PintOS

PintOS is a simple operating system framework for the 80x86 architecture. It supports kernel threads, loading and running user programs, and a file system, but it implements all of these in a very simple way. In this project, we try to strengthen its support in all three of these areas, and also add a virtual memory implementation for it.

Here is a summary of the Project

Phase 1

• Wait Queue
• Basic Priority Scheduling

Phase 2

• User Program Exeuction
• Process Management
• System Calls

Phase 3

• Stack Growth
• Virtual Memory (Paging)
• Memory-Mapped Files

Phase 4

• Buffer Cache
• Extensible Files
• Filesystem and Subdirectories
