99 bool "kexec system call"
100 depends on M68KCLASSIC
103 kexec is a system call that implements the ability to shutdown your
104 current kernel, and to start another kernel. It is like a reboot
105 but it is independent of the system firmware. And like a reboot
106 you can start any kernel with it, not just Linux.
108 The name comes from the similarity to the exec system call.
110 It is an ongoing process to be certain the hardware in a machine
111 is properly shutdown, so do not be surprised if this code does not
112 initially work for you. As of this writing the exact hardware
113 interface is strongly in flux, so no good recommendation can be
117 bool "Export bootinfo in procfs"
118 depends on KEXEC && M68KCLASSIC
120 Say Y to export the bootinfo used to boot the kernel in a
121 "bootinfo" file in procfs. This is useful with kexec.
