There are a couple different methods of doing this. Perhaps a different method will work better for you.
]]>Even without cpufreq running, my processor seems to lock itself down to 800MHz rather than the 1.6GHz it should be at. When I have turned cpufreq on, I notice no difference. It seems that my processor physical limits are seen as fine, but it doesnt seem that the scaling sees the proper selections ie: it says my processor scales form 800mhz to 1.6ghz but only says that my valid range is between 800mhz and 800mhz. Here's some possibly useful information"

I'm not quite sure as why it limits my current policy to only 800Mhz. I've tried to tell the policy what the scaling_max_freq is, but it won't let me change it.
[root@Ghost32 will]# echo -n 1600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
[will@Ghost32 cpufreq]$ cat scaling_max_freq
960000
it shows 960000 the first time I try to change it, which is odd. Then what used to happen is that minutes later it goes back to 800mhz and wont let me change it from that. More recently it has let me increase the maximum back up to 960000 but no higher.
Let me know if i'm leaving anything out or if there is any more information I can provide. I had this working on a previous install of arch, so I know acer_acpi and all this DOES work, I'm just confused as to why it will not work now.
Thanks.
Edit: I would guess that the problems I'm having are with the powernow-k8 module. Without it loaded I run at the full 1600MHz and with it loaded it stays at 1.6Ghz for a few seconds, then brings be right down to 800MHz. Has anyone else had similar problems or would they care to give any suggestions?
]]>I have modprobed everything correctly and I've checked around for every tutorial on setting this up, and nothing has worked. Oddly enough, I copied my config files etc directly from my old install of Arch ( I recently had to reformat ) but I cannot get things working.
I've set this up on numerous computers, so I don't feel like I've forgotten anything, and googling seems to turn up the possibility of a bug in the 2.6.20 kernel?
Anyone else experience anything similar?
PS. I have a 1.6ghz turion and it's stuck at 800mhz aside from a few brief seconds at startup.
]]>So... Since it ran perfect before, I wonder what caused this. I run current, I checked /etc/conf.d/cpufreq, it still contains what I set (the CPU is a Turion, which clocks from 800 Mhz to 1.8 Ghz with an intermediate 'stop' at 1.6 Ghz):
[stijn@hephaistos ~]$ cat /etc/conf.d/cpufreq
#configuration for cpufreq control
# valid governors:
# ondemand, performance, powersave,
# conservative, userspace
governor="ondemand"
# valid suffixes: Hz, kHz (default), MHz, GHz, THz
min_freq="800MHz"
max_freq="1800MHz"
As you can see my max & min frequencies are set. Now this is what I get when i query cpufreq:

current policy: frequency should be within 800 MHz and 1.44 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.
Before (I rebooted to make sure this problem persisted) the frequency range showed 800 Mhz and 800 Mhz (instead of the 1.44 Ghz it's showing now - I don't even get where the hell it gets that last frequency from). Nevertheless, those values are utterly incorrect - and despite of the governor being the 'ondemand' one, my CPU doesn't clock higher under significant load.
Did someone experience similar problems? I am running the 2.6.20.7 ck kernel.
Any help is appreciated
