generic_handle_irq_safe(9)

📦 version 7.3.1, in nixpkgs unstable

💅 generic_handle_irq_safe — like, the manual page

okay so this is generic_handle_irq_safe(9) from the Kernel API Manual (yes bestie, the kernel has lore too) and honestly? she's a little icon. let's get into it 🎀

✨ NAME ✨

generic_handle_irq_safe — invoke the handler for a particular irq from any context. literally any. no cap. 🦋

🌸 SYNOPSIS 🌸

int generic_handle_irq_safe (unsigned int irq );

that's it, that's the whole vibe check. one arg. 💅

🧚 ARGUMENTS 🧚

  • irq — the irq number to handle. this is the one (1) thing you give her, and she handles it. main character energy fr fr 👑

⭐ RETURN ⭐

  • 0 on success 🎉
  • a negative value on error 😭

that's the whole story, no plot twist. 💀

💖 DESCRIPTION 💖

okay so here's the tea ☕ — this function can be called from any context, and I mean any: IRQ context or process context, she does not care, she's flexible like that 🧘‍♀️✨

but — and this is the important part, ngl — she'll report an error if you call her when you're not in IRQ context and the irq has been marked to enforce IRQ-context only. so like... read the room, bestie. 🙈 if that irq said "IRQ context only" she meant it, and you're gonna get an error, not a slay. 🫶

🔥 SEE ALSO 🔥

the whole friend group 🫂 — and yeah, she lives in the kernel file ./kernel/irq/irqdesc.c, iykyk:

lowkey a reminder: that error only hits when you're outside IRQ context and the irq is marked IRQ-context-only. don't say I didn't warn you 💀

and that's the page, bestie!! 🌈 this whole thing ships out of ./kernel/irq, dated October 2026, and yeah — the page is literally named generic_handle_irq_safe(9) because of course it is. go forth and handle those irqs safely, mwah 💋🎀✨🌸
