528 | kexec is a system call that implements the ability to shutdown your |
529 | current kernel, and to start another kernel. It is like a reboot | |
1f1332f7 | 530 | but it is independent of the system firmware. And like a reboot |
cad82448 PM |
531 | you can start any kernel with it, not just Linux. |
532 | ||
1f1332f7 | 533 | The name comes from the similarity to the exec system call. |
cad82448 PM |
534 | |
535 | It is an ongoing process to be certain the hardware in a machine | |
536 | is properly shutdown, so do not be surprised if this code does not | |
537 | initially work for you. It may help to enable device hotplugging | |
