[lm-sensors] IT8702F request

[Gerold Gruber]

Hi,

the list http://www.lm-sensors.org/wiki/Devices says,
there is a data sheet for the IT8702F sensor, and three requests.

Well, you can add me to the list of requesters ;-)

I could take part in testing.

Thanks,

Gerold.

Done.

Note that I wouldn't be surprised if most IT8702F chips were not wired
for monitoring. These chips are rare and only include fan speed
sensors, no voltage sensors nor thermal sensors as other ITE Super-I/O
chips do. Does the BIOS report any fan speed?

You may provide a dump of the hardware monitoring I/O area of your chip
and I'll tell you whether it appears to be actually monitoring fans.
This will prevent you from waiting for a driver that you don't actually
need. It's relatively easy. Take the address sensors-detect reported
the chip was at. Typically it's 0x290. Then call isadump on this
address with offsets 5 and 6, typically:

isadump 0x295 0x296

From the output I can tell you whether fans are monitored or not.

BTW, if someone wants to write this missing driver, that should be an
easy one. I would do it myself if I had the time (or if someone pays me
to do the work.)

No, it doesn't.
Nothing, simply nothing.
It took me so long to verify this 'cause the system is located normally 500 km
from my office. But now I am at this place and found myself in error having
thought I had seen sensor data before :-(

So we can drop all the rest of my request.

Thanks for your effort.

Best regards

Gerold.

Done, thanks for letting us know.
