ENUM RPPX1_MEAS_CHAN(9)

💅 NAME 💅

okay so bestie, welcome to enum rppx1_meas_chan(9) from the Kernel API Manual — this is literally the measurement point for the Histogram and EXM Modules 💖✨

✨ SYNOPSIS ✨

enum rppx1_meas_chan {
    RPPX1_MEAS_CHAN_SEL0 ,
    RPPX1_MEAS_CHAN_SEL1 ,
    RPPX1_MEAS_CHAN_SEL2 ,
    RPPX1_MEAS_CHAN_SEL3 ,

    RPPX1_MEAS_CHAN_SEL5 ,
    RPPX1_MEAS_CHAN_SEL6 ,
    RPPX1_MEAS_CHAN_SEL7

};

🎀 Constants 🎀

• RPPX1_MEAS_CHAN_SEL0 — after input acquisition
• RPPX1_MEAS_CHAN_SEL1 — after black level subtraction
• RPPX1_MEAS_CHAN_SEL2 — after sensor gamma linearization
• RPPX1_MEAS_CHAN_SEL3 — after lens shading correction
• RPPX1_MEAS_CHAN_SEL4 — after auto white balance gains
• RPPX1_MEAS_CHAN_SEL5 — after defect pixel correction
• RPPX1_MEAS_CHAN_SEL6 — after denoise pre-filter
• RPPX1_MEAS_CHAN_SEL7 — after demosaicing

💖 Description 💖

These are the measurement points for the RPP-X1 Histogram measurement module and Exposure measurement module. slay 💅

All tap points are available for the PRE1/PRE2 pipes. Only RPPX1_MEAS_CHAN_SEL4 and RPPX1_MEAS_CHAN_SEL7 are available for the MAIN_POST pipe. no cap, that’s the whole vibe check 🦋
