✨ PROBE::VM.MMAP ✨

okay bestie, welcome to the Memory Tapset section of the SystemTap Tapset Reference (section 3stap, iykyk) 💖 this is the page for one very specific little guy and honestly? it's giving main character energy for about half a millisecond.

🦋 NAME 🦋

probe::vm.mmap — fires when an mmap is requested 👀

like. the moment somebody asks the kernel for some memory to be mapped. that's the vibe check. that's when it goes off.

---

🌸 SYNOPSIS 🌸

probe vm.mmap {}

no arguments, no fancy params, just. the probe. sitting there. waiting. periodt. 💅

---

🎀 VALUES 🎀

these are the read-only goodies you can peek at when the probe fires, and ngl they're all super useful:

• length — the length of the memory segment 📏 that's how much memory got requested, bestie.
• name — name of the probe point 🏷️ yes, the probe point's own name. iconic of it.
• address — the requested address 📍 the address that got asked for, right there.

these are context variables, so you read them, you don't write them. respect the boundary fr fr 🙈

💜 CONTEXT 💜

the process calling mmap. 🫶

that's it. that's the context. whoever called mmap is the one you're looking at when this fires. keep your eyes on them, they're the whole story. ✨
