✨ xdma_channel_isr(9) ✨

okay so bestie, you found the page for xdma_channel_isr — it's literally the XDMA channel interrupt handler, living its best life in the Kernel API Manual 💅 no cap, that's the whole vibe of this one.

🌸 NAME 🌸

xdma_channel_isr — XDMA channel interrupt handler 🎀

Like, the moment something goes ping! on an XDMA channel, this is the function that picks up the phone 📞✨

---

🦋 SYNOPSIS 🦋

irqreturn_t xdma_channel_isr (int irq , void *dev_id );

that's it, that's the whole signature 👑 take it exactly as written, don't come for me about the spacing, it's canon fr fr

---

💖 ARGUMENTS 💖

• irq — the IRQ number 🌈 like, which interrupt line is yapping at you rn
• dev_id — a pointer to the DMA channel structure 🫶 this is the little handle that tells you which channel we're dealing with, iykyk
