  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.

 28           If unsure, say N.

 36           This driver provides a framework for all watchdog timer drivers

 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.

1533           This driver adds watchdog support for the integrated watchdog in the
1534           SuperH processors. If you have one of these processors and wish
1535           to have watchdog support enabled, say Y, otherwise say N.
1536 
1537           As a side note, saying Y here will automatically boost HZ to 1000
1538           so that the timer has a chance to clear the overflow counter. On
1539           slower systems (such as the SH-2 and SH-3) this will likely yield
1540           some performance issues. As such, the WDT should be avoided here
1541           unless it is absolutely necessary.
1542 
1543           To compile this driver as a module, choose M here: the
1544           module will be called shwdt.

1610           This is the driver for the Berkshire Products ISA-PC Watchdog card.
1611           This card simply watches your kernel to make sure it doesn't freeze,
1612           and if it does, it reboots your computer after a certain amount of
1613           time. This driver is like the WDT501 driver but for different
1614           hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1615           watchdog cards can be ordered from <http://www.berkprod.com/>.
