2020-04-28libcamera: ipa: Add support for CameraSensorInfoJacopo Mondi
Add support for camera sensor information in the libcamera IPA protocol. Define a new 'struct ipa_sensor_info' structure in the IPA context and use it to perform translation between the C and the C++ API. Update the IPAInterface::configure() operation to accept a new CameraSensorInfo parameter and port all users of that function to the new interface. Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>
2020-04-28ipa: vimc: Validate configuration file in init()Laurent Pinchart
Make sure we can open the configuration file passed to the init() function, and return an error otherwise. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2020-04-28ipa: vimc: Add a dummy configuration file to the vimc IPALaurent Pinchart
The file will be used to test the corresponding APIs. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
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.

2020-04-28ipa: 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.

2020-04-16libcamera: Make IPA module signing optionalLaurent Pinchart
The IPA module signing mechanism relies on openssl to generate keys and sign the module. If openssl is not found on the system, the build will fail. Make the dependency optional by detecting openssl, and skip generation of signatures if openssl isn't found.

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>
2020-04-14libcamera: Add IPA module signing infrastructureLaurent Pinchart
Add infrastructure to generate an RSA private key and sign IPA modules. The signatures are stored in separate files with a .sign suffix. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2020-04-14ipa: vimc: Remove isolated VIMC IPA moduleLaurent Pinchart
The isolated VIMC module isn't used in any test. Remove it to prepare for the rework of IPA module isolation. The feature can be added back later alongside corresponding tests if needed.

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.

2020-03-25ipa: Move vimc to a subdirectoryLaurent Pinchart
Give a subdirectory to all IPA modules to make the structure of the source tree more consistent. This will also simplify the implementation of IPA module selection at build time.
