8 ---help---
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
e0845bf4 15 on-line as fast as possible after a lock-up. There's both a watchdog
1da177e4
LT
16 implementation entirely in software (which can sometimes fail to
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
e403149c
DH
19 your computer. For details, read
20 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
1da177e4
LT
21
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.

43 The default watchdog behaviour (which you get if you say N here) is
44 to stop the timer if the process managing it closes the file
45 /dev/watchdog. It's always remotely possible that this process might
46 get killed. If you say Y here, the watchdog cannot be stopped once
47 it has been started.

974 The TCO (Total Cost of Ownership) timer is a watchdog timer
975 that will reboot the machine after its second expiration. The
976 expiration time can be configured with the "heartbeat" parameter.
977
978 On some motherboards the driver may fail to reset the chipset's
979 NO_REBOOT flag which prevents the watchdog from rebooting the
980 machine. If this is the case you will get a kernel message like
981 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

1433 Hardware driver for OCTEON's on chip watchdog timer.
1434 Enables the watchdog for all cores running Linux. It
1435 installs a NMI handler and pokes the watchdog based on an
1436 interrupt. On first expiration of the watchdog, the
1437 interrupt handler pokes it. The second expiration causes an
1438 NMI that prints a message. The third expiration causes a
1439 global soft reset.
1440
1441 When userspace has /dev/watchdog open, no poking is done
1442 from the first interrupt, it is then only poked when the
1443 device is written.
