STRUCT C3_ISP_PARAMS_CSC(9)

💅 struct c3_isp_params_csc(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ this one's all about struct c3_isp_params_csc — your little glow-up kit for telling the C3 ISP how to do Color Space Conversion. no cap, it's giving "small struct, big color energy" 🌈

---

🌸 NAME 🌸

struct c3_isp_params_csc — ISP Color Space Conversion configuration 🎨💖

---

✨ SYNOPSIS ✨

like, here's the whole shape of it, literally:

struct c3_isp_params_csc {
    struct c3_isp_params_block_header header;
    __s16 matrix[3][3];
    __u16 reserved[3];
 };

---

🎀 Members 🎀

• header — the C3 ISP parameters block header 👑 it's the vibe check every block has to pass first.
• matrix — a 3x3 matrix used for the color space conversion, and bestie listen: the value of matrix[x][y] is orig_value x 256. the range is [-4096..4095] 📐✨
• reserved — applications must zero this array 🙈 fr fr, zero it. don't be out here leaving mystery bytes, that's not the move.

---

💀 Description 💀

so this struct is literally the whole point of the page 💅 it lets you configure the matrix for color space conversion. the matrix consists of 3 x 3 points, so you need to set matrix[3][3] — all nine of them, no skipping, we're not doing partial grids in this house 🫶

and don't forget the main character detail: header.type should be set to C3_ISP_PARAMS_BLOCK_CSC from :c:type:c3_isp_params_block_type`` ⭐ like, that's how anyone knows what this block even is. iykyk.

lowkey important: if you skip the header.type assignment, your block is just sitting there with no identity. not iconic. set it. 🎯
