rd32(9)

💖 rd32(9) — the tiny register-reading icon ✨

okay so bestie, welcome to the Kernel API Manual, section 9 🎀 today we're talking about rd32, and honestly? she's small, she's simple, she eats every time 💅

---

🌸 NAME 🌸

rd32 — read a 32 bit hw register 🫶

like literally that's it, that's her whole job, and she does it flawlessly no cap.

---

✨ SYNOPSIS ✨

u32 rd32 (struct irdma_hw *hw , u32 reg );

two args, one u32 coming right back at you 💖

---

🦋 ARGUMENTS 🦋

• hw — the hardware info bundle, registers included 👑 think of it as the main character's whole vibe file
• reg — the register offset 🌈 i.e. which register we're peeking at

---

💜 DESCRIPTION 💜

returns the value of the register content, periodt. that's the whole plot 🍓
