2020-06-25libcamera: ipa: raspberrypi: Make sharpening mode_factor an ordinary doubleDavid Plowman
No need for it to be std::atomic as SwitchMode runs synchronously with Prepare. Signed-off-by: David Plowman <david.plowman@raspberrypi.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-06-22libcamera: ipa: raspberrypi: Recalculate camera exposure/gain when camera ↵David Plowman
mode changes This commit causes the AGC to recalculate its camera exposure/gain values when the camera mode changes. For example it's possible that the exposure profile could be changed by the application so the division between exposure time and analogue gain may be different. The other underlying reason (and which this commit accomplishes too) is that the sensor's line timing may change in a new mode, and because V4L2 drivers store a number of exposure _lines_, the resulting _time_ will "change under our feet". So we have to go through the process of recalculating the correct number of lines and writing this back to the sensor with every mode switch, regardless of anything else.

2020-06-22libcamera: ipa: raspberrypi: Allow SwitchMode method to return camera settingsDavid Plowman
This commit adds a Metadata parameter to the SwitchMode method enabling it to return camera and other settings to the caller (usually the configure method, just after the camera mode has been selected). In future this will allow the Raspberry Pi IPAs to take those settings (such as exposure and analogue gain) and program them directly into the camera or ISP before the camera is even started.
