sensors and ITE IT8720 not working

**Hello guys.

I’ve got a problem with sensors.
I runed sensors-detect and it gave me that:**
linux-gpeu:/home/christoph # sensors-detect

sensors-detect revision 5337 (2008-09-19 17:05:28 +0200)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you’re doing.

We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no): y
Probing for PCI bus adapters…
Found unknown SMBus adapter 10de:0752 at 0000:00:01.1.
Sorry, no supported PCI bus adapters found.

If you have undetectable or unsupported I2C/SMBus adapters, you can have
them scanned by manually loading the modules before running this script.

We are now going to do the I2C/SMBus adapter probings. Some chips may
be double detected; we choose the one with the highest confidence
value in that case.
If you found that the adapter hung after probing a certain address,
you can specify that address to remain unprobed.

Some chips are also accessible through the ISA I/O ports. We have to
write to arbitrary I/O ports to probe them. This is usually safe though.
Yes, you do have ISA I/O ports even if you do not have any ISA slots!
Do you want to scan the ISA I/O ports? (YES/no): y
Probing for National Semiconductor LM78' at 0x290... No Probing for National Semiconductor LM78-J’ at 0x290… No
Probing for National Semiconductor LM79' at 0x290... No Probing for Winbond W83781D’ at 0x290… No
Probing for Winbond W83782D' at 0x290... No Probing for IPMI BMC KCS’ at 0xca0… No
Probing for `IPMI BMC SMIC’ at 0xca8… No

Some Super I/O chips may also contain sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): y
Probing for Super-I/O at 0x2e/0x2f
Trying family National Semiconductor'... No Trying family SMSC’… No
Trying family VIA/Winbond/Fintek'... No Trying family ITE’… Yes
Found ITE IT8720 Super IO Sensors' Success! (address 0x290, driver to-be-written’)
Probing for Super-I/O at 0x4e/0x4f
Trying family National Semiconductor'... No Trying family SMSC’… No
Trying family VIA/Winbond/Fintek'... No Trying family ITE’… No

Some south bridges, CPUs or memory controllers may also contain
embedded sensors. Do you want to scan for them? (YES/no): y
Silicon Integrated Systems SIS5595… No
VIA VT82C686 Integrated Sensors… No
VIA VT8231 Integrated Sensors… No
AMD K8 thermal sensors… Success!
(driver `k8temp’)
AMD K10 thermal sensors… No
Intel Core family thermal sensor… No
Intel AMB FB-DIMM thermal sensor… No
VIA C7 thermal and voltage sensors… No

**The problem is that there is no driver for the ITE IT8720 Super IO Sensors.

How can I get a driver. I tried modprobe it87 but it gives me FATAL: Error inserting it87 (/lib/modules/2.6.27.7-9-default/kernel/drivers/hwmon/it87.ko): No such device
I don’t know how to fix. Maybe somebody knows that.
My kernel is 2.6.27.7-9-default.

Hope somebody can help.**

Not sure on that kernel version but the IT87 module is in the
2.6.27.19-3.2-pae version:

/lib/modules/2.6.27.19-3.2-pae/kernel/drivers/hwmon/it87.ko

If you have the kernel source installed you can always have a read of
the kernel docs in /usr/src/linux dir and also if needed you might be
able to compile the sensors and install the needed modules.

have a look round http://www.lm-sensors.org/ and see if anything there
helps, I know this chip is supported by looking in the devices section
of the site.

The Module is there. But there is no driver for it in the module. It comes with kernel 2.6.28. That’s what I know. And there is a patch for al kernels at lm-sensors website. But it is a sourcepatch. So can I just compile the module or do I have to compile the kernel completly?

And if I need to compile only the module where can I get the source of the module and how to compile it?

Thanks
ChrBeck

Does noone know how to compile the module?

Lm-sensors homepage disagrees:

ITE IT8720F yes it87 LPC 2.6.29 (2008-10-24) Compatible with the IT8718F. Support contributed Jean-Marc Spaggiari.

Building the kernel module with newer/patched sources is enough, no need to recompile the entire kernel.

6

So I’ll have to take the 2.6.29 kernel source and just compile the one module out of the source, right?

7

Or you can just wait a few minutes and install ready made packages from my OBS repo.

Index of /repositories/home:/Akoellh

8

Where in this Repo is the package I need?

9

Depends on your architecture, kernel version and kernel type, I hope you can search for yourself.

10

Is it the full kernel means is it named kernel-2.6.29 and so on or is it just the module named like hwmon-it87 or something like that?

11

Found it named it87-kmp-default-2.6.29_2.6.27.7_9.1-2.1.x86_64.rpm.

Thanks

12

Too bad. The package doesn’t change anything. It still says driver’to be written’.

13

So your device is not supported yet.

14

It is ITE IT8720 and in 2.6.29 changelog it says that it works now. Also the LM-Sensors website says that. :frowning:

15

Did you reload the module?

16

Oh forgotten… I’ve forgotten how to do that. Was it modprobe it87 ?

17

OK works fine now. Sorry.
Is it possible to change the names of the tems and fans somewhere. Because at the moment it says fan1 fan2 and so on.
