STRUCT RKISP1_CIF_ISP_BLS_FIXED_VAL(9)

💅 struct rkisp1_cif_isp_bls_fixed_val(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes, that Kernel API Manual — and today's main character is a little struct called struct rkisp1_cif_isp_bls_fixed_val. it's giving "small but important" and honestly? we're obsessed. 🎀

---

✨ NAME ✨

struct rkisp1_cif_isp_bls_fixed_val — BLS fixed subtraction values 🫶

---

🌸 SYNOPSIS 🌸

ok so here's the whole vibe, literally the entire struct, no cap:

struct rkisp1_cif_isp_bls_fixed_val {
    __s16 r;
    __s16 gr;
    __s16 gb;
    __s16 b;
 };

four __s16 fields. that's it. that's the girl. 💅

---

🦋 MEMBERS 🦋

• r — the fixed (signed!) subtraction value for Bayer pattern R 👑
• gr — the fixed (signed!) subtraction value for Bayer pattern Gr 🌸
• gb — the fixed (signed!) subtraction value for Bayer pattern Gb ⭐
• b — the fixed (signed!) subtraction value for Bayer pattern B 💜

like, yes, we said signed four times and yes we're saying it in bold and pink because it MATTERS, iykyk. 🙈

---

💖 DESCRIPTION 💖

okay so the entire personality of this struct: the values will be subtracted from the sensor values. that's the whole bit. that's what she does. ✨

and here's the twist — a negative value means addition instead of subtraction! 😭 like not me discovering that the subtraction values can un-subtract. it's giving "math is fake but the vibes are real". so if you're sitting there like "why is my signal going up when the field is called subtraction" — bestie that's literally the documented behavior, fr fr. 💀

🫶 gentle reminder: signed fields, subtraction direction flips on negatives. no cap, don't forget it.

anyway bestie, this page came straight out of ./include/uapi/linux and it's stamped October 2026 — so mark your calendar, screenshot this, send it to the group chat, and remember: signed values, subtraction, and negative means addition. periodt. 👑🌈💖
