STRUCT RKISP1_CIF_ISP_WDR_CONFIG(9)

✨ struct rkisp1_cif_isp_wdr_config(9) ✨

okay bestie, so this is a page from the Kernel API Manual — it's all about struct rkisp1_cif_isp_wdr_config, and no cap, it's the glow-up struct for your camera's wide dynamic range setup 🦋. Stay with me, it's actually so good.

---

🌸 NAME 🌸

struct rkisp1_cif_isp_wdr_config — the config bundle for wide dynamic range, aka the thing that keeps your highlights from eating your shadows alive 💅.

---

⭐ SYNOPSIS ⭐

struct rkisp1_cif_isp_wdr_config {
    struct rkisp1_cif_isp_wdr_tone_curve tone_curve;
    struct rkisp1_cif_isp_wdr_iref_config iref_config;
    __u16 rgb_offset;
    __u16 luma_offset;
    __u16 dmin_thresh;
    __u8 dmin_strength;
    __u8 use_rgb_colorspace;
    __u8 bypass_chroma_mapping;
    __u8 use_iref;
};

like, that's the whole cast of characters. main character energy from top to bottom 👑

🎀 Members 🎀

okay so let's meet everyone in the group chat one by one:

• tone_curve — the tone mapping curve. this is the vibe-setter, it's giving "here's how we map the tones" ✨
• iref_config — illumination reference configuration. (this one only joins the party when use_iref is true 🫶)
• rgb_offset — RGB offset value for RGB operation mode. (12 bits)
• luma_offset — luminance offset value for RGB operation mode. (12 bits)
• dmin_thresh — lower threshold for deltaMin value. (12 bits)
• dmin_strength — strength factor for deltaMin. (valid range is 0x00..0x10 — don't go outside the range, bestie, it's literally not that hard 🙈)
• use_rgb_colorspace — use RGB instead of luminance/chrominance colorspace. switching it up, we love a plot twist 🌈
• bypass_chroma_mapping — disable chrominance mapping (only valid if use_rgb_colorspace = 0 — read the fine print, it's giving conditional 💀)
• use_iref — use illumination reference instead of Y for tone mapping and gain calculations. icon behavior honestly 🔥

and that's the whole page, bestie 🫶✨ this one lives at ./include/uapi/linux, dated October 2026, and yes the footer said struct rkisp...p_wdr_config(9) because even manpage footers get truncated — iconic honestly 💅🎀
