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.

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

998 Hardware driver for the TCO timer built into the nVidia Hub family

1002 "heartbeat" parameter.
1003
1004 On some motherboards the driver may fail to reset the chipset's
1005 NO_REBOOT flag which prevents the watchdog from rebooting the

1417 This driver is for a SoC level watchdog that exists on some
1418 Freescale PowerPC processors. So far this driver supports:
0d7b1014 1419 - MPC8xx watchdogs
28acd02f
AV
1420 - MPC83xx watchdogs
1421 - MPC86xx watchdogs
1422
1423 For BookE processors (MPC85xx) use the BOOKE_WDT driver instead.

1458 position represented by this number transitions from zero to one.
1459
1460 For Freescale Book-E processors, this is a number between 0 and 63.
1461 For other Book-E processors, this is a number between 0 and 3.

1514 to have watchdog support enabled, say Y, otherwise say N.
1515
1516 As a side note, saying Y here will automatically boost HZ to 1000
1517 so that the timer has a chance to clear the overflow counter. On
1518 slower systems (such as the SH-2 and SH-3) this will likely yield
1519 some performance issues. As such, the WDT should be avoided here
1520 unless it is absolutely necessary.
