INTERRUPT_DISTRIBUTE(9)

💖 INTERRUPT_DISTRIBUTE(9) — Kernel Developer's Manual 💖

okay so bestie, this is the page for interrupt_distribute, and it's literally from the Kernel Developer's Manual. Buckle up — it's a short one, but it ate. 💅

🌸 NAME 🌸

interrupt_distribute — assign an interrupt to a CPU. periodt. ✨

✨ SYNOPSIS ✨

#include <sys/interrupt.h>

int
interrupt_distribute(void *ich, const kcpuset_t *newset,
    kcpuset_t *oldset);

💅 DESCRIPTION 💅

The interrupt_distribute function exists to assign an interrupt to a CPU. no cap, that's its whole main character job. 👑

If a driver (or the other kernel component) wishes to assign an interrupt to a CPU, it should pass an interrupt handler — such as the return value of pci_intr_establish() — as the ich argument. 🫶

Then it should pass the kcpuset to which it should be assigned as newset. Slay, that's the new set. 🌈

Wanna get the previous value? Pass a non-NULL value to oldset, bestie. That's the whole vibe check. 💖

💖 Sign-off: this is INTERRUPT_DISTRIBUTE(9) from Debian, dated August 17, 2015 — mwah, bestie 💋🫶
