STRUCT IPU3_UAPI_YUVP1_Y_EE_NR_FC_CORING_CONFIG(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct ipu3_uapi_yuvp1_y_ee_nr_fc_coring_config

okay so this is a page straight out of the Kernel API Manual, and it's genuinely a little gem. Slight problem: the man page title gets truncated in the header (struct ipu3...oring_config(9) — the terminal ate half of it 😭), so let's use the full name: struct ipu3_uapi_yuvp1_y_ee_nr_fc_coring_config. It's a struct, it lives in the kernel, and it's about coring. Buckle up 🎀

✨ NAME ✨

struct ipu3_uapi_yuvp1_y_ee_nr_fc_coring_config — literally the Luma(Y) edge enhancement noise reduction false color correction (FCC) coring config. That's the whole name, no cap. Luma(Y)! Edge enhancement! Noise reduction! False color correction! Coring config! All of it 🫶

🌸 SYNOPSIS 🌸

Here's the struct in all its bitfield glory — copy it exactly, bestie, don't you dare retype the numbers:

struct ipu3_uapi_yuvp1_y_ee_nr_fc_coring_config {
    __u32 pos_0:13;
    __u32 reserved0:3;
    __u32 pos_delta:13;
    __u32 reserved1:3;
    __u32 neg_0:13;
    __u32 reserved2:3;
    __u32 neg_delta:13;
    __u32 reserved3:3;
 };

The way it's just alternating 13-bit values and 3-bit reserved gaps? It's giving tidy. Periodt 💅

🦋 Members 🦋

Every single field, every single default, coming right up:

  • pos_0 — the gain for a positive edge in dark, u13.0, range [0, 16], default 0. Iconic.
  • reserved0 — reserved. Yes, reserved0 is reserved. Shocking, I know 🙈
  • pos_delta — the gain for a positive edge in bright. The value is pos_0 + pos_delta, and it has to be <=16 (u13.0), default 0. So it's a little add-on on top of pos_0, and if you blow past 16 that's on you 😭
  • reserved1 — reserved.
  • neg_0 — the gain for a negative edge in dark area, u13.0, range [0, 16], default 0.
  • reserved2 — reserved.
  • neg_delta — the gain for a negative edge in bright area. Value is neg_0 + neg_delta with <=16 (u13.0), default 0.
  • reserved3 — reserved.

Notice the pattern? pos_0/pos_delta for positive edges, neg_0/neg_delta for negative ones, and a reserved chaser after every single field. The 3-bit reserved bits are lowkey the main character of this struct ngl 👑

💖 Description 💖

Coring is a simple soft thresholding technique.

That's it. That's the description. Short, sweet, and honestly kind of mysterious — which is, of course, the most iconic thing a struct description can be ✨

Like… that's the whole camera pipeline in a list. Obsessed with the commitment honestly 🔥

💀 real talk: if you ever need to look up literally any other piece of the IPU3 params tree, it's on this list. intel-ipu3.h is the mothership, and everything above lives there. iykyk.

And that's the whole page, bestie 💜 This came from ./drivers/staging/media/ipu3/i..., dated October 2026, and the footer still insists on calling it struct ipu3...oring_config(9) because the terminal will never let a long struct name live. Slay, truncated king 🎀✨
