ACPI question

skottish · 2006-11-20 02:54:42

I just installed a new motherboard, reinstalled Arch, and I no longer have entries under /proc/acpi/thermal_zone. acpid is running, and I have the acpi files installed. Does anyone have any idea why it's not working?

It just depends what your motherboard and processor supports. Evidently your new board either doesn't support thermal_zone, or the relavent modules for your board don't support it yet, or it's a module bug.

That's kind of what I thought. It's a drag because I run processes that swallow up both cores of my machine for hours at a time. It's nice to be able to watch what's happening there. Thanks all the same.

Have you looked at lm_sensors? On my Athlon64, thermal_zone doesn't work, but lm_sensors gets the CPU temperature no bother.

I installed it, but I forgot all about it. What do I need to do to get it to work?

Run "sensors-detect", it'll take care of your configs. Then you'll need to run the "sensors" daemon (either through /etc/rc.conf or manually). Then if you run "sensors", it'll give you your hardware stats. Here is what mine says just now so you get an idea of what you get:

[chris@marbles ~]$ sensors
it8712-isa-0d00
Adapter: ISA adapter
VCore 1:   +1.20 V  (min =  +1.42 V, max =  +1.57 V)   ALARM
VCore 2:   +4.08 V  (min =  +2.40 V, max =  +2.61 V)   ALARM
+3.3V:     +3.31 V  (min =  +3.14 V, max =  +3.47 V)   ALARM
+5V:       +5.11 V  (min =  +4.76 V, max =  +5.24 V)   ALARM
+12V:     +13.12 V  (min = +11.39 V, max = +12.61 V)   ALARM
-12V:      +3.93 V  (min = -12.63 V, max = -11.41 V)   ALARM
-5V:       +4.03 V  (min =  -5.26 V, max =  -4.77 V)   ALARM
Stdby:     +6.85 V  (min =  +4.76 V, max =  +5.24 V)   ALARM
VBat:      +3.20 V
fan1:     1973 RPM  (min =    0 RPM, div = 4)
fan2:     1308 RPM  (min = 3013 RPM, div = 8)          ALARM
fan3:       -1 RPM  (min = 3000 RPM, div = 2)
M/B Temp:    +27°C  (low  =   +15°C, high =   +40°C)   sensor = thermistor   ALARM
CPU Temp:    +27°C  (low  =   +15°C, high =   +45°C)   sensor = thermistor   ALARM
Temp3:      +128°C  (low  =   +15°C, high =   +45°C)   sensor = disabled

As you can see, Temp3, -12V and -5V are a little unrealistic. You can disable things like that in the configs, I just never bothered. And I never bothered to set up the alarm limits. And it has my CPU and mobo temps backwards (not that you can tell really), but that can also be changed in the configs. All in all, it's quite cool

That's perfect. Thanks a bunch.

You're welcome.
