💅 ks_pcie_intx_irq_handler(9) 💅

okay so bestie, this one lives in the Kernel API Manual and it's literally all about handling INTX interrupts. yes, that INTX. buckle up 🎀

---

✨ NAME ✨

ks_pcie_intx_irq_handler — handle an INTX interrupt, slay 💅

---

🌸 SYNOPSIS 🌸

void ks_pcie_intx_irq_handler (struct irq_desc *desc );

that's it. that's the whole vibe. returns nothing, takes one thing 🦋

---

🎀 ARGUMENTS 🎀

• desc — pointer to the irq descriptor, i.e. the little passport your interrupt carries so everyone knows who it is 🫶

---

⭐ DESCRIPTION ⭐

so what does it actually do, you ask? it traverses through all the pending INTX interrupts and invokes the handler for each one. every single one. no skipping, no leaving anyone on read 💖

and because that's not enough main character energy, it also takes care of the interrupt controller level mask/ack operation. mask it, ack it, iconic behavior only 👑

ngl if you were looking for something spicy and complicated here — this is it, that's the whole description. short, sweet, and does exactly what it says on the tin 🌈
