[libcamera-devel] [PATCH v4 0/8] libcamera: ipa_manager: Proxy open-source IPAs to a thread

[Niklas Söderlund]

Hello,

This series tries to solve some issues discovered by testing Laurent's
patch (8/8 in this series). The main change is to extend the
IPAInterface with a start() and stop() method that can deal with things
as starting threads or allocating resources needed by the IPA in tandem
with the camera start and stop.

The series is a mix of patches to the rkisp1 pipeline handler solving
issues uncovered by running the IPA in a separate thread, adding the IPA
start() and stop() methods and integrating them with Laurent's work to
run open-source IPAs in a thread.
