Stack Setup in Operating Systems

[ekanth]

I'm on the way developing my own OS. How should I setup stack in an Operating System? If an user process is to be initiated should I know it should have a separate stack from the kernel's one. But the thing is that should I need to have different stack between user processes. If so what could be the optimal size of the stack? I dont know whether I am clear this time. If not please inform.
Please Help.
Ekanth Treat the daily build of a project as the heartbeat of the project. If there's no heartbeat the project is dead.

Any modern computer OS will have separate stacks (and address spaces) for each process. The kernel should execute in its own address space and run in processor supervisor/privileged mode. Additionally you should implement your design using virtual memory, allowing any process's stack (or heap) to grow arbitrarily.

Mark.
