7 bool "Watchdog Timer Support"
8 ---help---
9 If you say Y here (and to one of the following options) and create a
10 character special file /dev/watchdog with major number 10 and minor
11 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
12 subsequently opening the file and then failing to write to it for
13 longer than 1 minute will result in rebooting the machine. This
14 could be useful for a networked machine that needs to come back
e0845bf4 15 on-line as fast as possible after a lock-up. There's both a watchdog
1da177e4
LT
16 implementation entirely in software (which can sometimes fail to
17 reboot the machine) and a driver for hardware watchdog boards, which
18 are more robust and can also keep track of the temperature inside
e403149c
DH
19 your computer. For details, read
20 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
1da177e4
LT
21
22 The watchdog is usually used together with the watchdog daemon
23 which is available from
24 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
25 also monitor NFS connections and can reboot the machine when the process
26 table is full.

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

43 The default watchdog behaviour (which you get if you say N here) is
44 to stop the timer if the process managing it closes the file
45 /dev/watchdog. It's always remotely possible that this process might
46 get killed. If you say Y here, the watchdog cannot be stopped once
47 it has been started.

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

1829 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1830 This card simply watches your kernel to make sure it doesn't freeze,
1831 and if it does, it reboots your computer after a certain amount of
1832 time. This driver is like the WDT501 driver but for different
1833 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1834 watchdog cards can be ordered from <http://www.berkprod.com/>.
