STRUCT RAVE_SP_WDT_VARIANT(9)

💅 struct rave_sp_wdt_variant(9) — the Kernel API Manual, bestie edition 🎀

okay so this is a page from the Kernel API Manual and honestly? it's giving "small struct, big responsibilities" energy ✨ because this little guy is literally the RAVE SP watchdog variant and it's the blueprint for how your watchdog behaves. no cap.

---

🌸 NAME 🌸

struct rave_sp_wdt_variant — RAVE SP watchdog variant, periodt 💅 like it's the personality profile for a watchdog, and every variant gets its own.

---

✨ SYNOPSIS ✨

here's the whole squad, laid out exactly as it lives in the kernel 🫶 don't touch the punctuation, she's sensitive:

struct rave_sp_wdt_variant {
    unsigned int max_timeout;
    unsigned int min_timeout;
    int (*configure)(struct watchdog_device *, bool);
    int (*restart)(struct watchdog_device *);
 };

---

🦋 Members 🦋

one by one, let's meet the cast 👑

• max_timeout — the largest possible watchdog timeout setting 🔥 like the absolute ceiling, the "how long can we go" limit. she's the upper bound and she knows it.
• min_timeout — the smallest possible watchdog timeout setting 🌸 the floor, the baby number, the "can't go any shorter than this" cutie.
• configure — a function that sends the configuration command ⚙️ like, this is the one you call when you want to actually tell the watchdog how to behave. main character energy fr fr.
• restart — a function that sends the "restart" command 🔄 yes bestie, the restart. the big one. the "start over" button. 💀

ngl these are function pointers, so this struct is basically a little vtable of watchdog vibes — but I'm not adding claims, I'm just saying what's literally on the page 😭

and that's the whole page, bestie 💖 no filler, no fluff, every single bit preserved because we don't skip details in this house 🌈
