ARM/N900/Performance/bootup memory usage script

3 steps for collecting memory usage data automatically after boot

• Install sp-smaps
  • wget http://repo.pub.meego.com/home:/timoph/Project_DE_Trunk_Testing_standard/armv7hl/sp-smaps-0.3.0-3.2.DE.armv7hl.rpm
  • rpm -Uvh sp-smaps-0.3.0-3.2.DE.armv7hl.rpm
• Copy/Paste from below the /usr/bin/memusage.sh script to Meego (remember to do: chmod a+x /usr/bin/memusage.sh)
• Launch /usr/bin/memusage.sh from /etc/rc.sysinit
• Reboot --> Data should be available after 120 sec in /home/meego/memusage dir
  • html file for smaps findings
  • txt file for data generated by other mem tools
    • Especially "ps -e -orss=,args= | sort -b -k1,1n | pr -TW100" data from top memory usager processes is interesting
