6 bool "Watchdog Timer Support"
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.

33 ---help---
34 Say Y here if you want to use the new watchdog timer driver core.

36 and gives them the /dev/watchdog interface (and later also the

41 help
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.

1422 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1423 This card simply watches your kernel to make sure it doesn't freeze,
1424 and if it does, it reboots your computer after a certain amount of
1425 time. This driver is like the WDT501 driver but for different
1426 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1427 watchdog cards can be ordered from <http://www.berkprod.com/>.

1452 If you have a WDT500P or WDT501P watchdog board, say Y here,
1453 otherwise N. It is not possible to probe for this board, which means
1454 that you have to inform the kernel about the IO port and IRQ that
1455 is needed (you can do this via the io and irq parameters)

1472 This card simply watches your kernel to make sure it doesn't freeze,
1473 and if it does, it reboots your computer after a certain amount of

1488 If you have a PCI-WDT501 watchdog board then you can enable the
1489 temperature sensor by setting the type parameter to 501.

1491 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1492 can do this via the tachometer parameter. Only do this if you have a
1493 fan tachometer actually set up.
