2021-10-07pipeline: raspberrypi: Create empty control lists correctlyDavid Plowman
When the pipeline handler start() method is supplied with a NULL list of controls, we send an empty control list to the IPA. When the IPA is running in isolated mode the control list goes through the data serializer, for which it must be marked correctly as a list of "controls::controls", otherwise the IPA process will abort. The IPA has a similar problem returning a control list in its configure() method. We must be careful to initialise it properly even when empty.

2021-10-06ipa: ipu3: awb: Introduce Black Level CorrectionJean-Michel Hautbois
The pixels output by the camera normally include a black level, because sensors do not always report a signal level of '0' for black. Pixels at or below this level should be considered black and to achieve that, we need to substract an offset to all the pixels. This can be taken into account by reading the lowest value of a special region on sensors which is not exposed to light. This provides a substracting factor to be able to adjust the expected black levels in the resulting images. For a camera outputting 10-bit pixel values (in the range 0 to 1023) a typical black level might be 64. It is a fixed value, obtained by capturing a raw frame with minimum exposure and gain fixed to 1.0 while covering the sensor (the darker the better). We consider it good enough as a very first approximation, until we measure it during a tuning process and include it in a configuration file Signed-off-by: Jean-Michel Hautbois <jeanmichel.hautbois@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

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.

2021-09-27libcamera: control_serializer: Separate the handles spaceJacopo Mondi
Two independent instances of the ControlSerializer class are in use at the IPC boundaries, one in the Proxy class that serializes data from the pipeline handler to the IPA, and one in the ProxyWorker which serializes data in the opposite direction. Each instance operates autonomously, without any centralized point of control, and each one assigns a numerical handle to each ControlInfoMap it serializes. This creates a risk of potential collision on the handle values, as both instances will use the same numerical space and are not aware of what handles has been already used by the instance "on the other side". To fix that, partition the handles numerical space by initializing the control serializer with a seed according to the role of the component that creates the serializer and increment the handle number by 2, to avoid any collision risk. While this is temporary and rather hacky solution, it solves an issue with isolated IPA modules without too much complexity added.

When a ControlList is deserialized, the code searches for a valid ControlInfoMap in the local cache and use its id map to initialize the list. If no valid ControlInfoMap is found, as it's usually the case for lists transporting libcamera controls and properties, the globally defined controls::controls id map is used unconditionally. This breaks the deserialization of libcamera properties, for which a wrong idmap is used at construction time. As the serialization header now transports an id_map_type field, store the idmap type at serialization time, and re-use it at deserialization time to identify the correct id map. Also make the validation stricter by imposing to list of V4L2 controls to have an associated ControlInfoMap available, as there is no globally defined idmap for such controls. To be able to retrieve the idmap associated with a ControlList, add an accessor function to the ControlList class. It might be worth in future using a ControlInfoMap to initialize the deserialized ControlList to implement controls validation against their limit. As such validation is not implemented at the moment, maintain the current behaviour and initialize the control list with an idmap.

2021-09-27ipa: proxy_worker: Reset ControlSerializer on workerJacopo Mondi
When running the IPA in isolated mode, each side of the IPC boundary has an instance of the ControlSerializer class which is used to serializer/deserialize controls before transmitting them on the wire. The IPAProxyWorker, which creates and manages the process the IPA runs in, does not reset its ControlSerializer upon an IPA::configure() call, while the IPAProxy does, effectively creating a misalignment between the two sides of the fence. This obviously creates issues as one side of the IPC runs with a populated and possibly stale cache of ControlInfoMap references, while the other side gets reset every time a new configuration is applied to the Camera. Fix that by resetting the IPAProxyWorker ControlSerializer on an IPA configure() call. This change fixes an issue which is easily triggered by running two consecutive capture sessions with the IPA running in isolated mode: ERROR Serializer control_serializer.cpp:520 Can't deserialize ControlList: unknown ControlInfoMap Fixes: 7832e19a599e ("utils: ipc: add templates for code generation for IPC mechanism") Signed-off-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2021-09-27libcamera: ipu3: Drop entityControls mapJacopo Mondi
The IPA::configure() function has an IPAConfigInfo parameters which contains a map of numerical indexes to ControlInfoMap instances. This is a leftover of the old IPA protocol, where it was not possible to specify a rich interface as it is possible today and each entity ControlInfoMap was indexed by a numerical id and stored in a map. Now that the IPA interface allows to specify parameters by name, drop the map and send the sensor's control info map only. If we'll need more ControlInfoMap to be shared with the IPA, a new parameter can be added to IPAConfigInfo.

2021-09-24libcamera: Standardize URLs to git repositoriesLaurent Pinchart
When the libcamera project was started, we had no public git tree hosted on git.libcamera.org. The problem has been addressed a while ago, and the git.linuxtv.org libcamera repository is now a mirror of the main git tree. The mirror is useful to benefit from the linuxtv.org automated compile tests, but it can also confuse users who don't know where the official version is. To try and clarify this, use the git.libcamera.org URL consistently through the project. This doesn't void the validatity of the linuxtv.org repository which will continue to mirror the libcamera.org repository.

Returning a non-managed pointer can cause leaks. Use a unique_ptr<> instead to avoid possible future issues. The std::move() for the planes argument to the FrameBuffer constructor is dropped as it's misleading. FrameBuffer has no constructor that takes an rvalue reference to planes, so the vector was copied despite the move. This only clarifies the intent, no functional change is introduced.

2021-09-23test: gstreamer: Simplify elements' ownershipsVedant Paranjape
In gstreamer, when elements are created, usually a floating [1] reference is returned which simply means, there is no ownership transfer (yet). Once can simply check for NULL and return through an error path, without bothering to clean up. Hence, g_autoptr is not much of help here. If the NULL checks have been passed successfully, elements are ready to use. However, we must claim ownership/reference it before using them via g_object_ref_sink(). This patch build upon this principle and removes the g_autoptr from gstreamer test base class (gstreamer_test.cpp) whereever necessary to tide up the code.
