axienet_tx_irq(9) — Tx Done Isr 💅

okay so bestie, we're in the Kernel API Manual and this page is literally the TX-done interrupt handler for Axi DMA. it's giving tiny-but-important kernel business, no cap ✨💅

---

✨ NAME ✨

axienet_tx_irq - Tx Done Isr. 💖

🌸 SYNOPSIS 🌸

irqreturn_t axienet_tx_irq (int irq , void *_ndev );

🦋 ARGUMENTS 🦋

• irq — the irq number 🔢
• _ndev — a net_device pointer 🫶

💜 RETURN 💜

• IRQ_HANDLED — if the device generated a TX interrupt 🔥
• IRQ_NONE — otherwise 💀

🌈 DESCRIPTION 🌈

okay so this is the Axi DMA Tx done Isr. It invokes NAPI polling to complete the TX BD processing. that's the whole vibe: TX done, NAPI polling, TX BD processing gets completed. iconic behavior honestly 👑✨
