2021-10-06ipa: ipu3: Change limits and split loops in calculateBdsGrid()Jean-Michel Hautbois
The loops over the width and height of the image when calculating the BDS grid parameters are nested, but they're actually independent. Split them to reduce the complexity. While at it, split out the constants to documented const expressions for the grid sizes.

2021-10-05libcamera: Fix crash caused by reading uninitialised delayed controlsDavid Plowman
The cause is that we read out delayed values using a frame's sequence number (DelayedControls::get). But we fill the values up (DelayedControls::applyControls) incrementing writeCount by only one even if the sequence number has jumped by several since last time. This is exactly what happens when frames are being dropped. So the fix is to increment writeCount by "as much as the sequence number has jumped since last time", which means that we just follow the sequence number directly.

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.

The libcamera and libcamera-base libraries are currently unversioned, but donwstream users expect these to have a proper SONAME version in order to package them. A stable release has not yet happened because the project is still under development and the API/ABI might change. But having a versioned SONAME would allow distributions to package libcamera, without the need to add any downstream patch to set the version. Since the "0.0.0" version is already used in different places, let's also use that as the library version. The meson build system will use the first part of the version ("0") as the SONAME version, which is aligned with the convention used by other projects: $ ls /lib64/libcamera*so* -1 /lib64/libcamera-base.so /lib64/libcamera-base.so.0 /lib64/libcamera-base.so.0.0.0 /lib64/libcamera.so /lib64/libcamera.so.0 /lib64/libcamera.so.0.0.0 $ objdump -p /lib64/libcamera.so.0.0.0 | grep SONAME SONAME libcamera.so.0 Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

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.

Later the default value of the control has been added to the ControlInfo class, but the control serializer implementation has not been updated accordingly.

2021-09-27libcamera: control_serializer: Use the right idmapJacopo Mondi
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.

2021-09-14libcamera: v4l2_videodevice: Handle unexpected buffersKieran Bingham
A kernel bug can lead to unexpected buffers being dequeued where we haven't entered the buffer in our queuedBuffers_ list. This causes invalid accesses if not handled correctly within libcamera, and while it is a kernel issue, we can protect against unpatched kernels to provide a more suitable error message. This is fixed in the kernel by commit c592b46907ad ("media: videobuf2-core: dequeue if start_streaming fails") [0] [0] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c592b46907ad Handle unexpected buffers by returning a nullptr, and move cache management after the validation of the buffer.

2021-09-14ipa: ipu3: Clear incoming parameter use flagsKieran Bingham
The incoming params buffer may contain uninitialised data, or the parameters of previously queued frames. Clearing the entire buffer may be an expensive operation, and the kernel will only read from structures which have their associated use-flag set. It is the responsibility of the algorithms to set the use flags accordingly for any data structure they update during prepare(). Clear the use flags of the parameter buffer before passing the buffer to the algorithms during their prepare() operations.

Now that libcamera has the V4L2 format names, retrieve and report those names in ENUM_FMT. While at it, refactor the code slightly with PixelFormatInfo. This fixes the test failures on v4l2-compliance with the v4l2 compatilibity layer that were observed in version v4l2-compliance version 1.21.0-4838.

Some applications (like Firefox) run open() many times on video device nodes. This may lead to user confusion when they see "INFO V4L2Compat v4l2_compat_manager.cpp:146 No camera found for /dev/videoX" over and over again. Lower the log level to debug so that we can still get this information on debug, and so users won't see it all the time.
