2021-03-16pipeline: simple: Use breadth-first search to setup media pipelineMarian Cichy
When the SimplePipeline is setting up its data and media pipeline in the SimpleCameraData constructor, it merely tries to find the first valid pad and link to the next entity, starting from the camera sensor. Following this path may not always lead to a valid capture device and therefore the setup will fail on some machines. This is for example an issue when using the SimplePipeline on an i.MX-6Q with its i.MX IPU. This commit implements a different approach to setup the media-pipeline by finding the shortest path to a valid capture device, using the breadth-first search algorithm. On i.MX6Q, the shortest path has a good chance to be the path from the sensor to the CSI capture device, as other paths may involve image converters, encoders or other IPU blocks and will have therefore more nodes.

2021-03-12libcamera: gst: Fix double-free when acquire_buffer failsMarian Cichy
If gst_buffer_pool_acquire_buffer in gst_libcamera_task_run fails, the unique_ptr to the request-object gets reset and hence, its destructor is called. However, the wrap-object points to the same object and is still alive at this moment. When the task_run-function is finished, the destructor of the wrap-object is called, which in return calls the destructor of the request-object again. Instead of taking care of both, the request and the wrap-object, we can move the request to the wrap which will then effectively take care of the request object automatically.

2021-03-12test: delayed_controls: Fixup tests after recent DelayedControls changesNaushir Patuck
The recent fixes applied to DelayedControls change the behavior of the library. As such, the tests ended up failing as they relied on the old behavior of the helper. Update the tests to account for the new behavior and get the tests passing again. Specifically, the following changes have been made for each test: singleControlNoDelay(): - Add a call to reset() to initialise internal DelayedControls state only after setting the control on the device. - Trigger a first frame start by calling applyControls() as a pipeline handler would. - Test frames from 1 onwards, as we will never have a queue item at frame 0, since the reset() handles that. singleControlWithDelay(): - Trigger a first frame start by calling applyControls() as a pipeline handler would. - Test frames from 1 onwards, as we will never have a queue item at frame 0, since the reset() handles that. dualControlsWithDelay() and dualControlsMultiQueue(): - Trigger a first frame start by calling applyControls() as a pipeline handler would. - Test frames from (startOffset + 1) onwards, as we will never have a queue item at frame startOffset. - Use the max delay (2 in this case) to determine the expected result value.

2021-03-12libcamera: delayed_controls: Remove spurious no-op queued controlsNaushir Patuck
In DelayedControls::applyControls(), the controls queue would be extended via a no-op control push to fill the intermittent slots with unchanged control values. This is needed so that we read back unchanged control values correctly on every frame. However, there was one additional no-op performed on every frame that is not required, meaning that any controls queued by the pipeline handler would have their write delayed by one further frame. The original StaggeredCtrl did not do this, as it only had one index to manage, whereas DelayedControls uses two. Remove this last no-op push so that the pipeline_handler provided controls would be written on the very next frame if possible. As a consequence, we must mark the control update as completed within the DelayedControls::applyControls() loop, otherwise it might get reused when cycling through the ring buffer.

2021-03-12libcamera: delayed_controls: Remove unneeded write when starting upNaushir Patuck
On DelayedControls::reset(), the values retrieved from the sensor device were added to the queues with the updated flag set to true. This would cause the helper to write out the value to the device again on the first DelayedControls::applyControls() call. This is unnecessary, as the controls written are identical to what is stored in the device driver. Fix this by explicitly setting the update flag to false in DelayedControls::reset() when adding the controls to the queue. Additionally, use the Info() constructor when adding items to the queue for consistency.

2021-03-12libcamera: delayed_controls: Add notion of priority writeNaushir Patuck
If an exposure time change adjusts the vblanking limits, and we set both VBLANK and EXPOSURE controls through the VIDIOC_S_EXT_CTRLS ioctl, the latter may fail if the value is outside of the limits calculated by the old VBLANK value. This is a limitation in V4L2 and cannot be fixed by setting VBLANK before EXPOSURE in a single VIDIOC_S_EXT_CTRLS ioctl. The workaround here is to have the DelayedControls object mark the VBLANK control as "priority write", which then write VBLANK separately from (and ahead of) any other controls. This way, the sensor driver will update the EXPOSURE control with new limits before the new values is presented, and will thus be seen as valid. To support this, a new struct DelayedControls::ControlParams is used in the constructor to provide the control delay value as well as the priority write flag.

Since commit 96aecfe36508 ("libcamera: camera_sensor: Use active area size as resolution") the CameraSensor::resolution() method returned the sensor's active pixel area size. As the CameraSensor::resolution() method is widely used in the library code base to retrieve the maximum frame size the sensor can produce, in case it is smaller than the pixel area size the returned size cannot be used to configure the sensor correctly. Fix this by returning the maximum frame resolution the sensor can produce, or the pixel area size in case the sensor embeds and ISP that can upscale and the supported maximum frame size is thus larger that the pixel array size.

2021-03-08tracing: pipeline_handler: Queue RequestsKieran Bingham
Add tracing to the base pipeline handler class to track when requests are queued. Tracing is already available for other Request operations, but queuing a Request is not an operation handled by the Request itself. Add the tracepoint to the PipelineHandler::queueRequest() so the lifetime of a Request can be viewed when tracing.

The packages required for tracing libcamera projects were incorrectly specified. Update with the correct prefix for the dev package on liblttng-ust-dev and also provide the lttng-tools package which provides the utilities required to handle tracing.

2021-03-08libcamera: pipeline_handler: Update request usage commentKieran Bingham
When a pipeline handler completes a request, the request itself is not deleted by libcamera, and the application regains control over the object. It may choose to delete the Request, or re-use it. Clarify this in the comment by removing the declaration that the Request is deleted, but state that it is no longer managed by the pipeline handler and must not be accessed further after this function returns.

2021-03-08libcamera: Request: validate state on completeKieran Bingham
Requests should only be completed from the RequestPending state. Requests which are completed from the RequestCancelled, or RequestComplete state, will indicate that a double-complete has been called on the Request, or that it has been used internally after it has been given back to the application. Ensure that this can be caught early if it occurs by enforcing the state required with an assert.
