STRUCT HRTIMER_CLOCK_BASE(9)

✨ NAME ✨

okay bestie, welcome to the struct hrtimer_clock_base(9) page from the Kernel API Manual 💖 this is literally the timer base for a specific clock. that's the whole vibe. no cap.

🌸 SYNOPSIS 🌸

       struct hrtimer_clock_base {
           struct hrtimer_cpu_base         *cpu_base;
           const unsigned int              index;
           const clockid_t                 clockid;
           seqcount_raw_spinlock_t seq;
           ktime_t expires_next;
           struct hrtimer                  *running;
           struct timerqueue_linked_head   active;
           ktime_t offset;
        };

🎀 Members 🎀

• cpu_base — per cpu clock base. iconic. essential. doing its little per-cpu thing 💅
• index — clock type index for per_cpu support when moving a timer to a base on another cpu. yes, it's giving "I know where I belong" energy ✨
• clockid — clock id for per_cpu support. short, sweet, slay.
• seq — seqcount around __run_hrtimer. she's the sequencing bestie 🫶
• expires_next — Absolute time of the next event in this clock base. highkey important ⏰
• running — pointer to the currently running hrtimer. main character pointer energy, fr fr 👑
• active — red black tree root node for the active timers. tree root but make it fashion 🌈
• offset — offset of this clock to the monotonic base. little offset, big role 💜
