprojectsMarc-André Lureau
The following patches are going to introduce meson wrap dependencies, which is a solution to download and build missing dependencies. The QEMU build-system will do network access with no way to avoid the fallback. As a start, hardcode "--wrap-mode=nodownload" in configure, so that wraps would be used only after a conscious decision of the user to use "meson subprojects download" (before running configure).

2023-03-28util: import GTree as QTreeEmilio Cota
The only reason to add this implementation is to control the memory allocator used. Some users (e.g. TCG) cannot work reliably in multi-threaded environments (e.g. forking in user-mode) with GTree's allocator, GSlice. See https://gitlab.com/qemu-project/qemu/-/issues/285 for details. Importing GTree is a temporary workaround until GTree migrates away from GSlice. This implementation is identical to that in glib v2.75.0, except that we don't import recent additions to the API nor deprecated API calls, none of which are used in QEMU. I've imported tests from glib and added a benchmark just to make sure that performance is similar. Note: it cannot be identical because (1) we are not using GSlice, (2) we use different compilation flags (e.g. -fPIC) and (3) we're linking statically. $ cat /proc/cpuinfo| grep 'model name' | head -1 model name : AMD Ryzen 7 PRO 5850U with Radeon Graphics $ echo '0' | sudo tee /sys/devices/system/cpu/cpufreq/boost $ tests/bench/qtree-bench Tree Op 32 1024 4096 131072 1048576 ------------------------------------------------------------------------------------------------ GTree Lookup 83.23 43.08 25.31 19.40 16.22 QTree Lookup 113.42 (1.36x) 53.83 (1.25x) 28.38 (1.12x) 17.64 (0.91x) 13.04 (0.80x) GTree Insert 44.23 29.37 25.83 19.49 17.03 QTree Insert 46.87 (1.06x) 25.62 (0.87x) 24.29 (0.94x) 16.83 (0.86x) 12.97 (0.76x) GTree Remove 53.27 35.15 31.43 24.64 16.70 QTree Remove 57.32 (1.08x) 41.76 (1.19x) 38.37 (1.22x) 29.30 (1.19x) 15.07 (0.90x) GTree RemoveAll 135.44 127.52 126.72 120.11 64.34 QTree RemoveAll 127.15 (0.94x) 110.37 (0.87x) 107.97 (0.85x) 97.13 (0.81x) 55.10 (0.86x) GTree Traverse 277.71 276.09 272.78 246.72 98.47 QTree Traverse 370.33 (1.33x) 411.97 (1.49x) 400.23 (1.47x) 262.82 (1.07x) 78.52 (0.80x) ------------------------------------------------------------------------------------------------ As a sanity check, the same benchmark when Glib's version is >= $glib_dropped_gslice_version (i.e. QTree == GTree): Tree Op 32 1024 4096 131072 1048576 ------------------------------------------------------------------------------------------------ GTree Lookup 82.72 43.09 24.18 19.73 16.09 QTree Lookup 81.82 (0.99x) 43.10 (1.00x) 24.20 (1.00x) 19.76 (1.00x) 16.26 (1.01x) GTree Insert 45.07 29.62 26.34 19.90 17.18 QTree Insert 45.72 (1.01x) 29.60 (1.00x) 26.38 (1.00x) 19.71 (0.99x) 17.20 (1.00x) GTree Remove 54.48 35.36 31.77 24.97 16.95 QTree Remove 54.46 (1.00x) 35.32 (1.00x) 31.77 (1.00x) 24.91 (1.00x) 17.15 (1.01x) GTree RemoveAll 140.68 127.36 125.43 121.45 68.20 QTree RemoveAll 140.65 (1.00x) 127.64 (1.00x) 125.01 (1.00x) 121.73 (1.00x) 67.06 (0.98x) GTree Traverse 278.68 276.05 266.75 251.65 104.93 QTree Traverse 278.31 (1.00x) 275.78 (1.00x) 266.42 (1.00x) 247.89 (0.99x) 104.58 (1.00x) ------------------------------------------------------------------------------------------------ Signed-off-by: Emilio Cota <cota@braap.org> Message-Id: <20230205163758.416992-2-cota@braap.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
