rio_read_config_16(9)

🦋 NAME 🦋

okay bestie, welcome to the rio_read_config_16(9) page from the Kernel API Manual — and its whole vibe is: Read 16 bits from configuration space. no cap. 💖

---

✨ SYNOPSIS ✨

here’s the exact signature, bestie — do not touch the punctuation, she’s sensitive:

int rio_read_config_16 (struct rio_dev *rdev , u32 offset , u16 * data
       );

---

🎀 ARGUMENTS 🎀

• rdev — the RIO device. main character device energy. 👑
• offset — offset into device configuration space. yes, the exact spot. 🎯
• data — pointer to read data into. she receives the 16 bits. 🫶

---

💅 DESCRIPTION 💅

So like, rio_read_config_16 reads 16 bits of data from the specified offset within the RIO device’s configuration space. That’s the whole flex. It’s giving precise little read, and the offset tells it exactly where to look. ✨
