   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
  14	  on-line as fast as possible after a lock-up. There's both a watchdog
  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
  18	  your computer. For details, read
  19	  <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
  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.
  26
  27	  If unsure, say N.

  35	  This driver provides a framework for all watchdog timer drivers
  36	  and gives them the /dev/watchdog interface (and later also the

  38
  39config WATCHDOG_NOWAYOUT
  40	bool "Disable watchdog shutdown on close"
  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.

   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
  14	  on-line as fast as possible after a lock-up. There's both a watchdog
  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
  18	  your computer. For details, read
  19	  <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
  20
  21	  The watchdog is usually used together with the watchdog daemon
  22	  which is available from

1317	  This is the driver for the Berkshire Products USB-PC Watchdog card.
1318	  This card simply watches your kernel to make sure it doesn't freeze,
1319	  and if it does, it reboots your computer after a certain amount of
1320	  time. The card can also monitor the internal temperature of the PC.
