Understanding Linux Architecture and Boot Process with Diagrams
This article presents a collection of diagrams that illustrate the Linux system architecture, the SCI module interface framework, device driver placement, and the complete boot sequence from the firmware bootloader through the kernel to the system layer.
1. Linux System Architecture Diagram
The diagram outlines the overall structure of a Linux system, showing the relationship between hardware, kernel space, and user space components.
1.1 SCI Module System Interface Framework
This diagram depicts the call framework used by the SCI (System Call Interface) module within the kernel.
1.2 Device Driver
The illustration shows where device drivers fit into the Linux architecture.
2. Linux Boot Process Diagram
This diagram provides an overview of the entire boot sequence.
2.1 Bootloader Layer
Shows the initial stage where firmware loads the bootloader.
2.2 Kernel Layer
Depicts the kernel initialization after the bootloader hands control.
2.3 System Layer
Illustrates the final stage where user-space services start and the system becomes operational.
