| 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. |

| 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 |

| Select the default watchdog timer period to be used by the PowerPC |
| Book-E watchdog driver. A watchdog "event" occurs when the bit |
| position represented by this number transitions from zero to one. |
| |
| For Freescale Book-E processors, this is a number between 0 and 63. |
| For other Book-E processors, this is a number between 0 and 3. |

| to have watchdog support enabled, say Y, otherwise say N. |
| |
| 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 |
