[lm-sensors] Nuvoton W83677HG-I/W83676HG-I

[lm-sensors] Nuvoton W83677HG-I/W83676HG-I

[Lee Burchett]

I have an ASRock board that uses a newer Nuvoton W83677HG-I Super I/O 
chip. I would like to help develop (or get help developing) a set of 
drivers for this chip. It is similar to previous versions of Nuvoton 
chips like the W83627 series. I found the sensor drivers from Guenter 
Roeck (Thank You) that are intended for the W83627 series. I was hoping 
to build on these, but I don't know enough about how kernel modules work 
to proceed.

The manufacturer was helpful in providing documentation for this chip, 
the W83627UHG, and the W83627DHG-P. Comparing the devices, I noticed 
that many of the data formats and I/O methods are the same, So I hope 
that my new chip can be added in fairly easily.

I have experience writing in C, but most of programming my practice has 
been in writing programs to process data stored in files. Device I/O is 
a new field for me. Any suggestions on how to proceed, and good sources 
for information on developing a module for this chip would be 
appreciated. Thank you.

W83677HG-I and NCT6775F are the same. Did you try the existing driver ?

Thanks,
Guenter

Guenter,

I downloaded and installed the driver last night. The file I picked up 
was groeck-w83627ehf-dof3594.tar.gz. It appeared to build and install 
alright. I am using Kernel 3.0.0-16-generic on a x64 Ubuntu 11.10 
distribution.

After running make-install, I ran sensors-detect again and I still got 
this message:

Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver `adt7475':
   * Bus `NVIDIA i2c adapter 2 at 1:00.0'
     Busdriver `nvidia', I2C address 0x2e
     Chip `Analog Devices ADT7473' (confidence: 5)

Driver `to-be-written':
   * ISA bus, address 0x290
     Chip `Nuvoton W83677HG-I (NCT6771F/NCT6772F/NCT6775F) Super IO 
Sensors' (confidence: 9)

Note: there is no driver for Nuvoton W83677HG-I 
(NCT6771F/NCT6772F/NCT6775F) Super IO Sensors yet.
Check http://www.lm-sensors.org/wiki/Devices for updates.

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
adt7475
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

I am using an older version of sensors-detect. I will update that as 
well, and let you know what happens. Any other thoughts on what I should do?

Lee,

please don't top-post.

You installed the driver, but you still have an old version of
lm-sensors.

The w83627ehf driver in 3.0 already supports NCT6775F. Just add
w83627ehf to the list of modules to load.

Thanks,
Guenter
