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

1405 Hardware driver for the TCO timer built into the nVidia Hub family
1406 (such as the MCP51). The TCO (Total Cost of Ownership) timer is a
1407 watchdog timer that will reboot the machine after its second
1408 expiration. The expiration time can be configured with the
1409 "heartbeat" parameter.
1410
1411 On some motherboards the driver may fail to reset the chipset's
1412 NO_REBOOT flag which prevents the watchdog from rebooting the
1413 machine. If this is the case you will get a kernel message like
1414 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

1434 This driver can be used with the watchdog timer found on some
1435 single board computers, namely the 6010 PII based computer.
1436 It may well work with other cards. It reads port 0x443 to enable
1437 and re-set the watchdog timer, and reads port 0x45 to disable
1438 the watchdog. If you have a card that behave in similar ways,
1439 you can probably make this driver work with your card as well.
