OS161 Kernel hacking.

Hack on OS161 Kernel to implement synchronization primitives, System calls and Process support and Virtual memory subsystem.

  • ASST1: Synchronization : branch

    • Implement locks, condition variables and reader-writer locks. Next, use them to solve a few synchronization problems.
  • ASST2: System Calls and Process Support : branch

    • Implement the system call interface.
    • File system support: open, read, write, lseek, close, dup2, chdir, and __getcwd.
    • Process support: getpid, fork, execv, waitpid, and _exit.
  • ASST3: Virtual Memory : branch-3-1, branch-3-2

    • A large amount of code to implement and many internal interfaces to design.
    • Implement virtual memory, including address translation, TLB management, page replacement and swapping.
