459 | kexec is a system call that implements the ability to shutdown your |
460 | current kernel, and to start another kernel. It is like a reboot | |
1f1332f7 | 461 | but it is independent of the system firmware. And like a reboot |
cad82448 PM |
462 | you can start any kernel with it, not just Linux. |
463 | ||
1f1332f7 | 464 | The name comes from the similarity to the exec system call. |
cad82448 PM |
465 | |
466 | It is an ongoing process to be certain the hardware in a machine | |
467 | is properly shutdown, so do not be surprised if this code does not | |
468 | initially work for you. It may help to enable device hotplugging | |
469 | support. As of this writing the exact hardware interface is | |
470 | strongly in flux, so no good recommendation can be made. | |

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

479 | a specially reserved region and then later executed after | |
