Winbond W83627GF-AW not found (Examined/Solved - lm_sensors 2.6.2 Linux 2.4.16smp/2.4.18p4smp)

[contact]

We are testing a brand new Asus A7M266-D motherboard (AMD MPX chipset), which

has a Winbond W83627GF-AW sensor chip (at least thats what is printed on it...).

This chip isn't found by sensors-detect at all. The question now is, if this

chip is supported, i.e. it isn't found because it is on some strange HW address

or because the MPX chipset itself isn't supported yet by the kernel, or if it

really isn't supported by lm_sensors itself, and therefore doesn't register with

sensors-detect.

Regards,

Holger

Relevant parts fron sensors-detect:

We can start with probing for (PCI) I2C or SMBus adapters.

You do not need any special privileges for this.

Do you want to probe now? (YES/no): Probing for PCI bus adapters...

Sorry, no PCI bus adapters found.

We will now try to load each adapter module in turn.

Do you now want to be prompted for non-detectable adapters? (yes/NO): To

continue, we need module 'i2c-dev' to be loaded.

If it is built-in into your kernel, you can safely skip this.

i2c-dev is not loaded. Do you want to load it now? (YES/no): Module loaded

succesfully.

...

Some chips are also accessible through the ISA bus. ISA probes are

typically a bit more dangerous, as we have to write to I/O ports to do

this. Do you want to scan the ISA bus? (YES/no): Probing for 'National

Semiconductor LM78'

--- Not sure if "GF" version contains sensors or not.

I know that "HF" contains sensors and "F" doesn't.

But AMD MPX chipset is AMD768.

AMD768 support was added recently to CVS / 2.6.3.

Please test and report results via email, reference your ticket number.

user followup:

Hi,

with the newest CVS version, the sensors seem to work correctly. There is

one unresolved symbol in the modules:

depmod: *** Unresolved symbols in

/lib/modules/2.4.18-pre4/misc/i2c-philips-par.o

depmod: parport_unregister_driver_Rsmp_cd2aff4a

depmod: parport_register_driver_Rsmp_a747e6da

depmod: parport_register_device_Rsmp_75a20b73

depmod: parport_unregister_device_Rsmp_0cffd5b6

depmod: parport_release_Rsmp_e2338255

depmod: parport_claim_or_block_Rsmp_aa1965f8

sensors-detect then gives:

...

Now follows a summary of the probes I have just done.

Just press ENTER to continue:

Driver 'w83781d' (should be inserted):

Detects correctly:

• Bus 'SMBus AMD7X6 adapter at e4e0' (Non-I2C SMBus adapter)

Busdriver 'i2c-amd756', I2C address 0x2d (and 0x48 0x49)

Chip 'Winbond W83782D' (confidence: 8)

• Bus 'SMBus AMD7X6 adapter at e4e0' (Non-I2C SMBus adapter)

Busdriver 'i2c-amd756', I2C address 0x49

Chip 'Philips Semiconductors PCF8591' (confidence: 1)

Driver 'lm75' (may not be inserted):

Misdetects:

• Bus 'SMBus AMD7X6 adapter at e4e0' (Non-I2C SMBus adapter)

Busdriver 'i2c-amd756', I2C address 0x49

Chip 'National Semiconductor LM75' (confidence: 3)

I will now generate the commands needed to load the I2C modules.

Sometimes, a chip is available both through the ISA bus and an I2C bus.

ISA bus access is faster, but you need to load an additional driver module

for it. If you have the choice, do you want to use the ISA bus or the

I2C/SMBus (ISA/smbus)?

WARNING! If you have some things built into your kernel, the

below list will contain too many modules. Skip the appropriate ones!

To load everything that is needed, add this to some /etc/rc* file:

#----cut here----

# I2C adapter drivers

modprobe i2c-amd756

# I2C chip drivers

modprobe w83781d

#----cut here----

To make the sensors modules behave correctly, add these lines to either

/etc/modules.conf or /etc/conf.modules:

#----cut here----

# I2C module options

alias char-major-89 i2c-dev

#----cut here----

After inserting the modules

Module Size Used by

w83781d 18160 0 (unused)

i2c-proc 6256 0 [w83781d]

i2c-dev 3616 0

i2c-core 13600 0 [w83781d i2c-proc i2c-dev i2c-amd756]

sensors gives this output:

This will require some tweaking in the sensors.conf to get the divisors

right, but otherwite looks very resonable to me.

Thanks for the quick support.
