2019-10-13libcamera: controls: Default ControlList validator argument to nullptrLaurent Pinchart
The ControlList constructor takes a validator pointer that can be null. Set its default value to nullptr to simplify code in users of ControlList.

2019-10-11libcamera: ipa: rkisp1: Add basic control of auto exposureNiklas Söderlund
Add an IPA which controls the exposure time and analog gain for a sensor connected to the rkisp1 pipeline. The IPA supports turning AE on and off and informing the camera of the status of the AE control loop.

The IPA interface needs to support interactions with the pipeline; add interfaces to control the sensor and handling of request ISP parameters and statistics.

2019-10-08ipa: vimc: Add support for tracing operationsJacopo Mondi
Add support to the dummy VIMC IPA for tracing operation by using a FIFO channel that will be used by the IPA Interface test to verify communications with the IPA. At the moment only add support for the init() operation as it's the only defined one. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>

Open source IPA implementations can benefit from usage of libcamera internal APIs. Allow this by compiling against the internal headers and linking against libcamera. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>

2019-09-15ipa: Generate the two dummy IPA modules from the same sourceLaurent Pinchart
The ipa_dummy.cpp and ipa_dummy_isolate.cpp only differ in the license reported in the IPAModuleInfo structure. Drop the second file and generate the two .so from ipa_dummy.cpp, with the license defined through the command line.

2019-09-15libcamera: Move ipa includes to the same level as libcameraLaurent Pinchart
The ipa includes are located in include/libcamera/ipa/. This gives an incorrect impression that they are a sub-part of the rest of the libcamera API, while they are the API towards the IPA the same way that include/libcamera/ contains the API towards applications. To clarify this, move them to include/ipa/. The IPA headers are however still part of libcamera, so installing them to ${prefix}/include/ipa/ would make little sense. To fix this, move the application facing API to ${prefix}/include/libcamera/libcamera/ when installed, and the IPA to ${prefix}/include/libcamera/ipa/. When major versions of libcamera will be released, they could then be installed side by side in ${prefix}/include/libcamera-${version}/.

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_manager: implement class for managing IPA modulesPaul Elder
IPAManager is a class that will search in given directories for IPA modules, and will load them into a list. It also provides an interface for pipeline handlers to acquire an IPA. A meson build file for the IPAs is added, which also specifies a hard-coded path for where to load the IPAs from in the installation directory. More paths can be specified with the environment variable LIBCAMERA_IPA_MODULE_PATH, with the same syntax as the regular PATH environment variable. Make the test framework set this environment variable. Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
