[lm-sensors] Gigabyte GA-D525 core temps N/A?

[lm-sensors] Gigabyte GA-D525 core temps N/A?

[everythingsfree]

Hi,

I'm running Ubuntu Server 10.4 LTS (64 bit) on a Gigabyte GA-D525 
board and have downloaded, built and installed the latest version of lm-
sensors (using 'sensors -v' it reports 'sensors version 3.3.0 with 
libsensors version 3.3.0'), as far as I can tell I've done this 
correctly.

I ran 'sensors-detect' and answered all of the questions 
and let it do its thing.

On checking what gets reported through 
'sensors' I get the following which appears to be failing to report the 
temperatures of the cores  (I also wonder why it's attempting to report 
four when it's only a dual core processor) although I do get some 
temperatures at the bottom:


coretemp-isa-0000
Adapter: ISA adapter

Core 0:           N/A  (crit = +100.0°C)

coretemp-isa-0001
Adapter: 
ISA adapter
Core 1:           N/A  (crit = +100.0°C)

coretemp-isa-
0002
Adapter: ISA adapter
Core 2:           N/A  (crit = +100.0°C)


coretemp-isa-0003
Adapter: ISA adapter
Core 3:           N/A  (crit = 
+100.0°C)

it8720-isa-0290
Adapter: ISA adapter
in0:          +1.10 V  
(min =  +0.00 V, max =  +4.08 V)
in1:          +1.52 V  (min =  +0.00 
V, max =  +4.08 V)
in2:          +3.31 V  (min =  +0.00 V, max =  +4.08 
V)
in3:          +2.98 V  (min =  +0.00 V, max =  +4.08 V)

in4:          +3.09 V  (min =  +0.00 V, max =  +4.08 V)
in5:          
+4.08 V  (min =  +0.00 V, max =  +4.08 V)  ALARM
in6:          +4.08 V  
(min =  +0.00 V, max =  +4.08 V)  ALARM
in7:          +2.18 V  (min =  
+0.00 V, max =  +4.08 V)
Vbat:         +3.06 V
fan1:        3857 RPM  
(min =    0 RPM)
fan2:           0 RPM  (min =    0 RPM)
temp1:        
-55.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor

temp2:        +64.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = 
thermistor
temp3:        +30.0°C  (low  = +127.0°C, high = +127.0°
C)  sensor = thermal diode
cpu0_vid:    +1.850 V

From what I 
understand 'coretemp' is reporting the core temperatures and the other 
stuff is from'it87' (these are also in '/etc/modules')

I also noticed 
that someone else has reported what appears to be a similar or the same 
problems with this board back in April (http://lists.lm-sensors.org/pipermail/lm-sensors/2011-April/032332.html
, oddly they only got two core temperature reading attempts.

Hopefully 
someone can respond and help me out, no one appears to have replied to 
the other posting unfortunately.  I'm willing to try out any code 
changes and run tests that may be required.

Thanks
Dave

Your CPU may support hyperthreading. Older versions of the driver 
don't take this into account.

Newer kernel version, most likely.

No idea what is going on. You might try to build and compile the latest
version of the coretemp driver to see if it improves the situation.
You can download it from http://roeck-us.net/linux/drivers/coretemp/.

Can you provide output of /proc/cpuinfo ?

Thanks,
Guenter

It's an Intel Atom D525 which 
according to the specs does support hyperthreading, I did think that 
may have been why.

Sadly that may be where my knowledge of building things under Ubuntu 
(or any Linux) falls somewhat flat.  I'll take a look on-line for how 
to do it but if you can quickly let me know that'll make the turn 
around faster.

may help. It's not Ubuntu-specific, but the Debian hints may work.

Download the two files into some directory, then run "make" in it.
You may have to install the linux-headers package first, and possibly
the C compiler (gcc) and/or make.

After make succeeds, run "sudo make install" followed by "sudo modprobe -r coretemp"
and "sudo modprobe coretemp".

Something like

mkdir coretemp
cd coretemp
wget http://roeck-us.net/linux/drivers/coretemp/coretemp.c
wget http://roeck-us.net/linux/drivers/coretemp/Makefile
sudo apt-get install make 				# if necessary
sudo apt-get install gcc 				# if necessary
make
# Note: make will likely fail and tell you the missing headers, such as 
#make: *** /usr/src/linux-headers-2.6.35-25-server: No such file or directory.  Stop.
#make: *** [modules] Error 2
sudo apt-get install linux-headers-2.6.35-25-server	# or whatever linux version you run
make
sudo make install
sudo modprobe -r coretemp
sudo modprobe coretemp

Thanks Guenter & Jean for the replies.

I found this web page with some 
info and was following that (but just used the Makefile as downloaded):


https://wiki.ubuntu.com/CoreTemp
That checked and updated a few things 
plus downloaded other (it covered everything Guenter had suggested) but 
I still get errors:

I 
would have assumed that 'MSR_IA32_TEMPERATURE_TARGET' would be defined 
in a header file and that that would be in the 'linux-headers-2.6.32-24-
server' package that was downloaded, perhaps not?

Any suggestions?  
I'll keep looking on-line...

Thanks,
Dave

The build worked for me with linux-headers-2.6.32-25-server.
Can you update your system to the latest kernel version and try again ?
It should be 2.6.32-32 as far as I can see.

Thanks,
Guenter

Sorry, I got that wrong; it was 2.6.35-25, not 2.6.32-25.

Wel'll have to add the missing defines manually. I'll send you an update later tonight.

FWIW my own backport of the coretemp driver at:
http://khali.linux-fr.org/devel/misc/coretemp/
includes compatibility quirks which may help. I don't know if Guenter's
has the same.

I've attached my compatibility patch for your reference. But it's
probably easier for Dave to just use my driver.

No, my version doesn't have any compatibility stuff, so using your
driver may be a better choice (and save me some time).

Re: [lm-sensors] Gigabyte GA-D525 core temps N/A?

[everythingsfree]

Guenter & Jean, thanks for the continued help.

I got slightly bogged 
down yesterday attempting to upgrade my install - I tried 'apt-get 
update' which downloaded a few things but didn't fix the problem so I 
then tried 'apt-get upgrade' (I'm not sure on the difference between 
the two...) which downloaded even more and then got into trouble, 
ending with a segmentation fault!  I rebooted and continued but got 
more issues and had to stop as it was getting late.

I've since resumed 
and managed to get where I am now with what I hope is a fully upgraded 
install but I still get the same compile errors.

So, I've grabbed 
Jean's file and followed Guenter's instructions to build and install 
those, all went well.  On running 'sensors' I still get 'N/A' for the 
core temps but at least I only get two:

coretemp-isa-0000
Adapter: ISA

Core 0:           N/A  (high = +80.0°C, crit = +100.0°C)

C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor

thermal diode
cpu0_vid:    +1.850 V


Any further thoughts?

Btw, how 
do you apply a patch file?

Thanks,
Dave

Maybe your CPU doesn't support the temperature register ? I don't really

Usually you would use the "patch" command. Idea, though, was that you
would just use Jean's driver; he sent the patch to show the differences
to the upstream version.

Actually this reminds me of similar issues that were reported before and
never solved:
http://lists.lm-sensors.org/pipermail/lm-sensors/2010-January/027716.html
http://lists.lm-sensors.org/pipermail/lm-sensors/2010-September/029501.html
http://lists.lm-sensors.org/pipermail/lm-sensors/2010-November/030521.html

The errors look slightly different because of older versions of
lm-sensors, but the problem is the same: the MSR_IA32_THERM_STATUS
register fails to return a valid value.

It would be interesting to check from user-space and see what the raw
MSR read returns. You'll need the msr kernel driver, as well as the
msr-tools package.

# rdmsr -p 0 -x 0x19c
# rdmsr -p 1 -x 0x19c
# rdmsr -p 2 -x 0x19c
# rdmsr -p 3 -x 0x19c

Re: [lm-sensors] Gigabyte GA-D525 core temps N/A?

[everythingsfree]

Jean,

I've installed and set-up msr-tools after a quick look on-line 
on how to do so ('sudo apt-get install msr-tools' followed by 'sudo 
modprobe msr', let me know if that's missing something) and I get the 
following for your commands:

$ sudo rdmsr -p 0 -x 0x19c
8600000
$ sudo 
rdmsr -p 1 -x 0x19c
8630000
$ sudo rdmsr -p 2 -x 0x19c
8630000
$ sudo 
rdmsr -p 3 -x 0x19c
8600000

Hope that helps.

Cheers,
Dave

The valid reading bit (31) is indeed never set, which is why the driver
returns an error (and in turn "sensors" returns N/A.)

The readings themselves don't look good anyway. 0x60 and 0x63 would
translate to offset values of 96 and 99, respectively. With a critical
limit at 100°C, that would lead to readings of 4°C and 1°C,
respectively, which is obviously incorrect.

I am wondering if maybe the valid reading bit gets cleared when the
measured temperature is too low, because it is known that the
reliability and accuracy of the digital thermal sensor get very poor
when too far below the critical limit. Durgaross, Fenghua, do you know
if this is the case? The CPU in question is an Atom D525 (family 6,
model 28, stepping 10).

Dave, please try putting as much load as possible on your CPU (e.g. by
running "md5sum /dev/zero" 4 times in parallel), and then run the rdmsr
commands again, every 20 seconds or so, for 5 minutes. It will be
interesting to see if the readings decrease (meaning higher
temperatures over time) and if the valid reading bit will get set at
some point.

When done, don't forget to kill the md5sum commands ;)

Re: [lm-sensors] Gigabyte GA-D525 core temps N/A?

[everythingsfree]

Hi Jean,

I did as you ask but the values being returned were no 
different to those before.  I checked with 'top' to make sure the CPU 
was being loaded and sure enough there were four 'md5sum' processes 
running at 100%, it also reported that the 'Cpu(s)' were around 92%us 
(oddly it only reported one line for the CPUs when I expected two lines 
for each core at least, perhaps even four lines given hyper-
threading).  I let it run for ten minutes just to be sure.

Hope that 
helps.

Cheers,
Dave

Hi Dave,

OK, I have no other idea then. Hopefully the Intel folks can help.

With regards to "top", you can switch to multi-cpu display by pressing
"1".
