1What: /sys/devices2Date: February 20063Contact: Greg Kroah-Hartman <gregkh@linuxfoundation.org>4Description:5 The /sys/devices tree contains a snapshot of the6 internal state of the kernel device tree. Devices will7 be added and removed dynamically as the machine runs,8 and between different kernel versions, the layout of the9 devices within this tree will change.10 11 Please do not rely on the format of this tree because of12 this. If a program wishes to find different things in13 the tree, please use the /sys/class structure and rely14 on the symlinks there to point to the proper location15 within the /sys/devices tree of the individual devices.16 Or rely on the uevent messages to notify programs of17 devices being added and removed from this tree to find18 the location of those devices.19 20 Note that sometimes not all devices along the directory21 chain will have emitted uevent messages, so userspace22 programs must be able to handle such occurrences.23 24Users:25 udev <linux-hotplug-devel@lists.sourceforge.net>26
