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