132 | There are four families of PowerPC chips supported. The more common | |

134 | versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the AMCC | |
135 | embedded versions (403 and 405) and the high end 64 bit Power | |
136 | processors (POWER 3, POWER4, and IBM PPC970 also known as G5). | |
650f3289 GL |

138 | This option is the catch-all for 6xx types, including some of the | |
139 | embedded versions. Unless there is see an option for the specific | |
140 | chip family you are using, you want this option. | |
141 | ||
142 | You do not want this if you are building a kernel for a 64 bit | |
143 | IBM RS/6000 or an Apple G5, choose 6xx. | |

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

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

714 | ||
715 | However, on some cpus it appears that the TAU interrupt hardware | |
716 | is buggy and can cause a situation which would lead unexplained hard | |
717 | lockups. | |

729 | either changing a lot, or the TAU hardware is broken (likely on some | |
730 | G4's). If the range is small (around 4 degrees), the temperature is | |
731 | relatively stable. If you say Y here, a single temperature value, | |
732 | halfway between the upper and lower bounds, will be reported in | |

949 | This kernel feature is useful for number crunching applications | |
950 | that may need to compute untrusted bytecode during their | |
951 | execution. By using pipes or other transports made available to | |
952 | the process as file descriptors supporting the read/write | |
953 | syscalls, it's possible to isolate those applications in | |
954 | their own address space using seccomp. Once seccomp is | |
955 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
956 | and the task is only allowed to execute a few safe syscalls | |
957 | defined by each seccomp mode. | |
