2019-01-24libcamera: device_enumerator: Reference-count MediaDevice instancesLaurent Pinchart
The MediaDevice class will be the entry point to hot-unplug, as it corresponds to the kernel devices that will report device removal events. The class will signal media device disconnection to pipeline handlers, which will clean up resources as a result. This can't be performed synchronously as references may exist to the related Camera objects in applications. The MediaDevice object thus needs to be reference-counted in order to support unplugging, as otherwise pipeline handlers would be required to drop all the references to the media device they have borrowed synchronously with the disconnection signal handler, which would be very error prone (if even possible at all in a sane way). Handle MedieDevice instances with std::shared_ptr<> to support this. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>

2019-01-22test: pipeline: IPU3: Add IPU3 pipeline testJacopo Mondi
Add test for the Intel IPU3 pipeline that lists all the cameras registered in the system and verifies the result matches the expected. This test is meant to be run on IPU3 platforms, it gets skipped otherwise.
