Hello, Can sombody tell me how the first column of /proc/<pid>/statm is defined? That's SIZE or VIRT in "top". It is always less or equal VmSize. SIZE seems to be the amount of virtual memory that is resident in either main memory (= column RES) or swap. But this can't be true in every case, because I can easily create processes that have a greater SIZE than the total main memory (without using any swap). I tried to mmap a 1GB area of /dev/mem with linux-2.4.21 and accessed the lower 500MB. The SIZE of the process went up to 950MB, no swapping - with a total main memory of 512MB. After some experimentation with mmap-ing /dev/mem, the kernel got a brain-damage and crashed several times in the mm-code, so I'm not sure if I have a clue what I'm doing. :-) Thanks, Thomas. -- Kernelnewbies: Help each other learn about the Linux kernel.
