Por alguma razão, meu processador sempre parece rodar a toda velocidade, mesmo que eu não faça nada. Olhando através da web, encontrei algumas sugestões.
De acordo com link , eu deveria poder listar meus governadores atuais.
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors: No such file or directory
Mas não posso, pois /sys/devices/system/cpu/cpu0/cpufreq não existe no meu computador.
Instalei cpufreqd cpufrequtils e libcpufreq0, mas devido ao diretório ausente, recebo
# /etc/init.d/cpufreqd start
* Starting CPU Frequency daemon cpufreqd [fail]
De acordo com o link , devo carregar um dos módulos disponíveis .
# ls /lib/modules/'uname -r'/kernel/arch/*/kernel/cpu/cpufreq
p4-clockmod.ko pcc-cpufreq.ko speedstep-lib.ko
O único que não resulta em erro é o speedstep-lib.
# modprobe speedstep-lib
Alguma ideia do que posso fazer?
# lsmod |grep cpu
# lsmod |grep freq
# lsmod |grep acpi
