What: /sys/devices
|
||||
Date: February 2006

Contact: Greg Kroah-Hartman <gregkh@suse.de>
|

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