This project is a technical reference and educational guide focused on the internal architecture of the Linux kernel. It serves as a low-level systems programming resource and documentation for operating system internals, detailing the implementation of core mechanisms within the kernel source code.
The materials provide a detailed study of the Linux kernel, tracing behavior through actual C source and assembly. It specifically covers the progression from the bootloader and decompression to the final kernel entry point, alongside the management of hardware interrupts and symmetric multiprocessing.
The content covers fundamental system architecture areas, including memory paging and resource control groups, process synchronization using primitives like spinlocks and read-copy-update, and the organization of kernel data structures such as radix trees and doubly linked lists. It also analyzes system call execution and the frameworks used for system time management.
The guide includes information on the kernel development workflow, covering the processes for compiling source code, linking binaries, and submitting patches.
