 Posted: Wed Jan 27, 2010 1:05 pm Post subject: lm sensor for AMD K10 CPU not working correctly |
 |
|
I'm trying to lm sensor to read my AMD K10 (Phenom II X3) cpu temp sensor. On the lm sensor site it lists the driver for download in which I did and installed.
However when issuing the sensors command I get back:
| Code: | localhost one # sensors
k10temp-pci-00c3
Adapter: PCI adapter
|
I know on the Lm Sensor wiki it states:
| Quote: | | (2009-12-06) Embedded sensors are known to be unreliable on the DR-BA, DR-B2, DR-B3, RB-C2 and HY-D0 revisions of the family 10h CPU, which will never be supported. Driver contributed by Clemens Ladisch, reviewed by Jean Delvare. |
Since I did not get the output I was expecting with the sensors command, does this mean I'm scr*wed? |

Only the revision 10h is bad.
You could check yours with cat /proc/cpuinfo | grep -m1 stepping but i don't own an amd and i'm not sure stepping is also use for amd.
considering my output, it seems your sensors is working :/
| Code: | sensors

+5 Voltage: +5.24 V (min = +4.50 V, max = +5.50 V)

Actually, it says there are 5 different revisions of the 10h family that are bad. Skip the grep, the output isn't that long. There should be a separate cpu family entry.
My old Athlon64 lists a stepping, but it is set to 1, so I don't know if it is in use either.

Do I go by the stepping or the familey? The stepping saids 2 and the family saids 16. Would that be 16h which would mean it should work? |

Can you not use the hwmon kernel module? It's in Device Drivers.
I use it like this: | Code: | ~ # echo "$(sed 's/\(..\)\(.\)../\1\.\2/' /sys/class/hwmon/hwmon0/device/temp1_input)C"
45.1C |

DR-BA, DR-B2 and DR-B3 have model number 2, so you don't have those.
HY-D0 has model number 8, so you don't have that one either.
The RB-C* has model number 4, so you may have RB-C2. Post the output of setpci -d 1022:1202 94.L as root, and I should be able to tell you.
Addendum: Oh, and by the way, I'm fairly certain you have family 10h, as all the other output from cpuinfo is in decimal.

I have the same cpu family/model/stepping as you:
| Code: | vendor_id : AuthenticAMD
cpu family : 16
model : 4
model name : AMD Phenom(tm) II X4 925 Processor
stepping : 2 |
I have working k10temp, although I downloaded it from the internet (not using the version in the kernel, because I'm using a weird kernel setup.)
Anyway: | Code: | $ sensors
k10temp-pci-00c3
Adapter: PCI adapter
temp1: +22.5 C
it8720-isa-0228
Adapter: ISA adapter
in0: +0.94 V (min = +0.00 V, max = +4.08 V)
in1: +1.62 V (min = +0.00 V, max = +4.08 V)
in2: +3.28 V (min = +0.00 V, max = +4.08 V)
in3: +2.96 V (min = +0.00 V, max = +4.08 V)
in4: +3.10 V (min = +0.00 V, max = +4.08 V)
in5: +1.33 V (min = +0.00 V, max = +4.08 V)
in6: +3.28 V (min = +0.00 V, max = +4.08 V)
in7: +2.14 V (min = +0.00 V, max = +4.08 V)
Vbat: +3.15 V
fan1: 983 RPM (min = 0 RPM)
fan2: 1036 RPM (min = 0 RPM)
fan3: 0 RPM (min = 0 RPM)
fan5: 0 RPM (min = 0 RPM)
temp1: +30.0 C (low = +127.0 C, high = +127.0 C) sensor = thermistor
temp2: +28.0 C (low = +127.0 C, high = +127.0 C) sensor = thermal diode
temp3: +80.0 C (low = +127.0 C, high = +127.0 C) sensor = thermistor
cpu0_vid: +1.250 V |
dunno if the number's good, but it's a number, so I imagine it's trustable.

That's good to hear. I downloaded mine from the lm sensor wiki since the current kernel in gentoo sources doesn't have it yet. I am compiled it and installed it. The temp doesn't show though..only:
| Code: | $ sensors
k10temp-pci-00c3
Adapter: PCI adapter |
What am I doing wrong? |

dman777,
You should be using the ACPI interface, not the hardware sensor directly.
I have | Code: | vendor_id : AuthenticAMD

+5 Voltage: +5.08 V (min = +4.50 V, max = +5.50 V)
+12 Voltage: +12.44 V (min = +10.20 V, max = +13.80 V)
CPU FAN Speed: 1227 RPM (min = 600 RPM)
CHASSIS FAN Speed: 406 RPM (min = 600 RPM)
CHASSIS FAN 2 Speed: 229 RPM (min = 600 RPM)

The kernel will not load the lm73 driver, or whatever it is as its a very bad thing.
Well, it will but you have to force it on the kernel command line.

Ok. According to the lm-sensors source, your CPU is not affected. So the driver should work.
The line in question in the source is commented with "DDR3". That's not exactly a verbose comment, so I don't know what they mean by that. That the DDR3-supporting chips don't have the problem?
Anyway, if you can't get it to work, you should be able to get the same data through ACPI, as has been suggested.

If you have an ASUS mother board it's fairly easy. If you look under Drivers -> Hardware Monitoring Support right at the bottom of the page there is "ASUS ATK0110" and "STMicroeletronics LIS3* three-axis digital accelerometer". I'm not sure how I found it but the atk0110 seems to work well on my newer M4A87TD EVO board and my old P5Q-E.
I notice that krinn is using the same sensor as well.
From my Phenom system:
| Code: |
atk0110-acpi-0
Adapter: ACPI interface
Vcore Voltage: +1.19 V (min = +0.80 V, max = +1.60 V)
+3.3V Voltage: +3.34 V (min = +2.97 V, max = +3.63 V)
+5V Voltage: +5.10 V (min = +4.50 V, max = +5.50 V)
+12V Voltage: +12.11 V (min = +10.20 V, max = +13.80 V)
CPU Fan Speed: 600 RPM (min = 600 RPM)
Chassis Fan Speed: 405 RPM (min = 600 RPM)
Power Fan Speed: 1577 RPM (min = 600 RPM)
CPU Temperature: +43.0°C (high = +60.0°C, crit = +95.0°C)
MB Temperature: +41.0°C (high = +45.0°C, crit = +75.0°C) |
From my old Core2Duo system: | Code: |
atk0110-acpi-0
Adapter: ACPI interface
Vcore Voltage: +1.10 V (min = +0.80 V, max = +1.60 V)
+3.3 Voltage: +3.30 V (min = +2.97 V, max = +3.63 V)
+5 Voltage: +4.99 V (min = +4.50 V, max = +5.50 V)
+12 Voltage: +12.04 V (min = +10.20 V, max = +13.80 V)
CPU FAN Speed: 1205 RPM (min = 600 RPM)
CHASSIS1 FAN Speed: 0 RPM (min = 600 RPM)
CHASSIS2 FAN Speed: 781 RPM (min = 600 RPM)
CHASSIS3 FAN Speed:2343 RPM (min = 600 RPM)
POWER FAN Speed: 0 RPM (min = 600 RPM)
CPU Temperature: +28.0�C (high = +60.0�C, crit = +95.0�C)
MB Temperature: +35.0�C (high = +45.0�C, crit = +95.0�C) |
NOTE that in both cases the first line of output is the sensor module that the command sensors is getting input from!
later,
joe |

How do I find out the Linux kernel hardware monitoring ACPI driver for a Gigabyte Motherboard ma770t-udp3? I looked on the wiki's but couldn't find any results for this motherboard. I ran sensors-detect and it showed no acpi driver.
EDIT: I don't think there is a acpi driver I can use for my motherboard. Please correct me if I am wrong. Anyways, I got this far:
| Code: | k10ktemp-pci-00c3
Adapter: PCI adapter
temp1: +36.0 C (high = +70.0 C, crit = +72.0 C)
|
It still seems high for this type of CPU with no load going and it being chilly in my apartment. But it's better than the ISA reading.
However I have 2 more cpus I can not get the temps off of. There is no config section in /etc/sensors3.conf for the ktemp-pci-00c3 driver. Can anyone help please? |

Had a look at your MB manual and it looks as if it uses a similar sensor
chip as on mine. So, you would need to include the following option from
the hardware monitoring driver section in your kernel .config
| Code: | | CONFIG_SENSORS_IT87=y |
Additionally, as an example this is output from 'sensors' command on
my system
| Code: | it8718-isa-0228

in6: +4.08 V (min = +0.00 V, max = +4.08 V)

CPU: +37.0 C (low = +0.0 C, high = +60.0 C) sensor = thermal diode

I have had it enabled:
| Code: | | Symbol: SENSORS_IT87 [=y] |
But the it8720-isa-0228 readings can not be right for my cpu temps because they are to high. And the k10temp-pci-00c3 is more realistic but...again...it shows only one cpu.

dman777,
dont know what temp3 represents in your output.
only thing I can say about the CPU temperatures reported from
the it8718 sensors on my board is that they are systematically
(about 7-8 deg.) higher than the k10temp values.
I checked those values against values reported in BIOS and they
are inline with what lm_sensors reports.
edit: BTW, you seem to expect separate temperature readings for
each core, but that is not the case. I am not to sure about the
details, but as far as I understand the k10temp sensor will be
inside the CPU casing (correct term?) or on the die itself, whereas the
temp2 sensor which is reported by lm_sensors (I labeled it CPU myself
via sensors.conf) sits underneath the socket on the MB
edit2: also, if you compare your output with the output from poly_poly-man
than you will find that your values are pretty much inline, couple of degrees
higher though. |
