ipa: rkisp1: Initialize FrameContext.agc.meteringModepfc/rkisp1-free-run
The RkISP1 AGC algorithms assumes the metering mode to be "MeteringMatrix" and pre-fill an array of weights associated with it stored in meteringModes_[MeteringMatrix] when intializing the algorithm in parseMeteringModes(). It laters fetches the weights when computing parameters using the FrameContext.agc.meteringMode as index of the meteringModes_ array. When a Request gets queued to the algorithm, the FrameContext.agc.meteringMode index is populated from the algorithm's active state, and optionally updated if the application has specified a different metering mode. In case of Request underrun however, a non-initialized FrameContext gets provided to the algorithm, causing an (unhandled) exception when accessing the meteringModes_ array. Fix this by intializing the AGC metering mode to a supported value coming from the ActiveState in IPAFrameContext::init(). Signed-off-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com>
