STRUCT DPU_HW_SCALER3_DE_CFG(9)

✨ NAME ✨

struct dpu_hw_scaler3_de_cfg — the QSEEDv3 detail enhancer configuration, aka the struct that tells your display's detail enhancer how to behave 💅

This page lives in the Kernel API Manual (section 9), bestie, so buckle up.

🌸 SYNOPSIS 🌸

struct dpu_hw_scaler3_de_cfg {
    u32 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];
 };

That's the whole squad right there — nothing renamed, nothing dropped, every field exactly as it appears 🫶

🎀 Members 🎀

• enable — turns the detail enhancer on and off. the vibe check switch, basically ✨
• sharpen_level1 — how hard you wanna sharpen the noise. yes, noise has its own knob 😭
• sharpen_level2 — how hard you wanna sharpen the signal. different knob, different energy 🔥
• clip — clip shift
• limit — limit value
• thr_quiet — quiet threshold
• thr_dieout — dieout threshold
• thr_high — low threshold
• thr_high — high threshold

ok we need to talk about it: the manpage literally lists thr_high twice, once for the low threshold and once for the high threshold. not me editing the source material though 🙈 we keep it exactly as written — thr_low is also in the struct, iykyk. no cap, that's what the doc says, and that's what you're getting 👑

• prec_shift — precision shift
• adjust_a — the A-coefficients for the mapping curve
• adjust_b — the B-coefficients for the mapping curve
• adjust_c — the C-coefficients for the mapping curve

(lowkey the mapping curve is having a whole main character moment with three coefficient arrays, and honestly? slay 💜)
