LINSYSFS(5)

📦 version 14.5, in freebsd 14.5

✨ NAME ✨

Okay so bestie, this is linsysfs — the Linux kernel objects file system. It's giving major compatibility vibes, and we're about to break it down so you get it. 💖

🦋 SYNOPSIS 🦋

linsysfs                /compat/linux/sys       linsysfs        rw 0 0

🌸 DESCRIPTION 🌸

The Linux system file system, or linsysfs, emulates a subset of the Linux sys file system and is required for the complete operation of some Linux binaries. No cap, if you're running Linux stuff, you probably need this. 🫶

The linsysfs provides a two-level view of devices. At the highest level, PCI devices themselves are named, according to their bus, slot and function in the system hierarchy. PCI storage devices are listed in the scsi_host class with a device symlink to the PCI directories of the devices. It's giving organized, fr fr. 🎀

Each device node is a directory containing some files and directories:

  • host — A place holder for storage host information. Yes bestie, it's just a placeholder, don't @ me. 🙈
  • pci_id — A directory for the pci_id that contains either the device information or another directory structure for a PCI bridge. It's giving nested vibes. 🌈

Each host node of scsi_host is a directory containing some files and directories:

  • proc_name — The Linux registered driver name for these devices. Iconic. 👑
  • device — A symlink to the PCI device directory. Slay. 💅

🧚 FILES 🧚

  • /compat/linux/sys — The normal mount point for linsysfs. Your main character location. ⭐
  • /compat/linux/sys/class/scsi_host — The storage host node. Lowkey important. 🍓
  • /compat/linux/sys/devices/pci0000:00 — The PCI device hierarchy node. It's giving hierarchy. 💜

🔥 EXAMPLES 🔥

The most common usage follows:

mount -t linsysfs linsysfs /compat/linux/sys

where /compat/linux/sys is a mount point. Obsessed with how simple that is. 😭

👑 HISTORY 👑

The linsysfs driver first appeared in FreeBSD 6.2. It's giving vintage but make it modern. 🔥

💖 AUTHORS 💖

The linsysfs driver was derived from linprocfs by Doug Ambrisko. This manual page was edited by Doug Ambrisko, based on the linprocfs(5) manual page by Garrett Wollman. King behavior, periodt. 🫶

And that's the vibe check, bestie. This page came from Debian, November 13, 2019, LINSYSFS(5) — now go mount some stuff. 💅✨
