Support for Intel DG33FB main board?

Hi,

I have a new intel DG33FB mainboard when I run sensors-detect I get the following:
...
Trying family `SMSC'...                                     Yes
Found `SMSC LPC47M182 Super IO Fan Sensors'
     (but not activated)
...
Intel Core family thermal sensor...                         Success!
     (driver `coretemp')

This lets me see the temps of the cores on my q6600 but not
voltages or fan speeds. Are there any plans to support this
main boards further?

sensors version 3.0.2 with libsensors version 3.0.2

Thanks,
Steve

Hmm,

That chip should be detected just fine, can you please try this version of 
sensors-detect:
http://www.lm-sensors.org/browser/lm-sensors/branches/lm-sensors-3.0.0/prog/detect/sensors-detect?format=raw

(All you need to do is safe the one file and make it executable)

And include the output of running this in your next mail?

Regards,

Hans

Patch: libsensors: add support for ACPI bus

Hi All,

The way the new atk0110 driver work it ends up being connected to an "ACPI" 
bus, this patch adds support for this to lm_sensors-3.0.3

With this patch the sensors output on an Asus board looks like this:

atk0110-acpi-0
Adapter: ACPI interface
Vcore Voltage:          +1.45 V  (min =  +1.45 V, max =  +1.75 V)
  +3.3 Voltage:          +3.38 V  (min =  +3.00 V, max =  +3.60 V)
  +5.0 Voltage:          +5.16 V  (min =  +4.50 V, max =  +5.50 V)
+12.0 Voltage:         +12.24 V  (min = +11.20 V, max = +13.20 V)
CPU FAN Speed:         1516 RPM  (min =    0 RPM)
CHASSIS FAN Speed:        0 RPM  (min =    0 RPM)
POWER FAN Speed:          0 RPM  (min =    0 RPM)
CHASSIS4 FAN FAN Speed:   0 RPM  (min =    0 RPM)
CHASSIS2 FAN FAN Speed:   0 RPM  (min =    0 RPM)
CHASSIS3 FAN FAN Speed:   0 RPM  (min =    0 RPM)
CPU Temperature:        +43.0°C  (high = +90.0°C, crit = +125.0°C)
MB Temperature:         +44.0°C  (high = +45.0°C, crit = +90.0°C)

Jean, can you please review this patch, if its ok I can apply it myself.

Thanks & Regards,

Hans

ACPI versus native IC drivers

Hi all,

I've made a good start with reviewing the new ATK0110 driver. And I must say I 
like it. But, there is a big but.

On my Asus M2N SLI Deluxe motherboard, with this driver loaded the two hwmon 
IC's on this board (one superio, one smbus) get hit by both the ACPI and native 
driver code. This is bad, really bad!

Luckily I can fix this by:
1) Using Jean's queued patch for adding acpi resource checks to superio drivers 
from here:
http://khali.linux-fr.org/devel/linux-2.6/jdelvare-hwmon/hwmon-acpi-check-conflict.patch

2) Specifying: "acpi_enforce_resources=strict" on the command line

With this, the native drivers will no longer load. As we have no idea what the 
ACPI code is doing (it might be updating the readings periodically based on a 
timer for all we know). To me this (causing the native drivers to no longer 
load) seems to be the right solution.

The patch adding these checks to the super-io drivers is already queued for 
2.6.29. But that won't help as the current behaviour is to only warn when there 
is a conflict.

So I would like to suggest to change the default setting for 
acpi_enforce_resources from nag to strict. This will only impact smbus 
controllers and superio hwmon code as those are the only 2 using it.

I would personally like to take things even further and believe it would be

Re: [RFC] Asus ATK0110 ACPI hwmon driver

Hi,

I've been working (not finished yet) on reviewing the ATK0110 driver. There is 
one big problem though, it conflicts with direct access to the Ic's as done by 
other drivers, please see my post to the list titled: "ACPI versus native IC 
drivers " for further discussion.

Regards,

Hans

Re: [RFC] Asus ATK0110 ACPI hwmon driver

p.s.

I've also send a patch to the list for libsensors to make it work properly with 
your driver.

SHT15 humidity sensor. Hwmon right place to put a driver?

Dear All,

I'm in the process of cleaning up a driver for the Sensiron SHT15 humidity and
temperature sensor chip.

http://www.sensirion.com/en/01_humidity_sensors/00_humidity_sensors.htm

Before I proceed too far with this I have a couple of general requests for
comment.

Is hwmon a sensible place for this driver?

Whilst it could conceivably be used for hardware monitoring that isn't my
use for it.  I think it is more appropriate here than in the upcoming
industrial I/O subsystem principally because I can't envision a use where
the humidity is changing rapidly enough to require the more complex kernel
ring buffering etc provided there.

The other delightful quirk of this device is that it's bus protocol doesn't
conform to anything remotely standard and hence will be implemented by directly
controlling gpios.

Are people happy with such a low level driver in hwmon?

I think he protocol is very much chip specific so not worth a more general
implementation.  All sensiron's other sensors appear to use more standard
protocols.

If there are any similar gpio based drivers please point them out to me
as an example of accepted practice would save both mine and reviewers time!

Updated fancontrol script

I have updated my improved/extended fancontrol script with the changes
from 0.63 to 0.67 of the "official" script. It's backwards compatible.

http://volker.top.geek.nz/linux/tech/lm_sensors/fancontrol-1.1

Major changes: temperature hysteresis for fan speed, using bash string
functions instead of external programs, changed some ugly programming.
For minor changes see changelog.

Feel free to make this the official script... ;)

Greets,

Volker
