Generate a timeline showing each thread's state (ready, running, blocked on Sx/Mx, dormant, or interrupted) and each interrupt's state (dormant or running) following each event. Assume a non-preemptive system and that the scheduler is not run when a thread posts a semaphore or mutex, and the scheduler is not run when a thread is created. Priority inversions are not mitigated. a. Thread 3: Created at 10sec, runs for 20sec, pends S2, runs for 10sec, posts S1, runs for 10 sec Thread 2: Created at 0sec, runs for 30sec, pends S1, runs for 10sec Thread 1: Created at 0sec, runs for 20sec, posts S2, runs for 20sec
