STRUCT C3_ISP_PARAMS_BLC(9)

✨ struct c3_isp_params_blc(9) ✨

okay so this is a page from the Kernel API Manual, section 9 — and bestie, it's literally all about the ISP Black Level Correction config 💅

---

🌸 NAME 🌸

struct c3_isp_params_blc — the ISP Black Level Correction configuration, no cap 🎀

---

🦋 SYNOPSIS 🦋

struct c3_isp_params_blc {
    struct c3_isp_params_block_header header;
    __u16 gr_ofst;
    __u16 r_ofst;
    __u16 b_ofst;
    __u16 gb_ofst;
 };

like, that's the whole vibe right there ✨

---

💖 Members 💖

• header — the C3 ISP parameters block header, the main character that has to be there 🫶
• gr_ofst — Gr blc offset, in Q4.12 format 👑
• r_ofst — R blc offset, also in Q4.12 format ⭐
• b_ofst — B blc offset, yep, Q4.12 format 🌈
• gb_ofst — Gb blc offset, Q4.12 format (notice the original literally writes it as offset(Q4.12 format) with no space before the paren — she's quirky like that 🙈)

---

🌟 Description 🌟

This struct is what lets you configure the block level offset for each color channel — one offset per channel, all four accounted for 💅

And here's the part you cannot skip, fr fr: header.type should be set to C3_ISP_PARAMS_BLOCK_BLC from :c:type:c3_isp_params_block_type``. That's the vibe check for this block — set it or the whole thing is giving wrong-block energy 💀

quick heads up bestie: the source path at the bottom gets cut off in the original as ./include/uapi/linux/media/aml... — that's genuinely how it's printed, so don't come for me 🙈

and that's the page! sourced from ./include/uapi/linux/media/aml... and dated October 2026 — literally from the future, periodt 👑💜
