2022-08-04libcamera: Switch internal YAML files to YAML 1.1Laurent Pinchart
The python3-yaml package (containing the PyYAML Python package) shipped by Debian stable is documented as a YAML 1.1 parser: Python3-yaml is a complete YAML 1.1 parser and emitter for Python3. PyYAML doesn't implement YAML 1.2 support, but ignores the minor number of the YAML directive, and thus doesn't choke on the libcamera internal files used to generate format- and control-related source code that explicitly state conformance with YAML 1.2. Still, given that we don't use any feature of YAML 1.2, and that the tuning data files now use YAML 1.1, switch the internal YAML files to version 1.1 as well for consistency. The main drawback of YAML 1.1 is that the unquoted literal strings Yes, No, On and Off will be parsed as booleans. We need to be careful to avoid those values in YAML files, until libcamera can switch to YAML 1.2 once more recent versions of libyaml get shipped by the distributions we want to support. This is however not an issue introduced by this change, as the existing YAML 1.2 files were parsed with the YAML 1.1 string literal parsing rules anyway.

2022-08-04ipa: rkisp1: Use YAML 1.1 for tuning data filesLaurent Pinchart
YAML 1.2 support has been added in libyaml in version 0.2.3. Debian stable ships version 0.2.2 of libyaml, which causes parse errors of the tuning tuning data files due to the YAML 1.2 directive at the beginning. As we don't use any feature of YAML 1.2, downgrade the data files to YAML 1.1.

2022-08-04pipeline: rkisp1: Move ControlInfoMap to IPA moduleLaurent Pinchart
Currently the pipeline handler advertises controls handled by the IPA from a ControlInfoMap it manually constructs. This is wrong, as the IPA module is the component that knows what controls it supports. Fix this by moving the ControlInfoMap construction to the IPA module, and pass it to the pipeline handler as a return value from the IPA init() function.

2022-08-03libcamera: pipeline: simple: Add support for NXP ISILaurent Pinchart
Several NXP i.MX8 SoCs (such as the i.MX8MN and i.MX8MP) contain a camera pipeline made of sensor interfaces (with parallel and/or CSI-2 receivers) and an image processing engine named ISI. The ISI contains an input crossbar switch and one or more processing pipelines capable of format conversion and scaling. This is a good candidate for the simple pipeline handler as a first step. The i.MX8MP should eventually graduate to having its own pipeline handler as it also contains two ISP instances (supported by the rkisp1 driver).

2022-08-03libcamera: pipeline: simple: Walk pipeline using subdev internal routingPhi-Bang Nguyen
When traversing the media graph to discover a pipeline from the camera sensor to a video node, all sink-to-source paths inside subdevs are considered. This can lead to invalid paths being followed, when a subdev has restrictions on its internal routing. The V4L2 API supports exposing subdev internal routing to userspace. Make use of this feature, when implemented by a subdev, to restrict the internal paths to the currently active routes. If a subdev doesn't implement the internal routing operations, all source pads are considered, as done today. This change is needed to properly support multiple sensors with devices such as the NXP i.MX8 ISI or the MediaTek i350 and i500 SENINF. Support for changing routes dynamically will be added later when required.

2022-08-03libcamera: pipeline: simple: Setup links in the context of sink entitiesLaurent Pinchart
To setup links the pipeline handler iterates over all entities in the pipeline and disables all links but the ones we want to enable. Some entities don't allow multiple sink links to be enabled, so the iteration needs to be based on sink entities, disabling all their links first and then enabling the sink link that is part of the pipeline. The loop implementation iterates over all Entity instances, and uses their source link to locate the MediaEntity for the connected sink. The sink entity is then processed in the context of the source's loop iteration. This prevents the code from being able to access extra information about the sink entity, as we only have access to the MediaEntity, not the Entity. To prepare for subdev routing support that will require accessing additional entity information, refactor the loop to process the sink entity in the context of its Entity instance.

This is a partial revert of commit 395d43d6d75b ("libcamera: v4l2_videodevice: Drop toV4L2PixelFormat()") The function was removed because it incorrectly maps non-contiguous V4L2 format variants (ie V4L2_PIX_FMT_YUV420M) to the API version supported by the video device (singleplanar API and multiplanar API). It was decided at the time to remove the function and let its users call directly V4L2PixelFormat::fromPixelFormat() which accepts a 'multiplanar' flags. As we aim to associate multiple V4L2PixelFormat to a single libcamera format, the next patches will verify which of them is actually supported by the video device. For now, return the contiguous version unconditionally. Re-introduce V4L2VideoDevice::toV4L2PixelFormat() and convert all the V4L2PixelFormat::fromPixelFormat() users to use it. The V4L2 compatibility layer is the only outlier as it doesn't have a video device to poke, hence it still uses V4L2PixelFormat::fromPixelFormat(). Next patches will implement the device format matching logic and handle the non-contiguous plane issue in V4L2VideoDevice::toV4L2PixelFormat().

usage The std::optional<T>::value_or(U &&default_value) function returns the contained value if available, or default_value if the std::optional has no value. If the desired default value is a default-constructed T, the obvious option is to call std::optional<T>::value_or(T{}). This approach has two drawbacks: - The \a default_value T{} is constructed even if the std::optional instance has a value, which impacts efficiency. - The T{} default constructor needs to be spelled out explicitly in the value_or() call, leading to long lines if the type is complex.

In order to remove this reliance on the parser to provide ordering, introduce a new version 2.0 format for the camera tuning file. In this version, the algorithms are specified in a top level list node ("algorithms"), which does require strict ordering of the elements. A "version" node is added to distinguish between the version 1.0 and 2.0 formats. The absence of the "version" node implies version 1.0. A "target" node is also added to specify the target platform for this configuration. Update the controller to support either version of the tuning file by looking at the version node.

2022-07-28libcamera: yaml_parser: Preserve order of items in dictionaryLaurent Pinchart
The std::map container used to store dictionary items in YamlObject doesn't preserve the YAML data order, as maps are ordered by key, not by insertion order. While this is compliant with the YAML specification which doesn't guarantee ordering of mappings, the Raspberry Pi IPA relies on elements being ordered as in the YAML data. To replace the dependency on boost with the YamlParser class, we thus need to guarantee that the order is preserved. Preserve the order by storing items in list_ unconditionally. Turn the list_ vector from storing YamlObject unique pointers to storing key-value pairs, with the key being absent when the object is a list, not a dictionary. The YamlObject implementation is updated to preserve the existing API, with the only difference being that YamlObject::memberNames() now returns member names in the same order as in the YAML file. The ordering is an implementation detail, so changing it doesn't violate the YAML specification. The documentation is not updated to reflect this, as we don't want any new user to rely on a particular ordering. This commit could be reverted if desired when the Raspberry Pi IPA updates to a new tuning data format and drops support for the old format.

2022-07-28libcamera: yaml_parser: Replace ok flag to get() with std::optionalLaurent Pinchart
The YamlObject::get() function takes a default value and an optional bool ok flag to handle parsing errors. This ad-hoc mechanism complicates error handling in callers. A better API is possible by dropping the default value and ok flag and returning an std::optional. Not only does it simplify the calls, it also lets callers handle errors through the standard std::optional class instead of the current ad-hoc mechanism. Provide a get() wrapper around std::optional::value_or() to further simplify callers that don't need any specific error handling.
