Implement the core of libtuning, our new tuning tool infrastructure. It leverages components from raspberrypi's ctt that could be reused for tuning tools for other platforms. The core components include: - The Image class - libtuning (entry point and other core functions) - macbeth-related tools, including the macbeth reference image - utils Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2022-11-24libcamera: tracing: fix header generation when built as subprojectBarnabás Pőcze
Building libcamera as a subproject is failing when tracepoints are enabled due to incorrectly managing the relative paths between the source and build directory while generating tracepoint headers. The previously used path = output.replace('include/', '', 1) logic is not sufficient to correctly determine the proper path when libcamera is built as a subproject, and does not correctly handle the relative paths, causing path to be processed as: 'subprojects/libcamera/include/libcamera/internal/tracepoints.h'.replace('include/', '', 1) which evaluates to 'subprojects/libcamera/libcamera/internal/tracepoints.h' so the tracepoints.h header file will try to include: #define TRACEPOINT_INCLUDE "subprojects/libcamera/libcamera/internal/tracepoints.h" which will fail. Fix it by using Python's pathlib to calculate the relative path of the output file with respect to the "include" directory of libcamera. This has been tested with Pipewire. For non-subproject builds it should generate the exact same path that was previously generated.

2022-10-18utils: ipc: Allow the skipHeader attribute on enumsPaul Elder
Currently, enums that are passed between pipeline handlers and their IPA must be defined in a mojom file. However, there is a use case for enum/flags to be defined in a C++ header, such that the enum can be used in a component other than the pipeline handler and its IPA. To support this, add support for the skipHeader attribute for enums. Like structs, it is only allowed in core.mojom.

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.

Array controls specify the array size through the YAML 'size' element, which stores a list of values, one per dimension. Variable-size arrays currently use an empty 'size' list, which prevents describing the number of dimensions of the array. Improve this by using the same notation for fixed-size and variable-size array controls. Dimensions that are not fixed are described as a string instead of an integer, such as [n], [n,3] or [w,h].

The DNG specification is based on the TIFF file format and recommends storing the raw image data in a SubIFD and the Exif tags in an Exif IFD. Other options are allowed, even if not recommended, such as storing both the raw image data and the Exif data in IFD0, as done by the TIFF/EP specification. libcamera-apps use pyexiv2 to produce DNG files, following the DNG recommendation, while applications based on picamera2 use PiDNG, which adopts the TIFF/EP structure. Why it does so is not currently clear (see https://github.com/schoolpost/PiDNG/issues/65 for discussions on this topic), but as files based on the DNG and TIFF/EP variants exist in the wild, both need to be supported by ctt.

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 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.

2021-09-02libcamera: Drop emitter object pointer from signal argumentsLaurent Pinchart
Many signals used in internal and public APIs carry the emitter pointer as a signal argument. This was done to allow slots connected to multiple signal instances to differentiate between emitters. While starting from a good intention of facilitating the implementation of slots, it turned out to be a bad API design as the signal isn't meant to know what it will be connected to, and thus shouldn't carry parameters that are solely meant to support a use case specific to the connected slot. These pointers turn out to be unused in all slots but one. In the only case where it is needed, it can be obtained by wrapping the slot in a lambda function when connecting the signal. Do so, and drop the emitter pointer from all signals. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com>

2021-08-19ipa: Use FileDescriptor instead of int in layers above IPC payloadPaul Elder
Regarding (de)serialization in isolated IPA calls, we have four layers: - struct - byte vector + fd vector - IPCMessage - IPC payload The proxy handles the upper three layers (with help from the IPADataSerializer), and passes an IPCMessage to the IPC mechanism (implemented as an IPCPipe), which sends an IPC payload to its worker counterpart. When a FileDescriptor is involved, previously it was only a FileDescriptor in the first layer; in the lower three it was an int. To reduce the risk of potential fd leaks in the future, keep the FileDescriptor as-is throughout the upper three layers. Only the IPC mechanism will deal with ints, if it so wishes, when it does the actual IPC. IPCPipeUnixSocket does deal with ints for sending fds, so the conversion between IPCMessage and IPCUnixSocket::Payload converts between FileDescriptor and int. Additionally, change the data portion of the serialized form of FileDescriptor to a 32-bit unsigned integer, for alightnment purposes and in preparation for conversion to an index into the fd array. Also update the deserializer of FrameBuffer::Plane accordingly.
