set up cpufreq for pentium805d

Hello fellow arch users... Ive been trying to figure out how to set up cpufreq daemon.

i need to load a module for this model name      : Intel(R) Pentium(R) D  CPU 2.66GHz
that is what i got when i ran cat /proc/cpuinfo.

i need to type in a module name into my rc.conf file and i wasnt sure if it would be that whole line i get from the cat command or if there is a list i can locate.
and once i set that up how low can i go with the processor frequency?

Re: set up cpufreq for pentium805d

im having issues with this step:

2. Load the speedstep_centrino (from kernel 2.6.21 on don't load speedstep_centrino - load acpi_cpufreq !), cpufreq_powersave, cpufreq_userspace and freq_table modules using modprobe. Alternatively, you can add these modules to the modules list in /etc/rc.conf to load them at boot time. Addition: As of kernel 2.6.20, the speedstep_centrino module is redundant. Load acpi_cpufreq instead.

I ran modprobe acpi_cpufreq and after i ran it i got this :

FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.21-ARCH/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device

Thank You for assisting.

Re: set up cpufreq for pentium805d

To find out what package a file belongs to, use 'pacman -Qo /path/to/file'. For me, pacman lists acpi_cpufreq.ko as belonging to the kernel26 package. Which kernel are you running (get with 'uname -a')? Have you updated recently with 'pacman -Syu'?

Also, try 'cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies' to see if your cpu supports scaling.

pacman -Qo /lib/modules/2.6.21-ARCH/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko let me knopw that it belonged to the kernel, which is 2.6.21, ive just did Pacman -Syu recently.   Also i tried to cat the directory u talked about and it didnt exist. but instead of scaling_avaliable_frequencies i did see thermal_throttle.

Re: set up cpufreq for pentium805d

When you modprobe acpi_cpufreq and get that error message, try 'dmesg' and see if there are any additional error messages. Also, can you modprobe p4_clockmod?

Re: set up cpufreq for pentium805d

ok i ran dmesg and scanned it as much as i could and didnt see no errors. i then ran dmesg | grep error and actually came up with one :

ACPI: Looking for DSDT in initramfs... error, file /DSDT.aml not found.

now i just ran modprobe p4_clockmod and i got no response so that seems to be working i guess... so let me try the rest of the steps i guess.
