STRUCT EDAC_ECS_OPS(9)

💅 struct edac_ecs_ops(9) — Kernel API Manual

okay bestie, welcome to the ECS device operations vibe check ✨ this is struct edac_ecs_ops, and the headline is: every single element is optional. no cap. all of them. it's giving "choose your own adventure" but make it kernel 💖

---

✨ SYNOPSIS ✨

struct edac_ecs_ops {
    int (*get_log_entry_type)(struct device *dev, void *drv_data, int fru_id, u32 *val);
    int (*set_log_entry_type)(struct device *dev, void *drv_data, int fru_id, u32 val);
    int (*get_mode)(struct device *dev, void *drv_data, int fru_id, u32 *val);
    int (*set_mode)(struct device *dev, void *drv_data, int fru_id, u32 val);
    int (*reset)(struct device *dev, void *drv_data, int fru_id, u32 val);
    int (*get_threshold)(struct device *dev, void *drv_data, int fru_id, u32 *threshold);
    int (*set_threshold)(struct device *dev, void *drv_data, int fru_id, u32 threshold);
};

like, look at that. a whole little squad of function pointers, all riding the same struct device *dev, void *drv_data, int fru_id trio 🫶 iconic.

🎀 Members 🎀

okay so here's the roster, one by one, and yes they're all optional so don't come for me 💅

• get_log_entry_type — reads the log entry type value. that's it, that's the whole job 🌸
• set_log_entry_type — sets the log entry type value. the setter to the getter's getter, if you will ✨
• get_mode — reads the mode value 👑
• set_mode — sets the mode value 💜
• reset — resets the ECS counter. clean slate energy, we love a fresh start 🦋
• get_threshold — reads the threshold count per gigabits of memory cells. yes, per gigabits, that's the unit, don't @ me 🍓
• set_threshold — sets the threshold count per gigabits of memory cells. same unit, different direction 💫

ngl the fact that literally every element here is optional is the whole personality of this struct. it's a menu, bestie, not a contract 💀
