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
17 support for its operation.
