• This work includes the implementation of synchronization in Linux kernel.

  • I implemented the Barrier through three system calls.

  • barrier_init(int count, unsigned int* barrier_id)

  • barrier_wait(int barrier_id)

  • barrier_destroy(int barrier_id)

  • For efficient development and quick debugging, I also provide a driver module (04_barrier_driver_module) in same logic of this synchronzation.

  • For system call and driver module, I also support testing programs.
