2019-08-13libcamera: v4l2_videodevice: Fix ordering of debug statementKieran Bingham
The "Opened device" statement occurs before the buffertype_ is set. This causes all devices to report that they are [out] devices at open() regardless of their type. As the message operates in the past-tense, move the statement to the end of the function when all work has been completed.

The CameraHalManager::getCameraInfo() validates the camera id it receives from the camera service, and in doing so compares it with an unsigned integer, generating a compiler error: src/android/camera_hal_manager.cpp:121:9: error: comparison of integers of different signs: 'int' and 'unsigned int' [-Werror,-Wsign-compare] if (id >= numCameras() || id < 0) { ~~ ^ ~~~~~~~~~~~~ Fix this by turning the id into an unsigned int, as camera ids can't be negative.

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.

The IPAModule::loadIPAModuleInfo() function includes a *data pointer which is used as a null-pointer comparison in the error path with a conditional statement of "if (ret || !data)". The data variable is not initialised, and a single error path evaluates this as "if (true || uninitialised)".

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.

2019-07-14libcamera: buffer: Split memory information to BufferMemoryLaurent Pinchart
The Buffer class is a large beast the stores information about the buffer memory, dynamic metadata related to the frame stored in the buffer, and buffer reference data (in the index). In order to implement buffer import we will need to extend this with dmabuf file descriptors, making usage of the class even more complex. Refactor the Buffer class by splitting the buffer memory information to a BufferMemory class, and repurposing the Buffer class to reference a buffer and to store dynamic metadata. The BufferMemory class becomes a long term storage, valid and stable from the time buffer memory is allocated to the time it is freed. The Buffer class, on the other hand, becomes transient, is created on demand when an application requires a buffer, is given to a request, and is deleted when the request completes. Buffer and BufferMemory don't need to be copied, so their copy constructor and assignment operators are deleted.
