bool "Watchdog Timer Support" |

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

|
If unsure, say N. |

help |
|
Say Y here if you want to use the new watchdog timer driver core. |

This driver provides a framework for all watchdog timer drivers |

and gives them the /dev/watchdog interface (and later also the |

sysfs interface). |

config WATCHDOG_NOWAYOUT |

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

config WATCHDOG_HANDLE_BOOT_ENABLED |

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

enough your device will reboot. |

As a side note, saying Y here will automatically boost HZ to 1000 |
|
so that the timer has a chance to clear the overflow counter. On |

slower systems (such as the SH-2 and SH-3) this will likely yield |

some performance issues. As such, the WDT should be avoided here |
