[gentoo-user] Thermal cpu

[gentoo-user] Thermal cpu

[Sylvain Chouleur]

Hello

I have a little problem on my gentoo, when I check the temperature I see 
that it is always about 10°C higher than when I am on debian. However, the 
cpu is at 0.3% used, as in debian.

The problem is that with this gap, the fan is always active and I want that 
my gentoo be well installed

Have any ideas to resolve that problem?

Thank you very much

Sylvain Chouleur

Check the file /etc/sensors.conf (or copy the debian file)

But I don't have this file
What program is supposed to make it?

How are you checking the temperatures?

I use the lm-sensors built into the kernel and I don't have that file
either.  If he is using the kernel drivers that may be why he doesn't
have it.

Than again, I may be wrong too.  Funny thing is, mine is accurate as
compared to what the BIOS says.  Funny it is off like that.

I think some chipset don't give the temperature directly, actually return a numerical value and you have to 
run a math formula to calculate the correct temperatura.

With the app lmsensors

*  sys-apps/lm_sensors
      Latest version available: 2.10.1
      Latest version installed: 2.10.1
      Size of downloaded files: 2,663 kB
      Homepage:    http://www.lm-sensors.org/
      Description: Hardware Monitoring user-space utilities
      License:     GPL-2

in the file /etc/lmsensors.conf you must config the formula

With acpi I don't know how configurate, but I think you can use lmsensors to read acpi information.

If you don't find how to configure acpi, try lmsensors

no. You 'must' not.

For most chips and a lot of mainboards the correct formulas are already there. 
So there is no need to do anything. Just emerge lmsensors and be happay.

You will probably need to run sensors-detect after emerging it.

IIRC you have to start lm_sensors first.

Looks like one of the needed modules isn't being loaded correctly or somesuch. 

Sensors-detect should have given you a list of the modules needed - try loading them all manually and run `sensors` ? (minus quotes)

PS The comments regarding top posting are for your attention, by the way. It takes two seconds extra to bottom post vs top post and makes it much easier to follow a thread :)

Re: [gentoo-user] Thermal cpu

[Sylvain Chouleur]

I tried to install and use lm_sensors but it don't detect any sensors.
Moreover, I think it's a problem of acpi or the kernel configuration because 
on my debian, I don't use lm_sensors, just acpi.

May be detection is bad made or may be cpu id bad used, but top show me 
that:
top - 23:01:52 up 23 min,  6 users,  load average: 0.28, 0.25, 0.25
Tasks:  86 total,   3 running,  82 sleeping,   0 stopped,   1 zombie
Cpu(s): 10.3%us,  1.7%sy,  0.0%ni, 69.4%id, 16.9%wa,  1.7%hi,  0.0%si,  
0.0%st
Mem:    448112k total,   305916k used,   142196k free,    29056k buffers
Swap:   747012k total,        0k used,   747012k free,   161780k cached

and acpi -t:
Thermal 1: ok, 65.0 degrees C

And at this state, on debian, the thermal is at 53 degrees C so and don't 
understand.

Is there some option to activate in the kernel to support better the thermal 
or cpu use?

(I'm using a mobile AMD Athlon(tm) XP2400+, 1788.817Mhz)

Thank you for your help!

Since there are really lots of drivers, I just guess you didn't compile
the right ones when building your kernel.

That's two completely different things.

OK, so ACPI temperature zone support is working.

If that's why you posted top output: It doesn't depend on absolute
load. Maybe your debian box enables throttling, either ACPI P-States,
or CPUfreq. You might want to play with the cpufreq ondemand governor
(there's also an alternative implementation, read the docs of those
kernel options) or cpufreqd.

CPUfreq, see above. And it certainly won't make CPU use better (it
throttles) -- but might lower the temperature.

Re: [gentoo-user] Thermal cpu

[Sylvain Chouleur]

Hello!

I have found the source of my problem:
I've not a wifi card integrated in my laptop and so I'm using a usb dongle 
with ndiswrapper driver.
And it's when this usb key is plugged that the acpi temperature is growing 
and it don't happens if it's a classic usb key (storage for example) which 
is plugged.

So we have changed the problem!
But it is not resolved :(

So do you have any idea for this problem??

Thank you for your help!

Well, that's somewhat better, but still not ideal.

top post: v.
 1. Writing your entire reply to a message (generally email or newsgroup 
posting) above any quoted material you are replying to.

bottom post: v.
 1. Writing your entire reply to a message (generally email or newsgroup 
posting) below any quoted material you are replying to.

Top posting is generally considered either wasteful, if the quoted part 
isn't 
required, or confusing, since the answers to questions will appear the 
questions themselves and the "conversation" will generally be read in the 
wrong order.  This being said, top posting is preferred in some fora.  Top 
posting is a common beginner (see n00b) behavior in the face of properly 
behaving email/newsgroup client (see below).  At least one mail client 
(Microsoft Outlook) makes it intentionally difficult to not to top post, 
though cursor, signature, and quoted material placement AND non-standard 
quoting methods.

Bottom posting is preferred over top posting in most fora, but is still 
wasteful especially in combination with "me too" posts, in which the volume 
of quoted (and thus at least partially redundant) material greatly dwarfs 
the 
amount of unquoted (and ideally original) material.

The most preferred method of replying is sometimes called "interleaved 
posting".  In this case you quote only the relevant parts of the message 
you 
are replying to, leaving only enough information to provide a context for 
your material.  The appropriate amount of quoted material can differ 
greatly 
based on the fora for which the message is intended.  Your material is 
placed 
after what it is replying to, which might be before other quoted material.  
Here's an example:

--- Begin Example ---
>> I've filed bug XXX against foo/bar-1.1_pre2; it breaks some of my 
scripts
>> I wrote against foo/bar-1.0 
>
> That's not a bug.  It's a feature.
> Riposte A

I see the security implications, but I've attached a patch that retains the 
1.0 behavior while addressing the buffer overflow risk in a future-proof 
manner.

> Riposte C

This is the problem with open source software.  The %#$@ developers want it 
to 
be broken.  That's a stupid point and you should be ashamed for presenting 
it.
---  End Example  ---

In the example above, the "Riposte B" text was dropped since the message 
contained no direct reply to it.

A properly behaving email/newsgroup client, in absence of other user 
preferences, should quote the entire message being replied to (the 
format=flowed RFC covers acceptable quoting methods), place the user's 
cursor 
at the top (or slightly above) the quoted material, and automatically 
insert 
the content of the users signature (on UNIX, baring other configuration, 
this 
is in contents of the file $HOME/.sig) below the quoted material after the 
standard signature separator ('-- ' on it's own line).  The user will then, 
move down the message, deleting quoted material irrelevant to their reply 
and 
writing their content immediately after the relevent quoted material and 
stopping when they reach the signature separator.  New users often simply 
type their reply, without touching the quoted material resulting in a top 
post (see above).
