kthread_bind(9)

💅 kthread_bind 💅

okay so welcome to the Kernel API Manual page for kthread_bind — yes bestie, we're binding a just-created kthread to a cpu, and it's giving scheduler setup realness. 💖

🌟 NAME 🌟

kthread_bind — bind a just-created kthread to a cpu. Periodt. 💅

🦋 SYNOPSIS 🦋

void kthread_bind (struct task_struct *p , unsigned int cpu );

💖 ARGUMENTS 💖

• p — thread created by kthread_create. That's the fresh little kthread in question. 🧚
• cpu — cpu (might not be online, must be possible) for k to run on. Yep, it says k in the source; keep that energy. 👑

🔥 DESCRIPTION 🔥

okay so this function is equivalent to set_cpus_allowed, except that cpu doesn't need to be online, and the thread must be stopped (i.e., just returned from kthread_create). That's the whole thing. No cap. ✨

⚠️ The thread must be stopped — like, it just came back from kthread_create. This isn't a suggestion, bestie. 🫶
