2023-05-01meson: Ignore -Wredundant-move with gcc-13 and newerLaurent Pinchart
Starting from 13.1, gcc implements the C++23 version of automatic move from local variables in return statements (see https://en.cppreference.com/w/cpp/language/return). As a result, some previously required explicit `std::move()` in return statements generate warnings. This is the case when a function returns an object whose type is a class derived from the class type the function returns: struct U { }; struct T : U { }; U f() { T t; return t; } Up to C++20, the automatic move from local variables selects the move constructor of class U, which is not the move constructor of the expression. Overload resolution is then performed a second time, with t considered as an lvalue. An explicit `std::move(t)` is needed in the return statement to select the U move constructor. Starting from C++23, `t` is treated as an xvalue, and the U move constructor is selected without the need for an explicit `std::move(t)`. An explicit `std:move()` then generates a redundant-move warning, as in the valueOrTuple() function in src/py/libcamera/py_helpers.cpp. Omitting the `std::move()` silences the warning, but selects the copy constructor of U with older gcc versions and with clang, which negatively impacts performance. The easiest fix is to disable the warning. With -Wpessimizing-move enabled, the compiler will still warn of pessimizing moves, only the redundant but not pessimizing moves will be ignored.

2023-04-30libcamera: imx8-isi: Split Bayer/YUV config generationJacopo Mondi
At generateConfiguration() a YUV/RGB pixel format is preferred for the StillCapture/VideoRecording/Viewfinder roles, but currently there are no guarantees in place that the sensor provides a non-Bayer bus format from which YUV/RGB can be generated. This makes the default configuration generated for those roles not to work if the sensor is a RAW-only one. To improve the situation split the configuration generation in two, one for YUV modes and one for Raw Bayer mode. StreamRoles assigned to a YUV mode will try to first generate a YUV configuration and then fallback to RAW if that's what the sensor can provide. As an additional requirement, for YUV streams, the generated mode has to be validated with the sensor to confirm the desired sizes can be generated as the ISI cannot up-scale. In order to test a format use the newly introduced CameraSensor::tryFormat().

2023-04-30libcamera: imx8-isi: Break out YUV format selectionJacopo Mondi
As per the RAW format selection, the media bus format selection procedure relies on the direct association of PixelFormat and media bus code in the formatsMap_ map. As the ISI can generate YUV and RGB formats from any non-Bayer media bus format, break out the YUV/RGB media bus format selection to a separate function. The newly introduced getYuvMediaBusFormat() tests a list of known-supported media bus formats against the list of media bus formats supported by the sensor and tries to prefer media bus codes with the same encoding as the requested PixelFormat. Use the newly introduced function in ISICameraConfiguration::validateYuv() to make sure the sensor can produce a YUV/RGB media bus format.

2023-04-30libcamera: imx8-isi: Break out RAW format selectionJacopo Mondi
The current implementation of the ISI pipeline handler handles translation of PixelFormat to media bus formats from the sensor through a centralized map. As the criteria to select the correct media bus code depends on if the output PixelFormat is a RAW Bayer format or not, start by splitting the RAW media bus code procedure selection out by adding a function for such purpose to the ISICameraData class. Add the function to the ISICameraData and not to the ISICameraConfiguration because: - The sensor is a property of CameraData - The same function will be re-used by the ISIPipelineHandler during CameraConfiguration generation.

In `udevNotify()`, constructing an std::string from the device's associated action is unnecessary as it is only compared against static strings, and for that purpose an std::string_view works just as well, while being cheaper to construct. In the same vein, an std::string_view can be used to store the device's devnode initially, and the string construction can be deferred until it is needed. Furthermore, previously `udev_device_get_devnode()` was called twice. The extra call is now removed.

Make a copy of the CameraMode structure on a switch mode call. This replaces the existing lastSensitivity_ field. Limit the AGC gain calculations to the minimum value given by the CameraMode structure. The maximum value remains unclipped as any gain over the sensor maximum will be made up by digital gain. Rename clipShutter to limitShutter for consistency, and have the latter limit the shutter speed to both upper and lower bounds.

When an executable using libcamera calls exec(3) while a camera is in use, file descriptors corresponding to the V4L2 video devices are kept open has they have been created without O_CLOEXEC. This results in the video devices staying busy, preventing the new executable from using them: [91] ERROR V4L2 v4l2_videodevice.cpp:1047 /dev/video0[149:cap]: Unableto set format: Resource busy Fix this by opening video devices with O_CLOEXEC, which is generally a good idea in libraries.

2023-03-21libcamera: camera: Ensure queued requests are invalidKieran Bingham
Invalid, or not correctly reset requests can cause undefined behaviour in the pipeline handlers due to unexpected request state. If the status has not been reset to Request::RequestPending, it is either not new, or has not been correctly procesed through Request::reuse(). This can be caught early by validating the status of the request when it is queued to a camera. Reject invalid requests before processing them in the pipeline handlers.

2023-03-21py: cam: Fix demosaic overflow issueTomi Valkeinen
The demosaic code first expands the buffer datatype to uint16, and then shifts the data left so that the 8, 10 and 12 bitspp formats all become 16 bitspp. It then, eventually, uses np.einsum to calculate averages, but this averaging sums multiple uint16 values together, and stores them in uint16 storage. As in the first step we shifted the values left, possibly getting values close to the maximum of uint16 range, we, of course, overflow when summing them together. This leads to rather bad looking images. Fix this by dropping the original shift. It serves no purpose, and is probably a remnant of some early testing code. This way the largest numbers we are summing together are 12 bit values, and as we use a 3x3 window from which we fetch values, for a single rgb plane, the max number of 12 bit values is 5 (for green). Sum of 5 12 bit values is well below the 16 bit maximum.

The ConverterFactoryBase::create() function returns a nullptr when no converter is found. The only caller, SimpleCameraData::init(), checks if the converter is valid with isValid(), but doesn't check if the pointer is null, which can lead to a crash. We could check both pointer validity and converter validity in the caller, but to limit the complexity in callers, it is better to check the converter validity in the create() function and return a null pointer when no valid converter is found.

Some updates to the tuning for the imx296 sensors.

Thanks to Dr. Rolf Henkel for these measurements and calculations. * Sharpening has been toned down quite a lot. * rpi.focus algorithm added so that the focus measure can be accessed. The sharpening and focus changes are applied to the mono version of the sensor too as we expect similar characteristics.
