2021-12-22android: camera_metadata: Add setEntry helperPaul Elder
Add setEntry() helper, that automatically detects if updateEntry() or addEntry() should be used. Note that updateEntry() will fail if the entry was not yet added, and addEntry() will fail is the entry was already added. They are silent failures that cause unexpected values to find their way into the android metadata instance. Previously this helper was not necessary, as (with respect to the current use case) the preview template generator would always add a key so the other template generators that used the preview template as boilerplate could reliably use updateEntry(). The preview template generator will soon decide based on capabilities whether or not to add keys, so the other template generators need a helper to decide whether to use updateEntry() or addEntry(). For now only implement it for enums and arithmetic values, as they will mainly be used in populating templates.

We have some stream resolution which can provide slightly better frame duration than what we cap (i.e. 1/30 fps). The problem with this is CTS complains if the camera goes faster during the test than minFrameDuration reported for that resolution. For instance, 1080p minFrameDuration: - Nautilus : 33282000ns - Soraka : 33147000ns Both are less than capped minFrameDuration 1/30 fps (33333333.33ns).

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.

2021-10-19camera_device: Remove private scope of Camera3RequestDescriptorUmang Jain
Camera3RequestDescriptor is a utility structure that groups information about a capture request. It can be and will be extended to preserve the context of a capture overall. Since the context of a capture needs to be shared among other classes (for e.g. CameraStream) having a private definition of the struct in CameraDevice class doesn't help. Hence, de-scope the structure so that it can be shared with other components (through references or pointers). Splitting the structure to a separate file will help avoiding circular dependencies when using it through the HAL implementation.

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. ERROR Camera camera.cpp:1031 Request contains no buffers ERROR HAL camera_device.cpp:1109 '\_SB_.PCI0.I2C2.CAM0': Out-of-order completion for request 0x00007a1f1800ccd0 ERROR cros_camera_service[15706:15711]: [camera_device_adapter.cc(744)] (15711) Notify(): Fatal device error; aborting the camera service Revert the commit until a proper solution is implemented.

2021-10-15android: capabilities: Cap frame rate to 30 FPSJacopo Mondi
Limit the reported minumum frame duration to 30 FPS. The reason to do is to bring the libcamra HAL in par with the Intel HAL implementation on IPU3 platform, where 30FPS is the frame rate used to perform quality tuning in the closed-source IPA module and has been validated as the most efficient rate for the power/performace budget. This change bring into the HAL a platform specific constraints, which might be opportune for most platforms but should rather be configurable by system integrators. Record that with a \todo entry. Also record that, even if we report a lower frame rate, we currently do not limit what the camera actually produce.

2021-10-15android: capabilties: Fix ANDROID_CONTROL_AE_AVAILABLE_TARGET_FPS_RANGESJacopo Mondi
As reported by the CONTROL_AE_AVAILABLE_TARGET_FPS_RANGES documentation in the Android developer reference: "For devices advertising any color filter arrangement other than NIR, or devices not advertising color filter arrangement, this list will always include (min, max) and (max, max) where min <= 15 and max = the maximum output frame rate of the maximum YUV_420_888 output size." Collect the higher FPS of the larger YUV stream and use it with the minimum FPS rate the camera can produce to populate the ANDROID_CONTROL_AE_AVAILABLE_TARGET_FPS_RANGES static metadata.
