xilinx_dma_irq_handler(9)

💖 NAME 💖

okay bestie, welcome to the Kernel API Manual page for xilinx_dma_irq_handler(9) — yes that whole mouthful is the name, and it is literally just the DMA Interrupt handler. that's it. that's the whole identity. iconic minimalism honestly 🎀

---

✨ SYNOPSIS ✨

irqreturn_t xilinx_dma_irq_handler (int irq , void *data );

like, copy it exactly, don't freestyle the signature, i'm begging 🙏

---

🎀 ARGUMENTS 🎀

• irq — the IRQ number. yes, the actual interrupt number, the "who pinged me" of it all 💅
• data — a pointer to the Xilinx DMA channel structure. it's giving "i brought the whole channel with me" energy 🦋

---

🔥 RETURN 🔥

IRQ_HANDLED/IRQ_NONE — those are your two return options, periodt. no cap, that's the entire return story 💀
