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. | |
