780 | depends on EXPERIMENTAL | |
781 | help | |
782 | kexec is a system call that implements the ability to shutdown your | |
783 | current kernel, and to start another kernel. It is like a reboot | |
784 | but it is indepedent of the system firmware. And like a reboot | |
785 | you can start any kernel with it, not just Linux. | |
786 | ||
787 | The name comes from the similiarity to the exec system call. | |
788 | ||
789 | It is an ongoing process to be certain the hardware in a machine | |
790 | is properly shutdown, so do not be surprised if this code does not | |
791 | initially work for you. It may help to enable device hotplugging | |
792 | support. As of this writing the exact hardware interface is | |
793 | strongly in flux, so no good recommendation can be made. | |
