STRUCT OMAP3ISP_CCDC_LSC_CONFIG(9)

💖 struct omap3isp_ccdc_lsc_config(9) 💖

okay so this is a page from the Kernel API Manual and bestie, we're about to get so cozy with the LSC config struct. it's giving "niche kernel header" and honestly? iconic. let's go 🫶

---

✨ NAME ✨

struct omap3isp_ccdc_lsc_config — the LSC configuration, fr fr 💅

---

🌸 SYNOPSIS 🌸

struct omap3isp_ccdc_lsc_config {
    __u16 offset;
    __u8 gain_mode_n;
    __u8 gain_mode_m;
    __u8 gain_format;
    __u16 fmtsph;
    __u16 fmtlnh;
    __u16 fmtslv;
    __u16 fmtlnv;
    __u8 initial_x;
    __u8 initial_y;
    __u32 size;
 };

look at her. eleven fields, all accounted for, not one of them skipped. we love a complete struct 😭💖

🦋 Members 🦋

here's the whole cast, member by member — no cap, every single one:

• offset — the table offset of the gain table. where it sits, basically 💫
• gain_mode_n — the vertical dimension of a paxel in the LSC configuration. vertical, bestie. n = north energy 📐
• gain_mode_m — the horizontal dimension of a paxel in the LSC configuration. horizontal, matching set with gain_mode_n 🎀
• gain_format — the gain table format. that's the vibe check for your table 💅
• fmtsph — start pixel horizontal, measured from the start of the HS sync pulse 🌈
• fmtlnh — the number of pixels in the horizontal direction to use for the data reformatter ✨
• fmtslv — start line from the start of the VS sync pulse, for the data reformatter 🦋
• fmtlnv — the number of lines in the vertical direction for the data reformatter 🌸
• initial_x — the X position, in pixels, of the first active pixel in reference to the first active paxel. must be an even number 👀 (yes, that's a real requirement, don't come for me)
• initial_y — the Y position, in pixels, of the first active pixel in reference to the first active paxel. must be an even number too 🙈 (even. numbers. only. periodt)
• size — the size of the LSC gain table. it gets filled in when loaded from userspace, so it's a "trust the process" kind of field 💜

lowkey important: initial_x and initial_y both must be an even number. that's not a suggestion, that's the spec 🥲

and that's the page, bestie 🎀 sign-off time: this one lives in ./include/uapi/linux, and it's dated October 2026 — so you know it's fresh. go forth and configure your LSC gain table responsibly. mwah 💋✨👑
