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 | 20 | your computer. For details, read |
74665686 | 21 | <file:Documentation/watchdog/watchdog-api.rst> in the kernel source. |
1da177e4 LT |
22 | |
23 | The watchdog is usually used together with the watchdog daemon | |
24 | which is available from | |
01028829 RD |
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. | |

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

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 | |
59 | enough your device will reboot. | |

1282 | The TCO (Total Cost of Ownership) timer is a watchdog timer | |
1283 | that will reboot the machine after its second expiration. The | |

1286 | On some motherboards the driver may fail to reset the chipset's | |
1287 | NO_REBOOT flag which prevents the watchdog from rebooting the | |

1da177e4 | 1597 | If you are using a ZF Micro MachZ processor, say Y here, otherwise |
e0845bf4 | 1598 | N. This is the driver for the watchdog timer built-in on that |
1da177e4 LT |
1599 | processor using ZF-Logic interface. This watchdog simply watches |
1600 | your kernel to make sure it doesn't freeze, and if it does, it | |
1601 | reboots your computer after a certain amount of time. | |

1610 | This is the driver for the built-in watchdog timer on the EPX-C3 |
1611 | Single-board computer made by Winsystems, Inc. | |
1612 | ||
1613 | *Note*: This hardware watchdog is not probeable and thus there | |
1614 | is no way to know if writing to its IO address will corrupt | |
1615 | your system or have any real effect. The only way to be sure | |
1616 | that this driver does what you want is to make sure you | |
2621e2a1 | 1617 | are running it on an EPX-C3 from Winsystems with the watchdog |
eed6565f CC |
1618 | timer at IO address 0x1ee and 0x1ef. It will write to both those |
1619 | IO ports. Basically, the assumption is made that if you compile | |
1620 | this driver into your kernel and/or load it as a module, that you | |
1621 | know what you are doing and that you are in fact running on an | |
1622 | EPX-C3 board! | |
