STRUCT GENI_SE(9)

💅 struct geni_se(9) — like, the GENI Serial Engine page, bestie

okay so this is from the Kernel API Manual, and it's literally the whole vibe of struct geni_se — the GENI Serial Engine. it's giving "small struct, big responsibilities." let's get into it 🫶

---

✨ NAME ✨

struct geni_se — GENI Serial Engine. that's it, that's the name, iconic 💅

---

🌸 SYNOPSIS 🌸

look at her. look at the whole struct. no cap, every field is right here:

struct geni_se {
    void __iomem *base;
    struct device *dev;
    struct geni_wrapper *wrapper;
    struct clk *clk;
    struct clk *core_clk;
    unsigned int num_clk_levels;
    unsigned long *clk_perf_tbl;
    struct geni_icc_path icc_paths[3];
    struct dev_pm_domain_list *pd_list;
    bool has_opp;
 };

like, she's got range. clock handles, ICC paths, a power domain list… main character energy fr fr 👑

🎀 Members 🎀

bestie, let's go field by field, one by one, no skipping, i promise:

• base — the Base Address of the Serial Engine's register block. like, where the registers actually live. home base 🏠
• dev — Pointer to the Serial Engine device. the device representation of this SE, right there.
• wrapper — Pointer to the parent QUP Wrapper core. yes, she has a parent. family business ✨
• clk — Handle to the core serial engine clock. the main clock glyph, and we respect her.
• core_clk — Auxiliary clock, which may be required by a protocol. aux queen 🎀
• num_clk_levels — Number of valid clock levels in clk_perf_tbl. a headcount, basically.
• clk_perf_tbl — Table of clock frequency input to serial engine clock. the whole menu of frequencies 🍓
• icc_paths — Array of ICC paths for SE. and it's an array of 3, exactly three, do not @ me.
• pd_list — Power domain list for managing power domains. she's managing domains, plural, like a boss.
• has_opp — Indicates if OPP is supported. simple, sweet, bool, tells you yes or no 😌

ngl that's the entire page — every field, every function reference, nothing skipped, periodt. go be obsessed with your serial engine 💖

sign-off szn: this page came from ./include/linux/soc/qcom and it's dated October 2026 — and the title/manual name is, again, struct geni_se(9) from the Kernel API Manual. mwah 💋 slay, bye bestie 🦋
