✨ ocxl_irq_set_handler(9) ✨

okay so this is a page from the Kernel API Manual bestie, and it's literally all about ocxl_irq_set_handler — the little function that hooks a callback onto an IRQ so your code gets pinged the moment that interrupt fires. 🎀

---

🌸 NAME 🌸

ocxl_irq_set_handler — provide a callback to be called when an IRQ is triggered. that's it, that's the whole job, and she does it beautifully 💅

---

🦋 SYNOPSIS 🦋

int ocxl_irq_set_handler (struct ocxl_context *ctx , int irq_id ,
irqreturn_t (*handler)(void *private) , void (*free_private)(void
*private) , void *private );

like yes she takes five arguments, don't panic, we're gonna go through every single one 🫶

---

💖 ARGUMENTS 💖

• ctx — the AFU context that the IRQ is associated with. this is your home base, your main character context ✨
• irq_id — the IRQ ID. yes. the ID of the IRQ. iconic of it honestly 💅
• handler — the callback to be called when the IRQ is triggered 🔥 this is the whole point, this is the moment
• free_private — the callback to be called when the IRQ is freed (may be NULL — so it's optional, no pressure bestie 🙈)
• private — private data to be passed to the callbacks. your little bag of secrets, handed straight to them 🎀

---

⭐ DESCRIPTION ⭐

Returns 0 on success, negative on failure. that's the whole description, she's a woman of few words and honestly? respect 😌💜

no cap, always check that return value — a negative number means something went sideways and you wanna know about it, fr fr.
