10 If you say Y here (and to one of the following options) and create a
11 character special file /dev/watchdog with major number 10 and minor
12 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
13 subsequently opening the file and then failing to write to it for
14 longer than 1 minute will result in rebooting the machine. This
15 could be useful for a networked machine that needs to come back
e0845bf4 16 on-line as fast as possible after a lock-up. There's both a watchdog
1da177e4
LT
17 implementation entirely in software (which can sometimes fail to
18 reboot the machine) and a driver for hardware watchdog boards, which
19 are more robust and can also keep track of the temperature inside
e403149c 20 your computer. For details, read
74665686 21 <file:Documentation/watchdog/watchdog-api.rst> in the kernel source.
1da177e4
LT
22
23 The watchdog is usually used together with the watchdog daemon
24 which is available from
01028829
RD
25 <https://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon
26 can also monitor NFS connections and can reboot the machine when the
27 process table is full.

56 been loaded until control is taken over from userspace using the

486 Note: The internal IXP4xx watchdog does a soft CPU reset
487 which doesn't reset any peripherals. There are circumstances
488 where the watchdog will fail to reset the board correctly
489 (e.g., if the boot ROM is in an unreadable state).

1387 Hardware driver for the TCO timer built into the nVidia Hub family
1388 (such as the MCP51). The TCO (Total Cost of Ownership) timer is a
1389 watchdog timer that will reboot the machine after its second
1390 expiration. The expiration time can be configured with the
1391 "heartbeat" parameter.
1392
1393 On some motherboards the driver may fail to reset the chipset's
1394 NO_REBOOT flag which prevents the watchdog from rebooting the
1395 machine. If this is the case you will get a kernel message like
1396 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

1416 This driver can be used with the watchdog timer found on some
1417 single board computers, namely the 6010 PII based computer.
1418 It may well work with other cards. It reads port 0x443 to enable
1419 and re-set the watchdog timer, and reads port 0x45 to disable
1420 the watchdog. If you have a card that behave in similar ways,
1421 you can probably make this driver work with your card as well.
