2020-08-05libcamera: sysfs: Add helper to lookup device firmware node pathNiklas Söderlund
A system's firmware description is recorded differently in sysfs depending if the system uses DT or ACPI. Add a helper to abstract this, allowing users not to care which of the two are used. For DT-based systems, the path is the full name of the DT node that represents the device. For ACPI-based systems, the path is the absolute namespace path to the ACPI object that represents the device. In both cases, the path is guaranteed to be unique and persistent as long as the system firmware is not modified.

2020-08-05libcamera: ipa: raspberrypi: ALSC: Improve behaviour when camera mode changesDavid Plowman
Now that we stop the asynchronous thread on a SwitchMode, we would do better to regenerate all the tables if the new camera mode crops in a significantly different way to the old one. A few minor tweaks make sense along with this: * Reset the lambda values when we reset everything. It wouldn't make sense to re-start with the old mode's values. * Use the last recorded colour temperature to generate new tables rather than any default value. * Set the frame "phase" counter to ensure the adaptive procedure will run asap.

2020-08-05libcamera: ipa: raspberrypi: ALSC: Resample luminance tableDavid Plowman
This fixes a bug where the luminance correction table was not being resampled according to the camera mode, in the same way as the colour tables. This could be noticeable if any camera modes crop aggressively. This resampling can be done "up front" in the SwitchMode, as we have only a single fixed luminance table. In order to protect the recalculation of the table from the asynchronous thread (which reads it) I've elected to wait for that thread to go idle (though I doubt it would have mattered much). As a by-product of stopping the thread, it no longer needs its own copy of the camera mode (async_camera_mode_).

The stream assignment was based on the order in which elements were inserted in the vector, implementing a fragile association between streams and their intended configurations. As it is now possible to assign streams at validation time, there is no need to keep that association in place, and the streams_ vector is now unused.

Remove the adjustStream() and assignStream() methods, and perform stream adjustment and assignment while iterating the StreamConfiguration items. The adjustStream() implementation had some arbitrary assumption, like the main output having to be as large as the sensor resolution, and did not take into account the different alignment requirements between the main output and the viewfinder output. The assignStream() implementation also assumes only full-size streams can be produced by the main output, and having it as a separate function prevents adjusting streams according to which output they are assigned. Blend the two implementation in a single loop and perform the required stream adjustment and assignment in one go. As streams are now assigned at validate() time, remove the same operation from the configure() function.

2020-07-31libcamera: object: Add deleteLater() supportUmang Jain
This commit adds support to schedule the deletion of an Object to the thread it is bound to (similar to [1]). An Object getting destroyed by a different thread is considered as a violation as per the libcamera threading model. This will be useful for an Object where its ownership is shared via shared pointers in different threads. If the thread which drops the last reference of the Object is a different thread, the destructors get called in that particular thread, not the one Object is bound to. Hence, in order to resolve this kind of situation, the creation of shared pointer can be accompanied by a custom deleter which in turns use deleteLater() to ensure the Object is destroyed in its own thread.
