Linux 内核配置

启用电源管理的最小化内核设置

要在 Linux 内核中启用适当的电源管理功能，请启用以下设置：

KERNEL Minimum kernel setup for Power Management

Power management and ACPI options --->
  -*- Device power management core functionality
  [*] ACPI (Advanced Configuration and Power Interface) Support --->
    <*> AC Adapter
    <*> Battery
    -*- Button
    -*- Video
    <*> Fan
    <*> Processor
    <*> Thermal Zone
  
  [*] CPU Frequency scaling --->
        Default CPUFreq governor (ondemand)  --->
    -*- 'performance' governor
    <*> 'powersave' governor
    <*> 'userspace' governor for userspace frequency scaling
    -*- 'ondemand' cpufreq policy governor
    <*> 'conservative' cpufreq governor
    <*> ACPI Processor P-States driver

Do not forget to enable the CPU frequency scaling driver for the CPU. For the SandyBridge and higher Intel core series of processors, userspace , ondemand , and conservative governors are unnecessary; performance should be selected as the default, and Intel P state control should be selected instead of ACPI Processor P-States driver . ^[1]^

In this case, the userspace , ondemand , and conservative governors are unnecessary. The performance governor should be selected as the default. ^[2]^

Enabling additional drivers

For Intel processors used in laptops since 2011 you may want to enable additional advanced features - Thermal and powercap sysfs.

Thermal sysfs driver

powercap sysfs driver

Additionally, you can enable Running Average Power Limit – RAPL technology. Both PowerTOP and turbostat utilities are aware of RAPL. For RAPL enablement use:

KERNEL Generic powercap sysfs driver

Device Drivers --->
  [*] Generic powercap sysfs driver --->
       Intel RAPL Support

内核中帮助项有的找不到位置， 可能很久没更新了 里面的选项可以导出来么？怎么导出？知道的说一声，就是导出如上图树形结构的
