STRUCT RKISP1_CIF_ISP_DPCC_METHODS_CONFIG(9)

💅 struct rkisp1_cif_isp_dpcc_methods_config(9) — the Kernel API Manual, but make it make sense 🎀

okay so bestie, welcome to the Kernel API Manual ✨ today we're decoding struct rkisp1_cif_isp_dpcc_methods_config, which is genuinely just the DPCC methods set configuration and honestly? it's giving "small struct, big job" energy 💖

---

🌸 NAME 🌸

struct rkisp1_cif_isp_dpcc_methods_config — the DPCC methods set configuration, no cap 🫶

---

✨ SYNOPSIS ✨

here's the whole vibe, copied exactly so you can trust me:

struct rkisp1_cif_isp_dpcc_methods_config {
    __u32 method;
    __u32 line_thresh;
    __u32 line_mad_fac;
    __u32 pg_fac;
    __u32 rnd_thresh;
    __u32 rg_fac;
 };

(also yes there's a struct rkisp1_cif_isp_dpcc_methods_config in the original header of the page too, that's just the title doing its thing 💫)

🧚 Members 🧚

one bullet per field, let's go 🔥

• method — the method enable bits, and they're the RKISP1_CIF_ISP_DPCC_METHODS_SET_* ones 👑
• line_thresh — line threshold time, aka RKISP1_CIF_ISP_DPCC_LINE_THRESH_* 🌸
• line_mad_fac — the Line Mean Absolute Difference factor, spelled out like the icon it is (RKISP1_CIF_ISP_DPCC_LINE_MAD_FAC_*) 📐
• pg_fac — peak gradient factor bestie (RKISP1_CIF_ISP_DPCC_PG_FAC_*) 🔥
• rnd_thresh — Rank Neighbor Difference threshold, yes the whole name, RKISP1_CIF_ISP_DPCC_RND_THRESH_* 💜
• rg_fac — rank gradient factor, RKISP1_CIF_ISP_DPCC_RG_FAC_* ⭐

---

💖 Description 💖

so what is this struct even for? it stores the configuration of one set of methods for the DPCC algorithm 🦋 that's it, that's the whole assignment.

and here's the part that actually matters: you can select multiple methods in each set — and they're picked independently for the Green and Red/Blue components — all through the method field 🙈 the result is the logical AND of all enabled methods. like, every enabled one has to agree. very "we're all in this together" of them 💅

the remaining fields? they set the thresholds and factors for each method. cute, functional, done 🌈
