help |
|
kexec is a system call that implements the ability to shutdown your |
|
current kernel, and to start another kernel. It is like a reboot |
|
but it is independent of the system firmware. And like a reboot |
|
you can start any kernel with it, not just Linux. |
|
|
|
The name comes from the similarity to the exec system call. |
|
|
|
It is an ongoing process to be certain the hardware in a machine |
|
is properly shutdown, so do not be surprised if this code does not |
|
initially work for you. As of this writing the exact hardware |
|
interface is strongly in flux, so no good recommendation can be |

made. |

Generate crash dump after being started by kexec. |

This should be normally only set in special crash dump kernels |

which are loaded in the main kernel with kexec-tools into |

a specially reserved region and then later executed after |

a crash by kdump/kexec. The crash dump kernel must be compiled |

to a memory address not used by the main kernel using |

This enables support for systems with more than one CPU. If you have |

a system with only one CPU, say N. If you have a system with more |
|
than one CPU, say Y. |
|
|
|
If you say N here, the kernel will run on uni- and multiprocessor |
|
machines, but will use only one CPU of a multiprocessor machine. If |
|
you say Y here, the kernel will run on many, but not all, |
|
uniprocessor machines. On a uniprocessor machine, the kernel |
|
will run faster if you say N here. |
|
|
|
People using multiprocessor machines who say Y here should also say |
|
Y to "Enhanced Real Time Clock Support", below. |

This allows you to specify the maximum number of CPUs which this |

kernel will support. The maximum supported value is 32 and the |

minimum value which makes sense is 2. |

This is purely to save memory - each supported CPU adds |

approximately eight kilobytes to the kernel image. |

Enabling this option will allow the kernel to implement some |

atomic operations using a software implementation of load-locked/ |
