8 bool "Watchdog Timer Support"
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.
23 The watchdog is usually used together with the watchdog daemon
24 which is available from
25 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
26 also monitor NFS connections and can reboot the machine when the process
27 table is full.
29 If unsure, say N.

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

38 and gives them the /dev/watchdog interface (and later also the
39 sysfs interface).
41 config WATCHDOG_NOWAYOUT
42 bool "Disable watchdog shutdown on close"
43 help
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
48 it has been started.
50 config WATCHDOG_HANDLE_BOOT_ENABLED
51 bool "Update boot-enabled watchdog until userspace takes over"

53 help
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.

1951 to have watchdog support enabled, say Y, otherwise say N.
1953 As a side note, saying Y here will automatically boost HZ to 1000
1954 so that the timer has a chance to clear the overflow counter. On
1955 slower systems (such as the SH-2 and SH-3) this will likely yield
1956 some performance issues. As such, the WDT should be avoided here
