[v3,00/35] ipa: libipa: Introduce libipa algorithms

27200 mbox series

This series introduces the first algorithms in libipa: Awb, Lsc and Ccm.

As most of the implementations of the common algorithms derive from
RkISP1 it wasn't possible to separate the algorithm introduction with
the RkISP1 IPA modifications to maintain bisectability.

This series contains:

- Awb (Grey and Bayes)
 - RkISP1
 - Simple
 - Mali-C55

- Ccm
 - RkISP1
 - Simple
 - Mali-C55

- Lsc (grid and polynomial)
 - RkISP1
 - Mali-C55

Tested on RkISP1 with imx219 (Grey world awb and grid-based LSC) and on
Mali-C55 with imx708 (Bayes AWB and grid-based LSC).

More test on Simple and with polynomial LSC would be helpful :)

Changes in v3:
- Address comments on Awb from Stefan:
  - Introduce AwbImplementation::Result
  - Move AwbStats implementation to IPAs
  - Drop AwbStats::rg()/bg() and re-implement AwbGray accordingly
- Fix Saturation bug in Simple Ccm algorithm
- Fix Simple Ccm gain limits using Q<2, 8>
- Update Mali CCM and Gamma to latest uAPI patch version
- Fix Mali CCM gain masking as reported by Dan
- Break down libIPA Lsc implementation as requested by Stefan

Changes in v2:
- Introduce awb::Context to simplify ActiveState and FrameContext
  definition
- Add mali uAPI header for CCM and Gamma
- Do not rename Mali functions for hardware configuration in awb and lsc
- Spelling and documentation
