STRUCT PISP_BE_LSC_CONFIG(9)

💅 struct pisp_be_lsc_config(9) — PiSP Back End LSC config

okay bestie, welcome to the Kernel API Manual page for struct pisp_be_lsc_config(9) — yes it's a mouthful, no we're not renaming it, it's iconic as is 🎀

---

✨ NAME ✨

struct pisp_be_lsc_config — the PiSP Back End LSC config 🦋

---

🌸 SYNOPSIS 🌸

struct pisp_be_lsc_config {
    __u16 grid_step_x;
    __u16 grid_step_y;
  #define PISP_BE_LSC_LUT_SIZE    (PISP_BE_LSC_GRID_SIZE + 1);
    __u32 lut_packed[PISP_BE_LSC_LUT_SIZE][PISP_BE_LSC_LUT_SIZE];
 };

like, that's the whole struct, and the #define is just sitting there in the middle of it — not me questioning it, I'm just saying 👀

---

🎀 Members 🎀

• grid_step_x — the reciprocal of the cell size width, lowkey essential fr fr 💖
• grid_step_y — reciprocal of the cell size height, the y-axis bestie to grid_step_x 🫶
• lut_packed — jointly-coded RGB gains for each LSC grid, and it's a 2D array the size of PISP_BE_LSC_LUT_SIZE by PISP_BE_LSC_LUT_SIZE, so like... a whole little table of gains 💅✨

💜 Description 💜

It's the Lens Shading Correction configuration — that's the vibe. That's literally the whole description and honestly? she said what she said 🌈

real talk tho: this page is short but the list is not, so don't come for me about length — every single reference is up there ⭐

and that's a wrap on struct pisp_be_lsc_config(9) 💖 source file's over at ./include/uapi/linux/media/ras... and the date on this whole thing is October 2026 — yes, October 2026, we're living in the future apparently 😭🦋 go slay some lens shading bestie, mwah 💅✨
