STRUCT IPU3_UAPI_YUVP1_IEFD_CONTROL(9)

🌸 NAME 🌸

okay so bestie, meet struct ipu3_uapi_yuvp1_iefd_control — the IEFd control struct, section 9 of the Kernel API Manual. she's a tiny __u32 of bitfields whose entire personality is "which IEFd things are turned on" and honestly? relatable. no cap, every single switch in here is a one-bit yes/no and the rest is just vibes (reserved).

---

✨ SYNOPSIS ✨

like, literally the whole thing:

struct ipu3_uapi_yuvp1_iefd_control {
    __u32 iefd_en:1;
    __u32 denoise_en:1;
    __u32 direct_smooth_en:1;
    __u32 rad_en:1;
    __u32 vssnlm_en:1;
    __u32 reserved:27;
 };

five little one-bit switches plus a reserved:27 — that's 32 bits of __u32, the math is mathing 💅

---

🎀 MEMBERS 🎀

• iefd_en — the main character switch: enables IEFd 🔥
• denoise_en — enables denoise. bye bye noise, hiiii smoothness ✨
• direct_smooth_en — enables directional smooth 🫶
• rad_en — enables radial update 🌈
• vssnlm_en — enables the VSSNLM output filter 👑
• reserved — reserved. literally just sitting there holding 27 bits, do not touch, she's booked 🙈
