Kernel 提示Package power limit notification 的解决方法

现象:

DELL 12G机型,Kernel 会报出以下提示,并会在控制台屏幕输出以下信息:

Apr 14 12:35:44 datacenter kernel: CPU1: Core power limit notification (total events = 308993)
Apr 14 12:35:44 datacenter kernel: CPU3: Core power limit notification (total events = 309097)
Apr 14 12:35:44 datacenter kernel: CPU5: Core power limit notification (total events = 309018)

给出的信息是 CPU 电源限制通知,这些并不是什么错误,当CPU处于低负载的时候,BIOS会控制CPU进行核心频率调节,或关闭某些核心和模块来达到省电的目的,这些功能源自于Intel C-State Tech 技术,AMD也有类似的省电技术。 继续阅读
