Define the Soft IPA main and event interfaces, add the Soft IPA implementation. The current src/ipa/meson.build assumes the IPA name to match the pipeline name. For this reason "-Dipas=simple" is used for the Soft IPA module. Auto exposure/gain and AWB implementation by Dennis, Toon and Martti. Auto exposure/gain targets a Mean Sample Value of 2.5 following the MSV calculation algorithm from: https://www.araa.asn.au/acra/acra2007/papers/paper84final.pdf Use CameraSensorHelper to convert the analogue gain code read from the camera sensor into real analogue gain value. In the future this makes it possible to use faster AE/AGC algorithm. Right now the CameraSensorHelper lets us use the full range of analogue gain values. If there is no CameraSensorHelper for the camera sensor in use, a warning log message is printed.

2024-03-15libcamera: v4l2_subdevice: Add V4L2Subdevice::Route structureLaurent Pinchart
The V4L2Subdevice class deals with streams in two places: - In routing tables, streams as expressed as a pad number and a stream number in a v4l2_subdev_route instance. - In the format and selection get and set functions, streams as expressed using the Stream structure, which binds the pad number and stream number. Expressing streams in different ways requires pipeline handlers and other helpers to convert between the two representations. This isn't much of an issue yet as libcamera has little stream-aware code, but it is expected to increasingly become a burden. To simplify the API, introduce a V4L2Subdevice::Route structure that mimicks the kernel v4l2_subdev_route structure but represents streams as V4L2Subdevice::Stream instances. This will improve seamless integration of routes, formats and selection rectangles.

Add a Stream structure to identify a subdev pad and stream, and use it to extend the V4L2Subdevice functions that get and set formats and selection rectangles with stream support. To preserve the existing pad-based API, implement overloaded functions that wrap the new stream-based API.

Several functions in libcamera classes are marked as thread-bound, restricting the contexts in which those functions can be called. There is no infrastructure to enforce these restrictions, causing difficult to debug race conditions when they are not met by callers. As a first step to solve this, add an assertThreadBound() protected function to the Object class to test if the calling thread context is valid, and use it in member functions of Object subclasses marked as thread-bound. This replaces manual tests in a few locations. The thread-bound member functions of classes that do not inherit from Object are not checked, and neither are the functions of classes marked as thread-bound at the class level. These issue should be addressed in the future. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Milan Zamazal <mzamazal@redhat.com>

Label draft controls and properties through the "draft" vendor tag and deprecate the existing "draft: true" mechanism. This uses the new vendor tags mechanism to place draft controls in the same libcamera::controls::draft namespace and provide a defined control id range for these controls. This requires moving all draft controls from control_ids.yaml to control_ids_draft.yaml. One breaking change in this commit is that draft control ids also move to the libcamera::controls::draft namespace from the existing libcamera::controls namespace. This is desirable to avoid API breakages when adding new libcamera controls.

2023-10-18build: ipa: Fix bug in building multiple IPA interfaces with the same mojom fileNaushir Patuck
In the existing meson scripts, an IPA mojom interface file may not be built if: - There are duplicate entries for the mojom file shared by different pipeline handlers in pipeline_ipa_mojom_mapping, and - The IPA is not listed first in pipeline_ipa_mojom_mapping, and - The first listed IPA for the given mojom file is not selected in the build. Fix this by using a separate list of already built mojom files (mojoms_built) instead of overloading use of the existing ipa_mojom_files list. Now, ipa_mojom_files gets filled in outside of the IPA list enumeration loop, this also guarantees the IPA documentation gets built even if the pipeline is not selected.

The CameraManager::get(dev_t) implementation was provided only for the V4L2 Adaptation layer. This has now been replaced with the use of the public SystemDevices property. Remove the deprecated function entirely, along with the camerasByDevnum_ map which was only used to support this functionality. This is a clear (and intentional) breakage in both the API and ABI.

2023-07-05apps: Add ipa-verify applicationLaurent Pinchart
When packaging libcamera, distributions may break IPA module signatures if the packaging process strips binaries. This can be fixed by resigning the modules, but the process is error-prone. Add a command line ipa-verify utility that tests the signature on an IPA module to help packagers. The tool takes a single argument, the path to an IPA module shared object, and expects the signature file (.sign) to be in the same directory. In order to access the public key needed for signature verification, add a static function to the IPAManager class. As the class is internal to libcamera, this doesn't affect the public API.

2023-07-04libcamera: Remove `StreamRoles` aliasBarnabás Pőcze
Now that `Camera::generateConfiguration()` takes a `libcamera::Span` of `StreamRole`, remove the `StreamRoles` type, which was an alias to `std::vector<libcamera::StreamRole>`. The removal has two reasons: - it is no longer strictly necessary, - its presence may suggest that that is the preferred (or correct) way to build/pass a list of `StreamRole`.

2023-07-04libcamera: camera: Take span of StreamRole instead of vectorBarnabás Pőcze
Change the parameter type of `generateConfiguration()` from `const std::vector&` to `libcamera::Span`. A span is almost always preferable to a const vector ref because it does not force dynamic allocation when none are needed, and it allows any contiguous container to be used. A new overload is added that accepts an initializer list so that cam->generateConfiguration({ ... }) keeps working. There is no API break since a span can be constructed from a vector and the initializer list overload takes care of the initializer lists, but this change causes an ABI break.
