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

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

829 | IBM s/390 and zSeries machines running under z/VM 5.1 or later | |
830 | provide a virtual watchdog timer to their guest that cause a | |
831 | user define Control Program command to be executed after a | |
832 | timeout. | |

842 | help |
843 | This driver adds watchdog support for the integrated watchdog in the | |
844 | SuperH processors. If you have one of these processors and wish | |
845 | to have watchdog support enabled, say Y, otherwise say N. | |
846 | ||
847 | As a side note, saying Y here will automatically boost HZ to 1000 | |
848 | so that the timer has a chance to clear the overflow counter. On | |
849 | slower systems (such as the SH-2 and SH-3) this will likely yield | |
850 | some performance issues. As such, the WDT should be avoided here | |
851 | unless it is absolutely necessary. | |

854 | module will be called shwdt. | |
