[ltp] Missing /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed

[David]

Hi,

I have a problem controlling the speed of the centrino prozessor.

I read that i've to set the speed in /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed, but this file doesn't exist...

I've only

cpuinfo_max_freq  
scaling_available_governors  
scaling_governor  
scaling_min_freq
cpuinfo_min_freq  
scaling_driver               
scaling_max_freq

all with correct values

kernel 2.6.1

any ideas?

thx

david
