💅 qla4_8xxx_de...intr_handler(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a kernel page, and the title's lowkey truncated in the header (it's qla4_8xxx_de...intr_handler(9), the ... is giving "we ran out of characters" energy) but the real name is right down there in NAME, so let's go 🫶

---

✨ NAME ✨

qla4_8xxx_default_intr_handler — the hardware interrupt handler. that's it, that's the vibe 💅

---

🌸 SYNOPSIS 🌸

irqreturn_t qla4_8xxx_default_intr_handler (int irq , void *dev_id );

she takes two args and hands you back an irqreturn_t. iconic signature, no notes 💖

---

🎀 ARGUMENTS 🎀

• irq — literally unused. not used, not touched, not thought about. she's just there for the vibes 🙈
• dev_id — a pointer to the host adapter structure. this is the one that actually matters ✨

---

🦋 DESCRIPTION 🦋

okay so here's the tea: this interrupt handler gets called directly for MSI-X, and indirectly for MSI 🫶 that's the whole deal, no cap.
