Re: Processor Temp

Is there a way to get the processor temp via terminal in OS X?

I doubt it

There used to be a function called something like getCoreProcessorTemperature() in pre-OSX,
however I think it has been deprecated ( it was commented out in the header ).

The reason it doesn't appear ( if my memory serves me correct ) is that not all PPC support
manual calibration of the TAU, I can only assume that the chip handles it, but I could be wrong.

I'd like to script some method to record the processor temp of my old
beige G3.

Well I had it working on a G3 and all my TAU documentation refers to the G3 ( 750L I think ).

If you can avoid doing it I would, the words "DANGER DANGER POISON" should be written all over it.

You would have to do it in kernel space as you would have to be in supervisor mode.

It is not as simple as saying to the chip "How hot are you?" you set a pair of interrupts
( if I remember correctly, which I probably don't ) and pick a low value, hoping to be interrupted
straight away, you increase the value until it no longer interrupts, and then you should have your value.

There is a kext in Jaguar called "AppleCPUThermo.kext", however I don't know what it does.

I write all this so that someone might put me straight or fill in the gaps.

There are also a couple of apps that might help

though I do not know if they support G3, or log to a file.
