STRUCT VIORTC_CLASS(9)

💖 struct viortc_class(9) 💖

okay so bestie, welcome to the struct viortc_class(9) page from the Kernel API Manual — yes, the whole manual, and yes, this one lil struct is the main character today 👑

---

✨ NAME ✨

struct viortc_class — the RTC class wrapper, and honestly it's giving "small but crucial" 🎀

---

🌸 SYNOPSIS 🌸

struct viortc_class {
    struct viortc_dev *viortc;
    struct rtc_device *rtc;
    u16 vio_clk_id;
    bool stopped;
 };

no cap, that's the whole thing. four fields. four. and every single one of them is doing something 💅

🦋 Members 🦋

• viortc — the virtio_rtc device data, aka where the virtio side of the story lives 🫶
• rtc — the RTC device. yep, the actual real-time-clock device, iconic ⭐
• vio_clk_id — the virtio_rtc clock id. it's a u16, she's little, she's fierce 🎀
• stopped — whether RTC ops are disallowed or not 👀 heads up bestie: access to this is protected by rtc_lock, so like, don't just vibe in there without the lock, fr fr 🔥

ngl, take the locking note seriously — the manpage says access is protected by rtc_lock, and we are not out here freelancing 😭
