sensors只有核心温度?但是BIOS有CPU TM function 选项,难道是摆设?还是根据核心温度判断?

代码： 全选

$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +38.0°C  (high = +76.0°C, crit = +100.0°C)
Core 1:       +30.0°C  (high = +76.0°C, crit = +100.0°C)

你想让它显示什么？你觉得TM function 是个什么东西？

Chapter 13, INTEL IA-32-3A Manual:
13.5.2.2 Thermal Monitor 2
An additional automatic thermal protection mechanism, called Thermal Monitor 2 (TM2), was introduced in the Intel Pentium M processor and also incorporated in newer models of the Pentium 4 processor family. Intel Core Duo and Solo processors, and Intel Core 2 Duo processor family all support TM1 and TM2. TM2 controls the core temperature of the processor by reducing the operating frequency and voltage of the processor and offers a higher performance level for a given level of power reduction than TM1.
TM2 is triggered by the same temperature sensor as TM1. The mechanism to enable TM2 may be implemented differently across various IA-32 processor families with different CPUID signatures in the family encoding value, but will be uniform within an IA-32 processor family.
Support for TM2 is indicated by CPUID.1:ECX.TM2[bit 8] = 1.
