2023-01-31pipeline: raspberrypi: Reorder startup drop frame initialisationNaushir Patuck
Reorder the code such that the IPA requested startup drop frames count is available before the pipeline handler allocates any stream buffers. This will be used in a subsequent change to stop Unicam buffer allocations if there are no startup drop frames required and the application has configured a raw stream and always provides buffers for it.

2023-01-31pipeline: raspberrypi: Add a pipeline config structureNaushir Patuck
Add a configuration structure to store platform specific parameters used by the pipeline handler. Currently, these only store Unicam buffer counts, replacing the hardcoded static values in the source code. In subsequent commits, more parameters will be added to the configuration structure, and parameters will be read in through a config file.

Add a new helper function PipelineHandler::configurationFile() that returns the full path of a named configuration file. This configuration file may be read by pipeline handlers for platform specific configuration parameters on initialisation. The mechanism for searching for the configuration file is similar to the IPA configuration file: - In the source tree if libcamera is not installed - Otherwise in standard system locations (etc and share directories). When stored in the source tree, configuration files shall be located in a 'data' subdirectory of their respective pipeline handler directory.

2023-01-31pipeline: raspberrypi: Fix handling of colour spacesDavid Plowman
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.

When an IPA module is loaded, the loadIPAModuleInfo() function validates the ipaModuleInfo structure. 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). This causes all IPA modules to fail to load. Fix the problem by relaxing the size check to only ensure that the symbol is large enough to contain the structure.

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.

2022-12-14libcamera: Declare generic converter interfaceXavier Roumegue
Declare a converter Abstract Base Class intended to provide generic interfaces to hardware offering size and format conversion services on streams. This is mainly based on the public interfaces of the current converter class implementation found in the simple pipeline handler. The main change is the introduction of loadConfiguration() function which can be used by the concrete implementation to load hardware specific runtime parameters defined by the application.

2022-12-12libcamera: camera_sensor: Rectify test patterns listed for IMX519Umang Jain
The IMX519 driver reports ColorBars and ColorBarsFadeToGray but upon inspecting the test pattern modes via v4l2-ctl utility, these test patterns do not comply with MIPI CCS v1.1 (Section 10.1). Hence, omit from camera-sensor-properties database for now and add a comment for the same.
