STRUCT DPU_DRM_DE_V1(9)

💖 struct dpu_drm_de_v1(9) — the glow-up page

okay so bestie, welcome to the Kernel API Manual, section 9, and today's main character is struct dpu_drm_de_v1 — literally version 1 of the detail enhancer structure ✨ ngl it's giving "glow-up settings but make it silicon."

---

🌸 NAME 🌸

struct dpu_drm_de_v1 — version 1 of detail enhancer structure. that's it, that's the whole vibe 💅

---

🎀 SYNOPSIS 🎀

here's the whole struct, copied exactly, no cap, character for character:

struct dpu_drm_de_v1 {
    uint32_t enable;
    int16_t sharpen_level1;
    int16_t sharpen_level2;
    uint16_t clip;
    uint16_t limit;
    uint16_t thr_quiet;
    uint16_t thr_dieout;
    uint16_t thr_low;
    uint16_t thr_high;
    uint16_t prec_shift;
    int16_t adjust_a[DPU_MAX_DE_CURVES];
    int16_t adjust_b[DPU_MAX_DE_CURVES];
    int16_t adjust_c[DPU_MAX_DE_CURVES];
 };

look at her. iconic. every field has a job and every job has a field 🫶

🦋 Members 🦋

okay field-by-field, let's go, keep up 💫

• enable — turns the detail enhancer on and off, your basic on/off bestie
• sharpen_level1 — the sharpening strength for noise 👀
• sharpen_level2 — the sharpening strength for context, yes there are two, no they are not the same
• clip — the clip coefficient
• limit — the detail enhancer limit factor
• thr_quiet — the quite zone threshold (that's how it's spelled in the original, keeping it 💀)
• thr_dieout — the die-out zone threshold
• thr_low — the linear zone left threshold
• thr_high — the linear zone right threshold
• prec_shift — the detail enhancer precision
• adjust_a — mapping curves A coefficients, an array of DPU_MAX_DE_CURVES of int16_t
• adjust_b — mapping curves B coefficients, also DPU_MAX_DE_CURVES of int16_t
• adjust_c — mapping curves C coefficients, you guessed it, DPU_MAX_DE_CURVES of int16_t

the three adjust_ arrays are all int16_t[DPU_MAX_DE_CURVES] in case you were wondering — A, B, and C, all accounted for, all slaying 🌈
