'Does there exist Kernel stack for each process ?
Does there exist a Kernel stack and a user-space stack for each user space process? If both stacks exist, there should be 2 stack pointers for each user space process right?
Solution 1:[1]
Each user space thread(not just process) has its user space stack and kernel space stack. The kernel space has one stack percpu and the ISR has its seperate stack too.
