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. It's always remotely possible that this process might 46 get killed. 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. Thus if your userspace does not start fast 58 enough your device will reboot. 59 60config WATCHDOG_SYSFS 61 bool "Read different watchdog information through sysfs" 62 help 63 Say Y here if you want to enable watchdog device status read through 64 sysfs attributes. 65 66# 67# General Watchdog drivers 68# 69 70comment "Watchdog Device Drivers" 71 72# Architecture Independent 73 74config SOFT_WATCHDOG 75 tristate "Software watchdog" 76 select WATCHDOG_CORE 77 help 78 A software monitoring watchdog.

If you have one of these processors and wish 1788 to have watchdog support enabled, say Y, otherwise say N. 1789 1790 As a side note, saying Y here will automatically boost HZ to 1000 1791 so that the timer has a chance to clear the overflow counter. On 1792 slower systems (such as the SH-2 and SH-3) this will likely yield 1793 some performance issues. As such, the WDT should be avoided here 1794 unless it is absolutely necessary. 1795 1796 To compile this driver as a module, choose M here: the 1797 module will be called shwdt. 1798 1799# SPARC Architecture 1800 1801# SPARC64 Architecture 1802 1803config WATCHDOG_CP1XXX 1804 tristate "CP1XXX Hardware Watchdog support" 1805 depends on SPARC64 && PCI 1806 ---help--- 1807 This is the driver for the hardware watchdog timers present on 1808 Sun Microsystems CompactPCI models CP1400 and CP1500. 1809 1810 To compile this driver as a module, choose M here: the 1811 module will be called cpwatchdog. 1812 1813 If you do not have a CompactPCI model CP1400 or CP1500, or 1814 another UltraSPARC-IIi-cEngine boardset with hardware watchdog, 1815 you should say N to this option. 1816 1817config WATCHDOG_RIO 1818 tristate "RIO Hardware Watchdog support" 1819 depends on SPARC64 && PCI 1820 help 1821 Say Y here to support the hardware watchdog capability on Sun RIO 1822 machines.
