2021-08-12ipa: ipu3: Tidy-up includesJacopo Mondi
Tidy-up a bit the inclusions directive in the IPU3 IPA module. In detail: - ipu3.cpp is missing inclusions for: std::abs from <cmath> std::map from <map> std::min/max from <algorithm> std::numeric_limits from <limits> std::unique_ptr from <memory> std::vector from <vector> and does not require <sys/mman.h> - ipu3_agc has two not used inclusions in the header file and one the cpp file and is missing <chrono> for std::literals::chrono_literals - ipu3_awb is missing <algorithm> for std::sort and does not use <numeric> or <unordered_map> Signed-off-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com>
2021-06-28ipa: ipu3: Initialize CameraSensorHelper at IPU3 init stageJean-Michel Hautbois
In order for the CameraSensorHelper to be instantiated, we need to find its factory using the camera sensor model name stored in IPASettings::sensorModel. As we don't need to do it at each configure call (the sensor is not changing in-between), implement the init call in IPAIPU3 to do that.

2021-06-25libcamera/base: Move extended base functionalityKieran Bingham
Move the functionality for the following components to the new base support library: - BoundMethod - EventDispatcher - EventDispatcherPoll - Log - Message - Object - Signal - Semaphore - Thread - Timer While it would be preferable to see these split to move one component per commit, these components are all interdependent upon each other, which leaves us with one big change performing the move for all of them.

2021-06-24ipa: ipu3: Use libcamera::utils::Duration helper class for durationsUmang Jain
std::chrono::Duration is provided quite conveniently by libcamera::utils::Duration wrapper. Port IPAIPU3 to use that for duration-type entities (such as exposure time), such that it becomes consistent with rest of the codebase. The commit doesn't introduce any functional changes.

2021-06-08ipa: ipu3: Calculate line duration from IPACameraSensorInfoUmang Jain
Squash \todo by calculating line duration from IPACameraSensorInfo, now passed in, to IPU3Agc::initialise(). Since line duration is now calculated from real values, store it as a private member in IPU3Agc class. As a further step, replace the associated global constant, kMaxExposureTime, with a private IPU3Agc class member as well, and assign its value correspondingly in IPU3Agc::initialise(), similar to previous precedence.

2021-04-22ipa: ipu3: Add support for IPU3 AEC/AGC algorithmJean-Michel Hautbois
Implement basic auto-exposure (AE) and auto-gain (AG) correction functions. The functions computeTargetExposure() and computeGain() are adapted from the Raspberry Pi AGC implementation to suit the IPU3 structures, and filtering is added to reduce visible stepsize when there are large exposure changes.
