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.
