Linux API, Linux ABI, and in-kernel APIs and ABIs. The Linux kernel provides multiple interfaces to user-space and kernel-mode code that are used for varying purposes and that have varying properties by design. There are two types of application programming interface (API) in the Linux kernel: the "kernel–user space" API; and; the "kernel ...
Like pipes, pseudoterminals have a limited capacity. On Linux, the pseudoterminal capacity is about 4 KiB in each direction. A typical Linux kernel-based operating system provides many PTYs to support text-based interfaces as provided by terminal emulators (such as xterm or gnome-terminal) and remote access interfaces like SSH.

The Linux console (and Linux virtual consoles) are implemented by the VT (virtual terminal) subsystem of the Linux kernel, and do not rely on any user space software. [3] This is in contrast to a terminal emulator , which is a user space process that emulates a terminal, and is typically used in a graphical display environment.
The role of KMS (Kernel mode-setting), Linux example Wayland compositors require KMS (and also OpenGL ES and EGL ) evdev was the Linux kernel module that receives data from various Input devices such as Keyboard, Mouse, Touch-Pad, etc. Nowadays, this is the libinput module (for X and Wayland).
The Linux kernel is a free and open source, [11]: 4 Unix-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free replacement for Unix.
Navigate through the kernel features and menuconfig commands. Esc+Esc: Exit menuconfig or cancel the command. ↵ Enter: Activate a command, or expand a branch. y: Compile and include this feature inside of the kernel. m: Compile this feature as a module, separate from the kernel. n: Do not compile the feature. / Search configuration parameter.
Simplified structure of the Linux kernel: ext4 is implemented between the Linux kernel Virtual File System and the generic block layer. Linux kernel Virtual File System is a subsystem or layer inside of the Linux kernel. It is the result of an attempt to integrate multiple file systems into an orderly single structure.
