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.

When enumerating IPAs, the system IPA directory and all the directories listed in the LIBCAMERA_IPA_MODULE_PATH environment variable are listed in turn. Failing to list any of those directories results in an error message being printed for every failure.

To avoid unnecessarily worrying error messages, rework the enumeration procedure to only print a message when no IPA can be found at all. Individual missing directories are not considered as an issue anymore. The message is also downgraded from an error to a warning as the situation may still be normal.

2019-09-08libcamera: device_enumerator: fix udev media graph loading dependencyPaul Elder
When a MediaDevice is enumerated and populated by the DeviceEnumeratorUdev, there is a possibility that the member device nodes of the media graph would not be ready (either not created, or without proper permissions set by udev yet). The MediaDevice is still passed up to the pipeline handler, where an attempt to access the device nodes will fail in EPERM. This whole issue is especially likely to happen when libcamera is run at system init time. To fix this, we first split DeviceEnumerator::addDevice() into three methods: - createDevice() to simply create the MediaDevice - populateMediaDevice() to populate the MediaDevice - addDevice() to pass the MediaDevice up to the pipeline handler DeviceEnumeratorSysfs calls these methods in succession, similar to what it did before when they were all together as addDevice(). DeviceEnumeratorUdev additionally keeps a map of MediaDevices to a list of pending device nodes (plus some other auxillary maps), and a simple list of orphan device nodes. If a v4l device node is ready and there does not exist any MediaDevice node for it, then it goes to the orphan list, otherwise it is initialized and removed from the pending list of the corresponding MediaDevice in the dependency map. When a MediaDevice is populated via DeviceEnumeratorUdev::populateMediaDevice(), it first checks the orphan list to see if the device nodes it needs are there, otherwise it tries to initialize the device nodes and if it fails, then it adds the device nodes it wants to its list in the dependency map. This allows MediaDevice instances to be created and initialized properly with udev when v4l device nodes in the media graph may not be ready when the MediaDevice is populated.
