lm sensores não retornam temperatura da CPU (it87)

Question

Olá a todos (desculpas pela formatação, abaixo),

Simplificando, não consigo fazer com que os sensores de lm retornem minha temperatura da CPU. Estou executando o Lubuntu 15.10 (atualizado) com um processador AMD 8350 em uma placa-mãe Gigabyte GA-78LMT-USB3. O que eu fiz e a saída:

Instalação:

sudo apt-get install lm-sensors
sudo sensors-detect

(veja: saída na parte inferior do post)

Adicionada it87 e coretemp a /etc/modules (reinicializada, sem sucesso)

Instalado o seguinte ( sudo make , sudo make install ...): link

Alguma idéia?

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):

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

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

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):

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

    

Answer 1

Então, você executou sudo sensors-detect aceitou seus padrões e permitiu que ele adicionasse it87 e coretemp a /etc/modules , mas você não vê as saídas do chip it87.

Se você executar lsmod de um terminal, encontrará o coretemp, mas it87 não está lá.

A resposta é editar /etc/default/grub . Você precisa anexar acpi_enforce_resources=lax no final da linha GRUB_CMDLINE_LINUX . Aqui está uma captura de tela da minha com a linha relevante destacada.

Em seguida, sudo update-grub seguido de uma reinicialização.

As saídas do sensor it87 aparecerão agora. Você precisará então criar ou encontrar um arquivo de configuração para sua placa-mãe e inseri-lo em /etc/sensors.d .

Se feito corretamente, isso dará nomes significativos a todas as temperaturas, tensões e velocidades de ventilador detectadas, descartará as saídas de qualquer sensor não conectado a qualquer coisa, estabelecerá limites razoáveis e calculará os valores das tensões detectadas usando resistores divisores de tensão. Aqui está uma captura de tela das minhas saídas it87 usando xsensors.

    

Answer 2

temp3 é a temperatura da sua CPU. Intel PECI é a ponte entre os sensores de temperatura e o SO.
