2021-01-18libcamera: camera_sensor: Validate driver supportJacopo Mondi
The CameraSensor class requires the sensor driver to report information through V4L2 controls and through the V4L2 selection API, and uses that information to register Camera properties and to construct CameraSensorInfo class instances to provide them to the IPA. Currently, validation of the kernel support happens each time a feature is requested, with slighly similar debug/error messages output to the user in case a feature is not supported. Rationalize this by validating the sensor driver requirements in a single function Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com> Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>

2020-11-07libcamera: v4l2_videodevice: Zero-initialize planes in V4L2DeviceFormatLaurent Pinchart
The V4L2DeviceFormat class doesn't have a default constructor, neither does it specifies default member initializers for the plane-related members. This results in the planes array and planesCount members being uninitialized by default, leading to undefined behaviour if the user of the class doesn't initialize it explicitly. Most users initialize V4L2DeviceFormat instances, but some don't. We could fix them, but that would likely turn into a game of whack-a-mole. As there's no use case for instantiating a large number of V4L2DeviceFormat instances in a performance-critical code path, let's instead add default initializers to avoid future issues. While at it, define a type of the structures containing plane information, and use an std::array.

The C++20 std::span class, after which Span is modelled, specifies four constructors as explicit when extent is not dynamic_extent. Align our implementation with those requirements. A careful reviewer may notice that this change addresses five constructors, not four. The reason is that the two constructors taking Container and const Container parameters are not specified in C++20, which uses a single constructor taking a range parameter instead. As ranges are not available in C++17, the Container constructors are our best effort at providing a similar feature.

2020-10-26libcamera: controls: Disable ControlValue<T> construction from unsupported TLaurent Pinchart
The ControlValue<T> constructor for non-array values is a template function that participates in overload resolution for all T types that are not Span or std::string. Other T types that are not supported then result in a compilation error. This causes issues when calling an overloaded function that can accept both a ControlValue and a Span with an std::array<U> parameter. The first overload will be resolved using implicit construction of a ControlValue from the std::array<U>, while the second overload will be resolved using implicit construction of a Span<U> from the std::array<U>. This results in a compilation error due to an ambiguous function call. The first overload is invalid, selecting it would result in a compilation error in the ControlValue constructor, as the ControlValue<T> constructor doesn't support std::array<U> for type T. The compiler can't know about that, as overload resolution happens earlier. To fix it, we can disable the ControlValue<T> constructor for unsupported types T, moving the type check from compilation of the function to overload resolution. The constructor will not participate in overload resolution, and the call won't be ambiguous. The end result is the same for unsupported types, compilation will fail.
