cpufreq default governor?

cpufreq default governor?

[Diwaker Gupta]

Hi,

I'm running 2.6.1 vanilla kernel from kernel.org with no patches. I want 
to set the default cpufreq governor to userspace. Here is the relevant 
portion of my .config:

====
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_PROC_INTF=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=y
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_24_API=y
CONFIG_CPU_FREQ_TABLE=y
CONFIG_X86_ACPI_CPUFREQ=y
CONFIG_X86_ACPI_CPUFREQ_PROC_INTF=y
====

Everything compiles fine, but when I boot into the new kernel, the 
default governor is still set to performance:

<diwaker@diwaker>$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
performance

But the userspace governor is indeed available:
<diwaker@diwaker>$ cat 
/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
powersave userspace performance

Any suggestions?
TIA,
Diwaker

Hi,

I'm sorry but I cannot reproduce the behaviour you see. Do you run any
userspace cpufreq tool like cpufreqd? Can you compile the other governors as
modules, and see what happens then, please? Thanks,
	Dominik

Hi,

Sorry, really stupid of me. It seems cpudynd or acpid are changing the 
default governor! I booted with both services off and the governor 
showed up okay.

BTW, do people have any opinion on which frequency daemon is better -- 
cpudynd or cpufreqd?
