2020-12-08libcamera: ipa: Pass a set of controls and return results from ipa::start()Naushir Patuck
This change allows controls passed into PipelineHandler::start to be forwarded onto IPAInterface::start(). We also add a return channel if the pipeline handler must action any of these controls, e.g. setting the analogue gain or shutter speed in the sensor device. The IPA interface wrapper isn't addressed as it will soon be replaced by a new mechanism to handle IPC.

2020-12-07pipeline: ipa: raspberrypi: Handle failures during IPA configurationNaushir Patuck
If the IPA fails during configuration, return an error flag to the pipeline handler and fail the use case gracefully. At present, the IPA configuration can fail for the following reasons: - The sensor is not recognised, and fails to open a CamHelper object. - The pipeline handler did not pass in controls for the ISP and sensor.

2020-12-01src: ipa: raspberrypi: Fix initial AGC oscillation for imx219 sensorDavid Plowman
The exposure times in the exposure modes were causing AGC oscillations because the algorithm was demanding long unachievable exposure times but, without working sensor metadata, thought it was getting them when actually it was not. We fix it by making the exposure profile request only achievable exposure times, as we do for the ov5647 tuning.

AGC, when paused, sets the last exposure/gain it wrote to be its "fixed" values and will therefore continue to return them. When resumed, we clear them so that both will float again. This approach is better because AGC can be paused and we can subsequently change (for example) the exposure and the gain won't float again.

This fixes a bug where the luminance correction table was not being resampled according to the camera mode, in the same way as the colour tables. This could be noticeable if any camera modes crop aggressively. This resampling can be done "up front" in the SwitchMode, as we have only a single fixed luminance table. In order to protect the recalculation of the table from the asynchronous thread (which reads it) I've elected to wait for that thread to go idle (though I doubt it would have mattered much).
