| config WATCHDOG |
| 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 |
| online 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.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_NOWAYOUT |
| bool "Disable watchdog shutdown on close" |
| depends on WATCHDOG |
| 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. |
