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

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

Linus Torvalds1da177e2005-04-16 15:20:36 -070021
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.

1090 It`s possible to enable watchdog timer either from BIOS (F2) or from booted Linux.
1091 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.
1092
1093 Entering BIOS setup temporary disables watchdog operation regardless to current state,
1094 so system will not be restarted while user in BIOS setup.
1095
1096 Once watchdog was enabled the system will be restarted every

1360 This driver can be used with the watchdog timer found on some
1361 single board computers, namely the 6010 PII based computer.
1362 It may well work with other cards. It reads port 0x443 to enable
1363 and re-set the watchdog timer, and reads port 0x45 to disable
1364 the watchdog. If you have a card that behave in similar ways,
1365 you can probably make this driver work with your card as well.
1366
1367 You can compile this driver directly into the kernel, or use
1368 it as a module. The module will be called sbc60xxwdt.

1691 Hardware driver for OCTEON's on chip watchdog timer.
1692 Enables the watchdog for all cores running Linux. It
1693 installs a NMI handler and pokes the watchdog based on an
1694 interrupt. On first expiration of the watchdog, the
1695 interrupt handler pokes it. The second expiration causes an
1696 NMI that prints a message. The third expiration causes a
1697 global soft reset.
1698
1699 When userspace has /dev/watchdog open, no poking is done
1700 from the first interrupt, it is then only poked when the
1701 device is written.

2000 minute but can be changed with a boot-time parameter.

2017 This is the driver for the Berkshire Products ISA-PC Watchdog card.
2018 This card simply watches your kernel to make sure it doesn't freeze,
2019 and if it does, it reboots your computer after a certain amount of
2020 time. This driver is like the WDT501 driver but for different
2021 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
2022 watchdog cards can be ordered from <http://www.berkprod.com/>.

2047 If you have a WDT500P or WDT501P watchdog board, say Y here,
2048 otherwise N. It is not possible to probe for this board, which means

2050 is needed (you can do this via the io and irq parameters)
