STRUCT KEYSTONE_TIMER(9)

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

okay so this is the page for struct keystone_timer(9) from the Kernel API Manual, and honestly? it's a little icon and it deserves your attention. it's giving "small struct, big job" energy ✨

---

🌸 NAME 🌸

struct keystone_timer — literally just holds timer's data 💖 no cap, that's the whole vibe. it's the container, it's the main character, it holds the timer's data. periodt.

---

✨ SYNOPSIS ✨

here's the whole entire glow-up, verbatim, don't touch it:

struct keystone_timer {
    void __iomem *base;
    unsigned long hz_period;
    struct clock_event_device event_dev;
 };

look at her. three members. flawless. no notes. 🫶

🦋 Members 🦋

• base — the timer memory base address. yes bestie, this is where the timer's memory lives, it's the address, the home base, the address of home 🏠
• hz_period — cycles per HZ period. that's cycles, per HZ period. an unsigned long of pure rhythm 🎵
• event_dev — the event device based on the timer. the struct clock_event_device that's built on top of this timer. it's the timer's whole personality tbh 👑

💜 SEE ALSO 💜

• Kernel file ./drivers/clocksource/timer-keystone.c — go read the source, iykyk 📖
• keystone_timer_barrier(9) — the barrier friend 🚧
• keystone_timer_config(9) — the config friend ⚙️

go look at all three, fr fr, they're a set, they're a trio, they're iconic together 🌈

lowkey a reminder: this page is just the shape of the struct — the docs don't promise anything about behaviour beyond what's written here, so don't go inventing semantics, bestie 💀

mwah 💋 that's the page! it lives in ./drivers/clocksource and it's dated October 2026 — yes, the future, she's ahead of her time ⭐👑 bye bestie, slay your timers 💅🎀
