  4. menuconfig WATCHDOG
  5. bool "Watchdog Timer Support"
  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.
  24. If unsure, say N.
  25. if WATCHDOG
  26. config WATCHDOG_CORE
  27. bool "WatchDog Timer Driver Core"
  28. ---help---
  29. Say Y here if you want to use the new watchdog timer driver core.
  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.
  41. config WATCHDOG_HANDLE_BOOT_ENABLED
  42. bool "Update boot-enabled watchdog until userspace takes over"
  43. default y
  44. help
  45. The default watchdog behaviour (which you get if you say Y here) is
  46. to ping watchdog devices that were enabled before the driver has
  47. been loaded until control is taken over from userspace using the
  48. /dev/watchdog file. If you say N here, the kernel will not update
  49. the watchdog on its own. Thus if your userspace does not start fast
  50. enough your device will reboot.
  51. config WATCHDOG_SYSFS
  52. bool "Read different watchdog information through sysfs"
  53. help
  54. Say Y here if you want to enable watchdog device status read through
  55. sysfs attributes.

  64. help
  65. A software monitoring watchdog. This will fail to reboot your system
  66. from some situations that the hardware watchdog will recover
  67. from. Equally it's a lot cheaper to install.
  68. To compile this driver as a module, choose M here: the
  69. module will be called softdog.
  70. config SOFT_WATCHDOG_PRETIMEOUT

  73. help
  74. Enable this if you want to use pretimeout governors with the software
  75. watchdog. Be aware that governors might affect the watchdog because it
