Composition of Linux system
Linux system is an open source and free multi-user, multi-tasking operating system , mainly used in servers, desktops and embedded systems. It consists of the following main components:
1. Kernel
The kernel is the core part of the Linux system and is responsible for managing hardware resources, process scheduling, memory management and file systems. . It acts as a bridge between all hardware and software components in the system.
2. System library
The system library contains a series of functions and routines for developing and running applications. They provide applications with the basic functionality they need to access system features and resources.
3. Shell
The shell is a command line interface that allows users to interact with the system. It processes commands entered by the user and performs corresponding operations. Common shells include Bash, Zsh, and Ksh.
4. File System
A file system is a hierarchy of files and directories used to organize and store data. It provides mechanisms to access, manage and protect files. Linux systems support a variety of file systems, including EXT4, XFS and btrfs.
5. Desktop Environment
The desktop environment provides users with a graphical user interface (GUI) that allows them to interact with the system in an intuitive manner. It includes a window manager, file browser, application launcher, and other basic features. Popular desktop environments include GNOME, KDE and XFCE.
6. Application software
Application software are programs that users use to perform specific tasks, such as word processing, spreadsheets, and web browsing. Linux systems provide a wide range of application software, from basic utilities to advanced development tools.
7. Documentation
Documentation is crucial to understanding and using the Linux system. It includes man pages, online help, and tutorials that provide detailed information on commands, configuration options, and troubleshooting.

To make Linux processes run in real-time FIFO scheduling, you need to use the chrt command or sched_setscheduler system call to set the scheduling policy and priority, such as sudochrt-f99./app or configure SCHED_FIFO and priority parameters in the C program, and ensure that the process has CAP_SYS_NICE capability or root permissions, and configure rtprio and memlock restrictions through limits.conf to ensure real-timeness and avoid priority reversal. You need to use a mutex that supports priority inheritance.

According to user feedback, the current system name no longer displays the "NEXT" suffix, and it is officially renamed to HarmonyOS6.0. Huawei initially proposed the name HarmonyOSNEXT for the first time at the developer conference in August 2023, aiming to mark the Hongmeng system entering a new stage of development and realizing true native self-development. HarmonyOSNEXT's most core breakthrough is to completely adopt the underlying system architecture developed independently, completely remove the Linux kernel and Android AOSP code, and only run applications based on the HarmonyOS kernel.
