[libcamera-devel] [PATCH 0/8] Add IPAManager and IPAInterface

[Paul Elder]

Pipeline handlers need a way to acquire an IPA module. To achieve this,
we use an IPA manager, that loads many IPA modules, after which a
pipeline handler can ask the IPA manager for an IPA module that matches
it. Each IPA can only be used with one pipeline handler, but a pipeline
handler may work with many IPAs (not simultaneously).
The pipeline handlers also need names and versions (previously only the
factory had a name) to be matched with an IPA module.

Each IPA module, in a shared object, implements an IPAInterface class,
which defines the interface between a pipeline hander and an IPA
implementation, hence the name.

Paul Elder (8):
  libcamera: ipa_interface: add header
  libcamera: pipeline: add name, major version, and minor version
  libcamera: ipa_module_info: update struct to allow IPA matching
  libcamera: ipa_module: allow instantiation of IPAInterface
  libcamera: ipa_manager: implement class for managing IPA modules
  libcamera: ipa: add dummy IPA implementation
  libcamera: test: remove test IPA and use dummy IPA instead
  libcamera: pipeline: vimc: add dummy IPA
