2022-11-24libcamera: tracing: fix header generation when built as subprojectBarnabás Pőcze
Building libcamera as a subproject is failing when tracepoints are enabled due to incorrectly managing the relative paths between the source and build directory while generating tracepoint headers. The previously used path = output.replace('include/', '', 1) logic is not sufficient to correctly determine the proper path when libcamera is built as a subproject, and does not correctly handle the relative paths, causing path to be processed as: 'subprojects/libcamera/include/libcamera/internal/tracepoints.h'.replace('include/', '', 1) which evaluates to 'subprojects/libcamera/libcamera/internal/tracepoints.h' so the tracepoints.h header file will try to include: #define TRACEPOINT_INCLUDE "subprojects/libcamera/libcamera/internal/tracepoints.h" which will fail. Fix it by using Python's pathlib to calculate the relative path of the output file with respect to the "include" directory of libcamera. This has been tested with Pipewire. For non-subproject builds it should generate the exact same path that was previously generated.

2022-10-18utils: ipc: Allow the skipHeader attribute on enumsPaul Elder
Currently, enums that are passed between pipeline handlers and their IPA must be defined in a mojom file. However, there is a use case for enum/flags to be defined in a C++ header, such that the enum can be used in a component other than the pipeline handler and its IPA. To support this, add support for the skipHeader attribute for enums. Like structs, it is only allowed in core.mojom.

2022-10-18utils: ipc: Add support for FlagsPaul Elder
Add Flags<E> as a supported type in the IPA interface. It is used in mojom with the [flags] attribute. Any field or parameter type E that is prefixed with the [flags] attribute will direct the code generator to generate the type name "Flags<E>" and appropriate serialization/deserialization code for Flags<E> instead of for E. It is usable and has been tested in struct members, function input and output parameters, and Signal parameters. This does not add support for returning Flags as direct return values. Additionally, the [scopedEnum] attribute can be used on enum definitions, which will instruct the code generator to convert it to an enum class instead of a raw enum.

2022-10-07utils: gen-controls: Improve YAML notation for variable-size array controlsLaurent Pinchart
Array controls specify the array size through the YAML 'size' element, which stores a list of values, one per dimension. Variable-size arrays currently use an empty 'size' list, which prevents describing the number of dimensions of the array. Improve this by using the same notation for fixed-size and variable-size array controls. Dimensions that are not fixed are described as a string instead of an integer, such as [n], [n,3] or [w,h]. The strings have currently no special meaning, this may change in the future. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com>

2022-08-03utils: raspberrypi: ctt: dng_load_image: Work with DNG files from Picamera2William Vinnicombe
The DNG specification is based on the TIFF file format and recommends storing the raw image data in a SubIFD and the Exif tags in an Exif IFD. Other options are allowed, even if not recommended, such as storing both the raw image data and the Exif data in IFD0, as done by the TIFF/EP specification. libcamera-apps use pyexiv2 to produce DNG files, following the DNG recommendation, while applications based on picamera2 use PiDNG, which adopts the TIFF/EP structure. Why it does so is not currently clear (see https://github.com/schoolpost/PiDNG/issues/65 for discussions on this topic), but as files based on the DNG and TIFF/EP variants exist in the wild, both need to be supported by ctt.
