129 versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the AMCC
130 embedded versions (403 and 405) and the high end 64 bit Power
131 processors (POWER 3, POWER4, and IBM PPC970 also known as G5).
Grant Likely650f3282006-12-04 17:29:13 -0700132
133 This option is the catch-all for 6xx types, including some of the
134 embedded versions. Unless there is see an option for the specific
135 chip family you are using, you want this option.

644 G3 and G4 processors have an on-chip temperature sensor called the
645 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
646 temperature within 2-4 degrees Celsius. This option shows the current
647 on-die temperature in /proc/cpuinfo if the cpu supports it.
648
649 Unfortunately, on some chip revisions, this sensor is very inaccurate

657 The TAU supports an interrupt driven mode which causes an interrupt
658 whenever the temperature goes out of range. This is the fastest way
659 to get notified the temp has exceeded a range. With this option off,
660 a timer is used to re-check the temperature periodically.
661
662 However, on some cpus it appears that the TAU interrupt hardware
663 is buggy and can cause a situation which would lead unexplained hard
664 lockups.
665
666 Unless you are extending the TAU driver, or enjoy kernel/hardware
667 debugging, leave this option off.

673 The TAU hardware can compare the temperature to an upper and lower
674 bound. The default behavior is to show both the upper and lower
675 bound in /proc/cpuinfo. If the range is large, the temperature is
676 either changing a lot, or the TAU hardware is broken (likely on some
677 G4's). If the range is small (around 4 degrees), the temperature is
678 relatively stable. If you say Y here, a single temperature value,
679 halfway between the upper and lower bounds, will be reported in
680 /proc/cpuinfo.
681
682 If in doubt, say N here.
