  • If you surprised why it has a PowerPC CPU. It’s actually a SoC.
    From the manual:

    AMCC PowerPC 405 32-bit RISC processor core operating up to 333MHz with 16KB D-and I-caches.

    Designed specifically to address embedded applications, the PowerPC 405EP (PPC405EP), provides a high-performance, low-power solution that interfaces to a wide range of peripherals by incorporating on-chip power management features and lower power dissipation requirements.

    TLP can also control CPU clock.

    I’m using these settings on my trusty X260:

    CPU_SCALING_GOVERNOR_ON_AC=performance
    CPU_SCALING_GOVERNOR_ON_BAT=powersave
    
    CPU_MIN_PERF_ON_AC=0
    CPU_MAX_PERF_ON_AC=100
    
    CPU_MIN_PERF_ON_BAT=0
    CPU_MAX_PERF_ON_BAT=30
    
    CPU_BOOST_ON_AC=1
    CPU_BOOST_ON_BAT=0
    
    CPU_HWP_DYN_BOOST_ON_AC=1
    CPU_HWP_DYN_BOOST_ON_BAT=0
    
    SCHED_POWERSAVE_ON_AC=0
    SCHED_POWERSAVE_ON_BAT=1
    
    USB_EXCLUDE_WWAN=1
