/proc/kcore size doesn't match with physical ram size
I recently install slackware linux 10 with default setting into my pc which has 4GB physical ram. Right after installation and first reboot, i noticed that the size of /proc/kcore is 907MB but not 4GB. People always said /proc/kcore is an alias to the physical ram. Thus, where is all my ram gone?
I need to copy the whole content of ram into file so that i can do some analysis on it. Can anyone teach me how?
