3/7/2023 0 Comments Kernel stack size* in kernel mode (after switching to kernel mode by ), portion of the process (code areas),its addresses and core kernel data, starts to use the kernel stack. Shortly, linux process can operates in two modes:Īny process which runs the in user mode refers to private(own) stack area that is used for holds local variables,parameters,frame pointer(very useful while detect relative addres of any func local variables after pushes,pops especially in debug processing),temporary(as a cpy) values(like in c,c++,java),return address from funcs and automatic variables within functions. Means in Linux each process has a user mode stack and a corresponding Kernel mode stack? So, there is two stacks per process?Īctually they are used on the separate modes.Īnd in this state lets we split to as modes(user/kernel) for better understanding of its.
