Average high and low temp


Linux Kernel Configuration
└─>Platform support
└─>Average high and low temp
In linux kernel since version 2.6.15 (release Date: 2006-01-02)  
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

If in doubt, say N here.
