| 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 | on-line 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 |
| 21 | <file:Documentation/watchdog/watchdog-api.rst> in the kernel source. |
| 22 | |
| 23 | The watchdog is usually used together with the watchdog daemon |
| 24 | which is available from |
| 25 | <https://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon |
| 26 | can also monitor NFS connections and can reboot the machine when the |
| 27 | process table is full. |
| 28 | |
| 29 | If unsure, say N. |

| 44 | The default watchdog behaviour (which you get if you say N here) is |

| 46 | /dev/watchdog. It's always remotely possible that this process might |

| 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 |

| 2301 | If you have a PCI-WDT501 watchdog board then you can enable the |
| 2302 | temperature sensor by setting the type parameter to 501. |
| 2303 | |
| 2304 | If you want to enable the Fan Tachometer on the PCI-WDT501, then you |
| 2305 | can do this via the tachometer parameter. Only do this if you have a |
| 2306 | fan tachometer actually set up. |

| 2322 | This is the driver for the Berkshire Products USB-PC Watchdog card. |
| 2323 | This card simply watches your kernel to make sure it doesn't freeze, |
| 2324 | and if it does, it reboots your computer after a certain amount of |
| 2325 | time. The card can also monitor the internal temperature of the PC. |
