[lm-sensors] strange output values from W83627HG chip

[lm-sensors] strange output values from W83627HG chip

[Jurijs Petrovs]

Hi!

I'm just got new server based on Supermicro X7DVA-E mainboard with
W83627HG chip.

Successfully loaded kernel driver w83627hf (using 2.6.20-rc2 kernel
with lm-sensors 2.10.0) and noticed that BIOS values of sensors
differs from lm-sensors output results. 

These are values from BIOS: 

PECI Agent1: 21 C 
PECI Agent2: 18 C 
System Temperature 24 C 

FAN1: 3708 RPM 
FAN2: 3648 RPM 
FAN3: N/A 
FAN4: 1232 RPM 
FAN5: 1260 RPM 
FAN6: N/A 

Vcore A: 1.228 V 
Vcore B: 1.232 V 
-12V -12.809 V 
P1V5 1.488 V 
+3.3V 3.328 V 
+12V 12.192 V 
5Vsb 5.016 V 
5Vdd 4.848 V 
P_VTT 1.194 V 
V_bat 3.152 V 
And these ones I’m getting from linux tool
“sensors”: 

w83627hf-isa-0290 
Adapter: ISA adapter 
VCore 1: +3.36 V (min = +1.34 V, max = +1.49 V) ALARM 
VCore 2: +3.41 V (min = +1.34 V, max = +1.49 V) ALARM 
+3.3V: +0.91 V (min = +3.14 V, max = +3.47 V) ALARM 
+5V: +5.08 V (min = +4.76 V, max = +5.24 V) 
+12V: +4.50 V (min = +10.82 V, max = +13.19 V) ALARM 
-12V: -6.93 V (min = -13.18 V, max = -10.80 V) ALARM 
-5V: -1.98 V (min = -5.25 V, max = -4.75 V) ALARM 
V5SB: +5.75 V (min = +4.76 V, max = +5.24 V) ALARM 
VBat: +2.14 V (min = +2.40 V, max = +3.60 V) ALARM 
Fan1: 0 RPM (min = 3013 RPM, div = 2) ALARM 
Fan2: 0 RPM (min = 2657 RPM, div = 2) ALARM 
Fan3: 0 RPM (min = 2657 RPM, div = 2) ALARM 
Temp1: +29°C (high = +50°C, hyst = +45°C) sensor thermistor 
Temp2: +32.5°C (high = +80°C, hyst = +75°C) sensor thermistor 
Temp3: +33.0°C (high = +80°C, hyst = +75°C) sensor thermistor 
vid: +1.419 V (VRM Version 11.0)
alarms: 
beep_enable: 
Sound alarm enabled 
Very strange values in almost all sensors (voltages, temperature) and
especially in Fan speeds. I could not get any value except zero. 

Some ideas what I’m doing wrong? 

Thanks in advance!

Yes because you have on your board another chip, which is actually used -
W83793. Just modprobe w83793 driver, and report if it is OK. And please use the
lm-sensors version 2.10.1 which has support for this chip, the sensors-detect
from 2.10.1 should find it.

Please report back the output of sensors command, and dont forget to update your
sensors.conf

[lm-sensors] strange output values from W83627HG chip

[Jurijs Petrovs]

Hi!
First, happy new year to all!

Many thanks for your advice, Rudolf!
I loaded correct driver w83793 and updated lm-sensors. Right after
that I saw correct values from sensor command. As you asked, here is
report  of these values (I just corrected computing formula for
"-12V" sensor and set ignore to unused FANs):

Very strange that motherboard specification on the original
manufacturer site shows Winbond W83627HG chip. Is it error on site or
my own misunderstanding of docs?

http://www.supermicro.com/products/motherboard/Xeon1333/5000V/X7DVA-E.cfm

And where I can get _right_ description of temperature sensors for
temp3-temp6 sensors?

Thnaks for help!

Looks like temp4 is not connected.

In manual, (intel usually creates a technical document about MB and there is
written where sensors are)

I just checked and it is not there... But they may used what was recommended by
Winbond

temp5-temp6 are thermistors placed somewhere on the board. (Is 16C likely?)
temp1-temp4 could be disabled, monitored through PECI or analog - thermal diode.

Please go to:

cd /sys/class/hwmon/hwmon0/device
cat name
cat temp?_type

It will show the actual type. You could also RTFM in
kernel/Documentation/hwmon/w83793 ;)))

Please provide the output so we know what is what

Jean,

This reminds me... This would be great case for the tempX_label file, so it will
show the string "None" "Thermal diode" "PECI" ...

Do you like that idea?

Ok.
Here are results of `cat /sys/class/hwmon/hwmon0/device/temp?_type` :

6
6
6
6
4
0

Following kernel docs, temp6 is disabled, so I put ignore line in sensors.conf for it 
now. Also, as I read manual for motherboard and tried to run superdoctor utility, I 
found that temp5 is System Motherboard temperature (36C looks like true) 

But why do you suggest to disable temp1-temp4? Yes, they are monitored through 
PECI and I can use coretemp driver instead?

These are values from coretemp drivers (I have 2 CPU with 2 cores)
cat /sys/class/hwmon/hwmon[1,2,3,4]/device/temp1_input 
28000
28000
24000
27000

Quote from Supermicro FAQ: 
"Q: PECI 1 and 2 have correct readings of 34 and 38 but PECI 3 and 4 show 0 
readings"
"A: The reason is that the current Woodcrest CPU (Intel 51xx series CPU) only has 
one PECI Agent for each CPU and that is why you see only two readings."

This answer explains my strange values in temp3-temp4. 
So, am I right to use coretemp driver values instead of temp1-temp4 ones?

Also, I can't found anywhere in docs how to show coretemp values from sensors 
output! Now I can read them only from sysfs.

Sory for too many questions! :)
Thanks in advance!

They are all PECI

> 0

Hmmm question is what to do in the driver when temperature channel is disabled
We may:

1) not create the tempX_input file
2) when disabled remove tempX_input file
3) do nothing

Now we do 3)

Good. You have there Windows too? Or it runs linux?

I do? Ah that was just a guess that there is 0 (multi choice enumeration) Sorry
for that

Hmm we should really push the driver to kernel :/

But we see 3 of them...  temp3 is not so bad... I don't know what happen with
the chip if PECI fails. (does not exist)

Yes you may use them instead.
