We use 64 bit OpenSuSE kernel 2.6.27 (patched for right numactl work)
w/OpenSuSE sensors 3.0.3 (w/libsensors4) packages installed.
Motherboard Supermicro X8DTI has w83795adg (I beleive) chip, and I
obtained from Supermicro Tech Support the necessary data (see below)
for /etc/sensors3.conf
1) 1st of all, I need to install "stand-alone" w83795 driver for my
kernel.
Do I understand correctly that simple issuing of "make all" under root
is enough ?
(of course, I do not say about w83795 loading).
2) Am I right in a pair of "compute" statements for in3 and in4
values:
compute in3 @*0.032, @/0.032
compute in4 @*0.008*6.62, @/0.008/6.62
if I base on data supplied by Supermicro (below, they are for 5V and
12V) ?

Hi,
just download the driver, the make file and i2c-compat.h from
http://khali.linux-fr.org/devel/misc/w83795/ the do a make && make install
That should be enough to install the driver for your kernel. A modprobe
w83795 should then load the driver and sensors should show values :)
Regards
Ian Dobson

Hi Mikhail,
Sorry for the late answer. I am the (co-)author of the w83795 Linux
driver.

Not sure what you mean with "under root". If you meant "as root user",
then please no, _never_ build software as root user. Build as a regular
user and only install as root. Other than this, yes, "make" as a
regular user and "make install" as root should be enough, although you
may have to do it again whenever you upgrade your kernel.

No. The 0.008 above corresponds to the ADC resolution, and the driver
handles it. The only part of the conversion which goes in the
configuration file is the external scaling factor.
So you want:
compute in3 @ * 4, @ / 4
compute in4 @ * 6.62, @ / 6.62

Apparently the SuperMicro engineers had fun with the fan numbering ;)
This can be translated to the following configuration statements:
label fan1 "Fan 1"
label fan2 "Fan 7"
label fan3 "Fan 2"
label fan4 "Fan 4"
label fan5 "Fan 6"
label fan6 "Fan 8"
label fan7 "Fan 5"
label fan8 "Fan 3"

No scaling needed except for +5V and +12V, already discussed above.

These are already handled by the driver.

These correspond to temp7, temp8 and temp5, respectively. So:
label temp5 "Sys Temp"
label temp7 "CPU1 Temp"
label temp8 "CPU2 Temp"

Supported by the driver, no configuration needed.

We don't have support for this feature.
I have come up with the following configuration file, please give it a
try:
