Subject:  [PATCH RFC] hwmon: (coretemp) Improve support for
TjMax detection on Atom CPUs

Atom CPUs don't have a register to retrieve TjMax. Detection so far is
incomplete. Use the X86 model ID to improve it.


Thanks for the patch...

Wonder if we can improve TjMax detection for Atom CPUs with this code.
Anyone with Atom CPUs out there for some testing ?

I can test it out on the Medfield platform (Atom based).

You will need Jean's pending patch for that, to detect the new Atom CPU model.

But its Tjmax is 90 C. I don't see any 90 C values in your array.
is there a reason behind it ?

Hi Durga,

If you look closely at the patch, you will notice that the Atom code starts with

    tjmax = 90000;

90 degrees C is thus the default case. The table only includes values for CPUs with a different tjmax. That keeps the table a bit smaller.

Or we can add as we find more models ?

Definitely ...

Thanks,
Guenter
