Re: Frequency Scaling won't go up to full speed

Well, since the latest Kernel Update (2.6.28), CPU speed won't go up completely again... I wonder what's causing this...

Re: Frequency Scaling won't go up to full speed

Same issue here with a T9400 processor, i've been experiencing this problem since i installed arch on my laptop, using a 2.6.27 kernel, cpufreq-info, /etc/conf.d/cpufreq, and everything under /sys all show the correct scaling values, those being 800, 1.6 and 2.53, but i only get 1.6 under maximum load, it's never gone to 2.53 unless i use the performance governor but i'm using the ondemand governor.

Re: Frequency Scaling won't go up to full speed

model name : Intel(R) Pentium(R) M processor 1.73GHz
cpufreq-info: 1.73 GHz, 1.33 GHz, 1.07 GHz, 800 MHz

/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies

1733000 1333000 1067000 800000

looks okay...

/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

1730000

Thats the Problem, available is 17330000 but not 1730000! why?

old /etc/conf.d/cpufreq

governor="ondemand"

min_freq="800MHz"
max_freq="1.73GHz"

1.73GHz means 1730000!

my /etc/conf.d/cpufreq

governor="ondemand"

# valid suffixes: Hz, kHz (default), MHz, GHz, THz
#min_freq="800MHz"
#max_freq="1.733GHz"

min_freq="800MHz"
max_freq="1733MHz"

/etc/rc.d/cpufreq restart

it works have fun
