It is neither. GP11 is a GPIO pin, not supported by the w83627hf driver.

If you are going to ignore all the inputs then it is more efficient to
not load the w83627hf driver at all.


It seems pointless to define a label for an input you ignore a few
lines below. To avoid this kind of issue, I tend to interleave label
and ignore statements in my configuration files.


Likewise, it seems pointless to define a compute statement for an input
you ignore a few lines below.


Here again...


The information provided by the vendor suggests that temp7 is CPU2 and
temp8 is CPU1.


I've dropped the ignore statements for fan inputs, as I seem to
understand fan headers do exist on the board, just you aren't using
them.


You're being too tolerant at least for +3.3V, the ATX standard
specifies a +/- 5%

WDOG_NO_WAY_OUT (3) and WDOG_ACTIVE (0) are the bit numbers, not a mask.
So "data->wddev.status |= WDOG_ACTIVE;" was intended to set bit zero but
it is a no-op.

Re: Nuvoton NCT6776D - AsRock

Guenter Roeck — 2012-05-23T16:39:19

Hi,

that really depends on your kernel version. Try "modprobe w83627ehf".

There is an experimental driver at https://github.com/groeck/nct6775
which you can try as well. It has somewhat improved fan control support.

There is one caveat, though - AsRock uses a GPIO based multiplexer to
map multiple fans into a single fan speed input of the NCT6776F chip. As
a result, you won't be able to see (or control) the speed of all fans.

Nuvoton NCT6776D - AsRock

clement clem — 2012-05-23T16:25:06

Hello to all,

Have a new card *AsRock B75 Pro 3 M* yesterday.

This card uses a new chip *Nuvoton NCT6776D.*

Can we have full support for Lm-Sensors ?

For now only the temperature of my i3 2100 are displayed.


Thank you for your help.

Re: ASUS Sabertooth Z77 / nct6775.ko report

Guenter Roeck — 2012-05-23T15:33:34

Hi Dmitriy,

thanks a lot for the feedback.


The NCT6779D has only five fan sensors, so that is not surprising. Maybe
the other fans are not monitored, there is a second chip to
control/monitor the other fans, or ASUS started putting a multiplexer at
the fan inputs. I hope they didn't, but maybe they learned the wrong
lesson from AsusTek.


No idea what is happening here. The temperature values are taken
directly from the chip registers. ASUS might have a another chip to
monitor other temperatures. Interesting that the PECI input is not
shown; it is used on all other ASUS boards I have seen.


Frankly, I have never seen useful output from this. No idea if it is
even connected.


This is quite common; limits are rarely programmed by BIOSes for some
reason. You'll have to set the limits yourself. The alarms will go away
if the limits are set.

Sounds good. Can you provide output of
"grep . /sys/devices/platform/nct6775.656/pwm*" and "sensors -u" ?

Not much I can do right now. A complete register dump would h

ASUS Sabertooth Z77 / nct6775.ko report

Dmitriy Pinchukov — 2012-05-23T09:37:30

Hi,

Got a new ASUS Sabertooth Z77 mobo recently and found out that lm-sensors didn't support
anything but the core temperatures and also a couple ones from the
'acpitz-virtual-0' device. Trying the trunk version of sensors-detect didn't help.

I then searched and finally found the shiny new 'nct6775' driver. Compiled and loaded it successfully (linux 3.4.0 x86_64):

[ 1082.377370] nct6775: Found NCT6779D chip at 0x290

Felten, Lothar — 2012-05-22T07:13:35

Hi Guenter,


No there was no special reason, the default setting after reset is PGA=8, this
Is probably the best selection. So that should be:
#define INA219_CONFIG_DEFAULT          0x399F  /* default values */

INA2XX_SHUNT_VOLTAGE will then go from -320mV to +320mV, that should be ok.


Best regards,
Lothar

Re: ASRock 970 Extreme3

Guenter Roeck — 2012-05-21T20:15:58

I really don't know details. Supposedly there is a .xml file somewhere
in the ASRock software describing which connector is connected to which
fan, and which fans are multiplexed. The NCT6776F has up to 5 fan
inputs, so theoretically you could get up to 5 fans working. But then I
have no idea which header connects to which fan input, and which headers
are multiplexed.

Re: ASRock 970 Extreme3

James — 2012-05-21T20:07:01

It looks like I can get two fans.
So can I assume that there are two sensors for the 6 connectors and 3 are multiplexed for each sensor?
Is it correct that there are GPIO pins to switch which fan the sensor reads from?

Re: ASRock 970 Extreme3

Guenter Roeck — 2012-05-21T18:11:30

Problem is that ASRock uses a GPIO based multiplexer to connect the
fans. So there is no 1:1 relationship between fans connectors and fan
attributes. The GPIO pins used vary from board to board.

There are some possibilities to support this, such as to modify the
fancontrol script to also support setting gpio pins (if there is a gpio
driver for the given HW), or to somehow implement the necessary support
in the kernel. But those are all not really good solutions, and there
are some questions if it can be made to work reliably in the first
place. The AIDA64 folks tried to implement it but gave up (see
http://forums.aida64.com/index.php?/topic/386-asrocks-fan-controller-sensor-trouble/), which is not a good sign.

ASRock 970 Extreme3

James — 2012-05-21T13:45:53

I use the nct6776-isa-0290
Adapter: ISA adapter

I have 3 fans:
1. The CPU fan (about 3300 RPM)
2. The rear case fan (about 1050 RPM)
3. The front case fan (about 1350 RPM)

Do the fans in Power Supplies typically get monitored?

I have 6 fan connectors:
1. Chassis fan connector (#12 on the motherboard)
2. Chassis fan connector (#15 on the motherboard)
3. Chassis fan connector (#2 on the motherboard)
1. CPU fan connector (#6 on the motherboard)
2. CPU fan connector (#5 on the motherboard)
1. Power fan connector (#10 on the motherboard)

Maybe someone can see a pattern.

1. I plugged the rear case fan in #12
fan1 was 1060 RPM (the rear case fan probably)
fan2 was 3300 RPM (the CPU  fan probably)
other fans reported 0 RPMs

2. I plugged the rear case fan in #2
all fans reported 0 RPM
other fans reported 0 RPMs

3. I plugged the rear case fan in #12 and the front case fan in #15.
fan1 was 1053 RPM (the rear case fan probably)
fan2 was 3316 (the CPU fan probably)
other fans reported 0 RPMs

4. I plugged the rear

With this configuration (PGA=1), the dynamic range for the shunt
resistor voltage is 40 mV. Since we report the value in mV, it does not
provide much value to do that. It might be better to use PGA=8 instead,
for a dynamic range of 320 mV.

Did you have a special reason for selecting PGA=1 ? Otherwise, I think
we should change it to PGA=8.

This is actually wrong; we need to check for I2C_FUNC_SMBUS_WORD_DATA

[PATCH] hwmon: Driver for Nuvoton NCT6775F, NCT6776F,and NCT6779D

Guenter Roeck — 2012-05-21T02:40:31

This driver will replace the w83627ehf driver for NCT6775F and NCT6776F,
and provides support for NCT6779D.

Signed-off-by: Guenter Roeck <linux< at >roeck-us.net>
---

Successfully tested on all supported chips. Time to submit for a first round of
reviews.

A new driver was chosen instead of adding support for NCT6779D to the w83627ehf
driver, since the amount of conditional code was getting too large to manage.
Also, with a new driver it was easier to implement additional fan control
support.

The driver implements a number of non-standard sysfs attributes for fan control.

TODO: Update Documentation/hwmon/nct6775 to list all supported sysfs attributes
(after we have an agreement about the non-standard attributes).
