This option shows the current + on-die temperature in /proc/cpuinfo if the cpu supports it. + + Unfortunately, this sensor is very inaccurate when uncalibrated, so + don't assume the cpu temp is actually what /proc/cpuinfo says it is. + +config TAU_INT + bool "Interrupt driven TAU driver (EXPERIMENTAL)" + depends on TAU + help + The TAU supports an interrupt driven mode which causes an interrupt + whenever the temperature goes out of range.

The default behavior is to show both the upper and lower + bound in /proc/cpuinfo. If the range is large, the temperature is + either changing a lot, or the TAU hardware is broken (likely on some + G4's). If the range is small (around 4 degrees), the temperature is + relatively stable.
