6 bool "Watchdog Timer Support"
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
14 on-line as fast as possible after a lock-up. There's both a watchdog
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
18 your computer. For details, read
19 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
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.

32 bool "WatchDog Timer Driver Core"
33 ---help---
34 Say Y here if you want to use the new watchdog timer driver core.
35 This driver provides a framework for all watchdog timer drivers
36 and gives them the /dev/watchdog interface (and later also the
37 sysfs interface).
38
39config WATCHDOG_NOWAYOUT
40 bool "Disable watchdog shutdown on close"
41 help
42 The default watchdog behaviour (which you get if you say N here) is
43 to stop the timer if the process managing it closes the file
44 /dev/watchdog. It's always remotely possible that this process might
45 get killed. If you say Y here, the watchdog cannot be stopped once
46 it has been started.

1137 Select the default watchdog timer period to be used by the PowerPC
1138 Book-E watchdog driver. A watchdog "event" occurs when the bit
1139 position represented by this number transitions from zero to one.
1140
1141 For Freescale Book-E processors, this is a number between 0 and 63.
1142 For other Book-E processors, this is a number between 0 and 3.
1143
1144 The value can be overridden by the wdt_period command-line parameter.

1177 help
1178 This driver adds watchdog support for the integrated watchdog in the
1179 SuperH processors. If you have one of these processors and wish
1180 to have watchdog support enabled, say Y, otherwise say N.
1181
1182 As a side note, saying Y here will automatically boost HZ to 1000
1183 so that the timer has a chance to clear the overflow counter. On
1184 slower systems (such as the SH-2 and SH-3) this will likely yield
1185 some performance issues. As such, the WDT should be avoided here
1186 unless it is absolutely necessary.
