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 | |
e0845bf4 | 16 | on-line as fast as possible after a lock-up. There's both a watchdog |
1da177e4 LT |
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 | |
e403149c DH |
20 | your computer. For details, read |
21 | <file:Documentation/watchdog/watchdog-api.txt> in the kernel source. | |
1da177e4 LT |
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. | |

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

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

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

2018 | This is the driver for the Berkshire Products ISA-PC Watchdog card. | |
2019 | This card simply watches your kernel to make sure it doesn't freeze, | |
2020 | and if it does, it reboots your computer after a certain amount of | |
2021 | time. This driver is like the WDT501 driver but for different | |
2022 | hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC | |
2023 | watchdog cards can be ordered from <http://www.berkprod.com/>. | |

2048 | If you have a WDT500P or WDT501P watchdog board, say Y here, | |
2049 | otherwise N. It is not possible to probe for this board, which means | |
2050 | that you have to inform the kernel about the IO port and IRQ that | |
2051 | is needed (you can do this via the io and irq parameters) | |
