  1. What: /sys/devices
  2. Date: February 2006

  4. Description:
  5. The /sys/devices tree contains a snapshot of the
  6. internal state of the kernel device tree. Devices will
  7. be added and removed dynamically as the machine runs,
  8. and between different kernel versions, the layout of the
  9. devices within this tree will change.
  10. Please do not rely on the format of this tree because of
  11. this. If a program wishes to find different things in
  12. the tree, please use the /sys/class structure and rely
  13. on the symlinks there to point to the proper location
  14. within the /sys/devices tree of the individual devices.
  15. Or rely on the uevent messages to notify programs of
  16. devices being added and removed from this tree to find
  17. the location of those devices.
  18. Note that sometimes not all devices along the directory
  19. chain will have emitted uevent messages, so userspace
  20. programs must be able to handle such occurrences.
