| |
Hi!
This small patch enables the coretemp driver on an Intel Atom. I'm not sure if the readings are correct, however - on my 330, the driver reports values between 27 and 41 °C (with core1 being about 8°C hotter than core0, given the same load). Maybe the maximum temperature of 100 °C is wrong for Atom CPUs.
