 |
|
Recently i decided to blow out the dust from my Gentoo. I've upgraded kernel to sys-kernel/gentoo-sources-2.6.23-r6 and now I don't have a directory that was essential to turn on ondemand scaling governor:
/sys/devices/system/cpu/cpu0/cpufreq/
All options under Power Management -> Frequency Scaling are [*] (except intel ones  ):
| Code: |
# cat .config | grep freq -i
# CPU Frequency scaling
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=y
# CONFIG_CPU_FREQ_DEBUG is not set
# CONFIG_CPU_FREQ_STAT is not set
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=y
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=y
# CONFIG_CPU_FREQ_GOV_CONSERVATIVE is not set
# CPUFreq processor drivers
# CONFIG_X86_ACPI_CPUFREQ is not set
# CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set
|
Any ideas how to turn ondemand on again? ~90% of thw time I'd rather like 1GHz and quiet than 2GHz...
