2023-03-09libcamera: converter: Check converter validitySuhrid Subramaniam
The ConverterFactoryBase::create() function returns a nullptr when no converter is found. The only caller, SimpleCameraData::init(), checks if the converter is valid with isValid(), but doesn't check if the pointer is null, which can lead to a crash. We could check both pointer validity and converter validity in the caller, but to limit the complexity in callers, it is better to check the converter validity in the create() function and return a null pointer when no valid converter is found.

2023-03-07pipeline: raspberrypi: Iterate over all Unicam instances in match()Naushir Patuck
On Raspberry Pi Compute Module platforms, it is possible to attach a single camera device only to the secondary Unicam port. The current logic of PipelineHandlerRPi::match() will return a failure during enumeration of the first Unicam media device (due to no sensor attached, or sensor failure) and thus the second Unicam media device will never be enumerated. Fix this by looping over all Unicam instances in PipelineHandlerRPi::match() until a camera is correctly registered, or return a failure otherwise.

2023-03-07pipeline: raspberrypi: Add a Unicam timeout override config optionsNaushir Patuck
Add a new parameter to the pipeline handler config file named "unicam_timeout_value_ms" to allow users to override the automatically computed Unicam timeout value. This value is given in milliseconds, and setting a value of 0 (the default value) disables the override. An example use of this parameter would be if an application configured a RAW stream, and provides buffers for the stream on every request. If the application holds off on sending requests for a particular reason (e.g. a timelapse use case), then we will possibly hit the watchdog timeout as it is only a small multiple of the frame length. This override allows an application to select a larger value with the knowledge that it may space requests longer than the calculated timeout value.

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.

2022-12-16libcamera: Add todo comment in meson.build about switch to dependency('dl')Laurent Pinchart
The dlopen() & co. functions are provided by libdl on some systems, and but the C library on others. Starting from version 0.62.0, meson handles this behind the scenes when using dependency('dl'). Add a todo comment to remember we should replace the manual implementation with a dependency() call when updating to meson 0.62.0 or newer.

Move the simple converter implementation to a generic V4L2 M2M class derived from the converter interface. This latter could be used by other pipeline implementations and as base class for customized V4L2 M2M converters.

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.

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.
