NettetSysfs is a virtual file system that exports information about various kernel subsystems, hardware devices, and associated device drivers. The system passes information from the kernel space to the user space. Sysfs entries are either read-only (RO) or read-write (RW). For RW entries, sysfs can set values in the kernel space.
