In computing, a devicetree (also written device tree) is a data structure describing the hardware components of a particular computer so that the operating system's kernel can use and manage those components, including the CPU or CPUs, the memory, the buses and the integrated peripherals.
udev (userspace /dev) is a device manager for the Linux kernel.As the successor of devfsd and hotplug, udev primarily manages device nodes in the /dev directory. At the same time, udev also handles all user space events raised when hardware devices are added into the system or removed from it, including firmware loading as required by certain devices.
The Linux Device List was created in 1992 by Rick Miller, and maintained by him until 1993. In 1995, it was adopted by H. Peter Anvin. In 2000, he created LANANA to maintain the list and other similar lists in the future. The name of the registry was a playful reference to IANA, the central registry of names and numbers used in the Internet.
Linux distributions that have highly modified kernels — for example, real-time computing kernels — should be listed separately. There are also a wide variety of minor BSD operating systems, many of which can be found at comparison of BSD operating systems .
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices. It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots .
Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, [20] whereas many traditional Unix-like operating systems use /sys as a symbolic link to the kernel source tree.
Sysfs was designed to export the information present in the device tree which would then no longer clutter up procfs. It was written by Patrick Mochel. It was written by Patrick Mochel. [ 3 ] [ 4 ] Maneesh Soni later wrote the sysfs backing store patch to reduce memory usage on large systems.
The Linux console is a system console internal to the Linux kernel. A system console is the device which receives all kernel messages and warnings and which allows logins in single user mode. [1] The Linux console provides a way for the kernel and other processes to send text output to the user, and to receive text input from the user.
