ITE 8702 support/query

Scroll down for additional question on this.............

I have tried to get lm_sensors to work on my HP pavillion xg838 but without any success.

Is this a known issue or a new one? I have searched everyplace for a solution but nothing has come up.

This is what it detected.......

#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----cut here----

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

#----cut here----
# I2C adapter drivers
modprobe i2c-isa
# I2C chip drivers
# no driver for ITE 8702F Super IO Sensors yet
# sleep 2 # optional
/usr/local/bin/sensors -s # recommended
#----cut here----

I am assuming the ITE 8702F chip is what I am needing.

Is there any plans on getting that coded in?

Thanks,
Scott

No, there's no plan, sorry.

If anything changes the entry on our New Drivers page will be updated.

If you plan to do the work yourself let us know.

Where could I find the info I would need?

What spec's would I need to find in order to get the sensor to work?

ITE has a product information page here, including a detailed datasheet.

 http://www.iteusa.com/product_info/PC/Brief-IT8702_2.asp

According to the datasheet, the IT8702F has no temperature nor voltage sensors, but 5 fan monitoring channels with speed control (the IT8705F and IT8702F only have 3). The first three fans registers look compatible with the other chips we already support, except that they can optionally be made 16-bit instead of using a divider.

It also has VID input support (compatible with IT8712F) which is somehow strange since it doesn't monitor voltages anyway.

It isn't very clear whether a brand new driver should be written or if support for the new chip should instead be added to the existing it87 driver.

On most systems, the limited hardware monitoring features of the IT8702F do not appear to be used. Until we find at least one system where we know for sure that the hardware monitoring features are used, there's no point in working on support.
