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 | |
32 | bool "Disable watchdog shutdown on close" | |
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. | |

505 | This is the driver for the Berkshire Products ISA-PC Watchdog card. | |
506 | This card simply watches your kernel to make sure it doesn't freeze, | |

508 | time. This driver is like the WDT501 driver but for different | |
509 | hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC | |

536 | otherwise N. It is not possible to probe for this board, which means | |
