Add a sourceStream field to the CameraStream class, meant to contain a reference to the direct stream which produces actual image data for streams of type CameraStream::Mapped. The sourceStream of mapped streams will be used in later patches to make sure for each Mapped stream at least one libcamera::Stream is queued to the libcamera::Camera.

2021-10-26android: post_processor: Make post processing asyncUmang Jain
Introduce a dedicated worker class derived from libcamera::Thread. The worker class maintains a queue for post-processing requests and waits for a post-processing request to become available. It will process them as per FIFO before de-queuing it from the queue. The entire post-processing handling iteration is locked under streamsProcessMutex_ which helps us to queue all the post-processing request at once, before any of the post-processing completion slot (streamProcessingComplete()) is allowed to run for post-processing requests completing in parallel. This helps us to manage both synchronous and asynchronous errors encountered during the entire post processing operation. Since a post-processing operation can even complete after CameraDevice::requestComplete() has returned, we need to check and complete the descriptor from streamProcessingComplete() running in the PostProcessorWorker's thread. This patch also implements a flush() for the PostProcessorWorker class which is responsible to purge post-processing requests queued up while a camera is stopping/flushing. It is hooked with CameraStream::flush(), which isn't used currently but will be used when we handle flush/stop scenarios in greater detail subsequently (in a different patchset). The libcamera request completion handler CameraDevice::requestComplete() assumes that the request that has just completed is at the front of the queue. Now that the post-processor runs asynchronously, this isn't true anymore, a request being post-processed will stay in the queue and a new libcamera request may complete. Remove that assumption, and use the request cookie to obtain the Camera3RequestDescriptor.

2021-10-26android: Track and notify post processing of streamsUmang Jain
Notify that the post processing for a request has been completed, via a signal. The signal is emitted with a context pointer along with status of the buffer. The function CameraDevice::streamProcessingComplete() will finally set the status on the request descriptor and complete the descriptor if all the streams requiring post processing are completed. If buffer status obtained is in error state, notify the status to the framework and set the overall error status on the descriptor via setBufferStatus(). We need to track the number of streams requiring post-processing per Camera3RequestDescriptor (i.e. per capture request). Introduce a std::map to track the post-processing of streams. The nodes are dropped from the map when a particular stream post processing is completed (or on error paths). A std::map is selected for tracking post-processing requests, since we will move post-processing to be asynchronous in subsequent commits. A vector or queue will not be suitable as the sequential order of post-processing completion of various requests won't be guaranteed then. A streamsProcessMutex_ has been introduced here as well, which will be applicable to guard access to descriptor's pendingStreamsToProcess_ when post-processing is moved to be asynchronous in subsequent commits.

2021-10-26android: camera_device: Refactor descriptor status and sendCaptureResults()Umang Jain
Currently, we use Camera3RequestDescriptor::Status to determine: - When the descriptor has been completely processed by HAL - Whether any errors were encountered, during its processing Both of these are essential to know whether the descriptor is eligible to call process_capture_results() through sendCaptureResults(). When a status(Success/Error) is set on the descriptor, it is ready to be sent back via sendCaptureResults(). However, this might lead to undesired results especially when sendCaptureResults() runs in a different thread (for e.g. stream's post-processor async completion slot). This patch decouples the descriptor status (Success/Error) from the descriptor's completion status (pending or complete). The advantage of this is we can set the completion status when the descriptor has been processed fully by the layer and we can set the error status on the descriptor wherever an error is encountered, throughout the lifetime of the descriptor in the HAL layer. While at it, introduce a wrapper completeDescriptor() around sendCaptureResults(). completeDescriptor() as the name suggests will mark the descriptor as complete, so it is ready to be sent back. The locking mechanism is moved from sendCaptureResults() to this wrapper since the intention is to use completeDescriptor() in place of existing sendCaptureResults() calls. Also make sure the sequence of abortRequest() call happens in the same order at all places i.e. after its added to the descriptors_ queue. Fix one of the abortRequest() call accordingly.

2021-10-19android: camera_request: Don't embed full camera3_stream_buffer_tLaurent Pinchart
The camera3_stream_buffer_t structure is meant to communicate between the camera service and the HAL. They are short-live structures that don't outlive the .process_capture_request() operation (when queuing requests) or the .process_capture_result() callback. We currently store copies of the camera3_stream_buffer_t passed to .process_capture_request() in Camera3RequestDescriptor::StreamBuffer to store the structure members that the HAL need, and reuse them when calling the .process_capture_result() callback. This is conceptually not right, as the camera3_stream_buffer_t pass to the callback are not the same objects as the ones received in .process_capture_request(). Store individual fields of the camera3_stream_buffer_t in StreamBuffer instead of copying the whole structure. This gives the HAL full control of how data is stored, and properly decouples request queueing from result reporting.

This complicates buffer handling, as the code needs to keep both vectors in sync. Create a new structure to group all data about per-stream buffers to simplify this. As a side effect, we need to create a local vector of camera3_stream_buffer_t in CameraDevice::sendCaptureResults() as the camera3_stream_buffer_t instances stored in the new structure in Camera3RequestDescriptor are not contiguous anymore.

2021-10-19android: Re-order out-of-order completion pathJacopo Mondi
When the camera HAL detects an out-of-order completion of a request, it sends to the camera framework a CAMERA3_MSG_ERROR_DEVICE error. Such error not only forces the service to close the camera as prescribed by the camera3 specification, but in some implementation (specifically the ChromeOS one) it causes the camera service to abort and exit. This prevents any error messages from being printed by libcamera, as the library gets terminated before getting to that point, and also hides the printout of error messages that lead to out-of-order completion, making it impossible to get from the output log what happened. Move the call to notifyError() at the end of the error path and demote the error message to LogLevels::Error from Fatal to let the service implementation decide how to handle CAMERA3_MSG_ERROR_DEVICE errors. Before this patch, when waiting on a fence fails and the capture request is not queued to the Camera, we get an out-of-order completion but no backtrace. With this patch applied the error path is visible: ERROR HAL camera_worker.cpp:122 Failed waiting for fence: 82: Timer expired ERROR HAL camera_device.cpp:1110 '\_SB_.PCI0.I2C2.CAM0': Out-of-order completion for request 0x00007e6de4004c70 Signed-off-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com>

requests" Commit d165f7da34b8 ("android: camera_device: Configure one stream for identical stream requests") introduced the ability to generate through post-processing YUV streams of identical size and format. However the change didn't fully take into account the situation where only mapped streams are contained in the request submitted by the camera service to the HAL. In this case the Request will be queued with no buffers and refused by the Camera. Even if this seems a corner case it causes a few CTS to fail, and more problematically it triggers out-of-order completion of requests, causing the camera service to abort.

However, when the camera stops, all the current buffers are marked with FrameMetadata::FrameCancelled and proceed to completion. But the buffer associated with the CameraStream (that was previously added to the request) has now been cleared out with a part of streams_.clear(), even before the camera stop() has been invoked.

2021-09-30android: camera_device: Send capture results by inspecting the queueUmang Jain
There is a possibility that an out-of-order completion of capture request happens by calling process_capture_result() directly on error paths. The framework expects that errors should be notified as soon as possible, but the request completion order should remain intact. An existing instance of this is abortRequest(), which sends the capture results on flushing state, without considering order-of-completion. Since we have a queue of Camera3RequestDescriptor tracking each capture request placed by framework to libcamera HAL, we should be only sending back capture results from a single location, by inspecting the queue. As per the patch, this now happens in CameraDevice::sendCaptureResults(). Each descriptor is now equipped with its own status to denote whether the capture request is complete and ready to be send back to the framework or needs to be waited upon. This ensures that the order of completion is respected for the requests. Since we are fixing out-of-order request completion in abortRequest(), change the function to read from the Camera3RequestDescriptor directly, instead of camera3_capture_request_t. The descriptor should have all the information necessary to set the request buffers' state to error.

2021-09-30android: camera_device: Transform descriptors_ map to queueUmang Jain
The descriptors_ map holds Camera3RequestDescriptor(s) which are per-capture requests placed by the framework to libcamera HAL. CameraDevice::requestComplete() looks for the descriptor for which the camera request has been completed and removes it from the map. Since the requests are placed in form of FIFO and the framework expects the order of completion to be FIFO as well, this calls for a need of a queue rather than a std::map. This patch still keeps the same lifetime of Camera3RequestDescriptor as before i.e. in the requestComplete(). Previously, a descriptor was extracted from the map and its lifetime was bound to requestComplete(). The lifetime is kept the same by manually calling .pop_front() on the queue. In the subsequent commit, this is likely to change with a centralized location of dropping descriptors from the queue for request completion.

2021-08-04android: Override camera as "Internal" provided found in HAL configUmang Jain
Currently, all UVC cameras are reported with CameraLocationExternal [1] by libcamera-core since there is no universal information or standard, to know the location of these cameras. However, in the libcamera HAL layer, we can make an informed decision whether it's external or internal, simply by checking its presence in the HAL configuration file. The CameraHalManager will now assign the numerical id of the camera accordingly when initializing the CameraDevice, based on the camera facing value set in the HAL config file.

2021-06-28android: camera_device: Fix null pointer dereferenceLaurent Pinchart
Commit 7532caa2c77b ("android: camera_device: Reset config_ if Camera::configure() fails") reworked the configuration sequence to ensure that the CameraConfiguration pointers gets reset when configuration fails. This inadvertently causes a null pointer dereference, as the CameraStream constructor accesses the camera configuration through CameraDevice::cameraConfiguration() before the internal config_ pointer is set. Fix this by passing the configuration pointer explicitly to the CameraStream constructor.

The config_ pointer is reset in all error paths of the CameraDevice::configureStreams() function, except when Camera::configure() fails. Fix it by using a local unique pointer to store the configuration until the end of the function, to avoid similar issues in the future.

Move the functionality for the following components to the new base support library: - BoundMethod - EventDispatcher - EventDispatcherPoll - Log - Message - Object - Signal - Semaphore - Thread - Timer While it would be preferable to see these split to move one component per commit, these components are all interdependent upon each other, which leaves us with one big change performing the move for all of them.
