🧭 Course Title: XV6 Operating System Kernel Design from Scratch in C 🚀 GroupLayout: Practical Hands-On Design of the XV6 Operating System Kernel

📚 Course Description:

Are you ready to dive into the world of operating systems and their inner workings? Our comprehensive, 8-hour course, "XV6 Operating System Kernel Design from Scratch in C", will guide you through the process of designing your very own lightweight kernel. This course is tailored for those eager to understand the core concepts of operating systems by building one from the ground up using the C programming language.

What You'll Learn:

• Initialization of Kernel Subsystems:

  • Process management
  • Memory initialization
  • Disk operations
  • Interrupt and trap handling
  • Mode switching (machine, supervisor, user)

• Kernel Operating Modes Explained:

  • Understanding the importance of each mode
  • Switching mechanisms between modes for efficient operation

• Concurrency Control with Locks:

  • Implementing spin locks and sleep locks to ensure data integrity in multi-core environments

• Hardware Virtualization Techniques:

  • Integrating external hardware like keyboards and displays using the 16550A UART chip
  • Ensuring seamless interaction with virtualized devices

• Virtual Memory Addressing:

  • Mapping virtual addresses to physical memory space

• System Calls Creation and Execution:

  • Initiating system calls from user mode
  • Transitioning to and executing in supervisor mode

• Time-based Operations Management:

  • Understanding sleep() functions and scheduler mechanisms
  • Managing timed operations using timer interrupts

• Disk Management Strategies:

  • Implementing buffering, bit-mapping, and logging techniques

• Hardware Virtualization for Disk Access:

  • Enabling disk access from a virtual machine to the host system using VIRTIO memory-mapped registers

• File Systems Management:

  • Handling file systems through inodes, pipes, and device files on disk and in memory

• Process Management Techniques:

  • Learning process creation, allocation, manipulation, and scheduling strategies

By the end of this course, you will have a solid understanding of how an operating system functions at its core. You'll gain hands-on experience with one of the most popular educational kernels—XV6—and learn to implement your own version using C. Whether you're a student, educator, or hobbyist, this course will equip you with the knowledge and skills needed to tackle complex operating system concepts and designs.
