Info
 The Sys-Filesystem, short sysfs, is a virtual filesystem extension located at /sys. It provides realtime information about numerous kernel objects. This covers Linux-Devices, Kernel-Modules, Linux-Filesystems, and other kernel components.

For more details see the sysfs(5) man page.

Daily updated index of all sysfs objects found scanning Supportdata2 probes. Last update: 2023-12-08 05:20 GMT.
The label (sysfs) in the Object column shows there are other objects in this wiki using this name.
The Mod column shows the amount of models using the respective objects. Click the column header to sort by this number.
Kernel also shows the access permissions r = read, w = write and l = inherit from link target.
This only covers files and links in selected /sys subfolders. Like every other section this will grow with time.
