463 | kexec is a system call that implements the ability to shutdown your |
464 | current kernel, and to start another kernel. It is like a reboot | |
1f1332f7 | 465 | but it is independent of the system firmware. And like a reboot |
cad82448 PM |
466 | you can start any kernel with it, not just Linux. |
467 | ||
1f1332f7 | 468 | The name comes from the similarity to the exec system call. |

469 | |
470 | It is an ongoing process to be certain the hardware in a machine | |
471 | is properly shutdown, so do not be surprised if this code does not | |
472 | initially work for you. It may help to enable device hotplugging | |
473 | support. As of this writing the exact hardware interface is | |
474 | strongly in flux, so no good recommendation can be made. | |

497 | execution. By using pipes or other transports made available to | |
498 | the process as file descriptors supporting the read/write | |

500 | their own address space using seccomp. Once seccomp is | |
