STRUCT IPU3_UAPI_OBGRID_PARAM(9)

💖 struct ipu3_uapi_obgrid_param(9) 💖

okay so bestie, welcome to the <pink>struct ipu3...obgrid_param(9)</pink> page from the Kernel API Manual — this is the lil struct that holds your Optical black level compensation parameters and honestly? she's small but she's doing important work. 🎀

---

✨ NAME ✨

struct ipu3_uapi_obgrid_param — Optical black level compensation parameters 🌸

---

🦋 SYNOPSIS 🦋

struct ipu3_uapi_obgrid_param {
    __u16 gr;
    __u16 r;
    __u16 b;
    __u16 gb;
 };

like. four whole __u16s. tiny struct, big main character energy. 💅

---

👑 Members 👑

• gr — the grid table values for color GR ✨
• r — the grid table values for color R 🍓
• b — the grid table values for color B 🦋
• gb — the grid table values for color GB 🌈

four channels, four fields, one grid table each. iykyk. 🫶

---

💜 Description 💜

so here's the tea, bestie: black level is different for red, green, and blue channels. not me finding that out and needing a whole struct about it 😭 so yeah — black level compensation is different per channel. that's literally the whole point. periodt. 🔥

ngl this one's chill — no scary warnings, no undefined behaviour, just four __u16 fields being their best selves. 🌸
