2024-01-09ipa: vc4: Implement the StatsOutputEnable vendor controlNaushir Patuck
Implement the StatsOutputEnable control for the VC4 IPA. When set, this outputs the ISP statistics as a uint8_t span through the Bcm2835StatsOutput metadata control. To get this working, IpaBase::libcameraMetadata_ is moved from a private to a protected member variable. This makes it accessable to the VC4 derived IPA class.

2023-11-30libcamera: controls: Use vendor tags for draft controls and propertiesNaushir Patuck
Label draft controls and properties through the "draft" vendor tag and deprecate the existing "draft: true" mechanism. This uses the new vendor tags mechanism to place draft controls in the same libcamera::controls::draft namespace and provide a defined control id range for these controls. This requires moving all draft controls from control_ids.yaml to control_ids_draft.yaml. One breaking change in this commit is that draft control ids also move to the libcamera::controls::draft namespace from the existing libcamera::controls namespace. This is desirable to avoid API breakages when adding new libcamera controls. So, for example, the use of controls::NOISE_REDUCTION_MODE will need to be replaced with controls::draft::NOISE_REDUCTION_MODE.

2023-10-24ipa: rpi: vc4: Move denoise control handling into the VC4 derived IPANaushir Patuck
Since noise control handling differs between the VC4 and PiSP IPAs, move the current denoise control handler from ipa base into the vc4 IPA derived class.

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.

2023-09-04ipa: rpi: vc4: Make the StatisticsPtr construction clearerDavid Plowman
StatisticsPtr is a shared pointer, so the use of std::make_unique to create it was a bit confusing. Use std::make_shared instead.

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.

2023-05-04pipeline: raspberrypi: Introduce PipelineHandlerBase classNaushir Patuck
Create a new PipelineHandlerBase class that handles general purpose housekeeping duties for the Raspberry Pi pipeline handler. Code the implementation of new class is essentially pulled from the existing pipeline/rpi/vc4/raspberrypi.cpp file with a small amount of refactoring. Create a derived PipelineHandlerVc4 class from PipelineHandlerBase that handles the VC4 pipeline specific tasks of the pipeline handler. Again, code for this class implementation is taken from the existing pipeline/rpi/vc4/raspberrypi.cpp with a small amount of refactoring. The goal of this change is to allow third parties to implement their own pipeline handlers running on the Raspberry Pi without duplicating all of the pipeline handler housekeeping tasks.
