[gentoo-user] FAN-Speed readout/control ???

[gentoo-user] FAN-Speed readout/control ???

[meino.cramer]

Hallo,

I want to read the fan speed and want to control it with gentoo.

My motherboard is a ASUS Crosshair IV Formula.

lm_sensors does not report any relevant sensor.

Does anyone got this working on this or an equivalent board with 890FX
chipset?

Thank you very much in advance for any help!
Best regards

I'll tell you how I did mine.  Just build all the sensor drivers into 
the kernel, not modules but built in.  Compile and boot the kernel.  
Methos one, if you open gkrellm and it can see the fans, temp and such, 
then it is working.  Sometimes you can look in gkrellm's configuration 
and find the driver.  When you open the sensors window, it will list the 
path which contains the name of the sensor.  Another way, cat 
/sys/devices/platform/ then hit tab twice.  Mine for example lists 
it87.552.  The it87 part is what you look for in the kernel.  If you 
want to be certain it sees everything, continue with the cat command and 
hitting tab until you get to where it lists all the fan and temp files.  
Mine has two temps and about 4 fans I think it is.  If you see what 
should be there then you have the right one.

Then go back to the kernel and remove everything but the one that 
matches what you found either in gkrellm or the cat command.  Rebuild 
the kernel and reboot.

This seems like a lot of trouble but after spending about two hours on 
google and not finding the info, that was what I did.  It isn't always 
the easy way but it works for me.

You could also google for "linux compatible hardware" and see if someone 
was nice enough to post what they used on one of those sites.  That 
doesn't always work.

Hope that helps or gives you a good chuckle for the round about way of 
doing it.  lol

A simpler way:

- make sure you have CONFIG_I2C_CHARDEV=y, CONFIG_I2C_HELPER_AUTO=y and
select the correct I2C hardware bus drivers for your platform
(CONFIG_I2C_I801 for most recent Intel chipsets and CONFIG_I2C_PIIX4 for
most recent AMD chipsets; reading the help text of the various drivers
should point you in the right direction);

- emerge sys-apps/lm_sensors

- run sensors-detect

- enable the drivers for all the things sensors-detect finds. Hopefully
you won't have any unsupported chips...

- you can then add lm_sensors to the default runlevel, so that it loads
the correct modules during the boot process.

The final step is to configure the software you use to display the
sensor readings. It is usually a matter of attaching the correct labels
to the various inputs, and possibly tweaking the scaling factors so that
the readings match those shown by the BIOS; as the details depend on the
specific manufacturer and model of your board, this will usually be a
trial and error process, although google might help you. The comments in
/etc/sensor3.conf, which controls software using the libraries provided
by lm_sensors, are also a useful source of information.

> cat /sys/devices/platform/

This will miss those sensors which do not appear as a platform device
(e.g. the AMD k10 on-die temperature sensors, which is a PCI device).

Hi Andrea, Hi Dale,

Before I post my question I did, what you have suggested, Andrea.
Sensors-detect reports the it87 chip to be included as module/in the
kernel, which I did -- but the driver does not produces any output

AMD k10 was already in and reports everything -- only the fan stuff
was missing, which (normall) the ITE (it87) chip is used for.

The version of lm_sensors, which is in portage reports here "driver to
be written" but the svn-version of lm_sensors seems to support it. I
installed that svn-version locally but I cant read from the ITE
chip.
Still only voltages and temperatures.
GKrellm (normally I use conky) also detects no fans.

@Dale:
Do you have exactly the same board (ASUS Crosshair IV formula) as I, or?

I tried to include "everything" into the kernel but unfortunately the
results are the same: No fans and the it87 driver seems not to work
for me...

Any other ideas?

Best regards and have a nive sunday!

I have a Gigabyte mobo here.  There are two places that you have to 
enable all the sensors tho.  As was posted a bit ago, one is I2C Support 
and one is Hardware Monitoring Support both of which are under Device 
Drivers.  Is it possible that you left one out?

If you built all the drivers in and it didn't work, then you may have to 
wait on a newer kernel.  If you are running a stable kernel, you may 
want to try a unstable one since they are newer and may have the updated 
drivers.  I'm using 2.6.36 gentoo-sources here.

Hope that helps.

Hi Dale,

I enabled CONFIG_HWMON=y and CONFIG_I2C=y, I also see temperatures
and voltages (I still a little confused by what ASUS states of 
the CPU-dye temperature of not being a physical temperature but one
of "arbitrary scale"...but this another field to explore...).

My kernel is a 2.36.6.2 vanilla...I didn't found any newer ;) ;) ;)

Seems I am lost ?!?

build all sensor drivers AND all transport as modules
run sensors-detect
edit lm_sensors conf in /etc/conf
rc-update add lm_sensors default
pwmconfig
lots of stuff
rc-update add fancontrol default.

There are some problems with asus boards. They need some acpi support - and if 
they can do the fancontrol you have to deactivate that in the bios (google!).

I used fancontrol with all my asrock boards.
With my Asus board I am using the bios control, because it works pretty well. 
And always. And for all three fans connected. Even the ones connected with 
3pin connectors.

I built me a new rig in the past week.  There are two reasons I don't 
buy bleeding edge.  1:  Cost  2:  Drivers not being ready and/or 
stable.  My mobo is about a year old.  That is enough time to let the 
kernel people sort out some nice drivers.

Maybe someone here can point you to a place where you can see if they 
are being worked on.  I'm sure there is a website with all kinds of 
info.  The only one I can think of is http://kernel.org/ which shows a 
newer version than I have.  May could see if they have new ones in them.

Given what lm-sensors says and the fact the ones in the kernel don't 
work, I'm not sure what else to try.

Current IT87xx chips provide fan, temperature and voltage readings.

If you built the drivers as modules, are you sure everything (it87 and
the relevant i2c drivers) is loaded?
Check the kernel log for any error messages.

Support for a specific sensor chip is provided by the kernel driver, not
by lm_sensors. sensor-detect only provides advice based on the situation
at the time it was released; if a more recent revision says that the
chip is supported, it means that a driver for the chip now exists, *not*
that the driver provided by the current kernel supports it.

However, according to this page the it8720F chip seems to be supported
starting from kernel 2.6.29, so kernel version is not your problem.

The chip on the board is a ITE IT8721.

An excerpt of the top part of
/usr/src/linux-2.36.6.2/drivers/hwmon/it87.c 


 *
 *  Supports: IT8705F  Super I/O chip w/LPC interface
 *            IT8712F  Super I/O chip w/LPC interface
 *            IT8716F  Super I/O chip w/LPC interface
 *            IT8718F  Super I/O chip w/LPC interface
 *            IT8720F  Super I/O chip w/LPC interface
 *            IT8726F  Super I/O chip w/LPC interface
 *            Sis950   A clone of the IT8705F
 *

 Therefore the chip is unsupported and the kernel is the source of the
 problem according to your explanations.

So look at the lm sensors site:

 ITE    IT8721F, IT8758E    yes    it87    LPC    2.6.37 or  standalone driver    
(2010-10-12) We have a datasheet for the IT8721F. Different from previous 
IT87xxF chips (12 mV ADC instead of 16 mV, amongst other.) Two requests ( Jae 
Sammy,  Virgil Gheorghiu.) The IT8758E was reported to have the same device 
ID, so hopefully they are fully compatible. Support added by Jean Delvare, 
please test the standalone driver and report.

you could try this:

google. 2minutes. It really is that simple.

Instead I backported the i87.c driver from the upcoming linux
2.36.7.rc5 itree into my linux-2.6.36.6 kernel.

After recompiling i and a reboot it loads well but dmesg shows that
there were conflicting ACPI areas then. The driver itsself suggests to
use the atk0110-acpi driver instead the it87 one.

So I will do that and give the BIOS the full control over the fans.

I did the same and it is working really well... apart from an annoying cpu-fan

Hi Volker,

THAT'S INTERESTING!!

What motherboard do you use and may be you can mail me your kernel
config in a personal mail ?
And: What exactly do you enable/disable in the BIOS of you board?

When I try to enable fan control via bios I got a warning and loud
beeps from the BIOS *AND* the fan do not start...

When disabling fan control, the fan starts nearly instantly 
(acoustic-wise it is not that a problem ... the CPU fan works 
silently...).

But what is the reason for the ACPI area conflict???

M4A79XTD EVO
config will come per pm.

on: acc, c1e, usb, fan control (setting to optimal), ahci modus, on on 
keyboard/space bar, some other stuff. 
Off onboard sound, firewire, serial and all the other stuff I never use... oh and 
PNP OS, if I remember correctly.

yeah and if you ignore that it should start rotating after a short while. The 
starting volts at room temperature are too low, but as soon as the cpu heats 
up, the volts increase and the fan spins.

that it87blabla can be accessed by acpi stuff but the it87 driver does not know 
about it - or something like that. Read about it a few month ago and forgot 
everything.

On Asus boards try first the Asus ACPI driver, asus_atk0110

It seems more sensors are being made available through ACPI interfaces,
but many drivers still use direct access to the chip.

I have, on occations, found this database does
not get updated as it should:

run this manually, and see if it helps:

/usr/sbin/update-pciids         <updates list of pci device numbers>

I did not see your explicit board or chipset at the 
coreboot.org site.

IF you are adventuresome.....
Well, there are some similar chipsets  to yours and bios source code, 
you could test out? Talk to the devs at "coreboot.org" before
you test out any hack on your board:


http://www.coreboot.org/Supported_Motherboards

The devs and the project has been around for a long time,
previously known as linuxbios.....

caveat emptor!

great way to wreck a perfectly working board.
