The configuration snippet: configuration: ipa: config_paths: - config path 1 - config path 2 - ... module_paths: - module path 1 - module path 2 - ... proxy_paths: - proxy path 1 - proxy path 2 - ... force_isolation: BOOL LIBCAMERA__TUNING_FILE remains configurable only via the environment variable; this is supposed to be used only for testing and debugging and it's not clear what to do about IPA names like "rpi/vc4" and "rpi/pisp" exactly. There are two ways to pass the configuration to the places where it is needed: Either to pass it as an argument to the method calls that need it, or to pass it to the class constructors and extract the needed configuration from there. This patch uses the second method as it is less polluting the code.
