From 906373331f1bc1a0411a48ef5ae3d1d54c19122c Mon Sep 17 00:00:00 2001 From: Kieran Bingham Date: Thu, 21 Jul 2022 13:13:03 +0100 Subject: ipa: rkisp1: Rename frameContext to activeState 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. While at it, fix a typo in the documentation of the Agc::computeExposure() function that incorrectly refers to the frame context instead of the global context.
