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

1060 This is the driver for the hardware watchdog on the W83977F I/O chip
1061 as used in AAEON's PCM-5335 SBC (and likely others). This
1062 watchdog simply watches your kernel to make sure it doesn't freeze,
1063 and if it does, it reboots your computer after a certain amount of
1064 time.

1066 To compile this driver as a module, choose M here: the
1067 module will be called w83977f_wdt.

1086 This is the driver for the built-in watchdog timer on the EPX-C3
1087 Single-board computer made by Winsystems, Inc.
1088
1089 *Note*: This hardware watchdog is not probeable and thus there
1090 is no way to know if writing to its IO address will corrupt
1091 your system or have any real effect. The only way to be sure
1092 that this driver does what you want is to make sure you
Matt LaPlante2621e2a2006-07-05 01:20:51 +00001093 are running it on an EPX-C3 from Winsystems with the watchdog
Calin A. Culianueed65652006-01-14 13:20:46 -08001094 timer at IO address 0x1ee and 0x1ef. It will write to both those
1095 IO ports. Basically, the assumption is made that if you compile
1096 this driver into your kernel and/or load it as a module, that you
1097 know what you are doing and that you are in fact running on an
1098 EPX-C3 board!

1385 IBM s/390 and zSeries machines running under z/VM 5.1 or later
1386 provide a virtual watchdog timer to their guest that cause a
1387 user define Control Program command to be executed after a
1388 timeout.
Philipp Hachtmann646f9192014-06-05 11:02:36 +02001389 LPAR provides a very similar interface. This driver handles
1390 both.

1402 This driver adds watchdog support for the integrated watchdog in the
1403 SuperH processors. If you have one of these processors and wish
1404 to have watchdog support enabled, say Y, otherwise say N.
1405
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.
