Such as title, process to the kernel stack only 8 KB, and process space there is 1 GB (32-bit systems), the kernel stack in where? Why do you say each process Shared the kernel stack?

CodePudding user response:

All the kernel stack process in kernel space (+ 3 g), each process has its own separate kernel stack, they share is the kernel address space (in kernel mode can use the kernel interface), because the quantity of process a lot, so that's why the kernel stack is small,
