Long duration power limit - this is the processor power consumption limit (in
Watts) during a long duration time window.
Long duration maintained - this is the time in milliseconds where the Long Dura-

Short duration power limit - During Turbo Mode, the system may exceed the
processor's default power setting and exceed the Short Duration Power limit. By
increasing this value, the processor can provide better performance for a short
duration.
