Hello What exactly is the difference between /dev/mem and /dev/kmem. While looking at the source code in char/mem.c I noticed that the mmap function for both are the same. I believe that /dev/mem is the actual physical memory mapping. What is /dev/kmem used for? Thanks S -- Kernelnewbies: Help each other learn about the Linux kernel.
