2 Answers. When a system uses virtual memory, the kernel uses virtual memory as well. … This includes kernel code, data (or at least the data that is paged in — that’s right, Windows can page out portions of the kernel address space to the hard disk), and page tables. Each process has its own VM address space.
Does Linux use virtual memory?
Linux supports virtual memory, that is, using a disk as an extension of RAM so that the effective size of usable memory grows correspondingly. … The part of the hard disk that is used as virtual memory is called the swap space. Linux can use either a normal file in the filesystem or a separate partition for swap space.
How much memory does Linux kernel use?
A 32-bit processor can address a maximum of 4GB of memory. Linux kernels split the 4GB address space between user processes and the kernel; under the most common configuration, the first 3GB of the 32-bit range are given over to user space, and the kernel gets the final 1GB starting at 0xc0000000.
