STRUCT RKISP1_CIF_ISP_WDR_TONE_CURVE(9)

💅 NAME 💅

struct rkisp1_cif_isp_wdr_tone_curve — the tone mapping curve definition for WDR, bestie! (This is a page from the Kernel API Manual, okurrr.)

✨ SYNOPSIS ✨

struct rkisp1_cif_isp_wdr_tone_curve {
    __u32 dY[RKISP1_CIF_ISP_WDR_CURVE_NUM_DY_REGS];
    __u16 ym[RKISP1_CIF_ISP_WDR_CURVE_NUM_COEFF];
};

🎀 Members 🎀

• dY — okay so this is the dYn increments for the horizontal (input) axis of the tone curve 👑 and listen: each 3-bit dY value represents an increment of 2**(value+3). So like, dY[0] bits 0:2 is increment dY1, bit 3 unused; dY[0] bits 4:6 is increment dY2, bit 7 unused ... dY[0] bits 28:30 is increment dY8, bit 31 unused ... and so on till dY[3] bits 28:30 is increment dY32, bit 31 unused. Periodt. 💅
• ym — the Ym values for the vertical (output) axis of the tone curve, and each value is 13 bit. Slay. ✨

Okay bestie, that's the whole page 💜 this one came out of ./include/uapi/linux, dated October 2026, and it's the struct rkisp...r_tone_curve(9) page signing off — go touch some grass, then go read your kernel headers 🫶🌸
