The reboot() uses either acpi_reboot() (when ACPICA support is compiled in) or keyboard_reboot (when i8042 controller is present). It fallbacks to the hard_reboot() as a last resort. The reboot() is called only upon i8042's handled CTRL+ALT+DEL key combination. Signed-off-by: Pawel Wieczorkiewicz <[email protected]>
The UART reboot functionality looks for '+++' character string input received via UART and calls reboot() when detected. Signed-off-by: Pawel Wieczorkiewicz <[email protected]>
In case communication with KTF is not possible (no PS/2 keyboard nor UART port) add an option to automatically reboot after specified amount of time. The reboot_timeout by default is off. Value 0 means reboot immediately. Values unit is seconds. Please note a timer needs to be enabled for this functionality to work. Signed-off-by: Pawel Wieczorkiewicz <[email protected]>
