10 help
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.
