いつのまにかcpupowerでtb情報表示がサポートされてる

cpupower frequency-info
Xeon E3-1260LでもTurbo Boostの情報表示されるようになってますね。

 boost state support:
analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0 1 2 3 4 5 6 7
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 10.0 us.
  hardware limits: 1.60 GHz - 2.40 GHz
  available frequency steps: 2.40 GHz, 2.40 GHz, 2.30 GHz, 2.20 GHz, 2.10 GHz, 2.00 GHz, 1.90 GHz, 1.80 GHz, 1.70 GHz, 1.60 GHz
  available cpufreq governors: conservative, userspace, powersave, ondemand, performance
  current policy: frequency should be within 1.60 GHz and 2.40 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 1.60 GHz (asserted by call to hardware).
  boost state support:
    Supported: yes
    Active: yes
    2500 MHz max turbo 4 active cores
    2800 MHz max turbo 3 active cores
    3200 MHz max turbo 2 active cores
    3300 MHz max turbo 1 active cores

こんな感じです
