tk_setup_internals(9)

🎀 tk_setup_internals(9) 🎀

hiii bestie 🫶 welcome to the Kernel API Manual page for tk_setup_internals(9) — yes, we're doing kernel timekeeping internals today, and the vibes are immaculate but the rules are strict 💅.

🌸 NAME 🌸

tk_setup_internals — Set up internals to use clocksource clock.

✨ SYNOPSIS ✨

void tk_setup_internals (struct timekeeper *tk , struct clocksource
       *clock );

🦋 ARGUMENTS 🦋

• tk — the target timekeeper to setup, okay bestie?
• clock — pointer to clocksource. iconic. 💫

💖 DESCRIPTION 💖

okay so check it: this calculates a fixed cycle/nsec interval for a given clocksource/adjustment pair and interval request. that's the tea ☕.

⚠️ Unless you're the timekeeping code, you should not be using this! no cap, this is not a casual Friday API, bestie. 💀

it's giving internal-only energy, and honestly? respect. 🫡
