walk_central_bus(9)

🌸 NAME 🌸

okay so this is walk_central_bus(9), straight out of the Kernel API Manual — and the whole vibe is literally “find devices attached to the central bus.” 💖

It’s giving search-party energy for hardware. ✨

---

✨ SYNOPSIS ✨

void walk_central_bus (void );

---

🎀 ARGUMENTS 🎀

• void — no arguments. not a single one. not even a tiny little bestie. 🫶

---

🦋 DESCRIPTION 🦋

PDC doesn't tell us about all devices in the system. 😭

This routine finds devices connected to the central bus. So when PDC is lowkey leaving devices off the guest list, this is the function that goes looking. no cap. 🔥
