2021-06-25android: cros: Simplify integrationKieran Bingham
The ChromeOS specific Android HAL support was overly-complex to support linking an additional library, and then passing the built object into the libcamera.so build. Now that it has its own distinct libcamera-hal.so, simplify the CrOS integration to build directly into that library. The removal of the -Wno-shadow here is intentional, as it is not required for compilation of the camera3_hal.o object.

Commit 922833f774f6 ("libcamera: simple: Report sensor timestamp") unconditionally tries to access the request through the capture buffer to store the capture timestamp in the metadata. This causes a null pointer dereference when using a converter, as the capture buffers are free-wheeling in that case, and not associated with a request. Fix this by getting the request from the user-facing buffer, which can be the capture buffer when no converter is used.

2021-06-15libcamera: log: Destroy LogCategory instances in a controlled wayLaurent Pinchart
The LogCategory instances are constructed on first use as static variables in accessor functions, following the Meyers singleton pattern. As a result, their destruction order is not guaranteed. This can cause issues as the global Logger object, constructed in a similar fashion, is accessed from the LogCategory destructor and may be destroyed first. To fix this, keep the same singleton pattern, but allocate the LogCategory instances dynamically. As they get registered with the global Logger instance, we can destroy them in the Logger destructor. This only avoids destruction order issues between LogCategory and Logger, and doesn't address yet the fact that LOG() calls from destructors of global objects may access an already destroyed Logger.

Implement the flush() camera operation in the CameraDevice class and make it available to the camera framework by implementing the operation wrapper in camera_ops.cpp. Introduce a new camera state State::Flushing to handle concurrent flush() and process_capture_request() calls. As flush() can race with processCaptureRequest() protect it by introducing a new State::Flushing state that processCaptureRequest() inspects before queuing the Request to the Camera. If flush() is in progress while processCaptureRequest() is called, return the current Request immediately in error state. If flush() has completed and a new call to processCaptureRequest() is made just after, start the camera again before queuing the request.

2021-06-14android: Rework request completion notificationJacopo Mondi
The current implementation of CameraDevice::requestComplete() which handles event notification and calls the framework capture result callback does not handle error notification precisely enough. In detail: - Error notification is an asynchronous callback that has to be notified to the framework as soon as an error condition is detected, and it independent from the process_capture_result() callback - Error notification requires the HAL to report the precise error cause, by specifying the correct CAMERA3_MSG_ERROR_* error code. The current implementation only notifies errors of type CAMERA3_MSG_ERROR_REQUEST at the end of the procedure, before the callback invocation. Rework the procedure to: - Notify CAMERA3_MSG_ERROR_DEVICE and perform library tear-down in case a Fatal error is detected - Notify CAMERA3_MSG_ERROR_REQUEST if the libcamera::Request::status is different than RequestCompleted and immediately call process_capture_result() with all buffers in error state. - Notify the shutter event as soon as possible - Notify CAMERA3_MSG_ERROR_RESULT in case the metadata cannot be generated correctly and call process_capture_result() with the right buffer state regardless of metadata availability. - Notify CAMERA3_MSG_ERROR_BUFFER for buffers whose post-processing failed While at it, return the CameraStream buffer by calling cameraStream->putBuffer() regardless of the post-processing result.

Since line duration is now calculated from real values, store it as a private member in IPU3Agc class. As a further step, replace the associated global constant, kMaxExposureTime, with a private IPU3Agc class member as well, and assign its value correspondingly in IPU3Agc::initialise(), similar to previous precedence.

2021-06-07gstreamer: Add error checking in gst_libcamera_src_task_enter()Vedant Paranjape
The return value from generateConfiguration() was not checked. Only assert was added as a guard which checked if the size of the generated camera config was equal to size of roles passed to it. If the roles variable has an invalid/unsupported role, it will return a nullptr and then trying to access a member on a nullptr for size comparison will result in a segmentation fault. So, if the function returns a nullptr, simply push an error message on GstBus and gracefully exit.

2021-06-07libcamera: V4L2Device: Remove the controls order assumption in updateControls()Hirokazu Honda
The original updateControls() has the assumption that ctrls and v4l2Ctrls lists are in the same order. It is dependent on the caller implementation though. This changes updateControls() implementation so that it works without the assumption.

2021-06-04libcamera: Add libcamera_generated_ipa_headers as a dependency for libcamera_depNiklas Söderlund
Some external components such as the unit tests include headers generated for the IPA's. This is not fully described in meson for each external component which results in one or more races in the build system. Instead of playing whack-a-mole add the generated IPA headers to libcamera_dep.
