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