STRUCT CLOCKSOURCE_BASE(9)

💖 NAME 💖

Okay bestie, welcome to the Kernel API Manual page for struct clocksource_base(9) ✨ — it's literally the hardware abstraction for the clock on which a clocksource is based. No cap, it's giving foundation energy 💅.

✨ SYNOPSIS ✨

struct clocksource_base {
    enum clocksource_ids    id;
    u32 freq_khz;
    u64 offset;
    u32 numerator;
    u32 denominator;
 };

🎀 Members 🎀

• id — Defaults to CSID_GENERIC 👑. This id value is used by conversion functions that require the current clocksource to be based on a clocksource_base with a particular ID in certain snapshot functions, so callers can validate the clocksource from which the snapshot was taken. iykyk.
• freq_khz — Nominal frequency of the base clock in kHz 🩷.
• offset — Offset between the base clock and the clocksource 🌸.
• numerator — Numerator of the clock ratio between the base clock and the clocksource 💫.
• denominator — Denominator of the clock ratio between the base clock and the clocksource 🎀.
