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). | |
650f3289 GL |

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. | |
136 | ||
137 | You do not want this if you are building a kernel for a 64 bit | |
138 | IBM RS/6000 or an Apple G5, choose 6xx. | |

647 | on-die temperature in /proc/cpuinfo if the cpu supports it. | |

657 | The TAU supports an interrupt driven mode which causes an interrupt | |

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. | |

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 | |
