STRUCT IPU3_UAPI_IEFD_CUX6_ED(9)

💅 struct ipu3_uapi_iefd_cux6_ed 💅

okay bestie, welcome to the Kernel API Manual ✨ — this is the page for struct ipu3_uapi_iefd_cux6_ed, and yes the name is a whole keyboard smash but we're gonna get through it together 🫶

---

🌸 NAME 🌸

struct ipu3_uapi_iefd_cux6_ed — the struct that calculates the power of the non-directed sharpening element, aka Config Unit 6 for edge detail (ED) 💅 no cap, that's literally its job.

---

⭐ SYNOPSIS ⭐

here's the whole layout, character for character, do not touch, do not "clean up", just vibe with it 🎀

struct ipu3_uapi_iefd_cux6_ed {
    __u32 x0:9;
    __u32 x1:9;
    __u32 x2:9;
    __u32 reserved0:5;
    __u32 x3:9;
    __u32 x4:9;
    __u32 x5:9;
    __u32 reserved1:5;
    __u32 a01:9;
    __u32 a12:9;
    __u32 a23:9;
    __u32 reserved2:5;
    __u32 a34:9;
    __u32 a45:9;
    __u32 reserved3:14;
    __u32 b01:9;
    __u32 b12:9;
    __u32 b23:9;
    __u32 reserved4:5;
    __u32 b34:9;
    __u32 b45:9;
    __u32 reserved5:14;
 };

like, it's giving bitfield couture 💖 every one of these is a __u32 with a little slice carved out — the number after the colon is how many bits it gets. the reserved ones are the padding besties holding the seats so everything lines up 😌

🎀 Members 🎀

🌈 the X squad (points 0–5)

• x0 — X coordinate of point 0, u9.0, default 0. 🦋
• x1 — X coordinate of point 1, u9.0, default 0. 🦋
• x2 — X coordinate of point 2, u9.0, default 0. 🦋
• reserved0 — reserved. (it's just… there. minding its business 🙈)
• x3 — X coordinate of point 3, u9.0, default 0. 🦋
• x4 — X coordinate of point 4, u9.0, default 0. 🦋
• x5 — X coordinate of point 5, u9.0, default 0. 🦋
• reserved1 — reserved. (sequel to reserved0, same energy 💀)

note the type notation bestie: u9.0 = unsigned, 9 bits, zero fractional bits. the point is literally that pretty 💅

💜 the A slopes

• a01 — slope A points 01, s4.4, default 0. ✨
• a12 — slope A points 12, s4.4, default 0. ✨
• a23 — slope A points 23, s4.4, default 0. ✨
• reserved2 — reserved. (the intermission 🎀)
• a34 — slope A points 34, s4.4, default 0. ✨
• a45 — slope A points 45, s4.4, default 0. ✨
• reserved3 — reserved. (this one's the big one, 14 whole bits of nothing, iconic honestly 👑)

s4.4 = signed, 4 bits of integer, 4 bits of fraction. so she's got range, but she's also got a sign. respect 🌸

🦋 the B slopes

• b01 — slope B points 01, s4.4, default 0. 💜
• b12 — slope B points 12, s4.4, default 0. 💜
• b23 — slope B points 23, s4.4, default 0. 💜
• reserved4 — reserved. (the filler ep of the season 🙈)
• b34 — slope B points 34, s4.4, default 0. 💜
• b45 — slope B points 45, s4.4, default 0. 💜
• reserved5 — reserved. 🫶

so to recap the whole vibe: six X coords, five A slopes, five B slopes, and a whole supporting cast of reserved bitfields doing structural work so the struct stays 32-bit aligned-ish and gorgeous 😌✨ every single value defaults to 0, so a zeroed-out struct is a fully valid starting point fr fr.

🌟 bye bestie 🌟

that's the whole page! source/version line says ./drivers/staging/media/ipu3/i... and the date on it is October 2026 — so when you're reading this in the future, hi, ily, go read intel-ipu3.h 💖

now go set some slopes, hydrate, and slay 💅✨🍓
