2019-08-11libcamera: pipeline: vimc: Switch to using the RGB/YUV Capture video nodeNiklas Söderlund
Linux commit 85ab1aa1fac17bcd ("media: vimc: deb: fix default sink bayer format") which is part of v5.2 changes the default media bus format for the debayer subdevices. This leads to a -EPIPE error when trying to use the raw capture video device nodes. Fix this by moving the vimc pipeline to use the RGB/YUV Capture capture video node. As a consequence of this change the scaler in the vimc pipeline is used and a hard coded upscale of 3 is present in the video pipeline. This limits the sizes exposed and accepted by libcamera to multiples of 3. Update the buffer import test case to match this new format constraint by setting the resolution to 1920x1080, a resolution which works with both vimc and vivid. With this new resolution the buffer import test takes a bit more time to complete 60 buffers and it's runtime also needs to be increased. The raw capture video node still needs to be handled by the pipeline as its format needs to be updated to allow the pipeline format validation to pass.

2019-07-17libcamera: ipu3: Do not re-queue cancelled buffersJacopo Mondi
When a video device is stopped all the buffers there queued are released and their state is set to BufferCancelled. Currently, on buffer completion, cancelled buffers are blindly re-queued to the ImgU input or CIO2 output devices, preventing them to be re-started succesfully in future capture sessions. Fix that by inspecting the buffers status and skip re-queueing if they're reported as cancelled. For the ImgU output buffer this is not required, as cancelled request should be reported to applications in order to report them failure of the capture operations.

2019-07-17libcamera: ipu3: Disable links at configure() timeJacopo Mondi
With the current IPU3 kernel driver implementation, a linked pipe shall be used (buffers should be queued on it) in order not to block all other pipes. Currently all links on the ImgU device are only disabled at match() time, implying that once an ImgU pipe gets linked, it should be used until the whole pipeline is not re-matched and links disabled again. This is a severe limitation for applications that wants to switch between cameras using different pipes going through a full library tear-down and reload. Perform link disabling at configure() time as well, so that a camera configuration operation always unlock the usage of the assigned pipe, regardless of the previously linked ones. Unfortunately this requires a camera start/stop sequence to always go through a configure step, a requirement that is not enforced by the Camera state machine.

2019-07-16libcamera: pipeline: ipu3: Free internal buffers after stopping streamingLaurent Pinchart
The internal buffers between the CIO2 and ImgU are freed by the CIO2Device::stop() method, which is called first when stopping streaming. The ImgUDevice::stop() method is then called, and attempts to report completion for all queued buffers, which we have just freed. The use-after-free corrupts memory, leading to crashes. Fix this by moving the vector of internal buffers to the IPU3CameraData where it belongs, and free the buffers after stopping both devices.

2019-05-23libcamera: camera: Add a validation API to the CameraConfiguration classLaurent Pinchart
The CameraConfiguration class implements a simple storage of StreamConfiguration with internal validation limited to verifying that the stream configurations are not empty. Extend this mechanism by implementing a smart validate() method backed by pipeline handlers. This new mechanism changes the semantic of the camera configuration. The Camera::generateConfiguration() operation still generates a default configuration based on roles, but now also supports generating empty configurations to be filled by applications. Applications can inspect the configuration, optionally modify it, and validate it. The validation implements "try" semantics and adjusts invalid configurations instead of rejecting them completely. Applications then decide whether to accept the modified configuration, or try again with a different set of parameters. Once the configuration is valid, it is passed to Camera::configure(), and pipeline handlers are guaranteed that the configuration they receive is valid. A reference to the Camera may need to be stored in the CameraConfiguration derived classes in order to access it from their validate() implementation. This must be stored as a std::shared_ptr<> as the CameraConfiguration instances belong to applications. In order to make this possible, make the Camera class inherit from std::shared_from_this<>.

Refactor the CameraConfiguration structure to not rely on Stream instances. This is a step towards making the camera configuration object more powerful with configuration validation using "try" semantics. The CameraConfiguration now exposes a simple vector-like API to access the contained stream configurations. Both operator[]() and at() are provided to access elements. The isEmpty() method is renamed to empty() and the methods reordered to match the std::vector class. As applications need access to the Stream instances associated with the configuration entries in order to associate buffers with streams when creating requests, expose the stream selected by the pipeline handler through a new StreamConfiguration::stream().

Instead of requiring each pipeline handle implementation to keep track of calling release() on its media devices upon deletion, keep track of them in the base class. Add a helper that pipeline handlers shall use to acquire a media device instead of directly interacting with the DeviceEnumerator. This also means that pipeline handler implementations do no need to keep a shared_ptr<> reference to the media devices they store locally as the PipelineHandler base class will keep a shared_ptr<> reference to all media devices consumed for the entire lifetime of the pipeline handler implementation.
