2019-10-13libcamera: control_ids: Generate map of all supported controlsLaurent Pinchart
In order to deserialise a ControlList, we will need to lookup ControlId instances based on their numerical ID. Generate a global map from the controls definitions to support such a lookup.

2019-10-13libcamera: control_ids: Fix documentation for controls namespaceLaurent Pinchart
The controls namespace isn't documenting, making it impossible to reference the variables it contains. Furthermore, within the documentation page for the control_ids.h file, links from overview to detailed variable documentation are broken for the same reason. Both issues can be fixed by documenting the controls namespace. Unfortunately doxygen then fails to parse the initialisers for the controls global variables correctly and considers them as functions. To work around this, modify the control_ids.cpp generation script to hide the variables from doxygen, but still expose their documentation.

With gcc 5 and 6, insertion in a std::multimap copies the pair passed as an argument to the insert() method. As the mapped type is a non-copyable std::unique_ptr<>, this fails to compile. Compilation with newer gcc versions succeed due to support for C++-17 and the fix described in https://cplusplus.github.io/LWG/issue2354.

Add the plumbing to the pipeline handler to interact with an IPA module. This change makes the usage of an IPA module mandatory for the rkisp1 pipeline.

2019-10-05libcamera: controls: Auto-generate control_ids.h and control_ids.cppLaurent Pinchart
Bring back auto-generation of control ids. In this version, both the header and the source files are generated from a single YAML file that stores all control definitions. This allows centralising controls in a single file, while the previous version required keeping both declarations (in a header) and documentation (in a the source) in sync manually. Using YAML as a format to store control definitions is a trade-off between ease of use (there are many YAML parsers available) and simplicity (XML was considered, but would have lead to more complex processing). A new build time dependency is added on python3-yaml, which should be available as a package in all distributions and build environments. The YAML format is likely to change over time as we improve documentation of controls, the first version simply copies the information currently available. Future improvements should also include a YAML schema to validate the YAML source file.

2019-10-04libcamera: controls: Improve the API towards applicationsLaurent Pinchart
Rework the control-related classes to improve the API towards applications. The goal is to enable writing code similar to Request *req = ...; ControlList &controls = req->controls(); controls->set(controls::AwbEnable, false); controls->set(controls::ManualExposure, 1000); ... int32_t exposure = controls->get(controls::ManualExposure); with the get and set operations ensuring type safety for the control values. This is achieved by creating the following classes: - Control defines controls and is the main way to reference a control. It is a template class to allow methods using it to refer to the control type. - ControlId is the base class of Control. It stores the control ID, name and type, and can be used in contexts where a control needs to be referenced regardless of its type (for instance in lists of controls). This class replaces ControlIdentifier. - ControlValue is kept as-is. The ControlList class now exposes two template get() and set() methods that replace the operator[]. They ensure type safety by infering the value type from the Control reference that they receive. The main way to refer to a control is now through the Control class, and optionally through its base ControlId class. The ControlId enumeration is removed, replaced by a list of global Control instances. Numerical control IDs are turned into macros, and are still exposed as they are required to communicate with IPAs (especially to deserialise control lists). They should however not be used by applications. Auto-generation of header and source files is removed for now to keep the change simple. It will be added back in the future in a more elaborate form.
