Question

Suppose we have a system with 50 active processes, P0, P1, ..., P49, some user processes, and some kernel processes. For simplicity, we are not concerned with threads in this question. Ready processes are scheduled to Run by some scheduler. The scheduling algorithm does not matter here. Suppose process P13 makes a disk_read() operating system call. Assume that completion of disk transfer is signaled by an interrupt from the disk controller. Trace as accurately as you can what happens in the CPU (not the disk) until process P13 has received its requested information from the disk.

Hints:

The question is about interrupt handling
I am looking for a trace of what processes run, why, and what they do.
I am not looking for instruction-level explanations.
I am not looking for a discussion of disk access, operation, or transfer.
