zynqmp_dma_handle_ovfl_int(9)

✨ zynqmp_dma_handle_ovfl_int(9) — from the Kernel API Manual, bestie edition ✨

okay so picture this: it's a man page, it's in section 9, and it's about the ZynqMP DMA driver. literally the whole thing is one tiny function and it's gonna take you like two minutes. let's go 💅

---

🌸 NAME 🌸

zynqmp_dma_handle_ovfl_int — the one that handles the overflow interrupt. that's it, that's the job. the overflow interrupt gets processed, by this. iconic behavior honestly 🫶

---

✨ SYNOPSIS ✨

void zynqmp_dma_handle_ovfl_int (struct zynqmp_dma_chan *chan , u32
status );

notice the void? yeah. it returns nothing, it just does the thing 😌

---

🎀 ARGUMENTS 🎀

two arguments, both slaying in their own way:

• chan — the ZynqMP DMA channel pointer 💖 like, the actual channel we're talking about here
• status — the interrupt status value 🦋 the receipt, the proof, the number that says what's up
