6 bool "Watchdog Timer Support"
8 If you say Y here (and to one of the following options) and create a
9 character special file /dev/watchdog with major number 10 and minor
10 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
11 subsequently opening the file and then failing to write to it for
12 longer than 1 minute will result in rebooting the machine. 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.
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
31 config WATCHDOG_NOWAYOUT
32 bool "Disable watchdog shutdown on close"
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

49 tristate "Software watchdog"
51 A software monitoring watchdog. This will fail to reboot your system
52 from some situations that the hardware watchdog will recover
53 from. Equally it's a lot cheaper to install.
55 To compile this driver as a module, choose M here: the
56 module will be called softdog.
62 config AT91RM9200_WATCHDOG
63 tristate "AT91RM9200 watchdog"
64 depends on ARCH_AT91RM9200
66 Watchdog timer embedded into AT91RM9200 chips. This will reboot your
67 system when the timeout is reached.

74 reboot your system when the timeout is reached.
77 tristate "DC21285 watchdog"
80 The Intel Footbridge chip contains a built-in watchdog circuit. Say Y
81 here if you wish to use this. Alternatively say M to compile the
82 driver as a module, which will be called wdt285.
84 This driver does not work on all machines. In particular, early CATS
85 boards have hardware problems that will cause the machine to simply
86 lock up if the watchdog fires.

91 tristate "NetWinder WB83C977 watchdog"
92 depends on FOOTBRIDGE && ARCH_NETWINDER
94 Say Y here to include support for the WB977 watchdog included in

762 This driver is for a SoC level watchdog that exists on some
763 Freescale PowerPC processors. So far this driver supports:
768 For BookE processors (MPC85xx) use the BOOKE_WDT driver instead.

787 This driver adds watchdog support for the RTAS watchdog.
789 To compile this driver as a module, choose M here. The module
790 will be called wdrtas.
795 tristate "z/VM Watchdog Timer"
798 IBM s/390 and zSeries machines running under z/VM 5.1 or later
799 provide a virtual watchdog timer to their guest that cause a
800 user define Control Program command to be executed after a

804 will be called vmwatchdog.
806 # SUPERH (sh + sh64) Architecture
809 tristate "SuperH Watchdog"
810 depends on SUPERH && (CPU_SH3 || CPU_SH4)
812 This driver adds watchdog support for the integrated watchdog in the
813 SuperH processors. If you have one of these processors and wish
814 to have watchdog support enabled, say Y, otherwise say N.
816 As a side note, saying Y here will automatically boost HZ to 1000
817 so that the timer has a chance to clear the overflow counter. On
818 slower systems (such as the SH-2 and SH-3) this will likely yield
819 some performance issues. As such, the WDT should be avoided here
820 unless it is absolutely necessary.
822 To compile this driver as a module, choose M here: the
823 module will be called shwdt.
826 bool "Allow mmap of SH WDT"
830 If you say Y here, user applications will be able to mmap the

839 depends on SPARC64 && PCI
841 This is the driver for the hardware watchdog timers present on
842 Sun Microsystems CompactPCI models CP1400 and CP1500.
844 To compile this driver as a module, choose M here: the
845 module will be called cpwatchdog.
847 If you do not have a CompactPCI model CP1400 or CP1500, or
848 another UltraSPARC-IIi-cEngine boardset with hardware watchdog,
849 you should say N to this option.
852 tristate "RIO Hardware Watchdog support"
853 depends on SPARC64 && PCI
855 Say Y here to support the hardware watchdog capability on Sun RIO
856 machines. The watchdog timeout period is normally one minute but
857 can be changed with a boot-time parameter.

869 tristate "Berkshire Products ISA-PC Watchdog"
872 This is the driver for the Berkshire Products ISA-PC Watchdog card.
873 This card simply watches your kernel to make sure it doesn't freeze,
874 and if it does, it reboots your computer after a certain amount of
875 time. This driver is like the WDT501 driver but for different
876 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
877 watchdog cards can be ordered from <http://www.berkprod.com/>.
879 To compile this driver as a module, choose M here: the
880 module will be called pcwd.
882 Most people will say N.

899 tristate "WDT Watchdog timer"
902 If you have a WDT500P or WDT501P watchdog board, say Y here,
903 otherwise N. It is not possible to probe for this board, which means
904 that you have to inform the kernel about the IO port and IRQ that
905 is needed (you can do this via the io and irq parameters)
907 To compile this driver as a module, choose M here: the
908 module will be called wdt.
911 bool "WDT501 features"
914 Saying Y here and creating a character special file /dev/temperature
915 with major number 10 and minor number 131 ("man mknod") will give
916 you a thermometer inside your computer: reading from
917 /dev/temperature yields one byte, the temperature in degrees
918 Fahrenheit. This works only if you have a WDT501P watchdog board
921 If you want to enable the Fan Tachometer on the WDT501P, then you
922 can do this via the tachometer parameter. Only do this if you have a
923 fan tachometer actually set up.

937 This card simply watches your kernel to make sure it doesn't freeze,
