With the good preparation in quarter term/bonding period, I have completed the generic cpuidle kernel module, native intel cpuidle module and cpuidle driver(for states/info reporting). By original plan, these tasks will be all completed by the end of 3⁄4 term… Well I want to show the power saving result on my laptop(i5-2520M CPU, 4G memory, 320GB harddisk), after enabling the cpuidle and native intel cpuidle module, I saved about 2.5watt. Note, such power saving is achieved after removing ipro1000 driver and disabling Tracker, Deskbar.
