It is like a reboot 101 but it is independent of the system firmware. And like a reboot 102 you can start any kernel with it, not just Linux. 103 104 The name comes from the similarity to the exec system call. 105 106 It is an ongoing process to be certain the hardware in a machine 107 is properly shutdown, so do not be surprised if this code does not 108 initially work for you. As of this writing the exact hardware 109 interface is strongly in flux, so no good recommendation can be 110 made. 111 112config BOOTINFO_PROC 113 bool "Export bootinfo in procfs" 114 depends on KEXEC && M68KCLASSIC 115 help 116 Say Y to export the bootinfo used to boot the kernel in a 117 "bootinfo" file in procfs.
