processor.max_cstate
--------------------------------------------------------
processor.max_cstate — Limit the processor to a maximum C-state.
Synopsis

processor.max_cstate= n
Description

Limit the processor to a maximum C-state, no matter what the ACPI tables say it can support. n is a valid C-state value. A value of 9 overrides any DMI blacklist limit that might be present for this processor.

ACPI就是Advanced Configuration and Power Interface的缩写,意思是“高级配置与电源接口”。这是英特尔、微软和东芝共同开发的一种电源管理标准。
