dpu_core_irq...ter_callback(9)

💅 dpu_core_irq_unregister_callback (9) — from the Kernel API Manual, bestie

okay so picture this: it's a kernel API manual page, the title's literally dpu_core_irq...ter_callback(9) (yes the truncation is part of the vibe, we don't fix it, we respect it), and it's all about un-registering a callback on an IRQ interrupt. Let's get into it ✨

---

🌸 NAME 🌸

dpu_core_irq_unregister_callback — for unregistering a callback function on an IRQ interrupt. that's it, that's the whole job. it takes your callback off the interrupt's guest list 💅

---

🦋 SYNOPSIS 🦋

int dpu_core_irq_unregister_callback (struct dpu_kms *dpu_kms , unsigned
int irq_idx );

copy it exactly, bestie, don't be cute with the spacing 🫶

---

🎀 ARGUMENTS 🎀

• dpu_kms — the DPU handle. your whole DPU situation, hand it over 💖
• irq_idx — the irq index. which interrupt we're talking about, index edition 🔥

---

⭐ RETURN ⭐

0 for success registering callback, otherwise failure.

ngl the wording says "registering" even though we're literally unregistering — that's what the page says, so that's what you get 🙈 0 = good, anything else = not good, periodt.

---

✨ DESCRIPTION ✨

This function supports registration of multiple callbacks for each interrupt.

lowkey iconic? one interrupt, multiple callbacks, all living their main character lives. and this function is the one that removes one of them 💀✨
