So the basic idea as much as much I can interpret is what all can result if use machine instructions for implementing mutual exclusion like deadlock is a problem , starvation and busy waiting .. 2 votes 2 votes gauravkc commented Nov 28, 2018 reply Follow Share Oh yes. Sleep and wakeup are machine instructions. Got confused between machine instructions and hardware implementations. 0 votes 0 votes Please log in or register to add a comment.
