2020-04-28ipa: Name IPA modules after their source directoryLaurent Pinchart
The IPAModuleInfo::name field is currently a free-formed string that has little use. Tighten its usage rules to make it suitable for building file system paths to IPA-specific resources by matching the directory name of the IPA module.

2020-04-14libcamera: ipa: Remove IPAModuleInfo license fieldLaurent Pinchart
The IPAModuleInfo license field isn't needed anymore now that modules are cryptographically signed. Remove it. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
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.

2020-03-26test: ipa: Fix path to VIMC IPANiklas Söderlund
When changing the VIMC IPA source file structure the path in the ipa_module_test which needs access to the .so file was not updated, fix that. The omission was hard to spot as it requires a clean build of the project as the old .so file is still in the build tree and the test passes.

2020-01-12ipa: Switch to FrameBuffer interfaceNiklas Söderlund
Switch the IPA interfaces and implementations to use the Framebuffer interface. - The IPA interface is switched to use the simpler FrameBuffer::Plane container when carrying dmabuf descriptions (fd and length) over the pipeline/IPA boundary. - The RkISP1 IPA implementation takes advantage of the new simpler and safer (better control over file descriptors) FrameBuffer interface.

2019-10-08test: ipa: Add test for the IPA InterfaceJacopo Mondi
Implement a basic test for IPA Interface using the VIMC dummy IPA module. The test implements an out-of-band feedback channel between the test and the dummy IPA module to verify the success of the IPA interactions. Test the only available operation defined by the IPA interface by receiving a confirmation code on the fifo communication channel.

2019-07-12libcamera: ipa_module_info: add license fieldPaul Elder
Add a field to IPAModuleInfo to contain the license of the module. This license field will be used to determine whether the IPA module should be run in an isolated process or not. If the license is open source, then the IPA module will be allowed to run without process isolation, if the user enables it. If the license is not open source, then the IPA module will be run with process isolation. Update the dummy IPA and IPA test to conform to the new struct layout.

2019-06-05libcamera: ipa_module_info: update struct to allow IPA matchingPaul Elder
We need a way to match pipelines with IPA modules, so add fields in IPAModuleInfo to hold the IPA module API version number, the pipeline name, and the pipeline version. The module API version is used to determine the layout of struct IPAModuleInfo. Also update IPA module tests and Doxygen accordingly. Doxygen needs to be updated to accomodate __attribute__((packed)). Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2019-06-05libcamera: ipa_interface: add headerPaul Elder
Define an IPAInterface class which will contain an IPA implementation. The methods that the IPAInterface exposes form the interface to the IPA implementation, hence the name. IPA module shared objects will implement this class. This also means that IPA module shared objects must be implemented in C++, so remove the C test IPA module.
