STRUCT RKISP1_CIF_ISP_AWB_MEAS_CONFIG(9)

💅 NAME 💅

struct rkisp1_cif_isp_awb_meas_config — bestie, this is the Configuration for the AWB statistics. that's it, that's the vibe ✨

(also hi, you're reading the Kernel API Manual, and yes the page header is literally truncated to struct rkis..._meas_config(9) — we don't know her full name either, she's mysterious like that 🎀)

✨ SYNOPSIS ✨

okay so here's the whole struct, look at her, she's iconic 👑

struct rkisp1_cif_isp_awb_meas_config {
    struct rkisp1_cif_isp_window awb_wnd;
    __u32 awb_mode;
    __u8 max_y;
    __u8 min_y;
    __u8 max_csum;
    __u8 min_c;
    __u8 frames;
    __u8 awb_ref_cr;
    __u8 awb_ref_cb;
    __u8 enable_ymax_cmp;
};

🦋 Members 🦋

time to meet the whole squad, one field at a time 🫶

• awb_wnd — the white balance measurement window, measured in pixels. that's the little box where she's allowed to look 👀
• awb_mode — the awb meas mode, fr. it comes from enum rkisp1_cif_isp_awb_mode_type. pick your fighter 💅
• max_y — only pixel values < max_y contribute to the awb measurement. set it to 0 and this whole feature is disabled, like she's off duty 😴
• min_y — only pixel values > min_y contribute to the awb measurement. gatekeeping, but make it statistics ✨
• max_csum — Chrominance sum maximum value. only consider pixels with Cb+Cr smaller than this threshold for awb measurements. it's giving "you must be this short to ride" 🎢
• min_c — Chrominance minimum value. only consider pixels with Cb/Cr each greater than this threshold value for awb measurements. lowkey the opposite vibe of max_csum 🌸
• frames — number of frames minus 1 used for the mean value calculation. ucFrames=0 means 1 Frame, no cap. math girlies stay winning 🔥
• awb_ref_cr — reference Cr value for AWB regulation, aka the target for AWB 🎯
• awb_ref_cb — reference Cb value for AWB regulation, also a target for AWB 🎯
• enable_ymax_cmp — enable Y_MAX compare. > heads up bestie: this is Not valid in RGB measurement mode. 💀 so don't come for her if it ghosts you in RGB

that's the whole page bestie, you ate that 🍓 and before you close the tab: this masterpiece lives in ./include/uapi/linux, dated October 2026, and the footer still calls her struct rkis..._meas_config(9) 😭 she's shy. periodt. 💜
