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
e0845bf4 14 on-line as fast as possible after a lock-up. There's both a watchdog
1da177e4
LT
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
e403149c
DH
18 your computer. For details, read
19 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.

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.

27 If unsure, say N.

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

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.

1406 As a side note, saying Y here will automatically boost HZ to 1000
1407 so that the timer has a chance to clear the overflow counter. On
1408 slower systems (such as the SH-2 and SH-3) this will likely yield
1409 some performance issues. As such, the WDT should be avoided here
1410 unless it is absolutely necessary.

1412 To compile this driver as a module, choose M here: the
1413 module will be called shwdt.

1468 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1469 This card simply watches your kernel to make sure it doesn't freeze,
1470 and if it does, it reboots your computer after a certain amount of
1471 time. This driver is like the WDT501 driver but for different
1472 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1473 watchdog cards can be ordered from <http://www.berkprod.com/>.
