[libcamera-devel] [PATCH v3 0/9] IPU3: Introduce modularity for algorithms

[Jean-Michel Hautbois]

This patch series splits the algorithms in IPU3 into a modular form.
When the Metadata class was discussed a proposal from Kieran was to have
a fully-defined structure which would be used to pass the context
between algorithms and the IPAIPU3 class, as well as between the
algorithms themselves.

The algorithms are statically emplaced in a list for the moment, and a
registration system may be used later.
In order to demonstrate how to add a new algorithm, patch 5/9
moves the contrast algorithm from AWB into its own algorithm.

Patch 6/9 and 7/9 change the AWB and AGC to use the new interface.
And the two latest patches are indeed the usage of the new modular
interface applied to AWB and AGC.
