Hello,

# uname -a
Linux box 2.6.31.3 #2 SMP Wed Oct 14 04:55:36 EDT 2009 x86_64 GNU/Linux

I have a DP55KG motherboard, it says Ibex support was added here:
http://www.lm-sensors.org/changeset/5375

# sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

I have all of the modules compiled into the kernel and sensors-detect does
not find anything.

00:1f.3 SMBus: Intel Corporation Ibex Peak SMBus Controller (rev 05)

Any ideas?

Justin.

I tried w83627ehf, to no avail:

# modprobe w83627ehf
FATAL: Error inserting w83627ehf (/lib/modules/2.6.31.3/kernel/drivers/hwmon/w83627ehf.ko): No such device

With debugging enabled:

[56208.376451] w83627ehf: unsupported chip ID: 0xb473

Is there anything else needed from me/info about the board or once this ID
is added into the kernel/src/etc it will work properly?

The "Ibex support" in question only refers to the SMBus controller, not
to sensors directly.

We have never heard of this chip ID. This must be a brand new
Winbond/Nuvoton Super-I/O chip. Please look at the motherboard, search
for the Super-I/O and report the top marking. You may also find its
name in the user manual (but the top marking is even more reliable.)

No, for now it's enough. This would indeed be a new chip, not even
listed on Novoton's site yet. I'll ask our contact at Nuvoton about it.

Please give a try to the latest version of sensors-detect:

http://dl.lm-sensors.org/lm-sensors/files/sensors-detect

It should find your chip now. Next step is to actually add support for
it, but it will take more time and efforts.

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.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD Family 11h thermal sensors... No
Intel Core family thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal and voltage sensors... No

Some Super I/O chips contain embedded 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):
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... Yes
Found `Nuvoton W83677HG-I Super IO Sensors'
(but no address specified)
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no):
Probing for `IPMI BMC KCS' at 0xca0... No
Probing for `IPMI BMC SMIC' at 0xca8... No

Some hardware monitoring chips are 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):
Probing for `National Semiconductor LM78' 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

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Found unknown SMBus adapter 8086:3b30 at 0000:00:1f.3.
Sorry, no supported PCI bus adapters found.

Next adapter: SMBus I801 adapter at 7000 (i2c-0)

Sorry, no sensors were detected.
Either your system has no sensors, or they are not supported, or
they are connected to an I2C or SMBus adapter that is not
supported. If you find out what chips are on your board, check
http://www.lm-sensors.org/wiki/Devices for driver status.

So the LPC interface to the hardware monitoring chip is disabled.

You have an unknown chip at 0x2c on the SMBus. It could be a hardware
monitoring chip... or not.

If you want me to investigate this, you can provide an I2C dump of the
chip. Get i2cdump from the i2c-tools package, and then:

# i2cdump 0 0x2c b

This might confuse the chip in question though, so only try it if you
are ready to trigger a cold reboot.

This is the SMBus access to the W83677HG. We don't have support for
that, because LPC access is faster and was always enabled on all
motherboards we've seen so far.

I doubt we'll ever add SMBus access support, for both performance and
source code readability reasons. If anything, we could forcibly enable
the device on your motherboard. But please first look for BIOS options
and/or a BIOS update to enable the LPC interface.

Do you see any hardware monitoring information in the BIOS?

Ok, luckily it does not appear to have caused any issues:

I am checking now...yes all HW monitoring/etc IS enabled.

Yep, see note above. It is enabled.

Smells like an Analog Devices chip, but not one we know... And I can't
see it on the web site you mentioned. Please search for a small-size
chip named ADTxxxx (more likely ADT74xx).

Ah, ADT7490. Please try:

http://dl.lm-sensors.org/lm-sensors/files/sensors-detect

We don't have support for that chip, but the datasheet suggests some
form of compatibility with the ADT7473 and ADT7475, which we do have
support for. So support for the ADT7490 is probably not too far away.

The presence of this monitoring ASIC explains why the hardware
monitoring features of the W83677HG super-I/O are disabled.

Hi,

Cool.

# md5sum sensors-detect*

# Board: Intel Corporation DP55KG

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.

Some south bridges, CPUs or memory controllers contain embedded sensors.

Do you want to scan for them? This is totally safe. (YES/no): YES


Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD Family 11h thermal sensors... No
Intel Core family thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal and voltage sensors... No

Some Super I/O chips contain embedded 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): YES


Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No

Trying family `VIA/Winbond/Nuvoton/Fintek'... Yes
Found `Nuvoton W83677HG-I Super IO Sensors'
(but no address specified)

Probing for Super-I/O at 0x4e/0x4f

Trying family `National Semiconductor'... No
Trying family `SMSC'... No

Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such

interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): YES


Probing for `IPMI BMC KCS' at 0xca0... No
Probing for `IPMI BMC SMIC' at 0xca8... No

Some hardware monitoring chips are 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): YES


Probing for `National Semiconductor LM78' 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

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.

Do you want to probe the I2C/SMBus adapters now? (YES/no): YES


Found unknown SMBus adapter 8086:3b30 at 0000:00:1f.3.
Sorry, no supported PCI bus adapters found.

Next adapter: SMBus I801 adapter at 6000 (i2c-0)
Do you want to scan it? (YES/no/selectively): YES
