2025 Fall SKKU - Operating System class

Material: https://github.com/mit-pdos/xv6-riscv

• PA1: System call (getnice, setnice, ps, meminfo, waitpid)

• PA2: CPU scheduling (Linux EEVDF scheduler)

• PA3: Virtual memory (mmap, munmap, freemem, page fault handler)

• PA4: Page replacement (page swapping & LRU)

Completed

• System Calls: implemented getnice, setnice, ps, etc.
• CPU Scheduling: Linux EEVDF scheduler implementation.
• Virtual Memory: mmap, munmap, page fault handling.
• Page Replacement: LRU algorithm.
