kthread_create_on_cpu(9)

📦 version 7.3.1, in nixpkgs unstable

💅 kthread_create_on_cpu(9) — from the Kernel API Manual, bestie

okay so this is kthread_create_on_cpu(9), straight out of the Kernel API Manual, and it's literally the glow-up helper for making a cpu bound kthread. like, binding a thread to one specific cpu? iconic. let's get into it 🎀

✨ NAME ✨

kthread_create_on_cpu — Create a cpu bound kthread 🌸

✨ SYNOPSIS ✨

struct task_struct * kthread_create_on_cpu (int (*threadfn)(void *data)
, void *data , unsigned int cpu , const char *namefmt );

it returns a struct task_struct *, no cap 💖

✨ ARGUMENTS ✨

  • threadfn — the function that's gonna run, and it keeps running until signal_pending(current). that's the whole vibe, she goes until she's told to stop 🫶
  • data — the data ptr you're handing off to threadfn. her little care package 💜
  • cpu — the cpu where the thread should be bound. yes bestie, that one, specifically 👑
  • namefmt — printf-style name for the thread. and here's the catch: format is restricted to "name.*u". the code fills in the cpu number itself. so don't get creative with it 💅

✨ DESCRIPTION ✨

so literally what this does: this helper function creates and names a kernel thread. that's it. that's the whole thing. create ✨ and name ✨ and it's cpu bound because that's the whole point of the helper, see the cpu argument 🔥

ngl that's the entire description, short and sweet, main character energy fr fr 💀
