如何从 ISA 适配器获取/cat CPU Core Temp？

我正在 Linux 中构建一个脚本来监控我的活动核心温度；

然后，当 CORE 0 TEMP 达到 40 度时，手动启用 ACPI 风扇。

为了简单起见，我已经通过在 bash 终端中输入命令来构建按需工作的 fan 脚本，它被称为 fanon。

但是我想知道如何将这个 CORE 0 临时输出 CAT 到名为 gettemp 的 bash 脚本中的变量，该变量按间隔（例如每 2 秒）更新一次。

通过使用手表传感器，我在终端中得到以下输出。

acpitz-virtual-0
Adapter: Virtual device
temp1:        +45.0°C  (crit = +256.0°C)
temp2:        +36.0°C  (crit = +105.0°C)
temp3:        +32.0°C  (crit = +105.0°C)
temp4:        +24.1°C  (crit = +105.0°C)
temp5:       +100.0°C  (crit = +110.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +41.0°C  (crit = +100.0°C) <--- This is the temp I need!
Core 1:       +38.0°C  (crit = +100.0°C)

需要以某种方式找到 Core 0 Temp，以便我可以执行以下操作：

Core0Temp=$(cat /PATH/TO/ISA/TEMP/GOES/HERE)
Core1Temp=$(cat /PATH/TO/ISA/TEMP2/GOES/HERE)

然后我可以做

if [ $Core0Temp -gt "40" ]; then
echo "Exceeding Temp Value. Enabling Fan."
/var/tempmon/fanon
elif [ $Core0Temp -lt "40" ]; then
echo "Turning Fan Off."
/var/tempmon/fanoff
fi

如果有人想知道为什么我需要创建自己的散热机制，那只是因为我使用的是 Compaq NX-6310 商用笔记本电脑。

它（制造商）处理 ACPI 热事件的能力很差，并且与 ACPI 风扇的连接非常糟糕。谷歌上的许多搜索只向我展示了如何手动启用冷却系统。如下所示。

echo "Enabling ACPI FAN... "
echo 1 > /sys/class/thermal/cooling_device2/cur_state
echo "Fan Enabled... "

要禁用风扇，请通过 sudo 执行以下命令。

echo "Disabling ACPI FAN..."
echo 0 > /sys/class/thermal/cooling_device2/cur_state
echo "Fan Disabled..."

因此，我需要构建此脚本以使热芯片能够报告温度，并相应地启用风扇，就像您在任何沼泽标准笔记本电脑上所期望的那样。我只是找不到实际的核心温度位于哪里。手表传感器可以找到它们，但我找不到。

答案1

是的， ACPI 温度低于/sys/class/thermal，但lm_sensors硬件监控传感器低于/sys/class/hwmon/。

在我的系统上， 下有三个子目录/sys/class/hwmon/：hwmon0、hwmon1和hwmon2。就我而言，该coretemp模块恰好是hwmon1：在您的系统上这可能有所不同。您只需执行 即可识别每个子目录cat /sys/class/hwmon/hwmonN/name，其中 N 是数字。

coretemp我的系统上的温度值分别为/sys/class/hwmon/hwmon1/temp2_input和/sys/class/hwmon/hwmon1/temp3_input。这些文件名上的数字tempN_input也可能与您不同，具体取决于具体的 CPU 型号。这些值将是千分之一摄氏度的整数，即 41000 将是 41.0 摄氏度。

答案2

如果您安装了 sysfs（默认情况下应该如此），您可以在 中找到临时读数/sys/class/thermal/thermal_zoneX/temp。

在我的机器上，以下方法成功了

$ cat /sys/class/thermal/thermal_zone0/temp
27800
$ cat /sys/class/thermal/thermal_zone1/temp
29800
$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +27.8°C  (crit = +105.0°C)
temp2:        +29.8°C  (crit = +105.0°C)

答案3

11小时后..它还活着！

——ACPI Thermal CPU Superscript 的诞生。

我给它起了个名字，Tempmon！

我全都明白了。

  • 我想出了如何获得临时值...
  • 我把我的发现变成了上标......

对于这个脚本来说，这是一个巨大的编码会话......

几个小时的调试和测试，但它就像一个梦......

虽然还没有完全完成，但这里和那里做了一些调整，但是它有效，而且是连续的！

  • 它检查温度，
  • 根据核心 0 温度的读数打开和关闭 ACPI 风扇，

当它回到低温时...

  • 它会在同一进程内自动重新运行！
  • 对于 tput 和 setaf，$($tput $setaf $xwhite)，其颜色编码，但您可以删除这些标签并保持基本。

必须以 SUDO/ROOT 身​​份运行

我将把整个完成的脚本放在下面 - 由于它包含了如此多的命令，没有完整的东西，它不会满足我几个小时前提出的问题，如果没有完整的、完整的回答和解决我自己的问题，没有完整的代码！

此外，对于 HP 社区中的 Compaq NX-6310 商用笔记本电脑来说，此修复实际上是一个严重的错误修复！和其他人 - 也许，这种类型笔记本电脑的其他用户可能会发现这很有用，也许其他人也有类似的 ACPI 热问题，在 Linux Debian 9 中，ACPI 不会触发 ACPI 风扇本身......然后繁荣，过热 = 笔记本电脑冻结。
