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

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

Linus Torvalds1da177e2005-04-16 15:20:36 -070020
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.

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

1055 This is the driver for the hardware watchdog on the W83877F chipset
1056 as used in EMACS PC-104 motherboards (and likely others). This
1057 watchdog simply watches your kernel to make sure it doesn't freeze,
1058 and if it does, it reboots your computer after a certain amount of
1059 time.

1061 To compile this driver as a module, choose M here: the
1062 module will be called w83877f_wdt.

1100 is no way to know if writing to its IO address will corrupt
1101 your system or have any real effect. The only way to be sure
1102 that this driver does what you want is to make sure you
Matt LaPlante2621e2a2006-07-05 01:20:51 +00001103 are running it on an EPX-C3 from Winsystems with the watchdog

1106 this driver into your kernel and/or load it as a module, that you

1395 IBM s/390 and zSeries machines running under z/VM 5.1 or later
1396 provide a virtual watchdog timer to their guest that cause a
1397 user define Control Program command to be executed after a
1398 timeout.
Philipp Hachtmann646f9192014-06-05 11:02:36 +02001399 LPAR provides a very similar interface. This driver handles
1400 both.

1412 This driver adds watchdog support for the integrated watchdog in the
1413 SuperH processors. If you have one of these processors and wish
1414 to have watchdog support enabled, say Y, otherwise say N.
1415
1416 As a side note, saying Y here will automatically boost HZ to 1000
1417 so that the timer has a chance to clear the overflow counter. On
1418 slower systems (such as the SH-2 and SH-3) this will likely yield
1419 some performance issues. As such, the WDT should be avoided here
1420 unless it is absolutely necessary.
