I am trying to make cpufreq work on a Dell Inspiron 5160. I have acpi
working and acpid and cpufreqd running in 2.6.10 kernel (running Debian
Sarge). However, while reading up on frequency scaling, I see that I can
manually change the frequency with :
echo 1800000 > scaling_setspeed

and also change governor modes. But I do not have scaling_setspeed and
not many choices for governors:
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
performance

I guess since I do not have userspace among available governors I do not
have  /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed.

My kernel has CONFIG_CPU_FREQ_GOV_USERSPACE=m:
#
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
# CONFIG_CPU_FREQ_DEBUG is not set
CONFIG_CPU_FREQ_PROC_INTF=m
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=m
# CONFIG_CPU_FREQ_24_API is not set
CONFIG_CPU_FREQ_GOV_ONDEMAND=m
CONFIG_CPU_FREQ_TABLE=m


What is the corresponding module that I have to load to get
scaling_setspeed. I hope I do not have to compile this option into the
kernel to make it work.

thanks,
->HS
