2020-09-29ipa: raspberrypi: Rename the controller namespace from Rpi to RpiControllerNaushir Patuck
This avoids a namespace clash with the RPi namespace used by the ipa and pipeline handlers, and cleans up the syntax slightly. There are no functional changes in this commit.

2020-09-29libcamera: ipa: raspberrypi: ALSC: Handle user transformDavid Plowman
Update ALSC (Auto Lens Shading Correction) to handle correctly the user transform now passed in the camera mode. The user transform is applied directly in the sensor so the image statistics already incorporate it, and the adaptive algorithm is entirely agnostic towards it, so all we have to do is flip the calibrated tables to match. (These tables will have been calibrated without the user transform.)

The standard way in C++17 to specify that a function or function argument may be unused it to specify the [[maybe_unused]] attribute. Replace manual void casts to silence compiler warnings.

2020-08-05libcamera: ipa: raspberrypi: ALSC: Improve behaviour when camera mode changesDavid Plowman
Now that we stop the asynchronous thread on a SwitchMode, we would do better to regenerate all the tables if the new camera mode crops in a significantly different way to the old one. A few minor tweaks make sense along with this: * Reset the lambda values when we reset everything. It wouldn't make sense to re-start with the old mode's values. * Use the last recorded colour temperature to generate new tables rather than any default value. * Set the frame "phase" counter to ensure the adaptive procedure will run asap.

2020-08-05libcamera: ipa: raspberrypi: ALSC: Resample luminance tableDavid Plowman
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). As a by-product of stopping the thread, it no longer needs its own copy of the camera mode (async_camera_mode_).

Fix up a few locations where we call notify_one() with the lock held. In particular, restartAsync does not need to be called with the lock held for its entire duration.

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.
