- temperature within 2-4 degrees Celsius. This option shows the current
- on-die temperature in /proc/cpuinfo if the cpu supports it.

-config TAU_INT

- to get notified the temp has exceeded a range. With this option off,
- a timer is used to re-check the temperature periodically.
-
- However, on some cpus it appears that the TAU interrupt hardware
- is buggy and can cause a situation which would lead unexplained hard
- lockups.
-
- Unless you are extending the TAU driver, or enjoy kernel/hardware
- debugging, leave this option off.
-
-config TAU_AVERAGE

- ---help---
- The TAU hardware can compare the temperature to an upper and lower
- bound. 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. If you say Y here, a single temperature value,
- halfway between the upper and lower bounds, will be reported in
- /proc/cpuinfo.
-
- If in doubt, say N here.
