Exercises M1 and M2

• M1: Using the test and set lock (TSL) instruction, modify the "busy-waiting" semaphores presented in class so that mutual exclusion of the semaphore counter "s" is guaranteed.

• M2: Mutual exclusion with the TSL instruction as described in class does not guarantee bounded waiting. Find a solution to the critical section problem using the TSL instruction that guarantees bounded waiting. That is, find a solution that guarantees that given N processes, a processes is bypassed no more than N-1 times before it enters the critical section.
