STRUCT PISP_BE_GEQ_CONFIG(9)

🌸 struct pisp_be_geq_config — PiSP Back End GEQ config 🌸

okay so this is a page from the Kernel API Manual, and it's literally all about struct pisp_be_geq_config — PiSP Back End GEQ config, bestie. it's a lil struct, it's giving "small but mighty," and we're gonna go through every single field together, no skipping, periodt 💅

---

✨ SYNOPSIS ✨

here's the whole struct, and yes we're keeping it exactly as-is so u can copy-paste it into ur life:

struct pisp_be_geq_config {
    __u16 offset;
  #define PISP_BE_GEQ_SHARPER (1U << 15);
  #define PISP_BE_GEQ_SLOPE ((1 << 10) - 1);
    __u16 slope_sharper;
    __u16 min;
    __u16 max;
 };

like… look at it. two #defines tucked in there all casual, PISP_BE_GEQ_SHARPER set to (1U << 15) and PISP_BE_GEQ_SLOPE set to ((1 << 10) - 1). iconic, honestly. 🎀

every member, one by one, because we do NOT leave anyone out in this group chat:

• offset — the offset value, used for threshold calculation. that's its whole job and it does it well 💖
• slope_sharper — this is the slope/sharper configuration, the main character of the field list ngl
• min — the minimum value the threshold may have. it's the floor, the bare minimum, the "u must be at least this tall to ride" 🎢
• max — the maximum value the threshold may have. the ceiling. the limit. the "that's enough out of u" 🧚

🌈 Description 🌈

Green Equalisation configuration ✨ that's the whole vibe — this struct holds the config for Green Equalisation. short and sweet, and honestly? we respect the brevity.

and that's the page!! ty for coming to my TED talk, u now know everything about struct pisp_be_geq_config and honestly? u ate that 🍓💅 slay, go forth and configure ur thresholds responsibly, mwah 💖
