416 G3 and G4 processors have an on-chip temperature sensor called the

418 temperature within 2-4 degrees Celsius. This option shows the current
419 on-die temperature in /proc/cpuinfo if the cpu supports it.
420
421 Unfortunately, on some chip revisions, this sensor is very inaccurate

429 The TAU supports an interrupt driven mode which causes an interrupt
430 whenever the temperature goes out of range. This is the fastest way
431 to get notified the temp has exceeded a range. With this option off,
432 a timer is used to re-check the temperature periodically.
433
434 However, on some cpus it appears that the TAU interrupt hardware
435 is buggy and can cause a situation which would lead unexplained hard
436 lockups.

445 The TAU hardware can compare the temperature to an upper and lower

447 bound in /proc/cpuinfo. If the range is large, the temperature is
448 either changing a lot, or the TAU hardware is broken (likely on some
449 G4's). If the range is small (around 4 degrees), the temperature is
450 relatively stable. If you say Y here, a single temperature value,
451 halfway between the upper and lower bounds, will be reported in
452 /proc/cpuinfo.

519 you can start any kernel with it, not just Linux.
