I'm new to Linux development. I have three processes P, TH_1, TH_2. The initial status of the system's and user's stack is the following:
I would like to indicate the current state of the processes given the initial state of the stack, specifying the event or the system call that led the process in the current state.
I should get that P is waiting for the completion of write, TH_1 is in mode U, TH_2 is ready for the expiration of the time quantum. However, I'm having a hard time understanding exactly why it is that.
Any kind of resource that could help me understand that would be very useful.
