init_idle(9)

init_idle 💅

Okay bestie, welcome to the Kernel API Manual page for init_idle — the function that sets up an idle thread for a given CPU. 🎀✨

NAME 🦋

init_idle — set up an idle thread for a given CPU. periodt.

SYNOPSIS ⭐

void init_idle (struct task_struct *idle , int cpu );

ARGUMENTS 💖

• idle — the task in question, like literally the task we're talking about, bestie.
• cpu — the CPU the idle task belongs to.

NOTE 🙈

This function does not set the idle thread's NEED_RESCHED flag, and that's intentional — it makes booting more robust. no cap.
