简而言之，我无法让 lm 传感器返回我的 CPU 温度。我在 Gigabyte GA-78LMT-USB3 主板上运行 Lubuntu 15.10（最新版）和 AMD 8350 CPU。我所做的以及输出：
安装：
sudo apt-get install lm-sensors
sudo sensors-detect
（参见：文章底部的输出）
已添加it87和coretemp至/etc/modules（重新启动，无济于事）
安装了以下内容（sudo make，sudo make install...）：
https://github.com/groeck/it87
有任何想法吗？

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):
Module cpuid loaded successfully.

VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... Yes
Found `ITE IT8620E Super IO Sensors' Success!
(address 0x228, driver `it87')

Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no):
Probing for `IPMI BMC KCS' at 0xca0... No
Probing for `IPMI BMC SMIC' at 0xca8... No
Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (yes/NO):
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Using driver `i2c-piix4' for device 0000:00:14.0: ATI Technologies Inc SB600/SB700/SB800 SMBus
Next adapter: Radeon i2c bit bus 0x90 (i2c-0)
Do you want to scan it? (yes/NO/selectively):
Next adapter: Radeon i2c bit bus 0x91 (i2c-1)
Do you want to scan it? (yes/NO/selectively):
Next adapter: Radeon i2c bit bus 0x92 (i2c-2)
Do you want to scan it? (yes/NO/selectively):
Next adapter: Radeon i2c bit bus 0x93 (i2c-3)
Do you want to scan it? (yes/NO/selectively):
Next adapter: Radeon i2c bit bus 0x14 (i2c-4)
Do you want to scan it? (yes/NO/selectively):
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `k10temp' (autoloaded):
* Chip `AMD Family 15h thermal sensors' (confidence: 9)
Driver `fam15h_power' (autoloaded):
* Chip `AMD Family 15h power sensors' (confidence: 9)
Driver `it87':
* ISA bus, address 0x228
Chip `ITE IT8620E Super IO Sensors' (confidence: 9)
To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
it87
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!
Do you want to add these lines automatically to /etc/modules? (yes/NO)
Unloading cpuid... OK
答案1
因此，您已经运行sudo sensors-detect并接受了它的默认值并允许它添加it87，coretemp但/etc/modules您却看不到 it87 芯片的输出。
如果您lsmod从终端运行，您会发现 coretemp 但 it87 不存在。
答案是编辑/etc/default/grub。您需要在行acpi_enforce_resources=lax尾添加GRUB_CMDLINE_LINUX。这是我的屏幕截图，其中突出显示了相关行。
然后sudo update-grub重新启动。
现在将出现 it87 传感器输出。然后您需要创建或找到主板的配置文件并将其插入/etc/sensors.d。
如果操作正确，这将为所有检测到的温度、电压和风扇速度赋予有意义的名称，丢弃任何未连接到任何设备的传感器的输出，设置合理的限制并使用分压电阻器计算感测到的电压值。以下是我使用 xsensors 的 it87 输出的屏幕截图。
答案2
temp3是您的 CPU 温度。Intel PECI是温度传感器和操作系统之间的桥梁。
