 |
|
Hi,
anybody knows how to enable and make Cool N Quite work on Gentoo?
I have AMD64 +3200 on an Asus A8N SLI Deluxe.
Thanks,
Spiro

enabled it in the bios and add support in the kernel.
under power saving options.

Hi and thanks for the guide.
To be sure, which part of the kernel is directly connected to Cool N Quite?
Which one of these categories?
| Code: | [*] Power Management support
[ ] Power Management Debug Support
[ ] Software Suspend (EXPERIMENTAL)
ACPI (Advanced Configuration and Power Interface) Support --->
APM (Advanced Power Management) BIOS Support --->
CPU Frequency scaling ---> |
BTW, is there any paper written on how to configure Cool N Quite on Gentoo?
Thank you,
Spiro |

CPU Frequency scaling ->
add the governors

Two more questions, if I can ask:
1) is ACPI (Advanced Configuration and Power Interface) Support ---> for reading hardware data?
2) By having an AMD64 on an nVidia nForce4 SLI MCP Asus A8N SLI Deluxe mobo. Would it be sufficinet/appropriate to enable the following (so that you could correct me if I am wrong, if possible):
| Code: | [*] CPU Frequency scaling
<*> CPU frequency translation statistics
Default CPUFreq governor (userspace) --->
<*> 'performance' governor
<*> 'powersave' governor
--- 'userspace' governor for userspace frequency scaling
<*> 'ondemand' cpufreq policy governor
<*> CPU frequency table helpers
<*> AMD Opteron/Athlon64 PowerNow! |
Once I have Gentoo and kde and gkrellm up and running how to I manage Cool N Quite?
Thank you,
Spiro |

Hi,
I bet we submitted at the same time our own post.
I thank you for your reference.
I will look into it.
How about this:
1) is ACPI (Advanced Configuration and Power Interface) Support ---> for reading hardware data?
2) is just one governor or I can have multiple governors selected?
3) Would be the case that it is better to compile into the kernel rather than compile as modules?
Thanks,
Spiro |

yup

you can select all - but only use one at a time.
3) Would be the case that it is better to compile into the kernel rather than compile as modules?
yes.

Hi ikaro,
all works fine but:
1) CPU Fan speed does not lower. It always speen at max speed
2) is it possible to decide manually what CPU speed to have?
Thank you,
Spiro
PS: I have used the following instructions: http://gentoo-wiki.com/HOWTO_PowerNow! |

yes, you change the governor to userspace and then set the frequency.
| Code: |
echo "userspace" >> /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor"
|
for 1000Mhz
| Code: |
"echo "1000000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed"
|
to change the fans speed I use this:
| Code: |
value from 48 to 244
echo "value here" > /sys/bus/i2c/devices/*-0290/pwm2
|
PS: the device number might be different in your case.

Hi ikaro,
thank you for your prompt reply.
What I ami to is to implement an automatic Cool N Quite system where the CPU automatically adapts itself, along with the fan speed, to the demand of the PC. I believe it is called the ondemand governor.
Now, is it possible that a deamon takes care of both the fan speed (proportionally speening to the heat of the CPU) and the CPU frequency?
If so, what should I do? So far, I can implement the ondemand governor but the fan speed steel is at max RPM.
Thank you for your explanations.

no idea - i know there are like 1027292727289365635238 different applications that are suppose to do that,
but, well ... none do the job right.
so good luck.,

could you please give me an advice on where to go?
This thread, as an example ( https://forums.gentoo.org/viewtopic.php?p=1970584 ) relies on cpudyn.
What is your suggestion?
Sorry but am not so much experienced and wish at least to be able to benefit of the Cool N Quite, if possible.
I thank you so much,
Spiro |

Ok ikaro, 
thank you anyway for your explanations. At least I will be able to implement what you adviced me to.
Take care,
Spiro |

usually I use ondemand governor to change the cpu frequency- however that isnt working at all
since 2.6.11, so ive just setup keybindings to change the frequency when needed.
Same thing for the fan speed.
offcourse it would be better if the kernel/some appplication could take care of this for me, but that would be too much like windows.
so i just use keybindings and it works fine.
