STRUCT TTC_TIMER(9)

💜 struct ttc_timer(9) 💜

okay so this is a page straight out of the Kernel API Manual, bestie — it's all about struct ttc_timer, and ngl it's a short one but it's lowkey iconic. let's get into it ✨

---

🌸 NAME 🌸

struct ttc_timer — this definition defines the local timer structure. that's it, that's the vibe. it's the struct itself, she's the main character 🎀

---

🦋 SYNOPSIS 🦋

struct ttc_timer {
    void __iomem *base_addr;
    unsigned long freq;
    struct clk *clk;
    struct notifier_block clk_rate_change_nb;
 };

literally the whole thing, no cap. copy it exactly, don't be out here renaming fields 🙈

✨ Members ✨

• base_addr — base address of the timer. like, where she lives 💅
• freq — the timer input clock frequency. her whole tempo, fr fr.
• clk — the associated clock source. every timer needs her clock bestie 🫶
• clk_rate_change_nb — notifier block for clock rate changes. so when the clock rate shifts, this one gets the heads-up. the way that this keeps her in the loop 😭💖

lowkey a reminder bestie: the members list is the whole documentation here — don't go assuming extra behaviour that isn't written down. the manpage said what it said, periodt 💅

and that's a wrap, gorgeous 🧚‍♀️ this page came from ./drivers/clocksource and it's dated October 2026 — so yeah, future-coded and flawless. mwah 💋⭐🌸
