7 bool "Watchdog Timer Support"
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.

34 ---help---
35 Say Y here if you want to use the new watchdog timer driver core.
36 This driver provides a framework for all watchdog timer drivers
37 and gives them the /dev/watchdog interface (and later also the
38 sysfs interface).

42 help
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.

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

1455 This driver adds watchdog support for the integrated watchdog in the
1456 SuperH processors. If you have one of these processors and wish
1457 to have watchdog support enabled, say Y, otherwise say N.
1458
1459 As a side note, saying Y here will automatically boost HZ to 1000
1460 so that the timer has a chance to clear the overflow counter. On
1461 slower systems (such as the SH-2 and SH-3) this will likely yield
1462 some performance issues. As such, the WDT should be avoided here
1463 unless it is absolutely necessary.
