It consists of blobs with data needed for respective color HW blocks. Currently defining below blobs pre-csc: can be used to linearize the input frame buffer data. csc: used for color space conversion. post-csc: can be used non-linearize frame buffer data or to perform Tone mapping for HDR use-cases private: can be used for vendor specific fixed function operations This can be extended to include other color operations as well.
