如何在 Ubuntu 18.04 上监控 Ryzen 温度？

Question

我找到了这个帖子

https://linuxconfig.org/monitor-amd-ryzen-temperatures-in-linux-with-latest-kernel-modules

但是他们使用的 git 存储库不再存在，所以我无法尝试。

硬件：

@SERVER:~$ sudo sensors-detect
# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)
# Board: ASUSTeK COMPUTER INC. ROG STRIX X370-F GAMING
# Kernel: 4.15.0-38-generic x86_64
# Processor: AMD Ryzen 7 1800X Eight-Core Processor (23/1/1)

......

 Sorry, no sensors were detected.
Either your system has no sensors, or they are not supported, or
they are connected to an I2C or SMBus adapter that is not
supported. If you find out what chips are on your board, check
http://www.lm-sensors.org/wiki/Devices for driver status.

从 Linux 内核版本4.15（这是Ubuntu 18.04.1的默认值）开始，发行版中包含it87和nct6775模块。您不必自己编译它们。

这是it87现在的功能 - 在这个例子中AMD Ryzen 5 2600：

$ sensors
it8792-isa-0a60
Adapter: ISA adapter
in0:          +0.80 V  (min =  +0.00 V, max =  +2.78 V)
in1:          +1.02 V  (min =  +0.00 V, max =  +2.78 V)
in2:          +1.08 V  (min =  +0.00 V, max =  +2.78 V)
+3.3V:        +1.67 V  (min =  +0.00 V, max =  +2.78 V)
in4:          +1.30 V  (min =  +0.00 V, max =  +2.78 V)
in5:          +1.17 V  (min =  +0.00 V, max =  +2.78 V)
in6:          +2.78 V  (min =  +0.00 V, max =  +2.78 V)  ALARM
3VSB:         +1.67 V  (min =  +0.00 V, max =  +2.78 V)
Vbat:         +1.60 V  
fan1:           0 RPM  (min =    0 RPM)
fan2:           0 RPM  (min =    0 RPM)
fan3:           0 RPM  (min =    0 RPM)
temp1:        +30.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor
temp2:        +34.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = Intel PECI
temp3:        +34.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor
intrusion0:  ALARM

如果您需要每核温度和/或更好地支持AMD Zen 2 CPU，它们将在4.21 内核版本中可用- 希望在2019 年第一季度末。有关 Phoronix 的更多信息。

更新：4.21 刚刚随着5.0-rc1 版本变成了5.0
