2021-08-30libcamera: framebuffer: Add assertion to detect offset is unfilledHirokazu Honda
The offset variable is introduced to FrameBuffer::Plane. In order to detect that the plane is used while the offset is not set, this adds the assertion to FrameBuffer::planes(). It should be removed in the future.

Therefore, if the v4l2 format single is single-planar format, the created number of FrameBuffer::Planes is 1.

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.

2021-08-16ipa: vimc: Send and retrieve FrameBuffers from IPAUmang Jain
Plumb through VIMC mojo interface to enable buffers passing. VIMC does not have parameters or statistics buffers but we can mimick the typical case of passing IPA buffers from pipeline handler to IPA using mock buffers. The mock IPA buffers are FrameBuffers which are dmabuf backed (in other words, mmap()able through MappedFramebuffer inside the IPA). This commits shows: - Passing the parameter buffer from the pipeline handler to the IPA through functions defined in mojom interface. - Passing request controls ControlList to the IPA. Any tests using VIMC will now loop in the IPA paths. Any tests running in isolated mode will help us to test IPA IPC code paths especially around (de)serialization of data passing from pipeline handlers to the IPA. Future IPA interface tests can simply extend the vimc mojom interface to achieve/test a specific use case as required.

2021-08-12libcamera: ipu3: Initialize controls in the IPAJacopo Mondi
All the IPU3 Camera controls are currently initialized by the pipeline handler which initializes them using the camera sensor configuration and platform specific requirements. However, some controls are better initialized by the IPA, which might, in example, cap the exposure times and frame duration to the constraints of its algorithms implementation. Also, moving forward, the IPA should register controls to report its capabilities, in example the ability to enable/disable 3A algorithms on request. Move the existing controls initialization to the IPA, by providing the sensor configuration and its controls to the IPU3IPA::init() function, which initializes controls and returns them to the pipeline through an output parameter. The existing controls initialization has been copied verbatim from the pipeline handler to the IPA, if not a for few line breaks adjustments and the resulting Camera controls values are not changed.

Introduce a new field in the controls serialization protocol to allow discerning which ControlIdMap a ControlInfoMap refers to. The newly introduced IdMapType enumeration describes the possible info maps: - Either the globally available controls::controls and properties::properties maps, which are valid across IPC boundaries - A ControlIdMap created locally by the V4L2 device, which is not valid across the IPC boundaries At de-serialization time the idMapType field is inspected and - If the idmap is a globally defined one, there's no need to create new ControlId instances when populating the de-serialized ControlInfoMap. Use the globally available map to retrieve the ControlId reference and use it. - If the idmap is a map only available locally, create a new ControlId as it used to happen before this patch. As a direct consequence, this change allows us to perform lookup by ControlId reference on de-serialized ControlIdMap that refers to the libcamera defined controls::controls and properties::properties.

2021-08-12libcamera: controls: Create ControlInfoMap with ControlIdMapJacopo Mondi
ControlInfoMap does not have a ControlId map associated, but rather creates one with the generateIdMap() function at creation time. As a consequence, when in the need to de-serialize a ControlInfoMap all the ControlId it contains are created by the deserializer instance, not being able to discern if the controls the ControlIdMap refers to are the global libcamera controls (and properties) or instances local to the V4L2 device that has first initialized the controls. As a consequence the ControlId stored in a de-serialized map will always be newly created entities, preventing lookup by ControlId reference on a de-serialized ControlInfoMap. In order to make it possible to use globally available ControlId instances whenever possible, create ControlInfoMap with a reference to an externally allocated ControlIdMap instead of generating one internally. As a consequence the class constructors take and additional argument, which might be not pleasant to type in, but enforces the concepts that ControlInfoMap should be created with controls part of the same id map. As the ControlIdMap the ControlInfoMap refers to needs to be allocated externally: - Use the globally available controls::controls (or properties::properties) id map when referring to libcamera controls - The V4L2 device that creates ControlInfoMap by parsing the device's controls has to allocate a ControlIdMap - The ControlSerializer that de-serializes a ControlInfoMap has to create and store the ControlIdMap the de-serialized info map refers to Signed-off-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

The Extensible and Extensible::Private classes contain pointers to each other. These pointers are initialized in the respective class's constructor, by passing a pointer to the other class to each constructor. This particular construct reduces the flexibility of the Extensible pattern, as the Private class instance has to be allocated and constructed in the members initializer list of the Extensible class's constructor. It is thus impossible to perform any operation on the Private class between its construction and the construction of the Extensible class, or to subclass the Private class without subclassing the Extensible class. To make the design pattern more flexible, don't pass the pointer to the Extensible class to the Private class's constructor, but initialize the pointer manually in the Extensible class's constructor. This requires a const_cast as the o_ member of the Private class is const.

2021-06-25libcamera/base: Introduce new base libraryKieran Bingham
The libcamera-base.so will feature internal support functionality that is utilised by libcamera, and can be shared in other places. This new library provides a layer beneath libcamera which provides common abstractions to internal objects. A pkg-config file is generated and named libcamera-base.pc which allows components such as external IPA modules to link directly to this library if they need. Normal applications will reference this library through the Requires: statement provided by the libcamera.pc package configuration, and linkage will be handled automatically through the pkg-config mechanisms. No code is moved to this library yet, this patch only introduces the framework, construction and linkage.

2021-06-25libcamera: Separate source and build path helpersKieran Bingham
The libcameraSourcePath and libcameraBuildPath helper functions are internal and specific to libcamera needs while operating with the meson build system. In preparation for the upcoming move of utils to a common library, move these helpers out of utils and into their own build unit.
