  6. ---help---
  7. If you say Y here (and to one of the following options) and create a
  8. character special file /dev/watchdog with major number 10 and minor
  9. number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
  10. subsequently opening the file and then failing to write to it for
  11. longer than 1 minute will result in rebooting the machine. This
  12. could be useful for a networked machine that needs to come back
  13. on-line as fast as possible after a lock-up. There's both a watchdog
  14. implementation entirely in software (which can sometimes fail to
  15. reboot the machine) and a driver for hardware watchdog boards, which
  16. are more robust and can also keep track of the temperature inside
  17. your computer. For details, read
  18. <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
  19. The watchdog is usually used together with the watchdog daemon
  20. which is available from
  21. <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
  22. also monitor NFS connections and can reboot the machine when the process
  23. table is full.

  30. This driver provides a framework for all watchdog timer drivers
  31. and gives them the /dev/watchdog interface (and later also the
  32. sysfs interface).
  33. config WATCHDOG_NOWAYOUT
  34. bool "Disable watchdog shutdown on close"
  35. help
  36. The default watchdog behaviour (which you get if you say N here) is
  37. to stop the timer if the process managing it closes the file
  38. /dev/watchdog. It's always remotely possible that this process might
  39. get killed. If you say Y here, the watchdog cannot be stopped once
  40. it has been started.
