cputemp 1.0 Released For Linux Thermal Monitoring

[schmidtbag]

lm_sensors read from I2C and other buses to communicate directly with the integrated circuit and stuff.
cputemp mentioned in the article reads from ACPI.

Right I get that much but what makes ACPI better for reading temperatures? I pretty much got the impression that ACPI was more revolved around keeping your computer power efficient and quiet. While temperatures take a big part in that, I don't see why power control couldn't just use I2C sensors.

If there wasn't a native way to read the temps, then you could use ACPI for it. But since there is a superior native interface...

[tettamanti]

Big WTF here...
The program just uses the legacy interface for ACPI thermal zones. Newer kernels expose the TZ using the standard hwmon interface (i.e. /sys/class/hwmon) and readings are picked up automatically by libsensor along with the ones from native interfaces.

I've done a C port of the tool. You can find it at https://github.com/ifoo/ccputemp.

Now were talking!

Thanks a bunch!

I don't know.
I thought maybe that with I2C you have have a special driver for every sensors, and that with ACPI you can just call the ACPI and get it without having special drivers for every sensor.

wow, now I can find it, it appeared from some minutes.
but it didn't compile:

Chuck Norris may be able to install software system wide as a regular user, but you need to be root to do that.
