sys_bus(5)

💖 sys_bus(5) — the /sys/bus/ page, bestie edition 💖

okay so this is a page from the File Formats Manual, and it's literally just about one directory: /sys/bus/. that's it. that's the whole vibe. let's get into it 🦋

✨ NAME ✨

/sys/bus/ — system buses 🌈

🎀 SYNOPSIS 🎀

/sys/bus/

👑 DESCRIPTION 👑

bestie. this directory is the main character of bus land. it contains one subdirectory for each of the bus types in the kernel. every bus type, its own little folder, no cap. 💅

and inside each of those directories? not one but two subdirectories. two. a duo. iconic behavior:

• devices — this subdirectory contains symbolic links to entries in /sys/devices that correspond to the devices discovered on this bus. so like, the devices that got found on this bus? their symlinks live here, pointing back at /sys/devices. it's giving soft links doing the lord's work 🔥
• drivers — this subdirectory contains one subdirectory for each device driver that is loaded on this bus. every loaded driver gets its own subdirectory, one each, no sharing, no merging, we don't do that here 💖

fr fr, the structure is: bus type → devices + drivers. two subdirectories per bus. that's the tea. 🍓

⭐ STANDARDS ⭐

Linux. that's it. that's the standard. 🐧

🌸 HISTORY 🌸

Linux 2.6.0. an oldie but a goodie, been holding it down since way back. ⭐
