This 13 could be useful for a networked machine that needs to come back 14 on-line as fast as possible after a lock-up. There's both a watchdog 15 implementation entirely in software (which can sometimes fail to 16 reboot the machine) and a driver for hardware watchdog boards, which 17 are more robust and can also keep track of the temperature inside 18 your computer. For details, read 19 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source. 20 21 The watchdog is usually used together with the watchdog daemon 22 which is available from 23 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can 24 also monitor NFS connections and can reboot the machine when the process 25 table is full. 26 27 If unsure, say N. 28 29if WATCHDOG 30 31config WATCHDOG_NOWAYOUT 32 bool "Disable watchdog shutdown on close" 33 help 34 The default watchdog behaviour (which you get if you say N here) is 35 to stop the timer if the process managing it closes the file 36 /dev/watchdog. It's always remotely possible that this process might 37 get killed. If you say Y here, the watchdog cannot be stopped once 38 it has been started. 39 40# 41# General Watchdog drivers 42# 43 44comment "Watchdog Device Drivers" 45 46# Architecture Independent 47 48config SOFT_WATCHDOG 49 tristate "Software watchdog" 50 help 51 A software monitoring watchdog.

If you have one of these processors and wish 708 to have watchdog support enabled, say Y, otherwise say N. 709 710 As a side note, saying Y here will automatically boost HZ to 1000 711 so that the timer has a chance to clear the overflow counter. On 712 slower systems (such as the SH-2 and SH-3) this will likely yield 713 some performance issues. As such, the WDT should be avoided here 714 unless it is absolutely necessary. 715 716 To compile this driver as a module, choose M here: the 717 module will be called shwdt. 718 719config SH_WDT_MMAP 720 bool "Allow mmap of SH WDT" 721 default n 722 depends on SH_WDT 723 help 724 If you say Y here, user applications will be able to mmap the 725 WDT/CPG registers. 726 727# SPARC Architecture 728 729# SPARC64 Architecture 730 731config WATCHDOG_CP1XXX 732 tristate "CP1XXX Hardware Watchdog support" 733 depends on SPARC64 && PCI 734 ---help--- 735 This is the driver for the hardware watchdog timers present on 736 Sun Microsystems CompactPCI models CP1400 and CP1500. 737 738 To compile this driver as a module, choose M here: the 739 module will be called cpwatchdog. 740 741 If you do not have a CompactPCI model CP1400 or CP1500, or 742 another UltraSPARC-IIi-cEngine boardset with hardware watchdog, 743 you should say N to this option. 744 745config WATCHDOG_RIO 746 tristate "RIO Hardware Watchdog support" 747 depends on SPARC64 && PCI 748 help 749 Say Y here to support the hardware watchdog capability on Sun RIO 750 machines.
