arc_reg_set(9)

💅 arc_reg_set — the little register-setter that could ✨

okay so bestie, welcome to the arc_reg_set(9) page from the Kernel API Manual 🎀 this is the part where we teach a tiny kernel function to write a value into an EMAC register, and honestly? it's giving "small but iconic". 👑

---

🌸 NAME 🌸

arc_reg_set — sets an EMAC register with the value you hand it. literally that's the whole job and she does it with main character energy 💖

---

✨ SYNOPSIS ✨

void arc_reg_set (struct arc_emac_priv *priv , int reg , int value );

no cap, that's the signature — returns void, takes three things, done. 🫶

---

💅 ARGUMENTS 💅

• priv — a pointer to the ARC EMAC private data structure. like, the whole vibe of the device lives in there 🌈
• reg — the register offset from the base address. this is which register we're talking to, iykyk 📍
• value — the value to set in that register. the actual payload, the moment, the slay 💀✨

go read those too, bestie — the whole friend group is iconic 👯‍♀️

⭐ friendly reminder: everything above is exactly what the page says, no extras, no invented behaviour. if you need to know how it sets the register, that's a different page's problem 🙈

and that's a wrap on this one 🌸 this page came from ./drivers/net/ethernet/arc and it's dated October 2026, so like… mark your calendars, periodt. 💜
