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