2020-04-28ipa: Pass IPA initialization settings to IPAInterface::init()Laurent Pinchart
Add a new IPASettings class to pass IPA initialization settings through the IPAInterface::init() method. The settings currently only contain the name of a configuration file, and are expected to be extended later.

2020-04-14ipa: Add start() and stop() operationsNiklas Söderlund
Add two new operations to the IPA interface to start and stop it. The intention is that these functions shall be used by the IPA to perform actions when the camera is started and stopped.

2019-11-20ipa: Allow short-circuiting the ipa_context_opsLaurent Pinchart
When an IPA module is loaded without isolation and implements the IPAInterface internally, going through ipa_context_ops is a waste of time. Add an operation to retrieve the IPAInterface, and use it directly in the IPAContextWrapper. For debugging purpose, make it possible to forcing usage of the C API by defining the LIBCAMERA_IPA_FORCE_C_API environment variable.

2019-11-20ipa: Switch to the plain C APIJacopo Mondi
Switch IPA communication to the plain C API. As the IPAInterface class is easier to use for pipeline handlers than a plain C API, retain it and add an IPAContextWrapper that translate between the C++ and the C APIs. On the IPA module side usage of IPAInterface may be desired for IPAs implemented in C++ that want to link to libcamera. For those IPAs, a new IPAInterfaceWrapper helper class is introduced to wrap the IPAInterface implemented internally by the IPA module into an ipa_context, ipa_context_ops and ipa_callback_ops.
