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
15 on-line as fast as possible after a lock-up. There's both a watchdog
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
19 your computer. For details, read
20 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
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
47 it has been started.

1726 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1727 This card simply watches your kernel to make sure it doesn't freeze,
1728 and if it does, it reboots your computer after a certain amount of
1729 time. This driver is like the WDT501 driver but for different
1730 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1731 watchdog cards can be ordered from <http://www.berkprod.com/>.

1756 If you have a WDT500P or WDT501P watchdog board, say Y here,
1757 otherwise N. It is not possible to probe for this board, which means
1758 that you have to inform the kernel about the IO port and IRQ that
1759 is needed (you can do this via the io and irq parameters)

1790 If you have a PCI-WDT500/501 watchdog board, say Y here, otherwise N.
1791
1792 If you have a PCI-WDT501 watchdog board then you can enable the
1793 temperature sensor by setting the type parameter to 501.
1794
1795 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1796 can do this via the tachometer parameter. Only do this if you have a
1797 fan tachometer actually set up.
