2022-10-01ipa: rkisp1: Remove initialized_ flags from algorithmsLaurent Pinchart
Multiple algorithms have an initialized_ flag that they set to true at the end of the init() function, and check at the beginning of prepare() to skip preparation. This serves no real purpose, as the flag can only be false if init() fails, in which case the IPA module initialization as a whole will fail. Drop the initialized_ flags.

2022-09-28ipa: rkisp1: awb: Remove bias from gain calculationLaurent Pinchart
The red and blue gains are computed by dividing the green mean by the red and blue means respectively. An offset of 1 is added to the dividers to avoid divisions by zero. This introduces a bias in the gain values. Fix it by clamping the divisors to a minimum of 1.0 instead of adding an offset.

2022-09-28ipa: rkisp1: awb: Clamp gains to prevent divisions by zeroLaurent Pinchart
The gain values are currently clamped to the range [0.0, 3.996] used by the hardware. A zero value makes little sense, as it would completely remove the contribution of the corresponding color channel from the AWB accumulators, but worse, would lead to divisions by zero when calculating the raw means in subsequent iterations. Prevent this by setting the minimum gain value to 1/256. While at it, clamp the gain values before filtering them, to improve the stability of the control loop.

2022-09-28ipa: rkisp1: awb: Add support for RGB meansQuentin Schulz
RkISP actually supports two modes for color means, RGB and YCbCr. The variables where the means are stored are identically named regardless of the color means mode that's been selected. Since the gains are computed in RGB mode, a conversion needs to be done when the mode is YCbCr, which is unnecessary when RGB mode is selected. This adds support for RGB means mode too, by checking at runtime which mode is selected at a given time. The default is still set to YCbCr mode for now.

The AWB statistics are computed after the ISP applies the colour gains. This means that the red, green and blue means do not match the data coming directly from the sensor, but are multiplied by the colour gains that were used for the frame on which the statistics have been computed. The AWB algorithm needs to take this into account when calculating the colour gains for the next frame. Do so by dividing the means by the gains that were applied to the frame, retrieved from the frame context.

2022-09-28ipa: rkisp1: awb: Store per-frame information in frame contextLaurent Pinchart
Rework the algorithm's usage of the active state and frame context to store data in the right place. The active state stores two distinct categories of information: - The consolidated value of all algorithm controls. Requests passed to the queueRequest() function store values for controls that the application wants to modify for that particular frame, and the queueRequest() function updates the active state with those values. The active state thus contains a consolidated view of the value of all controls handled by the algorithm. - The value of parameters computed by the algorithm when running in auto mode. Algorithms running in auto mode compute new parameters every time statistics buffers are received (either synchronously, or possibly in a background thread). The latest computed value of those parameters is stored in the active state in the process() function. The frame context also stores two categories of information: - The value of the controls to be applied to the frame. These values are typically set in the queueRequest() function, from the consolidated control values stored in the active state. The frame context thus stores values for all controls related to the algorithm, not limited to the controls specified in the corresponding request, but consolidated from all requests that have been queued so far. For controls that can be specified manually or computed by the algorithm depending on the operation mode (such as the colour gains), the control value will be stored in the frame context in queueRequest() only when operating in manual mode. When operating in auto mode, the values are computed by the algorithm and stored in the frame context in prepare(), just before being stored in the ISP parameters buffer. The queueRequest() function can also store ancillary data in the frame context, such as flags to indicate if (and what) control values have changed compared to the previous request. - Status information computed by the algorithm for a frame. For instance, the colour temperature estimated by the algorithm from ISP statistics calculated on a frame is stored in the frame context for that frame in the process() function. The active state and frame context thus both contain identical members for most control values, but store values that have a different meaning.

2022-09-28ipa: rkisp1: Rename frameContext to activeStateKieran Bingham
The RkISP1 IPA module creates a single instance of its IPAFrameContext structure, effectively using it more as an active state than a per-frame context. To prepare for the introduction of a real per-frame context, move all the members of the IPAFrameContext structure to a new IPAActiveState structure. The IPAFrameContext becomes effectively unused at runtime, and will be populated back with per-frame data after converting the RkISP1 IPA module to using a frame context queue. The IPAActiveState structure will slowly morph into a different entity as individual algorithm get later ported to the frame context API.

2022-06-29ipa: libipa: Introduce a Module class templateLaurent Pinchart
libipa defines an abstract Algorithm class template that is specialized by IPA modules. IPA modules then instantiate and manage algorithms internally, without help from libipa. With ongoing work on tuning data support for the RkISP1, and future similar work for the IPU3, more code duplication for algorithms management is expected. To address this and share code between multiple IPA modules, introduce a new Module class template that will define and manage top-level concepts for the IPA module. The Module class template needs to be specialized with the same types as the Algorithm class. To avoid manual specialization of both classes, store the types in the Module class, and replace the template arguments of the Algorithm class with a single Module argument from which the other types are retrieved.

2022-06-01libcamera: Use "..." instead of <...> consistently for internal headersLaurent Pinchart
libcamera uses double quotes for #include directives for internal headers. A few <...> have found their way in the code base over time. Fix them. While at it, move an Android header include to the right location.

2022-05-18ipa: libipa: Add frame context pointer in process()Umang Jain
Currently we have a single structure of IPAFrameContext but subsequently, we shall have a ring buffer (or similar) container to keep IPAFrameContext structures for each frame. It would be a hassle to query out the frame context required for process() (since they will reside in a ring buffer) by the IPA for each process. Hence, prepare the process() libipa template to accept a particular IPAFrameContext early on. As for this patch, we shall pass in the pointer as nullptr, so that the changes compile and keep working as-is.
