    5 You'll need to enable the following kernel options:
    6 
    7 CONFIG_NO_HZ
    8 CONFIG_HIGH_RES_TIMERS
    9 CONFIG_HPET_TIMER
   10 CONFIG_CPU_FREQ_GOV_ONDEMAND
   11 CONFIG_USB_SUSPEND
   12 CONFIG_SND_AC97_POWER_SAVE
   13 CONFIG_TIMER_STATS
   14 CONFIG_PERF_EVENTS
   15 CONFIG_PERF_COUNTERS
   16 CONFIG_TRACEPOINTS
   17 CONFIG_TRACING
   18 CONFIG_EVENT_POWER_TRACING_DEPRECATED
   19 CONFIG_X86_MSR
   20 ACPI_PROCFS_POWER
   21 CONFIG_DEBUG_FS
   22 
   23 And be sure to disable these:
   24 CONFIG_IRQBALANCE
   25 CONFIG_ACPI_DEBUG
   26 
   27 Not all of these are available on very recent kernels, so powertop
   28 might fail to display some stats.
