Hi all,
I have a very basic doubts about kernel space and user space.
1. Is the kernel space is limited or not if it limited what is the limit.
Yes, there is a limit to the virtual address space of the kernel. This
is generally 1 GB, but can be configured at the compile time (kernel
configurarion).
2. If the kernel space is limited how the kernel manages the processes
kernel stack and other kernel memory requirements.
The kernel has to stay in this limit. However, if required it can
temporarily map (kmap) other memory into its own virtual address
space.
3. is kernel space data can be swaped to swapspce .
No.
