💜 irq_get_irqchip_state(9) — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual, this is the page for irq_get_irqchip_state(9) and it's lowkey one of those tiny functions that does exactly one thing and does it slay 💅

🌸 NAME 🌸

irq_get_irqchip_state — returns the irqchip state of a interrupt. fr fr that's the whole job 🎀

✨ SYNOPSIS ✨

int irq_get_irqchip_state (unsigned int irq , enum irqchip_irq_state
which , bool *state );

like, three args in, one int out, no cap 🫶

🦋 ARGUMENTS 🦋

  • irq — the interrupt line that is forwarded to a VM. that's your main character interrupt 👑
  • which — one of the IRQCHIP_STATE_* values — specifically whichever one the caller wants to know about 👀
  • state — a pointer to a bool, and this is where the state gets stored. put it somewhere valid bestie, it's writing through it 💖

🔥 DESCRIPTION 🔥

so what this call does is it snapshots the internal irqchip state of an interrupt — like a little screenshot of the moment 📸 — and then returns into state the bit that corresponds to stage which.

⚠️ important vibe check: this function should be called with preemption disabled if the interrupt controller has per-cpu registers. do not skip that. that's not a suggestion, that's the rule 😭

🌈 SEE ALSO 🌈

the kernel file ./kernel/irq/manage.c and like... a whole friend group of functions, honestly, they all travel together 🧚‍♀️

that's the whole page, you ate it 💅 ok bye, this one's filed under ./kernel/irq and it's dated October 2026 — iconic of it honestly 🎀💖✨
