libcamera v0.4.0
The abi-compliance-checker reports that there is both ABI and API breakage in this release. Binary compatibility: 91.2% Source compatibility: 98.9% Total binary compatibility problems: 69, warnings: 0 Total source compatibility problems: 9, warnings: 0 This is not too surprising as this was the reason for the extra delay holding up this release, and as such this release bumps the SONAME to 0.4 accordingly. The majority of the ABI breakages are around the public API for Control handling and definitions, which have caused underlying identifiers to be changed, and the reuqired storage for controls has increased. I hope that grouping the expected ABI and API breakages and delaying this release will allow a longer stability on the 0.4 series but as we are developing rapidly this can not be guaranteed, though we aim to minimise disruption to distributions and applications whereever possible. This release brings in 253 commits, with substantial development on image control and tuning features for IPA and Pipeline handlers supporting libipa, as well as integrating libipa support for IPA handling on the ARM Mali-C55 ISP. A new 'Virtual Pipeline Handler' has been introduced to support more testing in CI and virtual environments. Gstreamer has had some interesting development to rework expressing the full control set from libcamera using auto generation from the full control descriptors. A key and notable change in this release too is that the softISP is now moving towards utilising the libipa implementaitons which will enable future tuning and image control capabilities, and should also support future development on a GPU-ISP implementation for GPU-accelerated handling. I do believe this work may have introduced an oscillation regression in the AEGC which will need to be investigated and fixed in the near future, but I don't want to hold up progressing the ABI updates at this stage. The i.MX8MP can now make full use of the DW100 Dewarp Engine for full rotation and digital zoom capabilities. Raspberry Pi systems now have improved support for the OV7251, IMX462, and IMX327 Sensors, and libipa platforms can now make use of the GalaxyCore gc05a2 and gc08a3 Image sensors. The following commits in this release relate to either a bug fix or an improvement to an existing commit. - ipa: rpi: Use std::abs() - Reported-by: Maarten Lankhorst <dev@lankhorst.se> - libcamera: rkisp1: Clamp stream configuration to ISP limit on raw path - Fixes: |

test: py: LD_PRELOAD the C++ standard library when using ASan
When the ASan runtime is linked using --as-needed, its dependency on the
C++ standard library is stripped. This results to a failure to properly
handled exceptions when a C++ dynamically loaded .so is used, as in the
Python unit tests that load the libcamera Python module:

meson: Store controls and properties YAML files in variables
When generating control headers, the YAML files to be used are determined dynamically based on the selected pipeline handlers. As part of this process, the build system populates an array of meson File objects used as an input for the control headers generation custom target, as well as an array of file names (as strings). The file names array is later used to generate the control source files for the libcamera core, as well as the source code for controls support in the Python bindings. Both of the source code generators manually turn the array of file names into File objects. This duplicates code and reduces readability. A third similar implementation has also been proposed to generate control support sources in the GStreamer element, making the issue worse. To simplify this, store File objects instead of file names in the controls_files array. As the meson configuration summary doesn't support File objects, create a separate controls_files_names to store the file names for that sole purpose. The exact same process occurs for properties, address them the same way.

meson: Enable simple pipeline handler on all platforms by default
The simple pipeline handler is enabled by default on arm platforms only,
as it used to support arm SoCs only. Now that support for the IPU6 has

platforms as well. Fix it.

v4l2: v4l2_compat: Fix ioctl() prototype with musl C library
The musl C library, as well as the POSIX standard, define the ioctl() function's request argument as an int. glibc and uclibc, on the other hand, define it as an unsigned long. This difference between the function prototype and the implementation in the V4L2 adaptation layer causes a compilation error with musl. Fix it by detecting the function prototype and declaring the libcamera ioctl() handler accordingly.

Revert "meson: Deprecate bitwise operations between different enumeration type"
Enabling -Wdeprecated-enum-enum-conversion by default turned out to be a
too hasty decision. It causes compilation failures with Qt headers prior
to Qt v5.15.8. As the previous LTS versions of Debian and Ubuntu ship
older Qt versions, those errors cause real inconvenience to users.

meson: Tag all installed files
Meson uses tags to sort installed files in categories, and makes it possible to install a subset of the files using the '--tags' argument to 'meson install'. This is typically used by distributions to split the runtime, development and documentation files into separate packages. By default, meson tries to guess the correct tag for installed files, but can't always do so properly. Mark the install targets that meson can't guess with the correct install_tag. As the feature has been introduced in meson 0.60, bump the minimum meson version. The latest LTS release of all major distributions that libcamera currently targets ship a recent enough meson version.

build: controls: Rework how controls and properties are generated
Add support for using separate YAML files for controls and properties generation. The mapping of vendor/pipeline handler to control file is done through the controls_map variable in include/libcamera/meson.build. This simplifies management of vendor control definitions and avoids possible merge conflicts when changing the control_ids.yaml file for core and draft controls. With this change, libcamera and draft controls and properties files are designated the 'libcamera' vendor tag. In this change, we also rename control_ids.yaml -> control_ids_core.yaml and property_ids.yaml -> property_ids_core.yaml to designate these as core libcamera controls.

The abi-compatibility report can now be generated with the new utility './utils/abi-compat.sh'.

This is now handled as a Span<StreamRole> to prevent unnecessary allocations and copies. - CameraManager::addCamera ( std::shared_ptr<struct Camera> camera, std::vector<unsigned long>const& devnums ) - CameraManager::get ( dev_t devnum ) - CameraManager::removeCamera ( std::shared_ptr<struct Camera> camera ) These functions of the CameraManager were for use exclusively by the V4L2 adaptation layer, and not intended for use by applications. This has now been reworked to use the new SystemDevices and the redundant functions removed. The ABI/API breakages have been introduced by: |

libcamera: Add option to configure udev support
libcamera uses udev to support hotplug (and unplug) detection. This is an optional feature, which gets selected automatically if udev is available. Users may however want to build libcamera without hotplug detection, even if udev is available on the system. Add a new feature option to control udev support. The default value is auto, which retains the existing behaviour.

Documentation: Add predefined macros from config.h to Doxyfile
libcamera creates a config.h file with predefined macros, and instructs the compiler to include it implicitly with the -include argument. Doxygen has no support for implicit inclusion of headers, but has a PREDEFINED configuration option for its preprocessor that lists predefined macros. Populate it with the values from the config_h configuration data object that is used for generate the config.h file, to ensure that documentation matches the configuration options libcamera has been built with.

pipeline: ipa: raspberrypi: Refactor and move the Raspberry Pi code
Split the Raspberry Pi pipeline handler and IPA source code into common
and VC4/BCM2835 specific file structures.
For the pipeline handler, the common code files now live in
src/libcamera/pipeline/rpi/common/
and the VC4-specific files in src/libcamera/pipeline/rpi/vc4/.
For the IPA, the common code files now live in
src/ipa/rpi/{cam_helper,controller}/
and the vc4 specific files in src/ipa/rpi/vc4/. With this change, the
camera tuning files are now installed under share/libcamera/ipa/rpi/vc4/.
To build the pipeline and IPA, the meson configuration options have now
changed from "raspberrypi" to "rpi/vc4":

meson: Ignore -Wredundant-move with gcc-13 and newer
Starting from 13.1, gcc implements the C++23 version of automatic move from local variables in return statements (see https://en.cppreference.com/w/cpp/language/return). As a result, some previously required explicit `std::move()` in return statements generate warnings. This is the case when a function returns an object whose type is a class derived from the class type the function returns: struct U { }; struct T : U { }; U f() { T t; return t; } Up to C++20, the automatic move from local variables selects the move constructor of class U, which is not the move constructor of the expression. Overload resolution is then performed a second time, with t considered as an lvalue. An explicit `std::move(t)` is needed in the return statement to select the U move constructor. Starting from C++23, `t` is treated as an xvalue, and the U move constructor is selected without the need for an explicit `std::move(t)`. An explicit `std:move()` then generates a redundant-move warning, as in the valueOrTuple() function in src/py/libcamera/py_helpers.cpp. Omitting the `std::move()` silences the warning, but selects the copy constructor of U with older gcc versions and with clang, which negatively impacts performance. The easiest fix is to disable the warning. With -Wpessimizing-move enabled, the compiler will still warn of pessimizing moves, only the redundant but not pessimizing moves will be ignored.

meson: Fix git version parsing
When extracting the build metadata from the git version, we use the
string strip() method to remove the version prefix. This is incorrect,
as the strip() method takes a set of characters to be removed, not a
literal string. Fix it by splitting the git version string on the '+'
character and keeping the suffix.

meson: Rework automatic pipeline selection
The supported pipelines are listed in three places: the meson_options.txt file, the defined array when a user selects -Dpipelines="all", and arrays defined when the default -Dpipelines="auto" is selected. This can be hard to maintain and error prone. Rework the definition of pipeline selection to a single table which specifies the architecture(s) that the pipeline handler supports and iterate it to handle the special cases for 'all', 'auto' and 'test'. The current behaviour such that 'all' takes precedence over 'auto' is maintained, and 'test' is now extended such that additional test pipeline handlers can easily be introduced. The existing implementation defines the i.MX8-ISI and RKISP1 pipeline handlers as only supported by 'aarch64'. This conversion changes the behaviour such that those pipeline handlers are now supported on both 'arm' and 'aarch64' as each of those platforms could support a 32-bit ARM build.

libcamera: base: utils: Support C libraries lacking locale support
Not all C libraries include support for locale objects (locale_t) and
the strto*_l() family of functions. A notable example is uClibc that can
be compiled with a hardcoded "C" locale. Compilation then fails as the
newlocale(), freelocale() and strtod_l() functions are not defined.
Fix the compilation breakage by checking for the availability of the
locale_t type, and fall back to strtod() when the type isn't available.
This may not lead to the correct result if support for locale objects
isn't available and the locale isn't hardcoded to "C", but that is such
a corner case that we will likely never encounter it.

meson: Rewrite .replace usage
Meson introduces a .replace() method in version 0.58.0. However we aim to restrict ourselves to 0.56 meson features, as released by Debian stable. The recent introduction of release management infrastructure makes use of the .replace() method to fix up the version string when there is a mis-match between the release version and any (lack) of tags in the git version description. This breaks when built on systems with only meson 0.56. Refactor this to use a concatenation of the project version and a stripped git version to regenerate the full source version string that will be reported by libcamera.

meson: Shared Object version handling
The libcamera project is not yet ready to declare ABI nor API stability, but it will benefit the community to be able to provide more regular release cycles to determine 'versioned' points of history. Ideally, these releases will be made at any ABI breakage, but can be made at arbitary time based points along the way. To support releases which may not be ABI stable, declare the soversion of both the libcamera and libcamera-base library to be dependant upon both the major minor and patch component of the project version. As part of this, introduce a new 'Versions' summary section to highlight the different version components that may become apparent within any given build. Bumping versions may leave dangling libcamera.so.* symlinks in build directories. This will confuse Doxygen which will print during its directory scanning phase a warning that the symlink can't be read. As we don't need Doxygen to follow symlinks, disable it with EXCLUDE_SYMLINKS.
