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.

55 to ping watchdog devices that were enabled before the driver has
56 been loaded until control is taken over from userspace using the

1397 This driver can be used with the watchdog timer found on some
1398 single board computers, namely the 6010 PII based computer.
1399 It may well work with other cards. It reads port 0x443 to enable
1400 and re-set the watchdog timer, and reads port 0x45 to disable
1401 the watchdog. If you have a card that behave in similar ways,
1402 you can probably make this driver work with your card as well.
1403
1404 You can compile this driver directly into the kernel, or use
1405 it as a module. The module will be called sbc60xxwdt.
