2023-10-18ipa: rpi: Add IpaBase::platformStart() member functionNaushir Patuck
Add a virtual IpaBase::platformStart() member function that is called at the end of IpaBase::start(). For the IpaVc4 derived class, this function does nothing, but will be used in the PiSP derived class to reset internal state on startup.

2023-10-05ipa: rpi: Avoid skipping IPAs on the first frame after the drop framesDavid Plowman
We avoid skipping the IPAs while frameCount_ is less than dropFrameCount_, indicating that these frames will not be sent to the application. This means that when these numbers are equal then this is the first frame the application will get, so again, we must avoid skipping the IPAs. Consequently the test here must avoid the case of equality.

2023-09-25pipeline: rpi: Reset the frame lengths queue during configureNaushir Patuck
The IPA stores a list of the last 10 frame lengths applied to the sensor for determining the timeout to use. This list gets reset on start(), but there is a path through the code that accesses this list in configure() which happens earlier, causing a logical error. Fix this by constructing the list with 10 initial values of 0s.

2023-09-25ipa: rpi: Fix frame count logic when running algorithmsNaushir Patuck
The frame counter test to determine if we run the IPA algorithms has a logic bug where it treats dropFrameCount_ and mistrustCount_ as frame numbers, not counts of frames (which it is). The implication is that startup convergence and initial settings take one extra frame to apply. Fix this.

2023-09-16ipa: rpi: agc: Reorganise code for multi-channel AGCDavid Plowman
This commit does the basic reorganisation of the code in order to implement multi-channel AGC. The main changes are: * The previous Agc class (in agc.cpp) has become the AgcChannel class in (agc_channel.cpp). * A new Agc class is introduced which is a wrapper round a number of AgcChannels. * The basic plumbing from ipa_base.cpp to Agc is updated to include a channel number. All the existing controls are hardwired to talk directly to channel 0. There are a couple of limitations which we expect to apply to multi-channel AGC. We're not allowing different frame durations to be applied to the channels, nor are we allowing separate metering modes. To be fair, supporting these things is not impossible, but there are reasons why it may be tricky so they remain "TBD" for now. This patch only includes the basic reorganisation and plumbing. It does not yet update the important methods (switchMode, prepare and process) to implement multi-channel AGC properly. This will appear in a subsequent commit. For now, these functions are hard-coded just to use channel 0, thereby preserving the existing behaviour.

2023-09-04ipa: rpi: agc: Split AgcStatus into AgcStatus and AgcPrepareStatusDavid Plowman
The Agc::process() function returns an AgcStatus object in the metadata as before, but Agc::prepare() is changed to return the values it computes in a separate AgcPrepareStatus object (under the new tag "agc.prepare_status"). The "digitalGain" and "locked" fields are moved from AgcStatus to AgcPrepareStatus. This will be useful going forward as we can be more flexible about the order in which prepare() and process() are called, without them trampling on each other's results.

The FocusFom metadata was no longer being reported back because the "focus.status" metadata was never being created.

The "Auto" mode, as well as reporting the detected flicker period via the "AeFlickerDetected" metadata, are unsupported for now.

Do not advertise colour related controls (i.e. [A]WB, colour saturation) in the ControlInfoMap of available controls returned out to the application. Silently ignore these controls in the control handler in case applications don't use the advertised ControlInfoMap to validate controls. As a drive-by fix, don't advertise controls::ColourCorrectionMatrix in the ControlInfoMap as it is not handled by the IPA.

2023-05-04ipa: raspberrypi: Introduce IpaBase classNaushir Patuck
Create a new IpaBase class that handles general purpose housekeeping duties for the Raspberry Pi IPA. The implementation of the new class is essentially pulled from the existing ipa/rpi/vc4/raspberrypi.cpp file with a minimal amount of refactoring. Create a derived IpaVc4 class from IpaBase that handles the VC4 pipeline specific tasks of the IPA. Again, code for this class implementation is taken from the existing ipa/rpi/vc4/raspberrypi.cpp with a minimal amount of refactoring. The goal of this change is to allow third parties to implement their own IPA running on the Raspberry Pi without duplicating all of the IPA housekeeping tasks.
