534 | kexec is a system call that implements the ability to shutdown your |
535 | current kernel, and to start another kernel. It is like a reboot | |
1f1332f7 | 536 | but it is independent of the system firmware. And like a reboot |
cad82448 PM |
537 | you can start any kernel with it, not just Linux. |
538 | ||
1f1332f7 | 539 | The name comes from the similarity to the exec system call. |
cad82448 PM |
540 | |
541 | It is an ongoing process to be certain the hardware in a machine | |
542 | is properly shutdown, so do not be surprised if this code does not | |
543 | initially work for you. It may help to enable device hotplugging | |
