  10           This adds a CPUFreq driver which uses CPPC methods
  11           as described in the ACPIv5.1 spec. CPPC stands for
  12           Collaborative Processor Performance Controls. It
  13           is based on an abstract continuous scale of CPU
  14           performance values which allows the remote power
  15           processor to flexibly optimize for power and
  16           performance. CPPC relies on power management firmware
