System Documentation

What problem does it solve?

This Skill provides a comprehensive reference for implementing multitasking in OS kernels, covering process management, context switching, ring transitions, and scheduler design to help developers build robust, preemptive multitasking systems.

Core Features & Use Cases

  • Task structures and scheduling data: task control blocks, per-task kernel stacks, and essential state tracking for preemption.
  • Context switch and interrupt flow: saving/restoring CPU state, CR3 handling, TSS.RSP0 updates, and safe transitions between user and kernel modes.
  • System call and ring transitions: mechanisms for moving between rings, including SYSCALL/SYSRET and legacy paths, with attention to safe kernel entry.
  • Scheduler policies: Round Robin, Priority, Multilevel Feedback Queue, and O(1) scheduling variants with guidance on when to apply each.
  • Practical use: supports kernel developers implementing multitasking in new OS projects, with best practices and pitfalls.

Quick Start

Begin by studying task management concepts and implement a basic Round Robin scheduler in your kernel.
