STRUCT IPU3_UAPI_ISP_TNR3_PARAMS(9)

🎀 struct ipu3_uapi_isp_tnr3_params(9) 🎀

okay so bestie, welcome to the Kernel API Manual 💅 this one's about struct ipu3_uapi_isp_tnr3_params, and it is literally the main character of temporal noise reduction v3. no cap, she's the whole vibe.

---

✨ NAME ✨

struct ipu3_uapi_isp_tnr3_params — Temporal noise reduction v3 parameters 🦋

like… the parameter bundle for TNR3. that's it, that's the tweet.

---

✨ SYNOPSIS ✨

struct ipu3_uapi_isp_tnr3_params {
    __u32 knee_y1;
    __u32 knee_y2;
    __u32 maxfb_y;
    __u32 maxfb_u;
    __u32 maxfb_v;
    __u32 round_adj_y;
    __u32 round_adj_u;
    __u32 round_adj_v;
    __u32 ref_buf_select;
 };

look at her. nine __u32 fields, all lined up, absolute icon behavior 👑

✨ Members ✨

• knee_y1 — the knee point where TNR3 assumes the standard deviation of Y, U and V at Y1 are TnrY1_Sigma_Y, U and V. iykyk 💫
• knee_y2 — the knee point where TNR3 assumes the standard deviation of Y, U and V at Y2 are TnrY2_Sigma_Y, U and V. same energy, second knee 🦵
• maxfb_y — max feedback gain for Y 🔥
• maxfb_u — max feedback gain for U 🔥
• maxfb_v — max feedback gain for V 🔥
• round_adj_y — rounding adjust for Y 🎀
• round_adj_u — rounding adjust for U 🎀
• round_adj_v — rounding adjust for V 🎀
• ref_buf_select — selection of the reference frame buffer to be used. she picks the reference frame, periodt 🫶
