Can you list the properties of the idle states in this configuration, that is: $ grep -r '.*' /sys/devices/system/cpu/cpu0/cpuidle/state1/ and analogously for state2 and state3, and send the output of this? On my desktop system the above comment produces the following output: /sys/devices/system/cpu/cpu0/cpuidle/state1/disable:0 /sys/devices/system/cpu/cpu0/cpuidle/state1/above:1022634 /sys/devices/system/cpu/cpu0/cpuidle/state1/time:2556533185 /sys/devices/system/cpu/cpu0/cpuidle/state1/power:0 /sys/devices/system/cpu/cpu0/cpuidle/state1/residency:2 /sys/devices/system/cpu/cpu0/cpuidle/state1/latency:2 /sys/devices/system/cpu/cpu0/cpuidle/state1/usage:17625391 /sys/devices/system/cpu/cpu0/cpuidle/state1/desc:MWAIT 0x00 /sys/devices/system/cpu/cpu0/cpuidle/state1/below:6578613 /sys/devices/system/cpu/cpu0/cpuidle/state1/default_status:enabled /sys/devices/system/cpu/cpu0/cpuidle/state1/name:C1 /sys/devices/system/cpu/cpu0/cpuidle/state1/s2idle/time:0 /sys/devices/system/cpu/cpu0/cpuidle/state1/s2idle/usage:0 Thanks!
