There are also /dev/mem and /dev/kmem: mem(7) mem(7) NAME mem - main memory DESCRIPTION mem is a special file that is an image of the main memory of the computer. It may be used, for example, to examine and patch the system. Byte addresses in mem are interpreted as physical memory addresses. References to non-existent locations cause errors to be returned. File kmem is the same as mem except that kernel virtual memory rather than physical memory is accessed. Please refer to kmem(7) for information about ioctl operations that are supported on /dev/kmem. ... NAME kmem - perform I/O on kernel memory based on symbol name.
