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

Linus Torvalds1da177e2005-04-16 15:20:36 -070015 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

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

699 Hardware driver for the TCO timer built into the nVidia Hub family
700 (such as the MCP51). The TCO (Total Cost of Ownership) timer is a
701 watchdog timer that will reboot the machine after its second
702 expiration. The expiration time can be configured with the
703 "heartbeat" parameter.
704
705 On some motherboards the driver may fail to reset the chipset's
706 NO_REBOOT flag which prevents the watchdog from rebooting the
707 machine. If this is the case you will get a kernel message like
708 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

727 This driver can be used with the watchdog timer found on some
728 single board computers, namely the 6010 PII based computer.
729 It may well work with other cards. It reads port 0x443 to enable
730 and re-set the watchdog timer, and reads port 0x45 to disable
731 the watchdog. If you have a card that behave in similar ways,
732 you can probably make this driver work with your card as well.

1038 Hardware driver for OCTEON's on chip watchdog timer.
1039 Enables the watchdog for all cores running Linux. It
1040 installs a NMI handler and pokes the watchdog based on an
1041 interrupt. On first expiration of the watchdog, the
1042 interrupt handler pokes it. The second expiration causes an
1043 NMI that prints a message. The third expiration causes a
1044 global soft reset.
1045
1046 When userspace has /dev/watchdog open, no poking is done
1047 from the first interrupt, it is then only poked when the
1048 device is written.
