Plumb controls for setting metering mode, exposure mode, constraint mode, and frame duration limits. Also report them as available controls, as well as in metadata. While at it, add the missing #include for tuple, as a std::tie is used.

2024-06-13pipeline: rpi: Don't validate configuration in generateConfiguration()Naushir Patuck
generateConfiguration() called validate() as a final step, causing the stride and frameSize fields in StreamConfiguration to be filled in based on the pixel format and width/height. If a user application did not clear the stride field when setting up a custom pixel format and width/height, the pipeline handler would respect this stride and possibly overallocate buffers with a larger stride than needed. Fix this by removing the call to validate() completely, leaving the stride and frameSize fields defaulting to 0. Removal of this call is inconsequential as we hard-code a valid configuration for Raspberry Pi platforms in generateConfiguration().

2024-06-02libcamera: software_isp: Move color mappings out of debayeringMilan Zamazal
Constructing the color mapping tables is related to stats rather than debayering, where they are applied. Let's move the corresponding code to stats processing. The same applies to the auxiliary gamma table. As the gamma value is currently fixed and used in a single place, with the temporary exception mentioned below, there is no need to share it anywhere anymore. It's necessary to initialize SoftwareIsp::debayerParams_ to default values. These initial values are used for the first two frames, before they are changed based on determined stats. To avoid sharing the gamma value constant in artificial ways, we use 0.5 directly in the initialization. This all is not a particularly elegant thing to do, such a code belongs conceptually to the similar code in stats processing, but doing better is left for larger refactoring. This is a preliminary step towards building this functionality on top of libipa/algorithm.h, which should follow.

2024-05-16ipa: rpi: Add HDR supportNaushir Patuck
Add support for the following HDR modes in the Raspberry Pi IPA: - Night mode - Single exposure mode - Multi-exposure (merged and unmerged) The algorithm is updated to expect the HDR short channel to meter explicitly for highlights. This means that it will not in general under-expose the short channel more than is actually necessary. When images don't have much saturation, it's good to detect this so that some of the boost we want to apply to the dark areas can be implemented as regular gain. This means we can then adjust the tone curve less, leading to less flat looking images. The impact on the HDR algorithm is then that this determines how we build tonemaps dynamically. The highlights are more-or-less correct now, so we have to build a power-type curve that gives us the appropriately configured targets in the lower part of the histogram. We allow the tuning file to supply the maximum spatial gain value, rather than the whole curve (though it can supply this if it wants). Some parameter defaults are tweaked to be generally better across the range of our cameras.

2024-05-14libcamera: camera_manager: Add environment variable to order pipelines matchJulien Vuillaumier
To match the enumerated media devices, each registered pipeline handler is used in no specific order. It is a limitation when several pipelines can match the devices, and user has to select a specific pipeline. For this purpose, environment variable LIBCAMERA_PIPELINES_MATCH_LIST is created to give the option to define an ordered list of pipelines to match on. LIBCAMERA_PIPELINES_MATCH_LIST="<name1>[,<name2>[,<name3>...]]]" Example: LIBCAMERA_PIPELINES_MATCH_LIST="rkisp1,simple" Signed-off-by: Julien Vuillaumier <julien.vuillaumier@nxp.com> Reviewed-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>

2024-05-14libcamera: pipeline: Rename pipelines to a shorter nameJulien Vuillaumier
The PipelineHandlerFactoryBase class has a name that is propagated to the PipelineHandler instance it creates. In present implementation, this name comes from the REGISTER_PIPELINE_HANDLER registration macro. It corresponds to the stringified name of the PipelineHandler derived class. Therefore, PipelineHandler factories and instances names can be quite long such as "PipelineHandlerRkISP1". A libcamera user may have to explicitly refer to a PipelineHandler name for configuration purpose: one usage of the name can be to define a pipeline handlers match list and their priorities. It is desired, for user convenience, to use a short name to designate a pipeline handler. Reusing the short pipeline names already defined in the meson option files is an existing and consistent way of naming pipelines. This change adds an explicit name parameter to the REGISTER_PIPELINE_HANDLER registration macro. That parameter is used to define the name of a pipeline handler factory, instead of the current pipeline handler class name. Each pipeline registration is updated accordingly. The short name assigned corresponds to the pipeline directory name in the source tree. It is consistent with pipelines names used in meson. Changing the pipeline name has an impact on the IPA modules: each module defines a IPAModuleInfo structure. This structure has a pipelineName member defining the pipeline handler name it shall match with. Therefore, each internal IPA module definition has to be changed to have its IPAModuleInfo pipelineName name updated with the short pipeline handler name. In addition to this pipelineName member, the IPAModuleInfo structure also has a name member, associated to the IPA module name. Having renamed the pipelines to a short name, the pipeline name and the IPA module names of the IPAModuleInfo structure are the same: for in-tree IPA, they correspond to the respective pipeline and IPA subdirectories in the source tree. However the IPA name could be different, for instance with a close source IPA implementation built out-of-tree. Thus, it makes sense to keep the IPA name in that structure, as the 2 definitions may not always be redundant.
