STRUCT AB8500_FG_PARAMETERS(9)

💅 struct ab8500_fg_parameters(9) — the full glow-up

okay so this is a page from the Kernel API Manual, and it's literally all about struct ab8500_fg_parameters — the fuel gauge algorithm parameters, bestie. every value is in seconds unless it says otherwise (yes, the page says that up front, iconic of it).

✨ NAME ✨

struct ab8500_fg_parameters — Fuel gauge algorithm parameters, in seconds if not specified 🫶

---

🎀 SYNOPSIS 🎀

struct ab8500_fg_parameters {
    int recovery_sleep_timer;
    int recovery_total_time;
    int init_timer;
    int init_discard_time;
    int init_total_time;
    int high_curr_time;
    int accu_charging;
    int accu_high_curr;
    int high_curr_threshold_ua;
    int lowbat_threshold_uv;
    int battok_falling_th_sel0;
    int battok_raising_th_sel1;
    int user_cap_limit;
    int maint_thres;
    bool pcut_enable;
    u8 pcut_max_time;
    u8 pcut_flag_time;
    u8 pcut_max_restart;
    u8 pcut_debounce_time;
 };

like, look at her. a whole little family of ints and a few u8s. no cap, she's serving struct. 💅

🌸 Members 🌸

okay bestie, member-by-member, and we're not skipping a single one:

• recovery_sleep_timer — the time between measurements while recovering 😴
• recovery_total_time — the total recovery time, start to finish
• init_timer — the measurement interval during startup ⏱️
• init_discard_time — the time we discard voltage measurement at startup (throwing it out, we don't want it)
• init_total_time — the total init time during startup
• high_curr_time — how long the current has to be high before we go to recovery 🔥
• accu_charging — the FG accumulation time while charging 🔋
• accu_high_curr — it's right there in the struct, but this page doesn't hand it its own blurb. iykyk, moving on 🙈
• high_curr_threshold_ua — the high current threshold, in uA
• lowbat_threshold_uv — the low battery threshold, in uV
• battok_falling_th_sel0 — the threshold in mV for the battOk signal sel0; resolution in 50 mV steps.
• battok_raising_th_sel1 — the threshold in mV for the battOk signal sel1; resolution in 50 mV steps.
• user_cap_limit — the capacity reported from the user has to be within this limit to be considered sane, in percentage points (fr fr, sane or nothing)
• maint_thres — the threshold where we stop reporting battery full while in maintenance, in per cent 👑
• pcut_enable — enables the power cut feature in ab8505 ✂️
• pcut_max_time — the max time threshold
• pcut_flag_time — the flagtime threshold 🚩
• pcut_max_restart — the max number of restarts
• pcut_debounce_time — sets the battery debounce time

ngl, that run of battok/user_cap_limit/maint_thres entries is exactly the kind of thing that gets squished together in a raw manpage. we've un-squished them here, but every threshold, unit and step size is untouched. 💖

⭐ the sign-off ⭐

this little masterpiece lives in ./drivers/power/supply, it's dated October 2026, and it answers to struct ab8500_fg_parameters(9). that's the whole page — you ate, you slayed, go read ab8500-bm.h now. periodt. 💜✨🎀
