7 ---help---
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
e0845bf4 14 on-line as fast as possible after a lock-up. There's both a watchdog
1da177e4
LT
15 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
e403149c
DH
18 your computer. For details, read
19 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
1da177e4
LT
20
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
46 it has been started.

1413 This driver adds watchdog support for the integrated watchdog in the
1414 SuperH processors. If you have one of these processors and wish
1415 to have watchdog support enabled, say Y, otherwise say N.
1416
1417 As a side note, saying Y here will automatically boost HZ to 1000
1418 so that the timer has a chance to clear the overflow counter. On
1419 slower systems (such as the SH-2 and SH-3) this will likely yield
1420 some performance issues. As such, the WDT should be avoided here
1421 unless it is absolutely necessary.

1480 This card simply watches your kernel to make sure it doesn't freeze,
1481 and if it does, it reboots your computer after a certain amount of
1482 time. This driver is like the WDT501 driver but for different
1483 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1484 watchdog cards can be ordered from <http://www.berkprod.com/>.
