acpi thermal module


why doesn't my system temprature show in /proc/acpi/thermal ?
why is /proc/acpi/thermal empty ?

i got generic kernel package 2.6.* from slackware current distribution
after i load modules ac then processor then thermal , i do
ls /proc/acpi/thermal and it is empty .

The Linux kernel doesn't provide ACPI support for all motherboards.
Most that I've tried it on, with the exception of laptops, don't show
anything. Try lm_sensors in Slackware 11.0:
Code:
mingdao@silas:~$ less /server2/ftp/pub/Linux/Slackware/slackware-current/slackware/PACKAGES.TXT
PACKAGE NAME:  lm_sensors-2.10.0-i486-3.tgz
PACKAGE LOCATION:  ./slackware/ap
PACKAGE SIZE (compressed):  292 K
PACKAGE SIZE (uncompressed):  1070 K
PACKAGE DESCRIPTION:
lm_sensors: lm_sensors (hardware monitoring package)
lm_sensors:
lm_sensors: lm_sensors provides tools for monitoring the temperatures, voltages,
lm_sensors: and fans of Linux systems with hardware monitoring devices.  Included
lm_sensors: are text-based tools for sensor reporting, and a library for sensors
lm_sensors: access called libsensors.  It also contains tools for sensor hardware
lm_sensors: identification and I2C bus probing.
lm_sensors:
lm_sensors: IMPORTANT NOTE:  If you have a Thinkpad, please read the warnings in
lm_sensors: the README.thinkpad file.  lm_sensors has been known to cause damage
lm_sensors: to some Thinkpads.
It shows much more than just CPU temp. Here's a screenshot.

it87

yes i run sensors and gkrellm .
i got it8712 chip so the module it87 is loaded
and sensors give three temperatures :
Code:
M/B Temp:    +33C  (low  =   +15C, high =   +40C)   sensor = thermistor   
CPU Temp:    +29C  (low  =   +15C, high =   +45C)   sensor = thermistor   
Temp3:       +27C  (low  =   +15C, high =   +45C)   sensor = diode
but bios read CPU Temp 55C not 29C , maybe there
is specail meaning for '+' , and it is not absolute value ?

I don't know much about the app. Mine reports:
Code:
+5V:       +5.11 V  (min =  +0.00 V, max =  +3.71 V)       ALARM  
+12V:     +11.25 V  (min =  +2.55 V, max =  +1.03 V)       ALARM  
-12V:      +1.13 V  (min =  +2.11 V, max =  -6.36 V)       ALARM  
-5V:       +5.10 V  (min =  -5.75 V, max =  +0.83 V)       ALARM  
V5SB:      +5.54 V  (min =  +4.19 V, max =  +2.61 V)       ALARM  
VBat:      +0.00 V  (min =  +1.14 V, max =  +0.00 V)       ALARM  
fan1:     3590 RPM  (min = 21774 RPM, div = 2)              ALARM  
fan2:     3879 RPM  (min = 2812 RPM, div = 2)                     
temp1:       +28C  (high =    +4C, hyst =   +14C)   sensor = thermistor   ALARM   
temp2:     +38.5C  (high =   +80C, hyst =   +75C)   sensor = thermistor           
alarms:   Chassis intrusion detection                      ALARM
beep_enable:
          Sound alarm enabled

eeprom-i2c-0-52
Adapter: SMBus Via Pro adapter at 0400
Memory type:            DDR SDRAM DIMM
Memory size (MB):       512

eeprom-i2c-0-51
Adapter: SMBus Via Pro adapter at 0400
Memory type:            DDR SDRAM DIMM
Memory size (MB):       512

eeprom-i2c-0-50
Adapter: SMBus Via Pro adapter at 0400
Memory type:            DDR SDRAM DIMM
Memory size (MB):       1024
I assume temp1 is case, temp2 is CPU, and all values are correct.

Is there any other application which can show your thermal information on your desktop besides gkrellm?

Or perhaps by looking at /proc/acpi/thermal is also working?

Thanks

I know this is silly, but did you try
Code:
cat /proc/acpi/thermal_zone/THRM/temperature
If it says it doesn't exist, then you need to recompile your kernel to <include> those values, not as modules...

really

i have compiled 2.6.18 and included acpi as modules

are you sure that by including them staticly they
would produce different functionality ? it doesn't make sense .

i will try to compile like you siad but it is most
likely that kerenel acpi simply doesn't support my GA-7n400s-l
when i had EP-8khal+ i could read /proc/acpi/thermal_zone/...
without problems , and it showed same temperature as bios

Mine didn't work either until I compiled statically. Then it worked fine.

yeah, i think i have the same problem (compiling as modules) because when i looked at /proc/acpi/thermal_zone, it's empty
