PROBE::SCHEDULER.T(3stap)

💖 probe::scheduler.tick — bestie edition 💖

okay so this is a page from the SystemTap Tapset Reference, manual section 3stap, and it's all about the probe point scheduler.tick. no cap, it's lowkey a tiny page but it's doing important work.

✨ NAME ✨

probe::scheduler.tick — it's the scheduler's internal tick, and when it fires, a process's timeslice accounting gets updated 🕰️

like, the kernel is literally doing the "how much CPU time have you used, babes" math. it's giving HR doing payroll but for timeslices.

---

🌸 SYNOPSIS 🌸

probe scheduler.tick {}

that's it. no arguments, no fancy params, just the probe point doing its thing. she's a simple girl and she ate 💅

---

🎀 VALUES 🎀

the values you can peek at inside this probe:

• idle — a boolean that tells you whether the current thing running is the idle process. so like, is the CPU just vibing with nothing to do? this tells you 👀
• name — the name of the probe point. yes bestie, it's just the name. every probe has one. it's her name tag at the party 🏷️

---

🦋 CONTEXT 🦋

the context here is: the process whose accounting will be updated.

so whoever's timeslice is getting recalculated? that's the main character of this probe. main character energy fr fr 👑
