2022-10-18utils: ipc: Add support for FlagsPaul Elder
Add Flags<E> as a supported type in the IPA interface. It is used in mojom with the [flags] attribute. Any field or parameter type E that is prefixed with the [flags] attribute will direct the code generator to generate the type name "Flags<E>" and appropriate serialization/deserialization code for Flags<E> instead of for E. It is usable and has been tested in struct members, function input and output parameters, and Signal parameters. This does not add support for returning Flags as direct return values. Additionally, the [scopedEnum] attribute can be used on enum definitions, which will instruct the code generator to convert it to an enum class instead of a raw enum.

Private members of the FrameBuffer class are split between FrameBuffer and FrameBuffer::Private. There was no real justification for this split, and keeping some members private in the FrameBuffer class causes multiple issues: - Future modifications of the FrameBuffer class without breaking the ABI may be more difficult. - Mutable access to members that should not be modified by applications require a friend statement, or going through the Private class.

2022-10-07libcamera: controls: Construct Span with size for array controlsLaurent Pinchart
The ControlList::set() function overload used for array controls constructs a Span from an initializer list. It doesn't specify the Span size explicitly, which results in a dynamic extent Span being constructed. That causes a compilation failure for fixed-size array controls, as they are defined as Control<T> with T being a fixed-extent Span, and conversion from a dynamic-extent to fixed-extent Span when calling ControlValue::set() can't be implicit. Fix this by constructing the Span using the size of the control, which resolves to a fixed-extent and dynamic-extent Span for fixed-size and dynamic-size array controls respectively. The ControlList::set() function that takes an initializer list can then be used for fixed-size array controls.

2022-09-08libcamera: v4l2_subdevice: Silence warning for unknown metadata formatsLaurent Pinchart
Commit e297673e7686 ("libcamera: v4l2_device: Adjust colorspace based on pixel format") has introduced a warning when trying to convert a color space from V4L2 to libcamera if the media bus code is unknown. This was meant to catch unknown image formats, but turned out to be also triggered for metadata formats. Color spaces are not applicable to metadata formats, there should thus be no warning. Fix it by skipping the color space translation and returning std::nullopt directly if the kernel reports V4L2_COLORSPACE_DEFAULT. This doesn't introduce any change in behaviour other than getting rid of the warning, as the V4L2Device::toColorSpace() function returns std::nullopt already in that case.

2022-09-01libcamera: color_space: Move color space adjustment to ColorSpace classUmang Jain
The CameraConfiguration::validateColorSpaces() function performs color space validation on a camera configuration, by validating the color space of each stream individually, and optionally ensuring that all streams share the same color space. The individual validation is very basic, limited to ensuring that raw formats use a raw color space. Color spaces are more constrained than that: - The Y'CbCr encoding and quantization range for RGB formats must be YcbcrEncoding::None and Range::Full respectively. - The Y'CbCr encoding for YUV formats must not be YcbcrEncoding::None. Instead of open-coding these constraints in the validateColorSpaces() function, create a new ColorSpace::adjust() function to centralize color space validation and adjustment, and use it in validateColorSpaces().

2022-08-25libcamera: color_space: Rename Jpeg to SyccLaurent Pinchart
The JPEG color space is badly name, as the JPEG specification (ITU-T T.81) doesn't define any particular color space: The interchange format does not specify a complete coded image representation. Application-dependent information, e.g. colour space, is outside the scope of this Specification. The JFIF specification (ITU-T T.871) is clearer as it requires ITU-R BT.601 YCbCr encoding and a full quantization range: The interpretations of Y, CB, and CR are derived from the E'Y, E'Cb, and E'Cr signals defined in the 625-line specification of Rec. ITU-R BT.601, but these signals are normalized so as to permit the usage of the full range of 256 levels of the 8-bit binary encoding of the Y component. It however doesn't specify color primaries or a transfer function explicitly. It only mentions the latter when describing the conversion from YCbCr to RGB: The inverse relationship for computing full scale 8-bit per colour channel gamma pre-corrected RGB values (following Rec. ITU-R BT.601 gamma pre-correction and colour primary specifications) from YCbCr colours (with 256 levels per component) can be computed as follows: [...] Given that ITU-R BT.601-5 (1995) didn't specify color primaries or a transfer function, and that the later ITU-R BT.601-7 (2011) version specifies color primaries for the 625-line variant that do not match sRGB, the JPEG color space in libcamera is badly named. This is confirmed by ITU-T T.871: As this Recommendation | International Standard is based on the prior informally-circulated JFIF version 1.02 specification that was produced in 1992, which referenced Rec. ITU-R BT.601 (formerly CCIR 601), it references that specification for definition of the E'Y, E'Cb, and E'Cr signals that correspond to the YCBCR values specified herein. However, since the development of the prior JFIF version 1.02 specification, additional industry specifications have been developed, Rec. ITU-R BT.601 has been updated, and common industry practice has emerged which often follows the sYCC specification in IEC 61966-2-1/Amd.1. The difference between the use of the colour interpretation specification in this Recommendation | International Standard and that of the sYCC specification may be considered negligible in practice. Rename the color space to sYCC, as its definition matches the sYCC standard, and indicate that it is typically used to encode JPEG images.

libcamera implements a pipeline handler locking mechanism based on advisory locks on media devices, to prevent concurrent access to cameras from the same pipeline handler from different processes (this only works between multiple libcamera instances, as other processes won't use advisory locks on media devices). A side effect of the implementation prevents multiple cameras created by the same pipeline handler from being used concurrently. Fix this by turning the PipelineHandler lock() and unlock() functions into acquire() and release(), with a use count to replace the boolean lock flag. The Camera class is updated accordingly. As a consequence of this change, the IPU3 pipeline handler will fail to operate properly when the cameras it exposes are operated concurrently. The android.hardware.camera2.cts.MultiViewTest#testDualCameraPreview test fails as a result. This should be fixed in the IPU3 pipeline handler to implement mutual exclusion between cameras.

Now that V4L2PixelFormat::fromPixelFormat() returns a list of formats to chose from, select the one supported by the video device by matching against the list of supported pixel formats. The first format found to match one of the device supported ones is returned. As the list of pixel formats supported by the video device does not change at run-time, cache it at device open() time.

2022-08-03libcamera: v4l2_videodevice: Reintroduce toV4L2PixelFormat()Jacopo Mondi
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().

2022-08-03libcamera: formats: Merge V4L2 single and multi formatsJacopo Mondi
To each libcamera PixelFormat two V4L2 formats are associated, the 'single' and 'multi' format variants. The two versions list plane contiguous and non-contiguous format variants, and an optional argument to V4L2PixelFormat::fromPixelFormat() was used to select which one to pick. In order to prepare to remove V4L2PixelFormat::fromPixelFormat(), and considering that no caller in the codebase uses the non-contiguous format variant, merge the two formats vectors in a single one and default the selection to the first available one, which is functionally equivalent to what is currently implemented.

2022-07-28libcamera: base: utils: Provide defopt to simplify std::optional::value_or() ↵Laurent Pinchart
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. Introduce a defopt variable that solves these issues by providing a value that can be passed to std::optional<T>::value_or() and get implicitly converted to a default-constructed T.

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.
