2021-08-09libcamera: Rename 'method' to 'function'Laurent Pinchart
Usage of 'method' to refer to member functions comes from Java. The C++ standard uses the term 'function' only. Replace 'method' with 'function' or 'member function' through the whole code base and documentation. While at it, fix two typos (s/backeng/backend/). The BoundMethod and Object::invokeMethod() are left as-is here, and will be addressed separately.

2021-06-25libcamera/base: Move extended base functionalityKieran Bingham
Move the functionality for the following components to the new base support library: - BoundMethod - EventDispatcher - EventDispatcherPoll - Log - Message - Object - Signal - Semaphore - Thread - Timer While it would be preferable to see these split to move one component per commit, these components are all interdependent upon each other, which leaves us with one big change performing the move for all of them.

2020-12-28libcamera: pipeline_handler: Remove Camera argument from request handlingNiklas Söderlund
There is no need to pass the Camera pointer to queueRequest(), completeBuffer() and completeRequest() as the Request also passed contains the same information. Remove the Camera argument to avoid situations where the information in the Request and the argument differ. There is no functional change and no public API change as the interface is only used between the Camera and PipelineHandler.

2020-12-08libcamera: pipeline: Pass libcamera controls into pipeline_handler::start()Naushir Patuck
Applications now have the ability to pass in controls that need to be applied on startup, rather than doing it through Request where there might be some frames of delay in getting the controls applied. This commit adds the ability to pass in a set of libcamera controls into the pipeline handlers through the pipeline_handler::start() method. These controls are provided by the application through the camera::start() public API.
