The best example for 3A in libcamera is the Raspberry Pi IPA code.

Please examine:
 src/ipa/raspberrypi/

The Raspberry Pi pipeline handler controls that IPA, so for direction
there, look at :

 src/libcamera/pipeline/raspberrypi/raspberrypi.cpp

But perhaps you are looking for what controls are available for
applications to 'control' the 3A. A lot of that is still under
development, but you should also look at :

 src/libcamera/control_ids.yaml

Which generates docuemntation at :

https://www.libcamera.org/api-html/namespacelibcamera_1_1controls.html


I see from your threads, you have been doing quite a bit of
investigation over the various areas of libcamera.

Perhaps could you share what you are working on with libcamera?

Are you planning to create an application using it? or do you have
devices in mind which you think libcamera should be supporting?
