|  | bool "Watchdog Timer Support" | 
|  | ---help--- | 
|  | If you say Y here (and to one of the following options) and create a | 
|  | character special file /dev/watchdog with major number 10 and minor | 
|  | number 130 using mknod ("man mknod"), you will get a watchdog, i.e.: | 
|  | subsequently opening the file and then failing to write to it for | 
|  | longer than 1 minute will result in rebooting the machine. This | 
|  | could be useful for a networked machine that needs to come back | 
|  | on-line as fast as possible after a lock-up. There's both a watchdog | 
|  | implementation entirely in software (which can sometimes fail to | 
|  | reboot the machine) and a driver for hardware watchdog boards, which | 
|  | are more robust and can also keep track of the temperature inside | 
|  | your computer. For details, read | 
|  | <file:Documentation/watchdog/watchdog-api.txt> in the kernel source. | 
|  |  | 
|  | The watchdog is usually used together with the watchdog daemon | 
|  | which is available from | 
|  | <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can | 
|  | also monitor NFS connections and can reboot the machine when the process | 
|  | table is full. | 
|  |  | 
|  | If unsure, say N. | 
|  |  |

|  | config WATCHDOG_CORE |

|  | ---help--- | 
|  | Say Y here if you want to use the new watchdog timer driver core. | 
|  | This driver provides a framework for all watchdog timer drivers | 
|  | and gives them the /dev/watchdog interface (and later also the | 
|  | sysfs interface). | 
|  |  | 
|  | config WATCHDOG_NOWAYOUT | 
|  | bool "Disable watchdog shutdown on close" | 
|  | help | 
|  | The default watchdog behaviour (which you get if you say N here) is | 
|  | to stop the timer if the process managing it closes the file | 
|  | /dev/watchdog. It's always remotely possible that this process might | 
|  | get killed. If you say Y here, the watchdog cannot be stopped once | 
|  | it has been started. |
