Modified XV6 by adding system calls and implementing different scheduling policies for my OS course

Implemented a modified version of Xv6's original scheduling algorithm and a modified priority-based scheduling algorithm to take both the waiting time and importance of a task into account
Added system calls to choose the scheduling algorithm in a process, to count the number of called system calls in a process, and several more features
Added the ability to measure creation time, termination time, sleeping time, ready time, and running time of processes to evaluate the performance of the new scheduling algorithms
