const Control< Span< const float > >	libcamera::controls::rpi::CnnOutputTensor
	This control returns a span of floating point values that represent the output tensors from a Convolutional Neural Network (CNN). The size and format of this array of values is entirely dependent on the neural network used, and further post-processing may need to be performed at the application level to generate the final desired output. This control is agnostic of the hardware or software used to generate the output tensors.

const Control< Span< const uint8_t > >	libcamera::controls::rpi::CnnOutputTensorInfo
	This control returns the structure of the CnnOutputTensor. This structure takes the following form:

const Control< bool >	libcamera::controls::rpi::CnnEnableInputTensor
	Boolean to control if the IPA returns the input tensor used by the CNN to generate the output tensors via the CnnInputTensor control. Because the input tensor may be relatively large, for efficiency reason avoid enabling input tensor output unless required for debugging purposes.

const Control< Span< const uint8_t > >	libcamera::controls::rpi::CnnInputTensor
	This control returns a span of uint8_t pixel values that represent the input tensor for a Convolutional Neural Network (CNN). The size and format of this array of values is entirely dependent on the neural network used, and further post-processing (e.g. pixel normalisations) may need to be performed at the application level to generate the final input image.

const Control< Span< const uint8_t > >	libcamera::controls::rpi::CnnInputTensorInfo
	This control returns the structure of the CnnInputTensor. This structure takes the following form:

const Control< Span< const int32_t, 2 > >	libcamera::controls::rpi::CnnKpiInfo
	This control returns performance metrics for the CNN processing stage. Two values are returned in this span, the runtime of the CNN/DNN stage and the DSP stage in milliseconds.

const std::array< const ControlValue, 3 >	libcamera::controls::rpi::SyncModeValues
	List of all SyncMode supported values.

const std::map< std::string, int32_t >	libcamera::controls::rpi::SyncModeNameValueMap
	Map of all SyncMode supported value names (in std::string format) to value.

const Control< int32_t >	libcamera::controls::rpi::SyncMode
	Enable or disable camera synchronisation ("sync") mode.

const Control< bool >	libcamera::controls::rpi::SyncReady
	When using the camera synchronisation algorithm, the server broadcasts timing information to the clients. This also includes the time (some number of frames in the future, called the "ready time") at which the server will signal its controlling application, using this control, to start using the image frames.

const Control< int64_t >	libcamera::controls::rpi::SyncTimer
	This reports the amount of time, in microseconds, until the "ready time", at which the server and client will signal their controlling applications that the frames are now synchronised and should be used. The value may be refined slightly over time, becoming more precise as the "ready time" approaches.

const Control< int32_t >	libcamera::controls::rpi::SyncFrames
	The number of frames the server should wait, after enabling SyncModeServer, before signalling (via the SyncReady control) that frames should be used. This therefore determines the "ready time" for all synchronised cameras.
