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