rio_read_config_32(9) 💖 — Kernel API Manual ✨

okay so bestie, welcome to your rio_read_config_32(9) era. this is the Kernel API Manual page, and it is literally about grabbing 32 bits from configuration space. iconic behavior, no cap. 🎀

---

🌸 NAME 🌸

rio_read_config_32 — read 32 bits from configuration space 💅

---

✨ SYNOPSIS ✨

here is the exact signature, character for character, periodt:

int rio_read_config_32 (struct rio_dev *rdev , u32 offset , u32 * data
);

---

🫶 ARGUMENTS 🫶

• rdev — the RIO device, bestie. that's the device we're doing this whole read on. 🦋
• offset — offset into device configuration space. literally the spot inside config space where the read happens. 📍
• data — pointer to read data into. the read data goes here. 🎀

---

💖 DESCRIPTION 💖

Reads 32 bits of data from the specified offset within the RIO device's configuration space.

that's the whole vibe: 32 bits, specified offset, RIO device configuration space. it's giving “grab a 32-bit chunk from exactly where you asked” and honestly? slay. ✨🔥
