axienet_iow(9)

💅 axienet_iow — the Kernel API manual, bestie edition

Okay so picture this: we're deep in axienet_iow(9) territory — the Kernel API Manual page that basically teaches you how to write to a memory-mapped Axi Ethernet register. Slay. Let's get into it. ✨

---

🌸 SYNOPSIS 🌸

void axienet_iow (struct axienet_local *lp , off_t offset , u32 value );

Three little args, one void return, zero drama. Let's meet the cast 🎀

---

🫶 ARGUMENTS 🫶

• lp — a pointer to the axienet_local structure. Literally your main character struct, the one holding all the local state. 👑
• offset — the address offset, measured from the base address of the Axi Ethernet core. So like, where you're going relative to home base. 📍
• value — the value you want written into the Axi Ethernet register. The payload. The moment. The content. 💖

---

✨ DESCRIPTION ✨

This function writes the desired value into the corresponding Axi Ethernet register. That's the whole vibe check: you hand it a value, it lands in the right register. Memory-mapped, no cap. 🔥

It's giving "tiny function, big responsibility," honestly.

💀 Quick reminder bestie: axienet_iow writes, axienet_ior reads — don't get them twisted, iykyk.

And that's the page! 🧚✨ Brought to you straight from ./drivers/net/ethernet/xilinx, dated October 2026, running as axienet_iow(9) in the Kernel API Manual. Mwah 💋 — go write some registers, gorgeous. 🌈💜
