Após instalar com sucesso lm-sensors no meu Turnkey Linux , eu chamei sensors-detect . Infelizmente, informa que não é possível detectar nenhum sensor . Eu tentei o script de 2010 que vem com a minha distro Turnkey, também eu baixei o atual.
Eu corro um kernel Linux 2.6.32-5-686 em um bom e velho Dell D400 Latitude - um "Intel Pentium M 1.8GHz" dentro (família 6, modelo 13, passo 6) , como dito por /proc/cpuinfo . Eu reúno que coretemp seria o driver de escolha.
Parece que o ponto chave é que o módulo do kernel coretemp não é fint e dispositivos. Se eu executar modprobe coretemp , diz
FATAL: error inserting coretemp (.../coretemp.ko): No such device
O que "dispositivo" significa? Este é o driver correto?
Eu obtenho alguns em /proc/acpi/thermal_zone/THM/temperature . Mas eu suspeito que seja falso, ele sempre mostra 46 ° C. Atualmente, ele mostra valores entre 46 ° C e 47 ° C.
Também /proc/acpi/processor/CPU0/ contém informações, desta vez parece útil. Por exemplo cat info
processor id: 0
acpi id: 0
bus master control: yes
power management: yes
throttling control: yes
limit interface: yes
Fazer um echo 4 > throttling (4 = 50%) na verdade tem o efeito de que a CPU parece estar rodando mais devagar. Eu também tentei 6 (25%) e 7 (12%). Infelizmente, o fã continua zumbindo mesmo assim.
Alguma ideia de como posso silenciar este excelente computador sem arrancar os fios (o que provavelmente não é uma boa ideia)?
