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. 27 28 If unsure, say N. 29 30if WATCHDOG 31 32config WATCHDOG_CORE 33 bool "WatchDog Timer Driver Core" 34 ---help--- 35 Say Y here if you want to use the new watchdog timer driver core. 36 This driver provides a framework for all watchdog timer drivers 37 and gives them the /dev/watchdog interface (and later also the 38 sysfs interface). 39 40config WATCHDOG_NOWAYOUT 41 bool "Disable watchdog shutdown on close" 42 help 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.

If you say Y here, the watchdog cannot be stopped once 47 it has been started. 48 49config WATCHDOG_HANDLE_BOOT_ENABLED 50 bool "Update boot-enabled watchdog until userspace takes over" 51 default y 52 help 53 The default watchdog behaviour (which you get if you say Y here) is 54 to ping watchdog devices that were enabled before the driver has 55 been loaded until control is taken over from userspace using the 56 /dev/watchdog file. If you say N here, the kernel will not update 57 the watchdog on its own.

If you have one of these processors and wish 1824 to have watchdog support enabled, say Y, otherwise say N. 1825 1826 As a side note, saying Y here will automatically boost HZ to 1000 1827 so that the timer has a chance to clear the overflow counter. On 1828 slower systems (such as the SH-2 and SH-3) this will likely yield 1829 some performance issues. As such, the WDT should be avoided here 1830 unless it is absolutely necessary. 1831 1832 To compile this driver as a module, choose M here: the 1833 module will be called shwdt. 1834 1835# SPARC Architecture 1836 1837# SPARC64 Architecture 1838 1839config WATCHDOG_CP1XXX 1840 tristate "CP1XXX Hardware Watchdog support" 1841 depends on SPARC64 && PCI 1842 ---help--- 1843 This is the driver for the hardware watchdog timers present on 1844 Sun Microsystems CompactPCI models CP1400 and CP1500. 1845 1846 To compile this driver as a module, choose M here: the 1847 module will be called cpwatchdog. 1848 1849 If you do not have a CompactPCI model CP1400 or CP1500, or 1850 another UltraSPARC-IIi-cEngine boardset with hardware watchdog, 1851 you should say N to this option. 1852 1853config WATCHDOG_RIO 1854 tristate "RIO Hardware Watchdog support" 1855 depends on SPARC64 && PCI 1856 help 1857 Say Y here to support the hardware watchdog capability on Sun RIO 1858 machines.
