node_update_perf_attrs(9)

💅 node_update_perf_attrs(9) — like, the Kernel API Manual, bestie ✨

Okay so picture this: it's giving "kernel API manual" energy, and the function is literally called node_update_perf_attrs. Say that five times fast, I dare you. 🫶

---

✨ NAME ✨

node_update_perf_attrs — updates the performance values for a given access class. That's it, that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

void node_update_perf_attrs (unsigned int nid , struct access_coordinate
*coord , enum access_coordinate_class access );

She returns void, bestie — no little return value to obsess over, she just does the thing. 💅

---

🦋 ARGUMENTS 🦋

• nid — the node identifier that's getting updated. Like, which node are we doing a glow-up on today? 👑
• coord — the heterogeneous memory performance coordinates. Yes, it's as much of a mouthful as it sounds, but she's iconic and she's carrying the actual perf numbers. ⭐
• access — the access class for the given attributes, i.e. which category of access these values belong to. Gotta label your stuff, periodt. 🏷️

ngl this page is lowkey short but she ate. No caveats, no weird bugs, no "undefined behaviour" jumpscare — just a clean little update function living her best life. 🌈

And that's the tea, bestie 🍓 — this cutie came to you from ./drivers/base (source/version tea), dated October 2026, and yes she's still serving node_update_perf_attrs(9) realness. Mwah! 😭💖🧚
