ENUM RKISP1_CIF_ISP_DPF_GAIN_USAGE(9)

💅 enum rkisp1_cif_isp_dpf_gain_usage — dpf gain usage 💅

okay bestie, so this one is a page from the Kernel API Manual (that's the manual name, iykyk) and it's literally all about one enum. tiny page, big main character energy. let's get into it 🫶

✨ NAME ✨

enum rkisp1_cif_isp_dpf_gain_usage — dpf gain usage. that's it. that's the whole name. no cap.

---

🌸 SYNOPSIS 🌸

enum rkisp1_cif_isp_dpf_gain_usage {
    RKISP1_CIF_ISP_DPF_GAIN_USAGE_DISABLED ,
    RKISP1_CIF_ISP_DPF_GAIN_USAGE_NF_GAINS ,
    RKISP1_CIF_ISP_DPF_GAIN_USAGE_LSC_GAINS ,
    RKISP1_CIF_ISP_DPF_GAIN_USAGE_NF_LSC_GAINS ,
    RKISP1_CIF_ISP_DPF_GAIN_USAGE_AWB_GAINS ,
    RKISP1_CIF_ISP_DPF_GAIN_USAGE_AWB_LSC_GAINS ,
    RKISP1_CIF_ISP_DPF_GAIN_USAGE_MAX

};

look at her go 💖 seven constants, all lined up, all gorgeous.

👑 CONSTANTS 👑

• RKISP1_CIF_ISP_DPF_GAIN_USAGE_DISABLED — don't use any gains in preprocessing stage. like, zero gains. none. we're on a gains cleanse 🧚
• RKISP1_CIF_ISP_DPF_GAIN_USAGE_NF_GAINS — use only the noise function gains from registers DPF_NF_GAIN_R, ... (yes the ... is doing a lot of heavy lifting there, that's how the original wrote it, respect it 💅)
• RKISP1_CIF_ISP_DPF_GAIN_USAGE_LSC_GAINS — use only the gains from the LSC module 🌈
• RKISP1_CIF_ISP_DPF_GAIN_USAGE_NF_LSC_GAINS — use the noise function gains and the gains from the LSC module. both. a collab 🤝
• RKISP1_CIF_ISP_DPF_GAIN_USAGE_AWB_GAINS — use only the gains from the AWB module ✨
• RKISP1_CIF_ISP_DPF_GAIN_USAGE_AWB_LSC_GAINS — use the gains from AWB and LSC module. another collab, ate 💅
• RKISP1_CIF_ISP_DPF_GAIN_USAGE_MAX — upper border (only for an internal evaluation). it's giving "don't touch, that's for the internals" energy 🚧

this lil masterpiece lives in ./include/uapi/linux and the version stamp says October 2026 — so yeah, she's from the future, iconic behavior honestly. go read your kernel headers bestie, ily, bye 💜🦋✨
