STRUCT IPU3_UAPI_IEFD_CUX2_1(9)

📦 version 7.3.1, in nixpkgs unstable

💖 struct ipu3_uapi_iefd_cux2_1 — like, the whole manual, but make it make sense 💖

okay bestie, so this is a page from the Kernel API Manual — the struct ipu3_uapi_iefd_cux2_1(9) one — and it's actually so niche and so specific and honestly? iconic for that. it's all about calculating the power of the non-directed denoise element apply. yes, that's the whole vibe. denoise math. slay.

✨ NAME ✨

struct ipu3_uapi_iefd_cux2_1 — Calculate power of non-directed denoise element apply.

like, that's it, that's her job. she does the power math for the non-directed denoise element apply and she does it well. no notes. 💅

🎀 SYNOPSIS 🎀

here's the actual struct, character for character, no cap:

struct ipu3_uapi_iefd_cux2_1 {
    __u32 x0:9;
    __u32 x1:9;
    __u32 a01:9;
    __u32 reserved1:5;
    __u32 b01:8;
    __u32 reserved2:24;
 };

look at those bitfields. tiny. precise. main character energy. 🦋

🌸 Members 🌸

okay so let's meet the cast, one bitfield at a time:

  • x0 — the X0 point of the Config Unit, and she's u9.0 with a default of 0. yes bestie, unsigned, nine bits, whole numbers only. 🫶
  • x1 — the X1 point of the Config Unit, also u9.0, also defaulting to 0. her and x0 are literally a matching set. 💖
  • a01 — the Slope A of the Config Unit. this one's s4.4 (signed! fancy!) and defaults to 0. slope girlies rise up. 🔥
  • reserved1 — reserved. that's it, that's the whole description. she's just holding space. reserved. we respect her privacy. 🙈
  • b01 — the offset B0 of the Config Unit, u7.0, default 0. note that the field is named b01 but the description says "offset B0" — that's just how it is, don't come for me, I'm reporting the facts. ⭐
  • reserved2 — reserved. again. reserved squared. reserved part two: electric boogaloo. 💀

🦋 SEE ALSO 🦋

okay so buckle up because this list is long. like, genuinely enormous. the kernel file you want is:

whew. okay. that's everybody. literally the entire IPU3 extended family showed up to the group chat. 💜

ngl, if you're reading this page you probably came here from the intel-ipu3.h header — go say hi to the neighbors, they're all listed above and they're all lovely.

and that's the page!! 🎀 this little cutie comes to you from ./drivers/staging/media/ipu3/i..., dated October 2026, and she's filed under struct ipu3_..._iefd_cux2_1(9) — go forth and denoise, bestie, ily, bye!! 🌈✨💖
