Populate the call array in usys.S for part a and part b.

Implement a tester for getpinfo() syscall in user/readingpstat.c. The output format is shown in the project description and video 3 in canvas has all the info you need.

Add tester that calls getpid() and a tester that prints the number of times that getpid() has been called.

Add tester that prints the number of system calls made by the user and the system.

Implement the function for part A by incrementing the counter. Add the ability to return the value for both part A and B.

Add all declarations for new syscalls (settickets() and getpinfo()) in necessary files. These files are listed in mini project 1.

Declare the function for the new system call in user/user.h

Register system calls for part A and part B in kernel/sysfunc.h

Update scheduler (in kernel/proc.c) from RR to lottery scheduler.

Add pointer to the new system call and then logic for counting the number of calls to the system call function

Implement tester in main() located at user/tickettest.c. Video 4 on canvas resources should have everything you need to do this.

Add syscall numbers for new syscalls created for Part A and Part B. This should be done in include/syscall.h

Add new programs to list of user programs in user/makefile.mk to be able to run tests.
