570 kexec is a system call that implements the ability to shutdown your
571 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400572 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800573 you can start any kernel with it, not just Linux.
574
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400575 The name comes from the similarity to the exec system call.

577 It is an ongoing process to be certain the hardware in a machine
578 is properly shutdown, so do not be surprised if this code does not
579 initially work for you. It may help to enable device hotplugging
580 support. As of this writing the exact hardware interface is
581 strongly in flux, so no good recommendation can be made.

609 that may need to compute untrusted bytecode during their
610 execution. By using pipes or other transports made available to
611 the process as file descriptors supporting the read/write

Paul Mundtcad82442006-01-16 22:14:19 -0800707 This option allows you to set the link address offset of the zImage.
708 This can be useful if you are on a board which has a small amount of
709 memory.

723 Selecting this option will wakeup the User Break Controller (UBC) on
724 startup. Although the UBC is left in an awake state when the processor
725 comes up, some boot loaders misbehave by putting the UBC to sleep in a
726 power saving state, which causes issues with things like ptrace().

749 help
750 The Maple Bus is SEGA's serial communication bus for peripherals
751 on the Dreamcast. Without this bus support you won't be able to
752 get your Dreamcast keyboard etc to work, so most users
753 probably want to say 'Y' here, unless you are only using the
754 Dreamcast with a serial line terminal or a remote network
755 connection.
