STRUCT IPU3_UAPI_DM_CONFIG(9)

💅 struct ipu3_uapi_dm_config(9) 💅

okay so bestie, this is a page from the Kernel API Manual and it's all about struct ipu3_uapi_dm_config — the de-mosaic parameters. yes it's giving "niche camera pipeline struct" but it's lowkey iconic, trust. 🎀

✨ NAME ✨

struct ipu3_uapi_dm_config — De-mosaic parameters 🦋

✨ SYNOPSIS ✨

struct ipu3_uapi_dm_config {
    __u32 dm_en:1;
    __u32 ch_ar_en:1;
    __u32 fcc_en:1;
    __u32 reserved0:13;
    __u32 frame_width:16;
    __u32 gamma_sc:5;
    __u32 reserved1:3;

};

look at all those bitfields, she's built different fr fr 💀✨

🌸 MEMBERS 🌸

okay let's go through every single one, no skipping, we don't do that here 💖

• dm_en — de-mosaic enable. that's it, that's the switch 👑
• ch_ar_en — Checker artifacts removal enable flag. Default 0. 🎀
• fcc_en — False color correction (FCC) enable flag. Default 0. 🌈
• reserved0 — reserved. hands off, bestie 🙈
• frame_width — do not care. literally the manpage's own words, she said idc 💀
• gamma_sc — Sharpening coefficient (coefficient of 2-d derivation of complementary color in Hamilton-Adams interpolation). It's u5, range [0, 31], default 8. ✨
• reserved1 — reserved. again. 🙈
• lc_ctrl — Parameter that controls weights of Chroma Homogeneity metric in calculation of final homogeneity metric. u5, range [0, 31], default 7. 🦋
• reserved2 — reserved. (the reserved fields are honestly just filler main characters) 💅
• cr_param1 — First parameter that defines Checker artifact removal feature gain. Precision u5, range [0, 31], default 8. 🔥
• reserved3 — reserved. 🫶
• cr_param2 — Second parameter that defines Checker artifact removal feature gain. Precision u5, range [0, 31], default 8. ⭐
• reserved4 — reserved. 🌸
• coring_param — Defines power of false color correction operation. low for preserving edge colors, high for preserving gray edge artifacts. Precision u1.4, range [0, 1.9375], default 4 (0.25). 🌺
• reserved5 — reserved. the final reserved. periodt. 💜

🎀 DESCRIPTION 🎀

so the demosaic fixed function block is responsible to covert Bayer(mosaiced) images into color images based on demosaicing algorithm. yes it says "covert" — that's the original wording, we're keeping it exactly, character for character 💖 the way this block just transforms your mosaiced pixels into actual color... obsessed.
