STRUCT RIO_DRIVER(9)

💖 struct rio_driver(9) — RIO driver info 💖

okay so bestie, welcome to the struct rio_driver(9) page from the Kernel API Manual — yes that's the manual name, keep it in your notes 📓 — this is the whole vibe of what a RIO driver looks like to the kernel. no cap, it's the little bundle of info that tells everyone what your driver is and what it can do 🎀

✨ NAME ✨

struct rio_driver — RIO driver info 🦋

---

🌸 SYNOPSIS 🌸

here's the whole struct, literally copy it exactly, do not freelance:

struct rio_driver {
    struct list_head node;
    char *name;
    const struct rio_device_id *id_table;
    int (*probe) (struct rio_dev * dev, const struct rio_device_id *id);
    void (*remove) (struct rio_dev * dev);
    void (*shutdown)(struct rio_dev *dev);
    int (*suspend) (struct rio_dev * dev, u32 state);
    int (*resume) (struct rio_dev * dev);
    int (*enable_wake) (struct rio_dev * dev, u32 state, int enable);
    struct device_driver driver;
 };

👑 Members 👑

bestie these are the fields, one by one, no skipping, we don't do that here 💅

• node — the node in the list of drivers, it's how you get linked up 🔗
• name — the RIO driver name, your driver's whole identity ✨
• id_table — the RIO device ids that get associated with this driver, like your driver's type 🫶
• probe — fires when a RIO device is inserted 👀
• remove — fires when a RIO device is removed 😭
• shutdown — the shutdown notification callback 💀
• suspend — RIO device suspended, it's napping 😴
• resume — RIO device awakened, she's up again 🌞
• enable_wake — RIO device enable wake event ⏰
• driver — the LDM driver struct, the underlying main character 🌈

🧚 Description 🧚

so what does this actually do? it provides info on a RIO device driver for insertion/removal and power management purposes. that's the whole gig — it's giving "organized and functional" and honestly? obsessed 💜
