9 | ---help--- | |
10 | If you say Y here (and to one of the following options) and create a | |
11 | character special file /dev/watchdog with major number 10 and minor | |
12 | number 130 using mknod ("man mknod"), you will get a watchdog, i.e.: | |
13 | subsequently opening the file and then failing to write to it for | |
14 | longer than 1 minute will result in rebooting the machine. This | |
15 | could be useful for a networked machine that needs to come back | |
16 | online as fast as possible after a lock-up. There's both a watchdog | |
17 | implementation entirely in software (which can sometimes fail to | |
18 | reboot the machine) and a driver for hardware watchdog boards, which | |
19 | are more robust and can also keep track of the temperature inside | |
20 | your computer. For details, read <file:Documentation/watchdog/watchdog.txt> | |
21 | in the kernel source. | |
22 | ||
23 | The watchdog is usually used together with the watchdog daemon | |
24 | which is available from | |
25 | <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can | |
26 | also monitor NFS connections and can reboot the machine when the process | |
27 | table is full. | |
28 | ||
29 | If unsure, say N. | |

31 | config WATCHDOG_NOWAYOUT | |

33 | depends on WATCHDOG | |
34 | help | |
35 | The default watchdog behaviour (which you get if you say N here) is | |
36 | to stop the timer if the process managing it closes the file | |
37 | /dev/watchdog. It's always remotely possible that this process might | |
38 | get killed. If you say Y here, the watchdog cannot be stopped once | |
39 | it has been started. | |

493 | Hardware driver for the Indy's/I2's watchdog. This is a | |

518 | This driver adds watchdog support for the integrated watchdog in the | |
519 | SuperH processors. If you have one of these processors and wish | |
520 | to have watchdog support enabled, say Y, otherwise say N. | |
521 | ||
522 | As a side note, saying Y here will automatically boost HZ to 1000 | |
523 | so that the timer has a chance to clear the overflow counter. On | |
524 | slower systems (such as the SH-2 and SH-3) this will likely yield | |
525 | some performance issues. As such, the WDT should be avoided here | |
526 | unless it is absolutely necessary. | |
