8 | ---help--- | |
9 | If you say Y here (and to one of the following options) and create a | |
10 | character special file /dev/watchdog with major number 10 and minor | |
11 | number 130 using mknod ("man mknod"), you will get a watchdog, i.e.: | |
12 | subsequently opening the file and then failing to write to it for | |
13 | longer than 1 minute will result in rebooting the machine. This | |
14 | could be useful for a networked machine that needs to come back | |
e0845bf4 | 15 | on-line as fast as possible after a lock-up. There's both a watchdog |
1da177e4 LT |
16 | implementation entirely in software (which can sometimes fail to |
17 | reboot the machine) and a driver for hardware watchdog boards, which | |
18 | are more robust and can also keep track of the temperature inside | |
e403149c DH |
19 | your computer. For details, read |
20 | <file:Documentation/watchdog/watchdog-api.txt> in the kernel source. | |
1da177e4 LT |
21 | |
22 | The watchdog is usually used together with the watchdog daemon | |
23 | which is available from | |
24 | <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can | |
25 | also monitor NFS connections and can reboot the machine when the process | |
26 | table is full. | |

28 | If unsure, say N. | |

34 | ---help--- | |
35 | Say Y here if you want to use the new watchdog timer driver core. | |
36 | This driver provides a framework for all watchdog timer drivers | |
37 | and gives them the /dev/watchdog interface (and later also the | |
38 | sysfs interface). | |

42 | help |
43 | The default watchdog behaviour (which you get if you say N here) is | |
44 | to stop the timer if the process managing it closes the file | |
45 | /dev/watchdog. It's always remotely possible that this process might | |
46 | get killed. If you say Y here, the watchdog cannot be stopped once | |
47 | it has been started. | |

52 | help | |
53 | The default watchdog behaviour (which you get if you say Y here) is | |
54 | to ping watchdog devices that were enabled before the driver has | |
55 | been loaded until control is taken over from userspace using the | |
56 | /dev/watchdog file. If you say N here, the kernel will not update | |
57 | the watchdog on its own. Thus if your userspace does not start fast | |
58 | enough your device will reboot. | |
