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 1804 to have watchdog support enabled, say Y, otherwise say N. 1805 1806 As a side note, saying Y here will automatically boost HZ to 1000 1807 so that the timer has a chance to clear the overflow counter. On 1808 slower systems (such as the SH-2 and SH-3) this will likely yield 1809 some performance issues. As such, the WDT should be avoided here 1810 unless it is absolutely necessary. 1811 1812 To compile this driver as a module, choose M here: the 1813 module will be called shwdt. 1814 1815# SPARC Architecture 1816 1817# SPARC64 Architecture 1818 1819config WATCHDOG_CP1XXX 1820 tristate "CP1XXX Hardware Watchdog support" 1821 depends on SPARC64 && PCI 1822 ---help--- 1823 This is the driver for the hardware watchdog timers present on 1824 Sun Microsystems CompactPCI models CP1400 and CP1500. 1825 1826 To compile this driver as a module, choose M here: the 1827 module will be called cpwatchdog. 1828 1829 If you do not have a CompactPCI model CP1400 or CP1500, or 1830 another UltraSPARC-IIi-cEngine boardset with hardware watchdog, 1831 you should say N to this option. 1832 1833config WATCHDOG_RIO 1834 tristate "RIO Hardware Watchdog support" 1835 depends on SPARC64 && PCI 1836 help 1837 Say Y here to support the hardware watchdog capability on Sun RIO 1838 machines.
