2021-05-24ipa: ipu3: Introduce IPAConfigInfo in IPCUmang Jain
IPAConfigInfo is a consolidated data structure passed from IPU3 pipeline-handler to IPU3 IPA. The structure can be extended with additional parameters to accommodate the requirements of multiple IPU3 IPA modules. Adapt the in-tree IPU3 IPA to use IPAConfigInfo as well.

2021-05-24ipa: mojom: Move CameraSensorInfo struct exclusively to IPA IPCUmang Jain
CameraSensorInfo structure is designed to pass in camera sensor related information from pipeline-handler to IPA. Since the pipeline-handler and IPA are connected via mojom IPC IPA interface, the interface itself provides a more suitable placement of CameraSensorInfo, instead of camera_sensor.h (which is a libcamera internal header ultimately, at this point). As CameraSensorInfo is already defined in core.mojom, it is just a matter of removing [skipHeader] tag to allow code-generation of CameraSensorInfo. Finally, update header paths to include CameraSensorInfo definition from IPA interfaces instead of "libcamera/internal/camera_sensor.h".

2021-05-24ipa: Move core IPA interface documentation to a .cpp fileUmang Jain
Moving the core.mojom documentation to its corresponding .cpp file (core_ipa_interface.cpp). This will allow Doxygen to generate the documentation for IPABuffer, IPASettings and IPAStream structures. Since the .mojom files are placed in include/ directory, the .cpp file will live in $sourcedir/src/libcamera/ipa/ - which can also contain documentation for other mojom generated IPA interfaces in subsequent commit. Also hide the constructors in generated IPA interface from doxygen, via #ifndef __DOXYGEN__. These constructors provide no major value in documenting them, instead will spew out doxygen warnings during the build.

2021-05-20libcamera: ipu3: imgu: Fix BDS height calculationJacopo Mondi
The IF rectangle height is iteratively computed by first subtracting the scaling factor to the estimated height, then in a successive loop by adding the same scaling factor until the maximum IF size is not reached. As the computed IF height is not cached in any variable, the second loop over-writes the result of the first one, even if the BDS alignment condition is not satisfied.

2021-05-18android: camera_metadata: Add type sanity check to updateEntry()Laurent Pinchart
The CameraMetadata::updateEntry() functions cast the data pointer to a void pointer, which is then used internally to call update_camera_metadata_entry(). If the caller passes a pointer to an incorrect data type, the behaviour is undefined, with possible crashes if the incorrect data type is smaller than expected by the Android metadata library. To avoid crashes, make all public updateEntry() functions take typed pointers, and pass the element size to the internal function. The element size is then checked against the expected size, and an error message logged if they don't match. This won't catch incorrect data types that have the same size as the correct type, but will at least avoid potential crashes.

Range-based for loops are handy and widely preferred in C++, but are limited in their ability to replace for loops that require access to a loop counter. The enumerate() function solves this problem by wrapping the iterable in an adapter that, when used as a range-expression, will provide iterators whose value_type is a pair of index and value reference. The iterable must support std::begin() and std::end(). This includes all containers provided by the standard C++ library, as well as C-style arrays. A typical usage pattern would use structured binding to store the index and value in two separate variables: std::vector<int> values = ...; for (auto [index, value] : utils::enumerate(values)) { ... } Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>

2021-05-11libcamera: camera_sensor: Fix frame lengths calculated by sensorInfo()David Plowman
The minimum and maximum vblanking can change when a new format is applied to the sensor subdevice, so be sure to retrieve up-to-date values. The V4L2Device acquires the new updateControlInfo() method to perform this function, and which the CameraSensor calls automatically if its setFormat method is used to update the sensor. However, not all pipeline handlers invoke the setFormat method directly, so the new method must be made publicly available for pipeline handlers to call if they need to.

Register static properties in the CameraSensor class by inspecting the camera sensor properties database. Static properties are overridden by properties retrieved from the kernel interface at run-time if any overlap between the two sets occurs.

Introduce a database of camera sensor properties, which contains information on the camera sensor which are not possible, or desirable, to retrieve from the device at run time. The camera sensor database is accessed through a static function and is indexed using the camera sensor model as reported by properties::Model.
