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. | |

855 | Say Y here to support the hardware watchdog capability on Sun RIO | |
856 | machines. The watchdog timeout period is normally one minute but | |
857 | can be changed with a boot-time parameter. | |

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

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

917 | /dev/temperature yields one byte, the temperature in degrees | |
918 | Fahrenheit. This works only if you have a WDT501P watchdog board | |
919 | installed. | |

921 | If you want to enable the Fan Tachometer on the WDT501P, then you | |
