STRUCT CHARGER_MANAGER(9)

💖 NAME 💖

struct charger_manager — okay so bestie, this is the manual page for it from the Kernel API Manual, and ngl the NAME line is out here giving absolutely nothing 😭 no description, no trailer, just the struct name and vibes. Iconic of it, honestly. So let's get into what's actually inside this thing.

---

✨ SYNOPSIS ✨

Here's the whole struct, copy-pasted with love, character for character:

struct charger_manager {
    struct list_head entry;
    struct device *dev;
    struct charger_desc *desc;
  #ifdef CONFIG_THERMAL;
    struct thermal_zone_device *tzd_batt;
  #endif;
    bool charger_enabled;
    int emergency_stop;
    char psy_name_buf[PSY_NAME_MAX + 1];
    struct power_supply_desc charger_psy_desc;
    struct power_supply *charger_psy;
    u64 charging_start_time;
    u64 charging_end_time;
    int battery_status;
 };

Notice tzd_batt is wrapped in #ifdef CONFIG_THERMAL; … #endif; — so if thermal config isn't on, that field simply does not exist. Lowkey a little main character of the preprocessor 🫶

🎀 MEMBERS 🎀

Time for the roster. Every field, one by one, no skips:

• entry — entry for list 💅 (yes bestie, it's a list entry, that's the whole job)
• dev — device pointer 🌸
• desc — instance of charger_desc
• tzd_batt — thermal zone device for battery 🔥 (only around when CONFIG_THERMAL says so)
• charger_enabled — the state of charger ⭐
• emergency_stop — when setting true, stop charging 💀 like actually, that's the whole deal
• psy_name_buf — the name of power-supply-class for charger manager 🎀 (buffer type is char psy_name_buf[PSY_NAME_MAX + 1], so it's sized for the max plus a terminator, cute)
• charger_psy — power_supply for charger manager 🔋
• charging_start_time — saved start time of enabling charging ⏰
• charging_end_time — saved end time of disabling charging ⏰
• battery_status — Current battery status 👑

Heads up bestie: charger_psy_desc (a struct power_supply_desc) is def in the struct up in the synopsis, but this Members list doesn't hand it a description. So no cap, I'm not gonna invent one for it — it's just there, living its truth 🙈

That's the whole page, bestie, you ate that 💅✨

Sign-off time: this one lives over in ./include/linux/power, and it's stamped October 2026. Go forth and manage those chargers 😭🫶🎀
