2019-11-20test: ipa: Add IPA wrappers testLaurent Pinchart
Wrap an IPAInterface in an IPAInterfaceWrapper in an IPAContextWrapper, and verify that the translation between C and C++ APIs work correctly. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
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: Declare the ipaCreate() function prototypeLaurent Pinchart
IPA modules have to implement a public ipaCreate() function, but its prototype isn't declared in any header file. This allows for modules to get the prototype wrong without being warned by the compiler. Fix it.

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.

2019-11-20ipa: Define a plain C APILaurent Pinchart
The C++ objects that are expected to convey data through the IPA API will have associated methods that would require IPAs to link to libcamera. Even though the libcamera license allows this, suppliers of closed-source IPAs may have a different interpretation. To ease their mind and clearly separate vendor code and libcamera code, define a plain C IPA API. The corresponding C objects are stored in plain C structures or have their binary format documented, removing the need for linking to libcamera code on the IPA side. The C API adds three new C structures, ipa_context, ipa_context_ops and ipa_callback_ops. The ipa_context_ops and ipa_callback_ops contain function pointers for all the IPA interface methods and signals, respectively. The ipa_context represents a context of operation for the IPA, and is passed to the IPA oparations. The IPAInterface class is retained as it is easier to use than a plain C API for pipeline handlers, and wrappers will be developed to translate between the C and C++ APIs. Switching to the C API internally will be done in a second step.
