STRUCT RKISP1_CIF_ISP_AWB_GAIN_CONFIG(9)

💅 struct rkisp1_cif_isp_awb_gain_config(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for struct rkisp1_cif_isp_awb_gain_config, and it's literally the little config struct that auto white balance gain uses to do its thing 🎀. yes, the header up top is all squished like struct rkis..._gain_config(9) because apparently the man page generator was having a moment 😭 — it's the same struct, i promise.

---

✨ NAME ✨

struct rkisp1_cif_isp_awb_gain_config — the configuration used by auto white balance gain 🦋

---

🌸 SYNOPSIS 🌸

struct rkisp1_cif_isp_awb_gain_config {
    __u16 gain_red;
    __u16 gain_green_r;
    __u16 gain_blue;
    __u16 gain_green_b;
 };

bestie it's giving four little __u16 fields and they're all about gain 🔥

---

🎀 Members 🎀

• gain_red — the gain value for the red component, she's the red one 💅
• gain_green_r — the gain value for the green component in the red line, yes that's a real distinction, iykyk 👑
• gain_blue — the gain value for the blue component, blue crew stand up 💙
• gain_green_b — the gain value for the green component in the blue line, sibling of gain_green_r 🌈

---

🦋 Description 🦋

so here's the vibe check: all fields in this struct are 10 bit ⭐. and 0x100h = 1, it's an unsigned integer value, range 0 to 4 with an 8 bit fractional part. no cap, that's the whole scale 🧚

and the math is literally right here, bestie — do not freelance on this one:

out_data_x = ( AWB_GAIN_X * in_data + 128) >> 8

that's the glow-up formula for your data ✨

bestie this is a kernel struct page, so yeah, the SEE ALSO section is basically a whole group chat 💀 but every single one of those is exactly as written, no edits, periodt 💅

okay that's the page!! 🫶 this lil icon was brought to you from ./include/uapi/linux, dated October 2026, and she lives in the Kernel API Manual — mwah, bye bestie 😭💖
