[lm-sensors] reading on-die temperature sensor of AMD A10 5700 processor

Hi,

I just changed the motherboard and the processor while the hard-disk is the
same. I am trying to read the on-die temperature of the AMD A10 5700
processor. Based on the output of "sensors-detect" command, I
installed f71882fg
driver, but the "sensors" command doesn't seem to give me the value of
core-temperature. IN particular, I am getting following output from sensors
command:

----------------------------------------------------------------------------------------------------
f71869-isa-0e80
Adapter: ISA adapter
in0:         +1.68 V
in1:         +1.05 V
in2:         +1.21 V
in3:         +1.22 V
in4:         +1.54 V
in5:         +1.19 V
in6:         +1.19 V
in7:         +1.73 V
in8:         +1.65 V
fan1:          0 RPM  ALARM
fan2:          0 RPM  ALARM
fan3:          0 RPM  ALARM
temp1:       +31.0 C  (high = +85.0 C, hyst = +81.0 C)
                      (crit = +100.0 C, hyst = +96.0 C)  sensor = thermistor
temp2:       +30.0 C  (high = +85.0 C, hyst = +81.0 C)
                      (crit = +100.0 C, hyst = +96.0 C)  sensor = thermistor
temp3:       +48.0 C  (high = +70.0 C, hyst = +68.0 C)
                      (crit = +85.0 C, hyst = +83.0 C)  sensor = thermistor
----------------------------------------------------------------------------------------------------

I am wondering if I have to install lm_sensors package all over again.
Also, I am wondering if "sensors-detect" is up-to-date to detect all
devices/drivers. I guess the fans' rpm readings are 0 because I am using a
custom liquid-based cooling system  instead of regular fan.

Thanks,
Kapil

One of those three is probably from the CPU (wild guess would be temp3).
You might be able to find a correlation by putting the system under load
and observing temperature rises.

If nothing turns it can't measure rpm ...

Thanks for the response Guenter!

I put the system on load and I noticed their value hardly changes. To my
surprise, I ran a benchmark for 3 minutes and none of temp*  values changed
during execution. The highest reported temperature is always 48C.

I was expecting that the internal temperature would have "sensor = thermal
diode" or "sensor = core" as a keyword. I thought "sensor=thermistor" means
the corresponding sensor is on the motherboard and not the internal
die-sensor.

Also, I noticed something that even though I installed and inserted the
driver for f71882fg, when I run "sensor-detect", it still says that "Note:
there is no driver for Fintek F71869FG SUper IO Sensors yet". I thought the
driver name for F71869FG chip is f71882fg (as per
http://lm-sensors.org/wiki/Devices). I installed this driver from here:
http://khali.linux-fr.org/devel/lm-sensors/drivers/f71882fg/ .

I am not worried about the fan-rpm because I intentionally replaced the fan
with a custom heat sink. I mentioned that just so that you ignore those
lines;-).


Thanks,
Kapil

Sure, but who knows if they put a sensor below the CPU for some reason ...

I am not familiar with the A10 CPUs. Are those similar to K10 ?
If so, maybe the k10temp driver works or could be extended to support it.
Can you give it a try ?

If it does not work out of the box, can you send me the output of "lspci -nn" ?

The most recent version of sensors-detect should support it.

Kapil: I believe K10 corresponds to A8 seried, and A10 has Bulldozer
architecture (http://www.cpu-world.com/CPUs/Bulldozer/TYPE-A10-Series.html). I
am not sure how different they are though. I tried K10, but it did not work
out of the box. I am looking into k10temp.c driver now. Also,I am attaching
the output of "lspci -nn" command herewith; you might have to open it using
wordpad for proper formatting..

Kapil: When I used another sensors-detect (probably a newer one) script, I
no longer see the above warning. It recommended me the following at the end
of sensors-detect: "copy prog/init/lm_sensors.init to
/etc/init.d/lm_sensors". I couldn't find the prog/init directory, but I
copied /etc/sysconfig/lmsensors file in to /etc/init.d directory. But, I
still have to insert the f71882fg.ko driver every time I restart the
computer. I couldn't run "make install successfully, as suggested here:
http://khali.linux-fr.org/devel/lm-sensors/drivers/INSTALL .

Your lspci output includes

00:18.3 Host bridge [0600]: Advanced Micro Devices [AMD] Device [1022:1403]

which is supported by the latest k10temp driver. Support was added early last year.
What is your kernel version, and can you switch to a more recent version ?

Thanks,

Kapil: I was trying to avoid updating the kernel because my current kernel is setup for running different type of benchmarks etc. Seems like I can't avoid updating the kernel; I will do it.. 

Just for my understanding: Currently, when I run "sensors" command, I am getting three values (apparently wrong), temp1-3. So, what do you think is happening that is causing these values wrong? And, how is it going to be fixed by updating the  kernel? Although we don't know yet, but, I am hoping that by updating the kernel and loading the k10temp kernel, I would be able to see readings from thermal-diode (core-temperature) along with the current readings from thermal-resistors. 

Thanks,
Kapil

Alternative would be to back-port the k10temp driver from a later kernel. Then you can keep running the old one.

Not wrong; those are probably different chassis and/or board temperatures. Does the BIOS report
any matching temperatures ?

You may be able to compile the k10temp.c driver out of the kernel.  I've
had good success with that in the past.

If you have the kernel build environment, it's pretty straightforward.  You
just need a couple of files.

Kapil: Not sure how to do that. I am already taking the k10temp driver from
here: http://khali.linux-fr.org/devel/lm-sensors/drivers/k10temp/ and
compiling and using it.

Finding that Tmax would be another challenge; but,  I not at that stage yet.

That version should already have support for your chip unless I am missing
something. If you already use it, a newer kernel version will not help.

Do you get any kernel log message when you try to load it ?

Kapil: When I insert the module using: sudo insmod k10temp.ko, I don't get
any message on terminal. However, when I compile ktemp10.c file using make,
I get following warnings; I am not sure if they are acceptable.

k10temp-pci-00c3
Adapter: PCI adapter
temp1:       +4.5 C  (high = +70.0 C, crit = +70.0 C)

I believe temp1 from PCI adapter denotes the core-temperature? But, it is
definitely off by 20-30C; its hard to believe that the temperature would be
4.5C under fan based cooling system. I ran a SPEC hmmer benchmark and
plotted the temperature over time. temp1 seems to change now. I am
attaching the plots herewith.

Please let me know if there is a way to calibrate the core-temperature.

Thanks a lot for your help!

Yes, that is pretty common with AMD chips.

Yes, you'll have to do it in /etc/sensors3.conf. Basically you'll have to
figure out what you think the real temperature is and add it to the raw
temperature provided by the driver.

Re: [lm-sensors] reading on-die temperature sensor of AMD A10 5700 processor

[Dev, Kapil]

[-- Attachment #1.1: Type: text/plain, Size: 4460 bytes --]

Hi,

Sorry for the verbose email. I am trying to read the temperature value as
accurately as possible, that's why.

It is evident that there are some computations happening internally before
these values are reported. Here is what I have to say about the 4.5C
reported value.

I am using A10 5700 APU amd processor. It has bulldozer architecure (
http://www.cpu-world.com/CPUs/Bulldozer/TYPE-A10-Series.html). Bulldozer
architecture corresponds to 15h micro-architecture family  (
http://en.wikipedia.org/wiki/List_of_AMD_CPU_microarchitectures). So, I
looked at the official manual of 15h family
http://support.amd.com/us/Processor_TechDocs/42301_15h_Mod_00h-0Fh_BKDG.pdf).
And, I found the following:

Page 219 and 393 (figure-14) of the document mention that bits 31:21 (11
bits) of the register D18F3xA4 denote the current temperature of the die as
reported by temperature calculation circuit (TCC). The maximum value that
could be represented by 11 bits is 2048 (2047, but ignore this for now) and
they want to translate that to 256. So, I think the magic number 125 is
obtained by computing 256/2048*1000. Line number 66-68 in k10temp.c (as
downloaded from the drivers' link) use 125 as the factor to compute the
value to be reported. I guess the factor of 1000 would be taken care
somewhere else inside the kernel.

It also means that the lowest resolution of reading the temperature is
0.125C, which might mean that we could get a sub-degree resolution in
temperature reading?

I got a little confused about the way temperature-computation is explained
on page 393. The interpretation of D18F3xA4[31:21] seems to be different
based on the D18F3xA4[17:16] bits. Something similar, but not exactly the
same thing, is implemented in k10temp.c in lines 85-90. The value
(D18F3xA4[18:16]) is multiplied by 500 and then 52000 is added to it.
While, on page 393, I see <(CurTmp[10:2]*0.5)-49>. In line 89 of k10temp.c,
the hysteresis is computed as (D18F3xA4[27:24])*500,  i.e. four bits are
used. While on page 393, three bits (equivalent to 0.125*8 = 1C) is used as
hysteresis. Am I understanding things correctly here?

Also, if I want to apply any further correction to the reported raw values,
I guess I just need to put following piece of code in /etc/sensors3.conf
file:

-------------------------------------------------------------
chip "k10temp-*"
     compute temp1 (@+correction),(@-correction)
-------------------------------------------------------------

This should add correction to the temp1 value under PCI adapter alone and
not to the temp1 value under ISA adapter?

Thanks,
Kapil

Adding Clemens to the thread - maybe he can help with the rest. I am not really an expert on AMD CPUs.

Thanks! Does it mean that I can change the k10temp.c to read milli-degree
C. I have always seen integer readings.

It has bulldozer architecure (http://www.cpu-world.com/__CPUs/Bulldozer/TYPE-A10-__Series.html <http://www.cpu-world.com/CPUs/Bulldozer/TYPE-A10-Series.html>). Bulldozer architecture corresponds to 15h micro-architecture family  (http://en.wikipedia.org/wiki/__List_of_AMD_CPU___microarchitectures <http://en.wikipedia.org/wiki/List_of_AMD_CPU_microarchitectures>). So, I looked at the official manual of 15h family http://support.amd.com/us/__Processor_TechDocs/42301_15h___Mod_00h-0Fh_BKDG.pdf <http://support.amd.com/us/Processor_TechDocs/42301_15h_Mod_00h-0Fh_BKDG.pdf>).

The maximum value that could be represented by 11 bits is 2048 (2047, but ignore this for now) and they want to translate that to 256. So, I think the magic number 125 is obtained by computing 256/2048*1000. Line number 66-68 in k10temp.c (as downloaded from the drivers' link) use 125 as the factor to compute the value to be reported. I guess the factor of 1000 would be taken care somewhere else inside the kernel.

No. The value in the sysfs attribute file is already reported in milli-degrees C;
this is what the driver prints. The sensors command converts it into degrees C.
If the sensors command reports 4.5 degrees C, the sysfs attribute value is 4500.

These two bits should always be 00; Linux never tries to write the

I see. It means  that D18F3xA4[31:21] always denotes the Tctl temperature
(control temperature). Where, Tctl <= Tmeasured <= Tctl+TmpMaxDiffUp. The
value of TmpMaxDiffUp is between 0 and 9C depending on the value of two
bits, D18F3xA4[6:5]. Should I check the value of these two bits, or did you
already figure that out? So, line 68 is really what I should worry about:

return sprintf(buf, "%u\n", (regval >> 21) * 125);

 I installed ubuntu 12.04.02 LTS on another hard-disk and installed
lm-sensors on that. I did not install the driver from
http://khali.linux-fr.org/devel/lm-sensors/drivers/k10temp/k10temp.c manually,
because it was already installed in the kernel. I noticed, that the
reported temperature was very erratic, changing anywhere between 3 C and
30C, even when there was no workload running on the cpu.

Sorry, it was a typo from my side. If I understand it correctly, the
implementation is such that it reports following values:
1) Highest temperature = 70; due to "return sprintf(buf, "%d\n", 70 * 1000
in c-code);"
2) Critical temperature = mostly 70; due to D18F3x64[22:16]*0.5+52 (value =
((regval >> 16) & 0x7f) * 500 + 52000; in c-code), which kind of means
that D18F3x64[22:16]
is mostly fixed to 36?
3)  Hysteresis value: From  D18F3x64[22:16]*0.5+52 -
D18F3x64[22:16]*0.5  (value
-= ((regval >> 24) & 0xf) * 500; in c-code). Is the value of D18F3x64[22:16]
fixed or it changes based on some condition?

Again, thanks a lot! As I said, I am trying to compute the temperature
values as accurately as possible because my project involves calibrating
the die-temperature values against other measurements

All four fields in bits 0..12 can make the shown temperature value
slightly out of date.  This is intentional to smooth out the
measurements.

No, it is between 0 and 9.

Over time, the average value should be accurate.

No, between 3 and 30.

When the CPU is mostly idle, even small wakeups for interrupts will
result in rather large relative changes in power consumption and,
therefore, power dissipation.

This is not the highest possible value; temp1_max is the highest value
during normal operation.  On AMD CPUs, this is the point at which the
CPU fan should run at 100 % (of TDP).

This register has whatever value the BIOS has written into it.

It changes when the BIOS (or somebody else) writes to it.

Did you read section 2.11.1?  It says:
| Tctl does not represent a temperature which could be measured on the
| die or the case of the processor. Instead, it specifies the processor
| temperature relative to the maximum operating temperature

The maximum operating temperature is defined as 70, but does not
correspond to a known absolute temperature.

This temperature sensor is designed to control the CPU fan; it is _not_
intended to result in a value that can be shown to the user in a way
that makes much sense.

Yes, I read it and I understood it in a way that Tctl is changed dynamically to track Tmeasured. Although, the scale of Tctl is weird, but I still thought these final values were still in degree C. I think that you are saying that the units of final reported values are not deg-C. I will read the document again, more carefully this time. 

I had following understanding:
Based on page 220, fig-14, max operating T and Tctl_max are the same. Also, the temperature of the part is [Tctl_max - Tctl] below the max operating T, which is the same as Tctl_max. So, it kind of means that Tctl itself is the temperature of the part (without the slew-rate control). Thats why I assumed that TmpMaxDiffUp was between 0C and 9C because I assumed that Tctl had units of degree C. I thought that when they say the temperature of the part or measured temperature, they mean the die-tmperature coming through temperature calculation circuit (TCC). But, it seems like thats the wrong understanding.

Little bit detail of what I intend to do:
I have a high-end IR camera which I use to take real-time high resolution image of the processor. Unfortunately, I need to calibrate the camera itself against true temperature. I need two temperature-points at which the temperature reported by the sensor is correct; using those two points, I might be able to calibrate the camera in the entire range and could potentially figure out the discrepancy in reported temperature at every other temperature reading. I am not sure if I am clear; if not, please let me know. 

Also, I have come to know that these sensors are more accurate at higher temperature; but, this information is not sufficient enough. I am looking for those temperature values at which the reported value is the same as the absolute temperature of the die. I thought this value is 70C for AMD processor. If those values are high, I could achieve them by controlling the cooling of the processor. In my experiments, I remove the fan and use liquid cooling with controlled fluid-temperature.

Kapil

Indeed they are not.  The final reported values do not have any unit.

The only known facts about the scale of these temperate values are:
1) Higher values corresponds to higher temperatures; and
2) at a value of 70, a fan designed for TDP must run at 100 %.

> I need to calibrate the camera itself against true temperature.

This is not possible with the CPU sensor.
