STRUCT IPU3_UAPI_FAR_W(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct ipu3_uapi_far_w(9) — from the Kernel API Manual 🎀

Okay so bestie, picture this: it's a manual page for struct ipu3_uapi_far_w, and its whole entire personality is "Sharpening config for far sub-group." That's it. That's the vibe. It's one little struct in the IPU3 camera pipeline that handles the far sub-group's sharpening settings, and honestly? She's small but she's doing the work. ✨

🌸 SYNOPSIS 🌸

Here's the whole struct, exactly as she lives in the header — no cap, this is verbatim:

struct ipu3_uapi_far_w {
    __u32 dir_shrp:7;
    __u32 reserved0:1;
    __u32 dir_dns:7;
    __u32 reserved1:1;
    __u32 ndir_dns_powr:7;
    __u32 reserved2:9;
 };

Look at those bitfields. The way she packs everything into __u32 with single-bit reserved gaps in between… it's giving "I have a very specific layout and I will not be deviating from it." 💀 Do not reorder these, bestie, the bit layout is the whole point.

🦋 Members 🦋

  • dir_shrp — the weight of wide direct sharpening. Precision is u1.6, range is [0, 64], and the default is 64. So she comes out of the box fully sharp. Main character energy, fr fr. 🔥
  • reserved0 — reserved. That's it. That's the whole description. Leave her alone. 🙈
  • dir_dns — the weight of wide direct denoising. Precision u1.6, range [0, 64], default 0. So unlike her sharpening sister, she starts at zero — no denoising until you ask for it. 💅
  • reserved1 — reserved. Again. Hands off. 🫶
  • ndir_dns_powr — the power of non-direct denoising. Precision u1.6, range [0, 64], default 64. Yes she's maxed out by default, and yes she's iconic for it. ⭐
  • reserved2 — reserved. Nine whole bits of "mind your business." 🌸
Heads up bestie: all three reserved fields are literally just padding in the bit layout. Don't go writing your own values in there, that's not the move. 🎀

Okay this is the part where the page goes absolutely feral with cross-references, and I respect it. Buckle up, we're listing every single one, because I'm not skipping a crumb. 👑

Like… that's a lot of structs. She knows everybody. Social butterfly of the intel-ipu3.h header, honestly. 🦋

And that's the page, bestie! 🌈 This cutie came out of ./drivers/staging/media/ipu3/i... and she's dated October 2026 — so go forth with your u1.6, your [0, 64] ranges, and your defaults of 64, 0, and 64, and sharpen those far sub-groups with confidence. You got this. Periodt. 💖✨🎀
