8.1. Processor Power States — ACPI Specification 6.4 documentation

C-States：英文為CPU States的縮寫，中文為處理器狀態。 正常運作靠P-States. P-States 指的就是CPU 處理器依據目前運算量負荷輕重，調整運作頻率的 ...

C-States从C0开始，C0是CPU的正常工作模式，CPU处于100%运行状态。C后的数越高，CPU睡眠得越深，CPU的功耗被降低得越多，同时需要更多的时间回到C0模式。

C-States range from C0 to Cn. C0 indicates an active state. All other C-states (C1-Cn) represent idle sleep states where the processor clock is inactive (cannot ...

C-state用於控制CPU在不活動時可以進入的休眠層級，它從C0開始編號（CPU處於正常工作狀態），一直到C6（最深的休眠層級，此時CPU進入低功耗狀態）。

Processor power states include are designated C0, C1, C2, C3, ...Cn. The C0 power state is an active power state where the CPU executes instructions.

Description: Modern CPUs utilize a technology called C-States to manage the amount of power that individual processor cores are utilizing.

Package C-States. The processor supports C0, C2, C3, C6, C8, and C10 package states. The following is a summary of the general rules for ...

为了在CPU空闲时节约能源，可以让CPU进入低功耗模式。C-state是intel CPU处于空闲时的一种状态，CPU有几种电源模式，它们统称为“c状态”或c模式。CPU的每个 ...

It is a global setting of all CPU cores depending on the value you write the allowed states are different. It is practical to use when no CPU pinning is used.
