I just have one quick question on how will I be able to use the Power Now and Speed Step features in Gentoo Linux. I am confuse with the instructions provided to me so please assist me on this matter.
Power Now and Speed Step Features in Gentoo Linux
In order to use the PowerNow or SpeedStep technologies in Gentoo, you first have to compile the kernel with support for these features. The process is a bit steep but can be easily learned. The process is given below
Power Management Option
Run-time PM core functionality
Cpu Frequency Scaling
Default CPU frequency governor
Userspace governor for userspace frequency scaling
Ondemand cpu frequency policy governor
ACPI processor P-States driver
CPU idle PM support
Then emerge cpufrequtils and edit /etc/conf.d/cpufrequtils with a preferred editor
# Options when starting cpufreq (given to the 'cpufreq-set' program)
# Options when stopping cpufreq (given to the 'cpufreq-set' program)
Now you only have to run rc-update add cpufrequtils boot to make sure it is started every time you boot.
