What: /sys/devices

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.
