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. | |

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

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

1230 | If you have a WDT500P or WDT501P watchdog board, say Y here, | |
1231 | otherwise N. It is not possible to probe for this board, which means | |
1232 | that you have to inform the kernel about the IO port and IRQ that | |
1233 | is needed (you can do this via the io and irq parameters) | |
1234 | ||
1235 | To compile this driver as a module, choose M here: the | |
1236 | module will be called wdt. | |

1249 | This is the driver for the Berkshire Products PCI-PC Watchdog card. | |
1250 | This card simply watches your kernel to make sure it doesn't freeze, | |
1251 | and if it does, it reboots your computer after a certain amount of | |
1252 | time. The card can also monitor the internal temperature of the PC. | |

1266 | If you have a PCI-WDT501 watchdog board then you can enable the |
1267 | temperature sensor by setting the type parameter to 501. | |

1268 | |
1269 | If you want to enable the Fan Tachometer on the PCI-WDT501, then you | |
1270 | can do this via the tachometer parameter. Only do this if you have a | |
1271 | fan tachometer actually set up. | |
