[lm-sensors] Nuvoton W83677HG-I

[lm-sensors] Nuvoton W83677HG-I

[Tapani Tarvainen]

I got an Intel DQ57TM motherboard, sensors-detect says it has

    Chip `Nuvoton W83677HG-I Super IO Sensors' (confidence: 9)

for which there's no driver yet.

http://www.lm-sensors.org/wiki/Devices says there's been
only one request for it; for what it's worth, here's another.

I don't want it quite badly enough to donate a board for
the development (I might pitch in a small donation though),
but I'd be more than willing to help in testing &c.

I might even have a go at it myself, but I'd need a bit of
help to get started, most importantly: where does one get
specs for these things? Is it possible to get docs from
manufacturers (Nuvoton website doesn't look promising)
or is it just experimenting/guesswork based on other
maybe-similar older chips or does one have to reverse
engineer Windows drivers or what?

another request from me (intel dh57jg). ready for testing and for a small
donation as well

For Nuvoton, you send a request to ComputerIC@nuvoton.com and ask nicely.
The datasheet to ask for is probably NCT6776F (it used to be
NCT6775F, but it looks like they added another variant).

Thank you! Let's see if I managed to ask nicely enough. :-)

[no tellin]

I'm sorry, I just realized I left out an essential part of what I
wanted to post.

I chose to link to a specific example post of mine not only as a
general example, but as a specific example regarding Winbond and fans.

It's my personal experience and observation that with Winbond, lm
sensors will usually display some reasonable values. In those cases
where all the fan values are 0, it usually seems to be a matter of
using the correct divisor.

I especially chose the Asus K8N-DL as the eample because of this very
issue. The generic values {without a motherboard specific
configuration file} displays a default divisor of 2 for all fans and a
value of 0 for same. The K8N-DL not only has a different default
divisor for all fans {4 instead of 2}, but also has a single fan with
an exception {divisor of 1} and also requires further calculation.

I'd suggest you create a motherboard specific configuration file (like
in the example I gave) and try different divisor values.
