Hi group, I have a couple of questions on stack usage. would appreciate if anyone could help me in answering these questions. * What is the stack used by modules to execute ? * Is it always the case that Interrupt handlers use the kernel mode stack of the process that was in execution when the interrupt occurred ? What about the case when the control was in kernel when the interrupt is received ? * Also is it always the case that ebp register stores the address of the current user mode stack frame ?
