2023-03-09libcamera: converter: Check converter validitySuhrid Subramaniam
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. For the colour variant: * Minor change to the AWB curve, making things a little less green. * Updated CCMs that reduce colour saturation to a more accurate level. 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.

2023-03-07pipeline: raspberrypi: Iterate over all Unicam instances in match()Naushir Patuck
On Raspberry Pi Compute Module platforms, it is possible to attach a single camera device only to the secondary Unicam port. The current logic of PipelineHandlerRPi::match() will return a failure during enumeration of the first Unicam media device (due to no sensor attached, or sensor failure) and thus the second Unicam media device will never be enumerated. Fix this by looping over all Unicam instances in PipelineHandlerRPi::match() until a camera is correctly registered, or return a failure otherwise.

2023-03-07pipeline: raspberrypi: Add a Unicam timeout override config optionsNaushir Patuck
Add a new parameter to the pipeline handler config file named "unicam_timeout_value_ms" to allow users to override the automatically computed Unicam timeout value. This value is given in milliseconds, and setting a value of 0 (the default value) disables the override. An example use of this parameter would be if an application configured a RAW stream, and provides buffers for the stream on every request. If the application holds off on sending requests for a particular reason (e.g. a timelapse use case), then we will possibly hit the watchdog timeout as it is only a small multiple of the frame length. This override allows an application to select a larger value with the knowledge that it may space requests longer than the calculated timeout value.

2023-03-07ipa: raspberrypi: Better heuristics for calculating Unicam timeoutNaushir Patuck
The existing mechanism of setting a timeout value simply uses the maximum possible frame length advertised by the sensor mode. This can be problematic when, for example, the IMX477 sensor can use a frame length of over 600 seconds. However, for typical usage the frame length will never go over several 100s of milliseconds, making the timeout very impractical. Store a list of the last 10 frame length values requested by the AGC. On startup, and at the end of every frame, take the maximum frame length value from this list and return that to the pipeline handler through the setCameraTimeoutValue() signal. This allows the timeout value to better track the actual sensor usage.

2023-01-30ipa: raspberrypi: First version of autofocus algorithm using PDAFNick Hollinghurst
Provide the first version of the Raspberry Pi autofocus algorithm. This implementation uses a hybrid of contrast detect autofocus (CDAF) and phase detect autofocus (PDAF) statistics. PDAF is always preferred over CDAF due to having less "hunting" behavior.

Add a new AfAlgorithm class that defines the interface for the Raspberry Pi autofocus algorithm. Add an AfStatus structure that returns the results of the autofocus algorithm back to the IPA. Add a structure for PDAF statistics provided by supported sensors for use with an autofocus algorithm. This structure is currently based on the IMX708's PDAF "Type 1" statistics.
