2021-07-11base: thread: Fix recursive calls to dispatchMessages()Laurent Pinchart
There are use cases for calling the dispatchMessages() function recursively, from within a message handler. This can be used, for instance, to force delivery of messages posted to a thread concurrently to stopping the thread. This currently causes access, in the outer dispatchMessages() call, to iterators that have been invalidated by erasing list elements in the recursive call, leading to undefined behaviour (most likely double-free or other crashes). Fix it by only erasing messages from the list at the end of the outer call, identified using a recursion counter.

2021-06-28ipa: Create a camera sensor helper classJean-Michel Hautbois
For various sensor operations, it may be needed to do sensor specific computations, like analogue gain or vertical blanking. This commit introduces a new camera sensor helper in libipa which aims to solve this specific issue. It is based on the MIPI alliance Specification for Camera Command Set and implements, for now, only the analogue "Global gain" mode. Setting analogue gain for a specific sensor is not a straightforward operation, as one needs to know how the gain is calculated for it. Three helpers are created in this patch: imx219, ov5670 and ov5693. Adding a new sensor is pretty straightforward as one only needs to implement the sub-class for it and register that class to the CameraSensorHelperFactory.

Commit 7532caa2c77b ("android: camera_device: Reset config_ if Camera::configure() fails") reworked the configuration sequence to ensure that the CameraConfiguration pointers gets reset when configuration fails.

A pkg-config file is generated and named libcamera-base.pc which allows components such as external IPA modules to link directly to this library if they need. Normal applications will reference this library through the Requires: statement provided by the libcamera.pc package configuration, and linkage will be handled automatically through the pkg-config mechanisms.

As a result of this, the pkgconfig file is now named 'libcamera.pc' as opposed to 'camera.pc', and applications desiring to reference libcamera will need to search for 'libcamera' as a dependency rather than 'camera'.
