I wrote this tool to get nicer memory reports. It takes a while to understand the numbers... depending on the kernel version, you may need to adjust the code though. Feel free to try it. It needs swap to build *in* the nanonote, but you should be able to cross-build it easily. It needs some special kernel parameters enabled; I don't know if your kernel will have them. http://vicerveza.homeunix.net/~viric/cgi-bin/memstat/index Regards, Lluís. _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
