2022-11-23ipa: rkisp1: add FrameDurationLimits controlNicholas Roth
Currently, the Android HAL does not work on rkisp1-based devices because required FrameDurationLimits metadata is missing from the IPA implementation. This change sets FrameDurationLimits for rkisp1 based on the existing ipu3 implementation, using the sensor's reported range of vertical blanking intervals with the minimum reported horizontal blanking interval.

2022-11-23ipa: rkisp1: Fail hard on empty CameraSensorInfoJacopo Mondi
The RkISP1 pipeline and IPA module allows for the CameraSensorInfo to be empty, probably to accommodate some sensor used in a test platform that does not provide the mandatory libcamera requirements. As the \todo item in the IPA reports, there is a possibility that the received CameraSensorInfo is empty and it should be checked before accessing it, but currently such requirement is not enforced in the code. This allows to assume all the test platforms in use have now successfully moved their sensor driver to comply with the minimum requirements and provide a populated CameraSensorInfo to the IPA. As the safety check is not enforced, and as we don't want to allow faulty sensors to send empty CameraSensorInfo to the IPA, remove the \todo item in the IPA and fail hard in the pipeline handler if the sensor does not comply with libcamera requirements.

2022-11-23ipa: rkisp1: Use IPAConfig in IPA::configure()Jacopo Mondi
The RkISP1 implementation of IPA::configure() still uses the legacy interface where sensor controls (and eventually lens controls) are passed from the pipeline handler to the IPA in a map. Since the introduction of mojom-based IPA interface definition, it is possible to define custom data types and use them in the interface definition between the pipeline handler and the IPA. Align the RkISP1 IPA::configure() implementation with the one in the IPU3 IPA module by using a custom data type instead of relying on a map to pass controls to the IPA.

2022-11-23libcamera: Move IPA sensor controls validation to CameraSensorJacopo Mondi
The CameraSensor class validates that the sensor driver in use supports the controls required for IPA modules to work correctly. For in-tree IPA modules, whose pipeline handlers already use CameraSensor there's no need to validate such controls again. Remove controls validation from the IPU3 and RkISP1 IPA modules and rely on CameraSensor doing that at initialization time. The list of mandatory controls is expanded to add V4L2_CID_ANALOGUE_GAIN without which IPA modules cannot function. The new requirement only applies to RAW sensors, platforms like UVC and Simple are not impacted by this change. While at it, expand the sensor driver requirements documentation to include V4L2_ANALOGUE_GAIN in the list of mandatory controls a sensor driver has to support.

The BufferMask enum provides a way of identifying which stream a frame buffer belongs to. This enum is defined in the raspberrypi.mojom interface file. However, the IPA does not need these enum definitions to mmap buffers that it uses. Move this enum out of the raspberrypi.mojom interface file and put it into the RPi namespace visible only to the pipeline handler.

2022-11-14Revert "pipeline: raspberrypi: Do not unconditionally free buffers on close"David Plowman
This reverts commit 30d704732badc675f72fe73d14749669cb645c23. It turns out that this commit causes some regressions and is in fact unnecessary because the related commit "libcamera: v4l2_videodevice: Guard against releasing unallocated buffers" (a2bdff6d0b67475492ac7cf9318866b6d89a28fd) fixes the problem completely (if the buffers were never allocated, the video device avoids trying to free them even if the pipeline handler asks). The reason for the regressions is that in this new (broken) scheme we would never call clearBuffers() on all the streams if the internal buffers were never allocated (i.e. buffersAllocated_ is never set). This causes the stream's bufferMap_ list to get longer and longer if there are multiple back-to-back calls to configure, and dev_->importBuffers() will ultimately to fail. So either we need to think more carefully about how to stop the pipeline handler from freeing buffers that it doesn't own, or we just leave it as the other commit resolves the problem on its own. In the interim, simply reverting this commit certainly seems like the best solution.

2022-11-14libcamera: v4l2_videodevice: Reduce zero sequence warning log levelKieran Bingham
The V4L2VideoDevice ensures that all sequence numbers for applications commence at zero from the libcamera perspective. This should be the behaviour expected by kernel drivers, but this is not always the case. This is handled internally to ensure consistency, and a warning is printed if the device does not start from zero. It was expected that the Warning would help highlight where kernel drivers should be fixed, but this has led to several false positive reports of failures where people have been concerned that this warning is a cause for unrelated issues. Lower the log level print to 'Info', to reduce the apparent severity of this warning. Info is likely more appropriate that Debug to continue to facilitate awareness of kernel drivers that could be improved, while not appearing to be a fault.

releaseBuffers() unconditionally calls ioctl(REQBUFS, 0) to release device buffer allocations through the close() and class destructor functions. If another libcamera process is running concurrently with a different sensor, it would cause the ioctl to fail in the kernel because the buffer queue is owned owned by the other process. This in turn would cause libcamera to generate an error log message. Fix this by ensuring the releaseBuffers() only calls ioctl(REQBUFS, 0) if there have been buffers previously allocated by the device.

2022-10-20libcamera: base: log: Fix LogCategory creation issuesTomi Valkeinen
Each declaration of a LogCategory will create a new LogCategory, and will be stored in an unordered_set Logger::categories_. This means that when a plugin .so is unloaded and loaded, as happens when destructing and creating a CamereManager, we'll get duplicate categories. The Logger::registerCategory docs say "Log categories must have unique names. If a category with the same name already exists this function performs no operation.". The code does not comply with this. We solve the issue with two changes: Change the unordered_set to a vector for simplicity, as there's no need for an unordered_set. Instead of using the LogCategory constructor to create new categories in _LOG_CATEGORY() macro, use a factory method. The factory method will return either an existing LogCategory if one exists with the given name, or a newly created one.

2022-10-13meson: Shared Object version handlingKieran Bingham
The libcamera project is not yet ready to declare ABI nor API stability, but it will benefit the community to be able to provide more regular release cycles to determine 'versioned' points of history. Ideally, these releases will be made at any ABI breakage, but can be made at arbitary time based points along the way. To support releases which may not be ABI stable, declare the soversion of both the libcamera and libcamera-base library to be dependant upon both the major minor and patch component of the project version. As part of this, introduce a new 'Versions' summary section to highlight the different version components that may become apparent within any given build. Bumping versions may leave dangling libcamera.so.* symlinks in build directories. This will confuse Doxygen which will print during its directory scanning phase a warning that the symlink can't be read. As we don't need Doxygen to follow symlinks, disable it with EXCLUDE_SYMLINKS.

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.

2022-10-05pipeline: raspberrypi: Update naming convention for tuning filesNaushir Patuck
Append "_mono" to the sensor name when generating the tuning filename for monochrome sensor variants. So the new naming convention is as follows: <sensor_name>.json - Standard colour sensor variant <sensor_name>_mono.json - Monochrome sensor variant Rename the existing imx296.json file to imx296_mono.json as this tuning file is based on the monochrome variant of the IMX296.

2022-10-04pipeline: raspberrypi: Detect monochrome "R" formats as being rawDavid Plowman
The "R" pixel formats (R8, R10, R10_CSI2P etc.) record the associated colour space as being YUV rather than RAW, meaning that the code was not detecting them as being raw formats. In the case of Raspberry Pi, we deal only with raw formats, so the revised test must work correctly for both these and the standard Bayer formats.

2022-10-04libcamera: v4l2_device: List controls when setting file descriptorLaurent Pinchart
The base V4L2Device class is bound to a video device node by either open(), which opens the device node and creates a new file descriptor, or setFd(), which takes an already open file descriptor. The former populates the V4L2Device instance controls, while the latter doesn't. This prevents using controls on V4L2 M2M devices. Fix it by populating controls in setFd(), which is called by open().

2022-09-29libcamera: v4l2_device: Log control id instead of errorIdxUmang Jain
v4l2_ext_controls.errorIdx (in the case of single failing control for VIDIOC_*_EXT_CTRLS calls) represents the index of that control. Since it is a single control, we can print the control id rather than its index. This improves logging as the id can be easily co-related with the controls while reading the log.

2022-09-23pipeline: raspberrypi: Improve Unicam timeout handlingNaushir Patuck
Currently, if a Unicam timeout is signalled, the pipeline handler only raises an error message. Update the error handling to put the pipeline handler in an internal error state, disable all device streams, and return all outstanding requests as cancelled. Any subsequent requests that come into the pipeline handler will also be returned as cancelled. Any further error handling (e.g. a reset with camera stop()/start()) is up to the application to perform as it requires.

2022-09-12libcamera: control_serializer: store/load all ControlValue typesChristian Rauch
The min/max/def ControlValue of a ControlInfo can take arbitrary types that are different from each other and different from the ControlId type. The serialiser serialises these ControlValue separately by their type but does not store the type. The deserialiser assumes that ControlValue types match the ControlId type. If this is not the case, deserialisation will try to deserialise values of the wrong type. Fix this by serialising each of the min/max/def ControlValue's ControlType and storing it just before the serialised ControlValue.
