💅 init_percpu_prof(9)

okay so bestie, welcome to the Kernel API Manual ✨ — yes that's the manual name, we're in the kernel docs honey, put your seatbelt on 🎀

🌸 NAME 🌸

init_percpu_prof — the function that enables/sets up per-cpu profiling hooks 🫶 like, it's supposed to be the girlboss that wires profiling up on each CPU, iykyk.

---

✨ SYNOPSIS ✨

void init_percpu_prof (unsigned long cpunum );

that's it. that's the whole signature. void return, one argument, no cap 💀

---

🦋 ARGUMENTS 🦋

• cpunum — the processor instance 🧚 that's the one you're pointing at, the specific CPU bestie, the whole vibe check of "which one"

---

💖 DESCRIPTION 💖

okay so here's the thing, and I need you to stay calm: the source literally says:

FIXME: doesn't do much yet...

😭😭😭 yeah. that's the description. it's giving "placeholder era", it's giving "under construction 🚧", it's giving "the function is a main character but the plot hasn't dropped yet". so like, it's meant to enable/setup per cpu profiling hooks, but rn? lowkey not doing a lot. slay anyway 💅
