💅 struct ipu3_uapi_isp_tnr3_vmem_params(9) — Kernel API Manual ✨

okay bestie, sit down, we're reading a kernel API manpage together and honestly? this one's kind of a vibe. it's from the Kernel API Manual, and it's all about struct ipu3_uapi_isp_tnr3_vmem_params — literally the Temporal noise reduction vector memory parameters. no cap, that's the whole NAME section. 🎀

🌸 NAME 🌸

struct ipu3_uapi_isp_tnr3_vmem_params — Temporal noise reduction vector memory parameters

like… the vector memory params for temporal noise reduction. it's giving "very specific camera tuning struct" and we respect it 💅

✨ SYNOPSIS ✨

here's the whole struct, bestie — copy it exactly, don't be weird about it:

struct ipu3_uapi_isp_tnr3_vmem_params {
    __u16 slope[IPU3_UAPI_ISP_TNR3_VMEM_LEN];
    __u16 reserved1[IPU3_UAPI_ISP_VEC_ELEMS -
IPU3_UAPI_ISP_TNR3_VMEM_LEN];
    __u16 sigma[IPU3_UAPI_ISP_TNR3_VMEM_LEN];
    __u16 reserved2[IPU3_UAPI_ISP_VEC_ELEMS -
IPU3_UAPI_ISP_TNR3_VMEM_LEN];
 };

four __u16 arrays, two of them doing the actual work and two of them just… existing. iconic honestly 🌈

🦋 Members 🦋

  • slope — the slope setting in the interpolation curve for temporal noise reduction. it's the how steep of the whole situation 📐
  • reserved1 — reserved. it's reserved, bestie, don't touch it 🙈
  • sigma — the knee point setting in the interpolation curve for temporal noise reduction. the knee point! where the curve bends! 💖
  • reserved2 — reserved. also reserved. also don't touch 💀
ngl the two reserved fields are sized IPU3_UAPI_ISP_VEC_ELEMS - IPU3_UAPI_ISP_TNR3_VMEM_LEN each, so they're lowkey padding the vector out. that's just what the struct says, no extras from me 🫶
