If sensors-detect didn't see the W83795ADG chip, this is the problem.

The w83795 driver uses the same detection mechanism used in
sensors-detect. So if sensors-detect doesn't see your chip, I am not
surprised that the driver didn't either.

The full output of sensors-detect is needed to diagnose your problem
further. It could be that your SMBus controller isn't supported, or
maybe you are supposed to access the chip through IPMI.
It is also possible that your documentation is incorrect and your
system doesn't actually have a W83795ADG chip.

IPMI is probably the key..
From the sensors-detect output:
"Warning: the required module ipmisensors is not currently installed
on your system. If it is built into the kernel then it's OK.
Otherwise, check http://www.lm-sensors.org/wiki/Devices for
driver availability" (full ouput attached)
I did see the output before, but didn't really understand the
implications (IPMI seems to be an alternative way of accessing the
monitoring chips?)
The suggested ipmisensors driver however does not seem to be available, right?

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD Family 10h thermal sensors... Success!
(driver `k10temp')
AMD Family 11h thermal sensors... No
Intel Core family thermal sensor... No
Intel Atom thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal sensor... No
VIA Nano thermal sensor... No
Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): Found `IPMI BMC KCS'... Success!
(confidence 8, driver `ipmisensors')
Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): Using driver `i2c-piix4' for device 0000:00:14.0: ATI Technologies Inc SB600/SB700/SB800 SMBus

Yes. The strength of IPMI access is that it can be used remotely too,
for example from a BMC plugged into your system.

That project is essentially dead. At the time being, the best way to
retrieve IPMI-based sensor values is using "ipmitool sensor". The
drawback is that this isn't integrated with libsensors, so the usually
monitoring applications won't work.
If you have a BMC or are otherwise already using IPMI on your machine,
just use ipmitool and you're done.
If not, then it might be worth trying ipmitool once, and then try
sensors-detect again. There is a small chance that, once ipmitool
managed to access the monitoring device, sensors-detect will see it. My
own mainboard which has a W83795ADG chip has a multiplexed SMBus, and I
can only see the W83795ADG in sensors-detect when the multiplexer is
set properly. Otherwise I would see the memory modules, which _do_
appear in your sensors-detect output. So maybe your board has a
multiplexed SMBus too.
If the trick doesn't work, you may want to try the new jc42 driver
which can monitor the temperature of some DDR3 memory modules. I
suspect your memory modules have such sensors. A more recent version of
sensors-detect would confirm that:
http://dl.lm-sensors.org/lm-sensors/files/sensors-detect
I also see that sensors-detect suggested to use the k10temp driver,
which your kernel doesn't have. You can try the standalone flavor of
the drivers which I maintain at:
http://khali.linux-fr.org/devel/misc/k10temp/
The accuracy of the CPU internal sensors is limited, but that's still
better than nothing.

Now there is:

Should work fine as long as your kernel is recent enough (2.6.26 or
later.)

The base address of 0 is suspicious. I used to have this on my Asus
board but a BIOS update fixed it. You may want to look for a BIOS
update for your system or a BIOS option to enable the IPMI controller.
Note that I did not manage to get IPMI to work on my system either so
far, I really don't know much about it so I am probably not the best
advice provider in this area.
If you have technical documentation for your system, it would be
interesting to see if they mention anything about IPMI or about the
SMBus being multiplexed.

'sensors' now gives:

So I wanted to change both names and thresholds for the two jc42
readings. I succeeded with the names (after understanding the 'bus'
statement..), but I did not manage to set temperature thresholds.
The current config file:

/
chip "jc42-i2c-0-18"
label temp1 "DRAM_0"
set temp1_min 0

chip "jc42-i2c-0-19"
label temp1 "DRAM_1"
set temp1_min 0
set temp1_max 65
set temp1_crit 70/
still gives:

The 0 limits are a little odd. I would expect these sensor chips to get
up with sane defaults... But apparently they don't. I can't find any
mention of default values for these registers in the datasheet.
The good news is that your memory modules are pretty cool :)

Assuming the trailing "/" is a typo, the above looks OK. Note that the
temp1_min are not needed, as the value is already 0. As I2C writes
aren't cheap, you may want to omit them for a slightly faster boot.

Honestly, you are a very pleasant user to deal with. You're looking for

indeed - I remember having read that before, but just forgot ..
now setting the limits does work for jc42 _min and _max values, however
not for _max_hyst (although the setting seems to exist)
The latest config file:
/bus "i2c-0" "SMBus PIIX4 adapter at 0b00"
chip "jc42-i2c-0-18"
label temp1 "DRAM_0"
set temp1_max 60
set temp1_crit 70
set temp1_max_hyst 65
chip "jc42-i2c-0-19"
label temp1 "DRAM_1"
set temp1_max 60
set temp1_crit 70
set temp1_max_hyst 65
/
and the latest output
/karsten:~/temp$ sudo sensors -s
Error: File /etc/sensors.d/jc42.conf, line 7: Failed to set value
jc42-i2c-0-18: At least one "set" statement failed
Error: File /etc/sensors.d/jc42.conf, line 14: Failed to set value
jc42-i2c-0-19: At least one "set" statement failed/
(actually I get the same error message for the K10temp _min & _max
settings, but maybe these are hardwired?)

There's a trick: temp1_max_hyst exists but is read-only.
temp1_crit_hyst is writable, set it and the same delta will be applied
to temp1_max_hyst (relative to temp1_max, obviously.) The reason is
that there's only one register in the chip to store the delta, and it
applied to both limits.

Yes they are hardwired for k10temp.

The ones I have tested all have their default limits set to 0 degrees
and, as result, report alarms until the defaults are changed.
Odd but true.

Hi Jean...
The bios show fan rpm and temperature. Since my own proliant
microserver lacks of ipmi card, I doubt the bios give me the results
using ipmi call.
The HP Proliant Microserver chipset (SB820M) have a multiplexed smbus like your.
http://support.amd.com/it/Embedded_TechDocs/47283_sb820m_ds_pub_2.00.pdf
Here is technical document from amd...
at p52/53 they say:
(1) The SDA1 and SCL1 SMBus interface is dedicated for ASF devices
only. It should not be used to
connect to any other devices.
(2) There are only two SMBus controllers. The SCL1/SDA1 pair is
controlled by SMBus controller 1.
SCL0/SDA0, SCL2/SDA2, SCL3/SDA3 and SCL4/SDA4 are multiplexed pins
that are all controlled by
SMBus controller 0, and only 1 pair of those pins can be active at any time.
I can't understand how to enable 2, 3 and 4 muxed bus..
If you consolidate a solution for i2c-i801.c I hope we can be
replicated for i2c-piix4.c too..

Yes. The strength of IPMI access is that it can be used remotely too,
for example from a BMC plugged into your system.

*
That project is essentially dead. At the time being, the best way to
retrieve IPMI-based sensor values is using "ipmitool sensor". The
drawback is that this isn't integrated with libsensors, so the usually
monitoring applications won't work.
If you have a BMC or are otherwise already using IPMI on your machine,
just use ipmitool and you're done.
If not, then it might be worth trying ipmitool once, and then try
sensors-detect again. There is a small chance that, once ipmitool
managed to access the monitoring device, sensors-detect will see it. My
own mainboard which has a W83795ADG chip has a multiplexed SMBus, and I
can only see the W83795ADG in sensors-detect when the multiplexer is
set properly. Otherwise I would see the memory modules, which _do_
appear in your sensors-detect output. So maybe your board has a
multiplexed SMBus too.
If the trick doesn't work, you may want to try the new jc42 driver
which can monitor the temperature of some DDR3 memory modules. I
suspect your memory modules have such sensors. A more recent version of
sensors-detect would confirm that:
http://dl.lm-sensors.org/lm-sensors/files/sensors-detect
I also see that sensors-detect suggested to use the k10temp driver,
which your kernel doesn't have. You can try the standalone flavor of
the drivers which I maintain at:
http://khali.linux-fr.org/devel/misc/k10temp/
The accuracy of the CPU internal sensors is limited, but that's still
better than nothing.

hi Eddi,
thanks very much - I had almost forgotten about the topic, but stumbled
across it again a few days ago, so that's very interesting.
I'm not yet familiar with .diff patches, and may welcome a little help.
However, let me try to find out on my own first..
thanks & regards -
Karsten

hello Eddi,
I'm ready for two questions ;-)
.diff / patch looks simple, and I also found i2c-amd756-s4882.c - however:
- the diff file actually describes the patch to be on top of i2c-piix4.c?
- if I'd compile the patched file, would that give me a standalone driver?
thanks for your help -
Karsten

I suggest you:
mkdir ~/piix4-n36l
cp [yourlinuxtree]/usr/src/linux-source-2.6.32/drivers/i2c/busses/i2c-piix4.c
~/piix4-n36l/
cp ~/Downloads/Makefile ~/piix4-n36l/
cd ~/piix4-n36l/
patch -p1 < proliant-microserver-n36l.diff
make
you will have your new module inside ~/piix4-n36l/
rmmod i2c-piix4
insmod ./i2c-piix4.ko
insmod ./i2c-piix4-n36l.ko
insmod w83795 (you should already build separately)
sensors
regards Eddi.
I hope an answer from Jean... I'd like if this patch may be inserted
in mainstream linux with the necessary adjustment..

hello Eddi,
Success!
Thanks for the detailed steps. This all works as described, at least as
far as the 'sensors' output is concerned. With the respective modules, I
get all the measurements you're listing! (See attached.)
'i2cdetect -l' will however not produce any output for whatsoever reason.
The next thing I'd like to find out is how to load the modules
automatically in a clean / kernel-upgrade-proof way..
thanks and regards -
Karsten

hello Eddi,
a less-than-welcome update:
at least when the three modules i2c-piix4.ko, i2c-piix4-n36l.ko,
w83795.ko are loaded, a restart (sudo shutdown -r now) of my N36L
fails, the system does not come up until I do a complete power cycle.
I'll have to look more closely at this, once I have physical access to
the box again.
regards -
Karsten

Well... I noticed this too... I have to investigate...
perhaps I wrong masks on rewriting adresses... I don't know very well
C programming..
I hope Jean Delvare can help us in adjusting mask programming...
Do you get sensors working?

Hi Karsten,
about the complete power cycle issue:
While testing I had same problem like you... I had to remove power
cord to get my server back...
Now I tried a soft "reboot" and I get any issue..
So my patch seems to be fully working and I'd like to know how to
commit into mainstream.
I think may be useful for other pc based on same chipset like ours.
Regards,
Eddi

1) Don't top-post. Your e-mail may otherwise be ignored.
2) There is conflicting information if your patch is causing trouble
or not. Please clarify if and when a reboot fails, and what you changed
to solve the problem.
3) This is an I2C multiplexer. Provide a patch which introduces an I2C
multiplexer driver.
4) Read and follow Documentation/hwmon/submitting-patches for submitting
your patch.
Thanks,

Hi,
It seems that you have kernel configuration for HP Proliant Micro N36L :)
If so can you please send it to me? I am a junior Gentoo user and I am
struggling a lot of troubles in compilation of kernel best suited for N36L
:)
Regards,
Marcin

I don't know who you thought you were taking to, but this is a mailing
list.

:) yes I know - I thought that my message will reach Karsten finally :)
Maybe someone else than Karsten has N36L HP Proliant and will provide me

Marcin
