2023-01-31pipeline: raspberrypi: Add a parameter to disable startup drop framesNaushir Patuck
Add a new pipeline config parameter "disable_startup_frame_drops" to disable any startup drop frames, overriding the IPA request. When this parameter is set, it allows the pipeline handler to run with no internally allocated Unicam buffers ("min_unicam_buffers").

Add the ability to read the platform configuration parameters from a config file provided by the user through the LIBCAMERA_RPI_CONFIG_FILE environment variable. Use the PipelineHandler::configurationFile() helper to determine the full path of the file. Provide an example configuration file named example.yaml. Currently two parameters are available through the json file: "min_unicam_buffers" The minimum number of internal Unicam buffers to allocate. "min_total_unicam_buffers" The minimum number of internal + external Unicam buffers that must be allocated.

We implement a custom validateColorSpaces method that forces all (non-raw) streams to same colour space, whilst distinguishing RGB streams from YUV ones, as the former must have the YCbCr encoding and range over-written. When we apply the colour space, we always send the full YUV version as that gets converted correctly to what our hardware drivers expect. It is also careful to check what comes back as the YCbCr information gets overwritten again on the way back.

2023-01-30meson: Rework automatic pipeline selectionKieran Bingham
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.

Previously the x,y offsets in the min/max ScalerCrop control values were zero. Here we make them the same as the sensor's analogue crop offset which is I think less misleading. With this change, it also seems reasonable to advertise the default scaler crop value to be the true default that you will get. This makes it possible for applications to see what that value will be without having to start the camera and wait for frames.

As part of that process, it checks that the ipaModuleInfo symbol size matches the expected structure size. This check breaks with clang and ASan, as the LLVM's address sanitizer implementation includes the redzone after the structure in the symbol size, currently growing it by 156 bytes (on x86-64).

2023-01-10libcamera: base: utils: Support C libraries lacking locale supportLaurent Pinchart
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.

The strtod() function is locale-dependent, and thus ill-suited to parse numbers coming from, for instance, YAML files. The YamlObject class uses strtod_l() to fix that issue, but that function is not available with all libc implementations. Correctly handling this problem is becoming out of scope for the YamlObject class. As a first step, add a strtod() helper function in the utils namespace that copies the implementation from YamlObject, and use it in YamlObject. The core issue will then be fixed in utils::strtod().

2023-01-03libcamera: yaml_parser: Use C localeKieran Bingham
When parsing configuration files on systems with differing locales, the use of strtod can produce different results, or in the worst case - fail to parse expected values. Fix this by using strtod_l() instead. To avoid constructing and destructing a locale_t instance for every use of strtod_l(), create an RAII class that wraps the locale_t and use it to provide a global "C" locale.

2022-12-24meson: Only build pipeline handlers needed in the host architectureJavier Martinez Canillas
By default all pipeline handlers are built, regardless on whether these are needed in the host architecture or not. It makes more sense to build only the pipeline handlers that will be used for the given architecture. Let's do that by default now, but still allow to build the other pipeline handlers if needed, by using the `pipelines` meson option. For example, on a x86-64 platform: $ meson build ... Configuration Enabled pipelines : ipu3 uvcvideo Enabled IPA modules : ipu3 ... $ meson build -Dpipelines="ipu3,raspberrypi,rkisp1" -Dtest=true ... Configuration Enabled pipelines : ipu3 raspberrypi rkisp1 vimc Enabled IPA modules : ipu3 raspberrypi rkisp1 vimc ...
