STRUCT IPU3_UAPI_BNR_STATIC_CONFIG_WB_GAINS_CONFIG(9)

💅 struct ipu3_uapi_bnr_static_config_wb_gains_config(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this lil page is all about struct ipu3_uapi_bnr_static_config_wb_gains_config, and honestly? It's giving "tiny struct, big white-balance energy" 💖

---

✨ NAME ✨

struct ipu3_uapi_bnr_static_config_wb_gains_config — White balance gains 🎀

---

🦋 SYNOPSIS 🦋

struct ipu3_uapi_bnr_static_config_wb_gains_config {
    __u16 gr;
    __u16 r;
    __u16 b;
    __u16 gb;
 };

yes bestie, that's the whole struct in all its four-field glory — copy it exactly, no cap 💅

---

🌸 Members 🌸

• gr — the white balance gain for the Gr channel 🟢
• r — the white balance gain for the R channel 🔴
• b — the white balance gain for the B channel 🔵
• gb — the white balance gain for the Gb channel 🟩

---

💜 Description 💜

So for the BNR parameters, this is the WB gain factor for the three channels — and the page lists them as [Ggr, Ggb, Gb, Gr] 👑

Their precision is U3.13, and the range is (0, 8), and the actual gain is Gx + 1. Typically it's Gx = 1 ✨

And the formula, iconic as always:

Pout = {Pin * (1 + Gx)};

that's it, that's the math, and it ate 💅🔥
