STRUCT IPU3_UAPI_BNR_STATIC_CONFIG_GREEN_DISPARITY(9)

💖 struct ipu3_uapi_bnr_static_config_green_disparity(9) 💖

okay so this is from the kernel API manual (section 9, the driver-API girlies), and honestly? she's a whole vibe. sit down bestie, we're talking about green disparity correction ✨

---

🌸 NAME 🌸

struct ipu3_uapi_bnr_static_config_green_disparity — correct green disparity, no cap 🫶

---

🎀 SYNOPSIS 🎀

like, literally the exact struct, mkay, don't touch a single bit:

struct ipu3_uapi_bnr_static_config_green_disparity {
    __u32 gd_red:6;
    __u32 reserved0:2;
    __u32 gd_green:6;
    __u32 reserved1:2;
    __u32 gd_blue:6;
    __u32 reserved2:10;
    __u32 gd_black:14;
    __u32 reserved3:2;
    __u32 gd_shading:7;
    __u32 reserved4:1;
    __u32 gd_support:2;
    __u32 reserved5:1;
    __u32 gd_clip:1;
    __u32 gd_central_weight:4;
 };

🦋 Members 🦋

bestie, meet the members. every single bit-field, every single default, i'm not skipping a crumb 🍓

• gd_red — the shading gain coeff for gr disparity level in bright red region. precision u0.6, default 4 (0.0625). she's precise 💅
• reserved0 — reserved. iconic, mysterious, does nothing. we respect her 🎀
• gd_green — shading gain coeff for gr disparity level in bright green region. precision u0.6, default 4 (0.0625).
• reserved1 — reserved. again. leave her alone 😌
• gd_blue — shading gain coeff for gr disparity level in bright blue region. precision u0.6, default 4 (0.0625).
• reserved2 — reserved, reserved-ing, as she should 💀
• gd_black — maximal green disparity level in dark region (and like, anything with a stronger disparity is assumed to be image detail, iykyk). precision u14, default 80.
• reserved3 — reserved 🫶
• gd_shading — changes the maximal green disparity level according to square distance from image center. main character energy, honestly 🦋
• reserved4 — reserved ✨
• gd_support — lower bound for the number of second green color pixels in the current pixel neighborhood with less than threshold difference from it. whole lotta words, but she ate 🍽️
• reserved5 — reserved 🙈
• gd_clip — turns green disparity clip on/off, [0, 1], default 1. she's a literal on/off switch, slay.
• gd_central_weight — central pixel weight in 9 pixels weighted sum. yes, nine. not eight, not ten. 9 🔥

🌈 Description 🌈

so the shading gain coeff of red, green, blue and black? they're all used to calculate the threshold given a pixel's color value and its coordinates in the image. that's the whole ~situation~, and it's giving very much "math but make it fashion" 👑

bestie reminder: reserved0 through reserved5 are, like, actually reserved. do not touch. do not write vibes into them. that's a warning, not a suggestion 💀
